What would be a good power supply for 2x r9 290 and 4x r9 290?

post #1 of 8
Thread Starter 
Hey guys, I have 2 computers that will be needing a new power supply. One computer with just 2 R9 290 and the other with 4 R9 290. Both will be overclocked to as high as they can.

The 1st computer will be the one with 2 R9 290 and the specs are:

- i5 3570k (Will be heavily overclocked also)
- Asus P8Z77-V PRO
- 2X Sapphire R9 290
- Corsair H100i (with 4 Corsair fans on push/pull)
- Samsung 840 Pro 256gb SSD
- Samsung F3 1TB
- 4 gelid fans
- Samsung ECO green 8gb ram


The 2nd computer will be running 24/7 with 4 R9 290 and the specs are:

- 2X Sapphire R9 290
- 2X XFX R9 290
- ASRock FM2A85X Extreme6
- AMD A6 6400K
- Corsair Vengeance 4gb
- Sandisk 32gb SSD


For the 1st computer, I was thinking about getting a SeaSonic X850 850w power supply but, I think that would be slightly over kill?

Also, for the 2nd computer, I was thinking about getting a Lepa G series G1600 1600w power supply.

For the 1st rig, i wouldn't be too comfortable with 800W of power as This test show just how much of a power hog the 290 really is. I'd recommend this. Enough power to run the 290's as well as the processors overclocked to the sky along with accessories.

On the 2nd rig, may i ask why would you wanna pair it up with a A6 6400K processor, as believe that processor would bottleneck the cards.

For the first system with two video cards this is too good a deal to say no to

For the second system with four video cards something like the EVGA SuperNova G2 1300 watts is what i would look at

you should provide alittle more info on what this machine will be doing. are you going to be folding(or something similar) on this machine 24/7? alittle more info on the application would help in deciding which PSU/efficiency range you should get. also are we assuming you have sufficent cooling for the system? also not too sure why you are going with an A6 since an i3 will likely be a better choice.

The 2nd rig will be mining for digital coins.
