The Fuse holder is wired backwards in the first place.

According to their website, that thing is $725. Somebody got robbed.

It looks like "Donkey Stomper" is basically doing the same thing with his CB amplifier power supplies.

News Alert: "The World Starts to turn Again....Mike Posts New Video". 😂

I been running those cheap Chinese knock off supplies for years here with no issues. You do have to blow the dust outta them once in a while...they work great!

X-Farce needs to be shut down.

Arlyn ran that brand into the ground...

Really glad to see you post again Mike. I really enjoy and learn a lot from your videos! Buddy You know... I wanted to see several parts of this again and I have to tell you, when I went back to revisit them I realized that your relations and exclamations are just priceless in this video. It’s tremendously entertaining just to listen to your explanations. Thank you for not only a educational video but a fun one too.

Maybe it says something about my life, but I love nothing more on a Saturday night than a good Mike rant. Thanks for expending your time and energy to potentially save someone's life. Cheers, Mike!

You nailed it! This is worse than a hobbyist nightmare of a home brew.

Hello Mike Mister gatekeeper here I want to thank you highly for the video and I am man enough to admit that I have made more than one of these mistakes that you have pointed out in this video in the past which I have since corrected. Also I am humble enough to admit that you have even pointed out a thing or two that I can improve on myself this was a very informative video. Sitting back and looking at the big picture I just cannot fathom mentally that this was actually built at X-Force or at least I'm wanting to give them the benefit of the doubt and say that maybe someone gutted that X-Force case and built that in there themselves but there again no one really knows but the person who built it and the person who obtained it from that person. It was really cool that you shared the information on the current sharing techniques using diodes and resistors I just recently had to learn these techniques to share boost converters that were not designed to be ran in that fashion I believe there's nothing wrong with using power supplies in that manner as long as they are current shared the proper way cuz I do understand purchasing power supply white mean Wells can be very costly but you are right about the server supplies being built like absolute tanks I have been using these HP 75 amp supplies that only cost $20 a piece used for my self and even though they are used like you mentioned they are built like tanks and built to be ran 24 hours a day and even with them they have one simple small pin for current sharing and all you have to do is simply daisy chain these supplies you are using with a wire 1 pin to the next and it works like a charm. Comment about them jumping the individual fuses this is something I have seen other builders do as well and the whole meaning behind it is they feel if there are going to use one fuse on the box then all of the individual fuses need to be eliminatedbecause there is a problem with one supply it will not be enough to throw the main fuse but there again if you think about it eliminating all of the fuses for there to be a problem big enough to throw that main fuse from an issue with the power supplies themselves you would have to have an issue with pretty much all of the power supplies at once LOL so I think it is best to leave the fuses on each individual supply because if something does happen that one's supply will be able to be inoperative while the others are still working all this just is issues you have with using something in a way that it wasn't designed for well I will admit power supply builders have come a long way with using these individual modules the most proper way that you can use them and I have built a few of them myself which is still in operation but just like you mentioned you have to go the extra mile you have all the extra safety feature that you possibly can have and there again is best if you or building anything at the 200-amp Mark or bigger needs to get go to 220 volt bar none Again very informative video. Thanks, Gatekeeper

They were charging $700 + shipping for that box of horrors. Wow!!

SUNTAN ,,,,,,,,,, that's what you'll get when it bursts into flames !!!!! I'm still laughing!! :) 39:18

First I'd like to thank you for possibly saving someone's life (including your own.) Kudos for calling it like you saw it. Unlike other "technicians" who'd have no problem taking this extremely poor excuse for an amplifier power supply and squeezing the owner for who knows how much $ in order to solder that wire a back on without so much as a word about the dangers this power supply can potentially cause. Let's call a spade a spade. These power supplies are built for nothing more then running Large mobile class C amplifiers in a base station setting. Large mobile class C amplifiers that are built with the same lack of quality and or safety in mind. I'll try my best to stay on topic and won't go into the full line of X-FORCE equipment. I'm not going to slam anyone for owning anything X FORCE. To each his own. On the other hand there's enough information at the finger tip of anyone looking to purchase a 200 amp power supply. And the online consensus (radio hobbyist forms) shows that X FORCE is a company that makes JUNK! And this clip confirms what many already know. I am totally disgusted that any company whether it's a 200000 square foot factory or two knuckleheads in a garage building and knowingly selling a piece of equipment that is so poorly built it's not only a danger to the person who's using it but also puts In harm's way the families living under the same roof in which that piece of equipment is going to be used. I don't know why people don't use the technology available before purchasing anyting. When I say anything I mean anything from A to Z. I find it hard to believe that anyone would purchase a 200 amp power supply from xforce. There are options. And extremely good options if one should need a 200 amp power supply. Megawatt makes a 50 amp power supply that can be run in parallel. The megawatt 50 amp S-700-12 has one of the highest ratings on eham when it comes to power supplies. The poor excuse xforce 200 amp power supply in your clip was initially sold for approximately $700 (including shipping.) Four of the megawatt 50 amp power supplies are $110 ea. (free shipping) and as I mentioned above can be run in parallel creating 200 clean amps. Megawatts power supply filtering is almost second to none in that $110 price range. Not to mention built to the highest standards and quality control that should be expected when a company builds something that can easily take someone's life. It truly is appalling. I didn't even have to tap the small arrow icon in order to read your full description. I knew what you would see when you removed the cover from this power supply. The company name xforce says it all. Its reputation for building junk exceeds it's attempt to take advantage of people that get into the hobby and immediately want to run 2-5kw's (or more) through their antennas. I can't begin to imagine how many of these power supplies have been sold and are being used in households where there are innocent family members (especially children) residing in those houses. I have been doing business with you (Mike) for approximately four years now and we have spent several hours telecommunicating over that period. I know when you're laughing because something is funny and I know when you're laughing because it's all you can do to stop you from crying. I jest of course. But we all know that this is not a joke! If you love your life and the lives of your family members and enjoy your hobby please do your due diligence before purchasing anyting that supplies lethal voltages and can possibly be a fire hazard. As I mentioned above the information is at your fingertips. And there is absolutely no excuse for purchasing any power supply offered by X FORCE (and other like companies.) No one wants to die so they can enjoy their hobby. A hobby should be something that's educational and enjoyable at the same time. And CB radio is that hobby many of us are interested in and enjoy immensely. There are many forms online such as worldwide DX that have a searchable database that will let you know from the people in the know what's good and what isn't. Not to mention a simple Google search. I hope this clip gets shared so many times that it hits a million views. Just because something has a fancy-looking box with a shiny sticker on it doesn't mean it's good. Nor does it mean it's safe. This power supply is obviously a death trap in the making. My advice to the owner would be to scrap it. Enjoy the hobby without worrying about electrocuting yourself or possibly burning down your house and ending the lives of your whole family. I can't imagine anything worse then the possibility of something like that happening. And this power supply is one that might bring you as close to the brink of death then you've ever been before or ever will be until the Lord calls your number (naturally and at a ripe old age.) I can't think of a worse way to go then to get electrocuted or burn alive. Once again Mike kudos. Thanks for your honesty. It wouldn't surprise me if xforce fans or representative weights in and comes up with some cockamamie excuse about this power supply not being built by xforce. or that it was modified by some golden screwdriver. It wasn't modified by a golden screwdriver. It was built by one. And that golden screwdriver is xforce itself. They've got the gall to use the word proprietary in the description of their 11 meter equipment. What a joke! 73 PS. If I'm wrong about using the four megawatt 50 amp power supplies in parallel to do the same thing this xforce 200 amp piece of junk is supposed to do then I apologize for my lack of knowledge. If that's not going to work there are definitely other options for a 200 amp power supply. Options that are safe and well built.

I've shared your video everywhere. Your saving lives.

Besides the horror show, this was a great safety lesson. Thanks especially for that. I learned a lot.

That's right Rooster , Duke E Smears rebuilt Power Supply and I give it the yellow mod before you sold to Charlie Brown

I can see this video been used in a law suit in the Usa..glad your back mike .keep the video comming

Thank arlan... mike how do I get a hold of you to send my tram titan1 to?!

Thanks for exposing this kind of junk that people are unknowingly purchasing.

Hi Mike, Have any experience with MegaWatt power supplies? I bought two S-700-12 50A to parallel for 100A. I have an RM Italy HLA 300 Plus HF amplifier I want to power with those supplies.

Appears they still have a 100A supply available...wonder what it looks like inside. Ouch...

Is this generally true of the types of radio equipment seen in these generic looking aluminum boxes be it amps or whatever? As a person who's interest in radio begins and ends with monitoring there are a few amp builders and radio tuners I watch out of curiosity and have often wondered if what Im watching is sound enginering?

good afternoon i would like to know do you work on tubes types amplifier

You are to see there 2 by 8 amplifiers with the switching power supplies in them

i got a couple of cb mics first one is Cobra Electronics HG-M75 uses a battery and second one is a liberty both are 4 pins can you switch them over to 6 pins and how much would it cost grand total

I had to watch this clip again. Mike's amazement @ the poor build quality (understatement) of this power supply is priceless!! Not to mention he wouldn't even plug it in. REMARKABLE! I think it's only the second time he (Mike) wouldn't plug a device in. And the first time he said he was going to add a DON'T USE THIS DEVICE sticker. I don't think he was joking and I'd bet 2 to 1 he actually added that sticker.

OMG! Many times over, where's the UL sticker, LOL!. Just one minor input on the fuse holder, I always bring my line voltage in the back of the fuse holder, not the side where it can touched when removing or reinstalling the fuse. Another shock hazard right to chassis ground.

Hi Mike, I think BBI built a 300A supply using 30A Mean Well supplies in parallel. I think they were setup for 230V input and he dressed all the wiring so each individual supply had the same length of wiring to help balance the load.

Even server powers supplies, some I think, are even "Hot Swap". Meaning you can take one out that has failed and put in another one. Also usually have over rating for the outputs and such.

That looks like something one of those half-assed Preppers would build after "learning electronics" from, ...you guessed it: ...UKposts.

Sooooooo what I should purchase one of these

Thinking that you should do the same evaluation of the X-Force amps that was supposed to supply....just sayin... I actually have one of their RF amps, I have never used it, but someone recommended it to me so I bought on and then my circumstances changed radically and so I never hooked it up. So after watching this...I am now wondering if the AM RF amp is just as bad???

I've heard so much bad things about xfarce now i see why.

The outputs didn't all have the same length wire, also necessary for load balancing. It makes me shutter to see that abomination. The one BBi built was a 300A 230V input switcher with 6 50A mean-well all adjusted to within .1 volt in the same cab with the amp deck. Great vid, thx.

A Greenlee 1/2 inch D hole punch runs about $215 or more brand new. As a business you could write that off on your taxes, but for someone home brewing their own equipment I'd find a cheaper way to mount a fuse. Maybe a different style of fuse holder.

Scary stuff. Very unsafe! I would not even give it away.

Charlie Brown send you the Power Supply?

That power supply was built by the owners that bought Xforce after carl owned it. Carl himself made and still makes good products.

Live should be on the back of that fuse holder way it is ac straight to chassis ,Mike did he buy it from X force? Or bought it used?

My son s friend s are always useing my garage they bring there cars in to use my tools and tire machine . He knows my rule is the very first thing that has to be done it unhook battery. You would not believe how many of the cars that have a big amp in the trunk and a big wire running out of the hood through the door and under the seat .and when you look at the battery hook up there is no fuse

Hey bud... In the aftermarket CB world that thing is TOP NOTCH!!!

I have a couple astrons power supply but they are not crammed in like that

Yep that's the Power Supply Duke E Smears rebuilt and I sold it to Charlie Brown

Well.....that was fun. Thanks for the info. The thing about those cheap manufacturers like that in China is, "take the money and run". Because what are you going to do? You can't sue, you can't return it, and you'll never get your money back.

Their web page lists them up to 3500 amp, output voltages 11 to 16 v. No pics of inside so don't know if they still assemble them like that. That is BAD!!

I got dooped by him on a 2x8 amp. It worked for a few day and blew a resistor. I had it rebuilt with HG transistors and it works great now.

Nice one ... this would be nice to connect in Europe with a none specific ground pin :-)

You forgot the relay with the NC terminals chopped off by some brute force. Look at it this way, you have a nice case, sort of decent power cord ( though I doubt the 15A rating on it) and some 12V 10A power supplies to use, plus a cheap LED voltmeter.

From the X-Force web page-- "All products are sold for use as testing fixtures for RF transistors, MOSFET Devices, Vacuum tubes, etc in the export market, also for educational use, or even use as a conversation piece to put up on your shelf and and bullshit about with your friends, and Never use these items for anything other than that. And please follow all local, state, and federal laws when opperating any and all electronic equipment." -- Seriously??

Unbelivable!

2019 and nwo 2021 and I''m watching this

That thing is scary. The fact that I have seen other UKposts channels working on them makes me wonder. I guess I know why the channel that was working on it did not show the inside.

Astron has there terminal at chassis level no isolation BTW you missed the line load was backwards on the fuse holder

A stunning bit of kit ,lol

Are mega watt supply any good?

Possiby=Possibly. Wolds=Worlds.

I can only assume that the experience of opening this for the first time was akin to that of opening Pandora's box, which is why there is no footage of the event.

Dont like rants on builders, but y agree on this one...

Mike that supply is at it's oldest from 2014 the power supplies inside had manufacturing date of 2014

What was the cost of this unit new?

Mike LMAO I have been telling people about this for years. I have seen similar boxes claiming 350amp @ 13.8v DC that plug into a 15amp 120v outlet. The truth is I have been told multiple times I don't understand the magic/technology they used. My favorite thing is when, they say something like it can do it because its unregulated lol , this of course has nothing to do with it. Good video man hope it doesn't fall on def ears.

what was the purpose of the wire links across those fuses ?

Joe Snuffy is offended now . I been waiting for a few videos great job as always

Can anyone tell me how I can get in touch with Mike?

This crap does not surprise me at all. The whole outlaw 10 meter amp world is all very sketchy. All of the "builders" claim they're better than each other and I've watched many of their finger-pointing videos and many of the fingers seem to point towards the "blue label" X Force product. Every one of these "builders" have a disclaimer mentioning that their products are not intended for what they are actually intended for. It's like selling narcotics as sculpture art and some of these guys appear to be on meth. I know there are a few "box builders"like BBI who seem to care about safety but it's still of questionable legality. Strange world these CB dudes occupy.

I'd love to see if you cod find a date stamp on any component. It would be interesting to see if this is a current design. His "200a" power supply currently sells for $750. Hilariously it boasts "load sharing". Of course load sharing means nothing. Load balancing is probably what he was trying to lie about. I really want to see this think hooked to a 200a load of course you'd have to use a beefy circuit to power it (probably for about 5 seconds.)

But you're forgetting. Ancient Chinese Secret Invention... CORD IS FUSE!

Not a rant but a PSA on what not to have in a power supply.

"The brown wire..." That about covers it.

Makes a good paper weight.

It’s inversely proportional; if it was directly proportional, then one (variable) would go up as another goes up - i.e. y = a*x, where a is a constant. In a case where it’s inversely proportional, then you have y = a / x, where a is a constant (here, constant power), x is voltage, and y is current. This makes sense as it’s just a variable substitution, where a = P, x = V, and y = I. Multiply both sides by x, and you just get P = V * I, which is correct for DC. I won’t get into AC power, as that’s a whole ‘nuther video! 😎

MIKE RON WHITE, Went to VEGAS 🤣🤣🤣🤣🤣🤣🤣. I watched this on a Sunday evening and I laughed for an hour. 🤣🤣🤣🤣🤣🤣🤣

Was this thing UL listed?

I'm glad i have never seen one here.

I was thinking they could be used alone.

that why I went Pyramid power supplies it safe and it SHORT-CIRCUIT PROTECTION mike

Arlen is a chump when Carl owned the company it was much better.

WOW!

Wow super ghetto. Absolutely amazing.

Actually, even if they did connect the hot wire to the chassis, they would cheap out and not use star washers and it wouldn’t make good contact! 🤣 And what’s up with the hand-made PCB inside. Looks like a bunch of capacitors and diodes. What comes to mind when you see a ladder of caps and diodes? That’s right, a Cockroft-Walton voltage multiplier. But it doesn’t look like they even did that correctly; it looks like a weird pi-network filter, but someone substituted diodes for resistors. WTF?!? Furthermore, they clearly had heat-shrink tubing; why not use it to insulate the “hot” mains connections on the fuse holder, and on the relay?? Give this to Wile-y-Coyote; this was made by the fictitious “Acme” corporation just for getting rid of pesky cartoon villains!

Good Video...But I know You meant inversely proportional.;o)

"I'm not going to plug it in". Good call, neither would I. Looks like scrap metal to me.

They also sell a 3500amp version for about $10k- oh my god

You could make that power cord Writhe like a snake.

The best thing you could do to this power supply is disconnect and cap off the mains inside before you return it.

Shit me not, the worst power I never built myself . I like their attempt at the soft starting using the dc supply to pull in the ac relay. I bet that’s why it had the large fuses in due to inrush and they couldn’ stop them blowing at the correct current rating. Still a very instructional video on how not to build a PSU. Ps I think the capacitor to the ac - dc ground may have been intentionally for RFI, but I don’t condone how and why they did it.

Hi Mike, I enjoy your videos and appreciate the time you take to educate those interested in electronics. However, I do want to correct one point. The fuse on the chassis of this device is for protection of the device itself, however inadequate it is in this case. It is not intended to protect the line cord. That function is reserved for the building branch circuit breaker or fuse. Since the cord is equipped with a 15 amp plug, it must be connected to a receptacle protected by a 15 amp circuit breaker. I fully agree that the cheap Chinese ps is junk, poorly designed and constructed and should not be used. However as a retired electrical engineer I just wanted to set this one issue straight. Protection of electrical circuits is always on the “ upstream” side in terms of current flow.

Is that really like 10 chinesium eBay smps’s paralleled up? My god son...

Arc welding - Good one lol

Maybe it is time to put this item through the re-cycler so it can be used for something much safer.

Is this thing UL approved ?

DISLIKE!! Too verbose and not much substance. Somewhere he might have mentioned the voltage, but who knows.

Back in the day when we built a Hi current power supply using 2N3055's we would use resisters to current limit each transistors output. I do not see that there. Oh and there is no way the bottom middle supplies are going to be able to keep cool. Why didn't they start with Meanwell MP1k0's. I also think if your planning to use a 1kW linear for your amateur radio shack buy one that's designed to operate on 120/240v, don't fall for this junk.

Those Meanwell clones are missing ic's, chokes, lower grade transistors that do not match the current rating of the device, lacking proper control/feedback regulation of switching and safety functions. They have less capacitance and have to use more copper wire and larger toroid to attempt to make up for missing components.

Warning: Death Star Power Supplies Are Standard Equipment Provided To State Penitentiary's For Electric Chair Use Only. Warning:

Shiny garbage, as a licensed Ham and avid CB'er I am sad to say splatter stations are actually worse now, then 30 years ago. I never volt anything, and i stack two Astron 70's to a Maxwell super capacitor if i need to supply power with a large amp draw. Were not all crazy Mike :D

There's a reason why Wizard Made stopped dealing with this X-force shite, anyone can see it's a confused mass of left over tangled electrics that don't agree with each other those fuses look like they'd have trouble lighting off a 0.49' model airplane engine.

OMG, quite a terrible PSU lol! Lovely video!

WOW
