Hey guys, i'm just building a new rig to replace my old computer, which will be mainly, if not entirely, for gaming.
After some research i have narrowed it down to using 2 GTX 470s in SLI, because to me it seemed the best performance for the money, and i wanted nVidia for PhysX (as opposed to getting a single 5970, or a 480, or either of these coupled in SLI / Xfire, which seem way too expensive for the performance, imo).
Now, the thing is, through some unimportant circumstances, i ended up with this power supply a few months ago: Sirtec HPC g14c 1200W. So i thought i can save some cash if i dont buy a new one, since i already have a 3 year warranty for this one. The question is, will it be enough for 2x GTX 470s in SLI? I have the required connectors, so that's not the problem; the problem is performance: will it be good enough?
Also, i was thinking a bit about future proofing and the possibility of buying a 3rd 470 for a 3 way SLI in the future. Is that too much for this PSU, should i just forget about it right now (assuming i keep this PSU)?
So, to sum it up:
1) will Sirtec HPC g14c 1200W be enough for a 2 way GTX 470 SLI?
2) if the answer to (1) is yes, can it also hold its own agains a 3 way SLI of the same video cards?
* Also, my pc will have a 960 i7 (cooled by Polimatech Megahalems), and one 2TB hard drive, all on an Asus Rampage iii extreme. I will attempt only mild OC to the CPU, to get my ram to run at 1600 MHz. This is to give you guys an idea of what else will need power.
