Is there ANY decent SLI/Crossfire configuration possible on 650W?

[Jupiter]

Basically I have an Antec Truepower New 650W and I am in the process of buying a new GPU/GPUs. I have thought about getting dual gpus but have always known my psu would be feeble for it.

Is if there is any dual gpu configuration that would be worthwhile given my psu? For example a couple of R9 270s or something.

Thanks

There are but wouldnt you be better off overall performance wise with a single card?

290p is what i would get. Your PSU would handle the card fine and leave a little bit of headroom.

My 690 runs off a 650watt

Why buy two GPU's while you can get just a single one? Get a 780 or similar and then when you want to upgrade toss another one in - One, more powerful card is better than two less powerful one's imo

I wouldn't bother, just get a 780/290.

Any 170 TDP card setup will run off it, like double 670's or 760's. And they will match or beat a 290x/Titan (Not 780ti).

Two GTX 770's should be fine as long you no overclock them or the cpu to much..


Example
i5-3570K cpu = 77watts
x2 GTX 770 = 460watts (They Rated at 230watt each)
Total = 537watts

Which leaves you with 113watts for running the rest of your system..

But I would recommend buying a single GTX 780 or 780ti over two slower cards..

I have 2 HD7950's running from a 600W psu, although i think its over spec'd, since there is 4 12V rails each at 18A.

[email protected], 780ti SLI, 2xHD, 2xSSD, 8x140mm fans (full rpm) max was 630watts running Heaven extreme settings. 780ti's were at stock though.
