The chinese power supplies

[Amstellodamois]

Have you guys seen some benchmarks done against reputable brands? Do they catch fire?

Here's a "platinum" to illustrate:

why not use server psu instead, much cheaper and reliable

OMG, please avoid this Chinese junk.

You are spending thousands on video cards and trying to save few hundred on psu.....

Why not save a few hundred if possible? Also your "few hundred" could be someones "few thousands"

I ordered three 1200W PSU, so I'm with you on that. But I wouldn't call the server PSUs "much cheaper" than these chinese ATX.

[Bimmber]

I`m using HP 1200w server power supplies +PICO. Its a server component, designed to run 27/4, made to last! Small, quite, cheap compared to ATX branded power supplies.

Considering that this PSU requires at least 180 volts, I would have to concur you are better off getting a server psu off of ebay for half the price.  I doubt this thing will burn your house down, but I doubt it comes with a warranty so its longevity can't be good.

yup like others have said,

HP Server PSU is the cheapest most reliable PSU for mining. You can get either the 750w gold or 1200w platinum psu depending on what you need with a break-out board to support anything.

What if you put 2 PSu's to your 7gpu rig, so they won't be "loaded" too much? Still cheaper option or?

[Amstellodamois]

I'm considering $ per watt, whichever way you put it (two small supplies, one big).
I'd be curious to know the power (in)efficiency of these compared to Corsair's and whatnot.

It's 230V in the civilized countries
