Hi guys,

Will be getting a second GTX 670 to SLI.

Current system specs in sig - Will my PSU support another 670, and will this setup likely reach a bottleneck?

Thanks for looking.
 
Hey, would my PSU be enough to support SLI GTX 580?

Dont want to hijack thread, but seeing as its my first time SLI too thought there would be no point in creating a 2nd thread.

Thanks

If that's the gold rated version which i assume it is then yes easily.

For the thread starter: get a nice 850w gold rated psu or above so you can then upgrade your cards in the future if need be.

Yea it is the Gold rated version. Thank you very much for your help :)
 
Are you guys for real?

@OP your PSU is either a Seasonic or Channel Well (They both make TX650's) but either way it will be fine for SLi GTX670, hell putting your specs into a calc gives minimum 400w required with 450w recommended. Future proofing is all good but no point upgrading the PSU needlessly.

True but if you see like a good psu for £100 then another of the same model series £10 more that's 100-200w more surely you would pay the extra £10 for more future proof?:p

I was running an i5 3570k with sli gtx 670's, cpu @ 4.5ghz on 1.3200 vcore. Spec in sig with 1 ssd, 1 hdd, an asus xonar DX audio card and 9 case fans. Power draw at the wall on my 4 plug monitoring unit was showing at 430w when running heaven 4. Thats with the 24" lcd plugged into the power monitor as well.

Bottleneck wise, yes i did find the 3570k to be a bit of a bottleneck. Particularly in bf3. Card usage never got much higher than 80%, swapped over to a 3770k and even at stock im seeing 91% usage per card. Should be higher once i oc the cpu.
 
Woah, hold on a minute guys, your advice here is not very good.

Like setter above, I ran SLI 680s with an overclocked i5 2500k @ 4.5 GHz and power was about 450W from the wall in total for the whole machine.

You'll be fine unless you're going to push your CPU and GPUs to the extreme at the same time. If you're just gaming then 650W is ample.
 
i love it when people talk about future proofing.. generally speaking, pc hardware is getting more efficient, as such if anything the power requirements will go down.

having said that, i ran my gtx690 and highly overclocked i7 on a tx 750 with no problems. i did upgrade because of some coil whine i was having, with the 1050w i have peace of mind, but it hasnt made any difference in real terms. i also like that it is a gold certified psu rather than bronze, also modular. so tertiary benefits if you will..
 
Efficiency of new components is indeed very impressive. Prior to the spec in sig i was running an i7 920 @4.2ghz, coupled with x2 gtx 470's oc'd to 750mhz core. Same other basic components as mentioned above. Power draw for that rig running games was 630w at the wall. 740w with furmark, 860w and climbing running p95 small fft and furmark extreme burn simultaneously, (not something i want to repeat).
