im building my first PC and i was wondering if my 630w psu, http://pcpartpicker.com/part/rosewill-power-supply-rg630s12 can run my 770 http://www.newegg.com/Product/Product.aspx?Item=N82E16814127741&cm_re=gtx_770_msi-_-14-127-741-_-Product i know that it meets the requirements for the GPU, but is it enough so that it wont short circuit my motherboard?
EDIT: here is the link the the build that i will be using it in: http://pcpartpicker.com/user/TotalSandwich/saved/XZ6D4D
I would think you will be OK but if you have the money it can't hurt to go with a higher wattage.
Yes its More than plenty for a GTX 770. I currently have a Corsair RM650w with my 770, Normally the fans are supposed to spin when i'm pulling a high amount of wattage, i've never seen the fans on my PSU spin ever. except when i ran two R9-270xs in Crossfire.
Well i would say that's fine, its a little close though. Its never a bad idea to spend a few extra bucks to give yourself a little extra wiggle room.
I second Kat's answer. My backup rig has a RM750 and a GTX 770 and I have never seen the fans spin, ever, not even with a prime95 full blend test =O. You could realistically run a 770 on a 450w.
Here is a full Intel system with a 780Ti running on less than 450W:
So you've got loads of headroom. Obviously, efficiency matters, also.
you can even power a system with a 290x or 780Ti with 630W no problem lol ☺
I have that video bookmarked just for these situations
