650Watt PSU Enough for SLI?

[ATLASINCARNATE]

What's up guys, so I recently put together a gaming rig, and with a 1440p monitor I've had my eye on for quite some time coming out soon, I may add another EVGA SSC GTX 970 to my build. However.. Would it be a bad idea with my PSU? Should I upgrade before getting another card? Also, I haven't done any overclocking and don't plan on doing so.

 

My Build:

 

CPU: i5 4690k

CPU Cooler: CoolerMaster Hyper 212 Evo

GPU: Evga SSC GTX 970

PSU: Evga SuperNOVA 650W 80 Plus Gold Certified

SSD: HyperX 3k 120gb

HDD: WD Blue 1TB Drive 

Motherboard: Asus Z97-A ATX LGA 1150

Ram: Gskill Ripjaws 2 x 4GB DDR3 Sticks 

 

On PC Part Picker with two cards in my system, it's estimated the wattage will be around 492W. Let me know what you guys think.. Thanks.

With that PSU, yes.

Yes it will maxwell gpu use very little power.

At stock speeds yes it will be fine... but that PSU isn't very great in terms of electrical performance, should have asked about it before purchasing.

At stock. Not much headroom for overclocking though.

Pay little to no attention to the power needs that are declared by PCPartPicker. Even if it is overkill, it is best to look up your GPU on the manufacturers website and choose a PSU that is a bit over that wattage. Better safe then dead from electronic smoke inhalation.

It should be enough, yes. Check here to be sure: http://www.extreme.outervision.com/psucalculatorlite.jsp

Uses about the same as HD 7970/R9 280X. But 650 is enough for 2x 7970s anyways

 

 

 

 

2x HD 7970s peak at ~625W at the wall.

I think you'll be able to squeeze it in but if you wanted to future-proof your build I would say upgrade it.

[hak4fun]

a 650watt should be fine. But it wouldn't hurt to upgrade to something like a 750-850watt. would leave abit more headroom.

I have a very similar build (I5 4570s) and am wondering can I sli 2 780's with a 650W psu?

[Ian Schmid]

i think you should get like a 750 wat because it will defernetly be enoght and it gives you overclocking ability

[vexea]

With two 970's that power supply is perfect, Nvidia has really out done them selves in the power efficiency race. 

 

P.S. is the last 50 watts of your power supply less efficient?...(970 Joke)

[DarkRift5]

You should be good, as long as you don't do ridiculous overclocking on the CPU and GPUs.

780s draw much more power than 970s if I recall correctly, I think even 750W is cutting it close.

[GodSpoon]

Long story short, your doing a maxwell SLI with two 970's

Yep, should work great
