Whats the W per 290 ? (250w)
i dont see were is the problem

290s are 300w cards, at least at stock volts / clocks.
No one was talking about stock settings.

1200w will be the safe , if you want to run without any troubles.

I got 3 x 290 Sapphire a lil bit overclocked...normal power not undervolt with a BeQuite 850w !
Seems fine so far working nonstop no problems at all

Platinum efficiency

That was when setting up the rig... now its kinda lil bit overclocked... dat psu seems rock
I had no doubt to be honest... its Seasonic parts into Bequite brand



Man, I'd get a 850w, at least gold, but damn, they're ALL sold out here and I can get a 1000w gold here cheaper than a 850w on ebay... so yea...

may be took the wron topic, but i did some tests on it:

how do you do cooling? airflow? i assume its not a good idea to use a 1000W power supply. Propose a 1200W.

Greetings
Thanks, but after further research I came to the conclusion that even a 850w will be enough (but they're all sold out lol!). So I'll be buying a 1000w after all.

As the title implies: Will be able to power 3x r9 290 with a single 1000w PSU? I can get this Tesla R2 1000W for rather cheap.

Yes it should work, but don't overclock too much cause it would draw even more power...

Oh I won't. Trying to be as cost efficient as possible with the KH / w ratio.
