Hello everyone.

I was just wondering if my OCZ 700W PSU can run a pair of GTX460's..I ask because i have an i7 950 running @4.0GHZ, 6GB 1600MHZ ram @1144MHZ, with an ASUS Rampage Gene 3 motherboard, and one 460 for now...I dont have any problems whatsoever with one card, but since my CPU is overclocked, im having doubts that 700W is enough..and IF it IS enough to run in SLI, will that effect the longevity of my PSU? (My understanding is that running a PSU near its maximum capacity, shortens its lifespan, and increases the chance of failure-which can fry other parts of the pc).

Your PSU has 1x6pin and 1x6+2pin connectors. You need 2x6pin connectors for a 460. 4x6pin for 2 460s. I think you can use a molex connector to solve that problem. 460s in SLi are recommended a 600W power supply. Your PSU is more than enough. Your system will not use the maximum amount of power it can use ALL the time, only when it is needed (rarely)... You will be safe.

460s in SLi will be sweet, good luck with your upgrade :)

He already has a 700W PSU, why would he need to buy another 650W PSU? :D

thnx for the quick reply, but im concerned that my CPU is so heavily overclocked. I know it draws a lot more power..anyone have any ideas what wattage 4.0GHZ i7 950 consumes?

thnx for letting me know..yea i checked out guru3d review on gtx 460 sli 786mb version, and their power consumption for 460 in sli was 433W(id round that off to 450, and 200W-worst case scenario, for the CPU) so im in the 650W zone..i just hope this OCZ StealXTream 2 700W doesnt die on me due to running near its maximum, because i use the pc mostly for gaming....well gotta save up some cash, and in the new year ill grab another 460...right now after rebate, their 150$ from tigerdirect.ca!
