980 SLI questions

[bradUK]

Hi guys,

So, spec as sig;

Is a SLI bridge cable required? I've seen posts that say they "talk" via the pcie lanes and some saying the bridge is still needed.

Also, my GS600. I realise the recommended PSU supply rating for SLI'ing these cards is higher but, would I cope on standard clocks in the mean time? I've been googling and there seems to be a few people running the cards on 600w PSU's. It would just be a stop gap for a few weeks until I get a new SuperFlower PSU.

Cheers chappies.

An sli bridge is required. Its only newer AMD cards where no type of bridge is required

4770K @4.6
8X 120mm case fans (all running off PSU)
2x HD, 2x SSD



Just did this one Pc has changed a little since above but still running
about the same watts

4970k @4.6
3x 120mm 6x140mm (all running of PSU)

Thanks bud, I think I'll be okay for the meantime on my PSU in "real world" use? Loving the 980 so far!

Personally i wouldnt risk 980 sli on a 600w psu. Im running 780 sli on a 1000w superflower, now the most ive seen used power wise is 620w at the wall playing bf4. Thats with cards at stock but a 4.7ghz 1.300v oc on the cpu. I wouldnt reccomend doing this on a cheap psu.
