GTX 970 SLi - What PSU?
So here's my predicament, I began to slowly gather parts for my build and so far I have:

CPU: 4790K
RAM: 16Gb(2133)
MoBo: AsRock Extreme6 Z97
HDD: 1Tb WD Black Caviar
SSD: SanDisk Extreme II 240GB
PSU: Seasonic SS660XP2 - 660W

I didn't buy a GPU 'cause I wanted to wait and see what this new series from Nvidia would be like and sure enough, I like what I see. Especially the GTX 970 since I can buy one now and save money to buy another down the track and try my hand at SLi.

On top of what I have listed it will also have the regular stuff like blu ray player, case fans and etc and I hope to add a decent CPU cooler at some stage too but I have no idea if the PSU I bought will be able to take it all.

Is this a case of rookie mistake or beginner's luck? Should I return the PSU and go for the 760W instead?

I know it's early days on that GPU but I'll appreciate any input you may have!

Thank you!

One of the reasons people love the lower power/heat of the 970/980 is the room for overclocking, if you're gonna run it stock you're missing out, but if you are gonna take advantage of the O.C. headroom of these cards you're gonna need to get more wattage to run it. Even a little more than recommended because the standard numbers are non-O.C. Which in my mind defeats the purpose of the 970 in the first place.

One more question. Would I need any cooler system? Or would the fan that comes with it be enough.

Well as EVGA not available to my location , i did purchase Seasonic Platinum 860w and i can tell its really bad ass , so you can try seasonic's 760W Platinum for your 970 SLI , i guess that will be more than enough :)

Im wanting to build my own system I have my eye on the gtx 970 paired with the i5 4690k on the Asus B85M-E CSM
I dont really see a need,at least for a while, to run 2 cards right now with that in mind should a 600w be enough? I plan on makeing it a steam machine and a few other games such as skyrim and assassins creed. Other question is what cooler would be sufficient?


600W is plenty if you plan on using one GPU, it will easily be ok for a 970 and that I5, with enough left over for a bit of an overclock

People are saying 850w is enough, I have a 800w. Is that ok? It's by Corsair, a very reliable company, it's been a great CPU so far, but I need SLI 970s!!!


Saying that it is by Corsair doesn't make it reliable.They have good and bad PSU's in their line up.
