Hi, I'm in the proces of building fastest PC for my budget possible. I just bought a Palit gtx670 jetstream wich i put in SLi, second card i can buy next week. But my PSU has only 1 6+2pin and 6pin pcie connector. The card comes with one 2 molex to 6pin adapter, can my PSU handle these 2 in SLI? My PSU is a Enermax Liberty 620w, it does have SLI certified logo.
You need a better PSU for sure a 750 or more with sli cert your PSU would be pushed to hard All that nice hardware dont skimp on the PSU get a good one
I won't be overclocking them. I have to make due with this PSU sadly. Also can't the 680 run on a powerful 750w in sli? Cause i do know that Enermax makes very good and powerful PSU's.
Dangerous. I'd upgrade the psu. I already had difficulties with a 650W PSU and one 670GTX while overclocking my CPU.
Alright, i gues you guys know better. So i bought a Corsair CX750m modulair psu, will i be fine with this psu?
680 sli I've been running two 680 in sli no problem on a thermaltake 650w psu I don't overclock anything though.
Two things you should NEVER skimp on when building a system. The motherboard, this is vital for later upgrades, better support, its basically the mother of your PC so treat her well and splash a bit more cash on her. But mainly the PSU, without a doubt the most important component to your PC. This does not mean you should get something overpowered like a 1500W PSU that is just silly. Buy a decent Wattage, with high amps, and make sure its a reputable brand as well for warranty support and reliability. Go for something like a Silverstone or Corsair 800W just to be safe.
Just Upgreaded My psu I just upgraded my psu a couple days ago antcipating the launch of the titan But i had 0 issues on 650 psu sense last may till now
That PSU will be absolutely fine running that. Based on your system with 2x 670 in SLI. Minimum PSU Wattage: 421 W Recommended : 471w +3.3V +5V +12V 4.9 A 9.6 A 33.9 A
i agree a refrance 670 is 150w so 2 is 300w a 620w will be fine, just make sure you look at your 12v rail, if like my psu it can do 850w on the 12v side thats 70a 12v if you want to se the ampage use of anything devide the watage by the voltage, i used to have a 650 psu and used to use it with the 2 470s with no problems and there using 230w each
^ It's too late peeps, i had already bought it, it came with my new case today. I was expecting my case tomorrow, gues i got lucky. I can say, i'm happy i bought this PSU, i love what they did with the 6+2pin connectors. There are 2 connectors on one cable so it will also look nicer. Still if i had known my enermax 620w would be enough i had not bought it as i also need new keyboard and mouse.
