Is my 650W PSU good enough for GTX 970 SLI?

[JWEM]

Hi,

I have a EVGA SuperNOVA NEX 650W 80+ Gold Certified Fully-Modular ATX Power Supply and I was wondering if it was capable of running 2 GTX 970s in SLI.

I have a:
- i5 4690K overclocked at 4.4GHz 1.15V
- EVGA GeForce GTX 970 4GB Superclocked ACX 2.0 Video Card with a slight overclock without increasing the stock voltage (+450 memory and +110 clock).

Ideally I would like to get another GTX 970 in the near future, but Im worried my PSU isn't high enough.

Many thanks in advance =]

it may be possible, but I would get at least a SuperNOVA G2 750 or 850w for SLI.

yes it will be fine the minimum psu requirements posted by nvidia is 500w and considering your psu it gold certified it is very reliable

this will absolutely work but for sli you should be looking at 850w (this is only for 970/980 because they are very efficient any other card in sli you need 100w plus psu)
