Recommended PSU wattage for GTX 960 in SLI?

bmndan · Jul 9, 2017

Hi, I was wondering what is the recommended PSU wattage for two GTX 960 4GB in SLI?

My build:
CPU i7 4770k
MB Gigabyte Z97X-UD5H-BK
RAM 32GB @ 2400MHz
SSD 1TB x2
PSU Corsair CX 550M
CPU Fan CoolerMaster Hyper TX3 EVO
Case Fan Corsair AF120 x1
(no GPU, just the buit-in Intel HD 4600 from the CPU)

If you don't have a GPU then buy a single stronger GPU than sli 2 weaker cards. Sli has drawbacks including not all games support it and of those that do some don't support it well.

This shows up to 170w on 1 version of the 960 http://www.tomshardware.com/reviews/nvidia-geforce-gtx-960,4038-8.html

So 340w plus 150w for everything else. That would be really pushing a 550w more than I would be happy with, really a 650w or greater to have a decent amount of headroom. Running a psu near max is not a good idea.

Keep your current CX550M PSU, then, just get a used GTX 970 (or if prices of the GTX 1060 goes down). That would perform much better (and less expensive) than getting 2x GTX 960's.

They're more like 120w GPU's, I have two of them and neither draw 170w.

As you can see from the link it depends on the version. However its a mute point, unless they are ridiculously cheap a single card is the way to go.

It's up to the OP whether it's a moot point or not and on average they are still 120w cards.

As we don't know specific model its safer to look at worst case than assume average. I provided a link the OP can review.
