Stay far away... read the reviews.

My advice on PSU's: If its not Enermax or Corsair don't buy it. Always remember a bad PSU can destroy your entire computer.

Add Fortron to that list.

Funny thing about newegg reviews. 1 of the 1 stars was from a guy who didn't even have the psu. 

I got 2 of them.

The reviews on newegg are so misleading most the time. Most of the 1 egg reviews are because the item was DOA, which the review system specifically says not to do when submitting a review. Also, the distribution of reviews is heavily skewed to 5/5 or 1/5, since the education system makes people think 2.5/5 is not average but failing.

To be more specific, there are 29 reviews for this on Newegg of which 3 are 1 star ratings and 1 is a 2 star.  The other 25 ratings or 86% of the ratings are 4star and above.

And as mentioned in my other post, 1 of the 1 star ratings was from a guy who didn't even buy this psu.  He simply had a bad experience w\ another similar psu and chose to post a worthless flame review on this item.  Another of the 1 stars was a DOA claim where the guy claimed it fried his motherboard... while scary, it would be more scary if it wasn't just 1 guy saying this.

That may be so, but PSU's are the single most important component in your PC in regards to reliability.

If a video card or CPU fails you just replace it. If a PSU fails, you will likely have to replace everything that was plugged into it (hell you may even have to replace your house in the worst case scenario).

Given that, I don't buy PSU's with less than near perfect ratings and/or a brand I fully trust for reliability.

Spreading personal experience. I have seen PSU's go up in flames and I have yet to see a videocard or CPU do the same.

Just trying to help people buy wisely. I recommend Enermax and Corsair because of my experience with them but there are certainly other good brands.

It's not FUD.  Though Enermax and Corsair are not the only good brands, for sure... but the PSU is definitely the most important part of your PC.  Skimp on anything but the PSU.  The PSU will usually last you through more than one PC and crappy PSU's can and will take hardware with them when they die.  Yes, I suppose they could catch fire as well, but I've not seen that happen.

I'm partial to Sparkle, Corsair and Antec myself, in that order.

I just had an antec go bad on me.  It did not damage any other components.  Was in use mostly 24/7 for 4 years.  Replaced it with a corsair.

I can say that Xion power supplies (do they even make them even more?) like to die, and attempt to take hardware with them. I had two of them years ago that came with cases. First one died within a few weeks. The second one, which also came with a case, took two hard drive with them. They melted a chip on the HDD control board. The PSU's were not being over strained to my knowledge.

I have had a Thermaltake for over three years, and it's been doing great.

Seasonic, Silverstone and Corsair make the best high-end power supplies. Not subjectively speaking; Specifications wise. Everything else is practically junk compared to the top-line 850-1000W+ PSU's of those companies.

Enermax has also top notch guts under the hood, though is a bit less known outside the US.

Nice site, they reviewed the 700w Cougar PSU: http://www.hardwaresecrets.com/article/Cougar-CMX-700-W-Power-Supply-Review/1317

"The main problem with this power supply is voltage regulation. Starting at 560 W, voltages got outside their allowed range, what can make your computer behave erratically. We tested two samples, and both presented the same problem. Therefore, we can’t recommend this unit."

And that's why you should spend the extra money on a real PSU instead of skimping out a few bucks & ruining the rest of your PC

how about now that it's $199 again?

I stand corrected. Price doesn't correlate with quality in PSU's.
There's a lot of expensive no-name crap out there.

enermax and corsair are way too expensive to justify. I am totally for getting a solid psu for your mining rig, but those are borderline ripoff.

I use the coolermaster silent pro certified that's half the cost and never had any problems with them.

i have a computer w\ a 600w coolermaster and if i hook up more than 1 gpu, it starts smelling like burning.

Of course brand is probably the best correlation with quality but interestingly so is weight.  So long as makers do not start purposefully adding weight (none I know of so far have) if you pick it up and it feels light.... its junk.

I have seen Xion and some other units and they are about 1/3 lighter then the good brand names and they do not last.

I had a psu start to smell like that when I put the 3rd card on it.... so I left it running to see how long it lasted. Well let's just say in a few hours I was getting my RMA #.

coolermaster has many different lines of psu some are pertty cheap. but i like their silent pro gold/bronze certified models, seems to be high quality and half the cost of corsair/enermax. Most review tests confirmed the voltages are stable under max load. Good enough for me...

Choosing between these two, I took the Corsair - the difference of 50W wasn't worth the extra cost for the CM.

Apart from the lackluster cable length and the way they have paired the main cables, the Unit from a very quick specs glance and a quick look on Johnny Guru it doesn't look like a bad company. There lower end units got pretty good scores and looking at the power rating on the 12v rails they look pretty solid.  ;) pretty good by imo
