SO very simple question corsair ax850 watt or coolermaster 1000w silent pro- both 180$ can't make up my mind love corsair but is the extra 250 watts gonna show spec ------- i5-2500k msi z68a gd80 g3 corsair vengeance 8gb gtx 465 (Overclocked to the max by me) thinking of upgrading video card with 600 series in an sli 1 hdd 1 blu ray drive
1) The Coolermaster is an inferior psu 2) 1000w is overkill for SLI , 850w will do it's the voltage on the 12v rails that counts more.
i'd have to back R29K on this. Corsair PSU has the best Price/QUALITY/Performance Ratio on the market, at this moment, corsair PSU is the only PSU i recommend to my customers. Thats after owning 4 of them myself, running and well.
I belive its not so much the voltage, but the current, on the 12v rail. ( Power=Current x voltage ) I've been running a pair of 4890's for quite some time now with a Corsair ax850 and have never had an issue with it. Get the Corsair.
