Trifire 7970's...1050w Enough?

post #1 of 65
Thread Starter 
Yep, the dilemna is in the title, I have a spare and don't want to buy another, if It's not enough, I'll snag a double wide case and a 300w PSU just for one of the cards. I'm using the same PSU in my current rig and have quite a bit of headroom for all the larger hardware I'll be equipping. Advice? Proposed rig is in my signature.

I think it might be pushing it, if it where me I would just buy a 1200w psu now, and sell the current one later to cut your losses.

Really?


OP, what are you going to be doing with them? gaming, or planning on maxing them all out on benchmarks or something like folding? It may be enough for gaming, but not if they are all going to be maxed.

no it is not, many will tell you it is though.

They are wrong

Your spending $ 1700.00 on GPU's buy something to push them

That's the general reaction. I've got dual right now and I get about 40fps with AA turned off. (eyefinity) The scaling at this point in time is miserable, but will get better as newer drivers come out. I want this rig to last me 4+ years, 2 of which I'd like @ max settings. Plus I have money, and lots of it.

it is well more than enough think about it,

max watts of each 7970 is 250w-275w
so 750w to 825w, And thats IF they get 100%'ed and oc'ed, which is highly impossible.
cpu will use ~107watts at 4.6ghz (according to my cpu-z and my i7 doing 4.6)
so ~932 MAX, fans+harddrives+mobo aren't much.

If it is the seasonic unit, i think it will be fine.

but then again, if you got the money for it, i think you should go for a 1200 unit as it isnt much of a price difference.

EDIT: I agree with WitchDoctor's recommendations, I would also second the Corsair AX1200 unit. Their Customer support is apparently amazing according to
everyone here.

If you have money then sell the 1050w and get a +1200W PSU. Then you can rest assured that you have enough power to OC thous cards and considering the OC potential you will be tempted to eke out every last Mzh. devil.gif
