EVGA GTX970 (SLI) Power Consumption?

Hardware Hub GPU
21

You should be fine with 750w. It's what I have and zero issues.

22

Thank you for the help!

Am going to grab another GTX970 (because it is on sale right now), and will grab the Corsair RM850 at the end of the month.

Thanks again!

750W isn't the issue, CX is. If you have a CX you are running a risk.

I have a CX and it's been perfect for three and a half years.

True enough if they ALL had bad caps there would be a product recall whereas in reality apparently a smaller but significant amount have been known to exhibit negative properties on high load.
I personally would err on the side of caution with a PSU.

Hello!

Thank you for all of the helpful replies!

I am upgrading/replacing my PSU, due to (1) the chances of this CX750M dying on me and taking something else with it, and (2), with the setup I will have when the second GPU is installed, a 750W PSU would be running at a fairly high load. I would prefer to keep it below 70% and with a 750W PSU, I am not 100% sure that I can keep the load under 70% in-game.

I have started having issues with this PSU randomly cutting out over the last month, so have been looking at replacing it anyways.

The new PSU is going to be a Corsair RM850, 850W (obviously).

I have no plans of overclocking these GPU's or my CPU. If I plan to do so, I will do some serious upgrades to the CPU cooler and possibly another mobo. The current CPU cooler is a Cooler Master Hyper 212 EVO, however, should I choose to overclock my CPU, I will installing a water cooling unit.

Thanks again for all your help!

750 is enough.

29

I am aware that it is enough, however, I am replacing the PSU. Having enough power, and a good size power buffer, allows me to, in future, upgrade my system more without having to worry about power issues.

Ah sorry I should have read better. I've replied to a lot of SLI power supply things lately so I have gotten into a routine of saying the same thing

31

Not a problem! I completely understand, operating 14 servers gets confusing quite often.

That is not what I use this PC for, I am a server operator, I only own 2 of them, which is enough. I keep getting asked if I can/will be head of servers.

Thanks again for all the responses!
