There are some things you don't take a chance on, and an unknown 800w $20 Chinese unit wouldn't be one I would test with my components. I guess whoever is brave enough to try it out, let us know how it goes for you. I doubt this units would be able to output anywhere near its stated wattage. It only comes with two PCIe power connections, so that is a red flag for a 800w unit.

I was in need of 2 cheap psu's and instead of buying a $30 white one, I went for this. It had to pass some tests to get a bronze rating, and reviews are not as bad as some of the Chinese (though ALL are made in China ) stuff I did look at for more, so I took the plunge.

There are different levels of things built in China. It's the knock-offs and fakes people have to watch out for. I mean the fake Samsung/Apple chargers on some sites all claim to have passed safety certification tests, even though that is fake as well.

Anyways, it's your choice to take a chance on these, however I strongly discourage anybody who reads this thread to take a chance on something that could fry their components. It's a very bad idea.

Here's even a post over at JonnyGuru where a user asks to send one of these units to him for testing purposes:

http://www.jonnyguru.com/forums/showthread.php?t=15643

In which JonnyGuru replied:

LOL! That is NOT a CWT built PSU.

I love how they use Corsair stylization on the labels and put it in an EVGA looking box. This has scam written all over it. LOLOLOL!!!

A pic a user included from a Slickdeals post on this brand's PSU (page 2 of the JonnyGuru link):

I kept reading the JonnyGuru link above, and later on Jonny ordered some of them to see what they are:

Page 5:

I started with the 1000W.

So the PSU does not do 1000W, even at room temperature.

But it didn't blow up either. It actually ran for a couple minutes and then shut down with a soft little "click". Cycled the power and reduced the load and tried again.

Seems that the 1000W can do 800W at room temperature fairly continuously. And at a decent 82% efficiency as well.

I'm going to open the unit up next.

Got that one too. That one's next.

Come to think of it, the 1000W could never do 1000W. The label says it can only do 876W on the +12V rail. It has DC to DC, so that's going to take power from the +12V. So if you load up the +12V, you can't load the +3.3V or +5V. If you load up the +3.3V and +5V, you can't load up the +12V.

Even if you add the -12V and +5VSB, you can't get 1000W.

Page 7:

Ok.. Results of the 1000W from the Chroma.....

+5VSB efficiency is HORRIBLE. 40 to 50% efficiency depending on load. That said, the ripple on the +5VSB is amazingly low (like < 10mV).

Hold up time failed miserably. < 10ms at 80% load. Of course, that was to be expected since the bulk caps are so small.

Voltage regulation is "ok".

Ripple noise suppression is quite good at < 20mV.

Efficiency is the biggest short coming. It's "almost" Bronze.

Funny. I don't see an 80 PLUS report on Plug Load Solutions.

Also, in order to get 80 PLUS, a PSU has to be able to run at 100% of its rated load. These units cannot.

Page 8:

Nope. No idea.

PCB-A is very clean, though. Definitely comes from a decent PCB-A house.

Next week I'll take it completely apart and look for issues like cold solder joints and see what the components look like.

I'll be following Jonny to see what he discovers with the build quality of these units over the next few weeks, but I think finding this info on these units will help people to make a educated decision about these units when you can get a known quality unit for $20 more.

So if anyone wants give these a shot for $20, there's enough known info for caveat emptor.

Well from what I read, it was kinda junk, but not fully and thats what I need, and who is to bitch about $20, HELL the cables are worth that, look and see what a set of cables would cost, and they cant be that bad just being cables

I do agree that junk ones, with horrible reviews are ones Id stay away from, but thi sone had some decent reviews, and Im not looking for the full 800 watts anyway, dont need that much for what I need them for, so instead of buying a cheap 500 watt and getting 300 real wats, I got a 800 with maybe around 6-650 watts, which is more then I need for $20 bones shipped.

Nothing wrong making a personal decision to try them out. I just wanted anybody who see this deal to have the information needed to make the decision themselves. From my experience, especially when it comes to power supplies, you get what you pay for. A person defintely does not need to spend $100 to get a good PSU, but high-wattage power supplies from unknown companies under $30 are always a thing a person should be very careful about.

Also, PSU cables between brands are NOT interchangeable (there is no standard). So DO NOT use these cables on another PSU or it could fry your components as well.

Sure they can. Use a cut rate connector and higher (thinner) wire gauge (thick insulation is cheaper than copper to make a wire look good, who strips their wires and checks whether the gauge marked on them is correct?) and they may burn up under load and melt the connector of whatever they're plugged into.

Who knows, maybe these are black market stolen off the back of a truck or an excessive % burst into flames during QC so they were chucked in a dumpster and that explains the low price, but otherwise, the first thing I'd rather have defeatured to lower price is no modular cabling.

It's also worth noting that none of the reviews are even 6 mos. old yet. Many generics will work for a year or more before Something Bad Happens.

Thats when I get them on and check votage and make my own if I have to

Yes you get what you pay for, but keep in mind they are on sale so should of cost more....

Got both units today. As far as "cheap" goes, these look not the part at all. Very classy presentation, weight, and looking! As for the only 2 6(8) pin cables, there are 2 of them, however each cable can supply 2 cards, so can to a total of 4 with it, if you dared to. For what I got them for, one low power solution, and my sons amd 8370 and gtx 970 more then happy. Both are VERY quiet, can hardly hear run, but do push our a fair amount of air, not even hot air at that. I felt I got my $20 shipped each was a great bargain. Does have 3 years warranty so, hope Ill never need it.

Damn, that wasn't your average apevia or raidmax "800W" and I missed it. They don't even list the 800w on Amazon now and for the pricing of the 1kw I'd prefer some gold rated 550 or 650 Seasonics.. Probably a clearance sale?

Well hopefully if they don't work out for you as much as you hope, the company will have a RMA center located in the U.S. to send them back to for replacement. Otherwise, shipping to China could be very expensive. I don't even see them listing power supplies under their product catalog:

Even if I get a year out of them, it gives me the chance to save up for a better one, I was just broke, and had these systems laying around till I could afford something better, but still at $20 a pop, last a year, Ill still be happy, they fit the bill for now to get them up and running again....

And again, the build quality feel, in unit and wires, and presentation, this didnt look like any other cheap psu Ive ever bought, and paid more then this for :O
