I am trying to determine if I need to get a better PSU and I can not seem to find the specs for the Corsair H50 Water cooling unit. I want to make sure my PSU is large enough to not cause any problems. I've looked around at PSU Calcs but none seem to list the H50. Here is my new system: Mobo: ASUS P7P55D-E PRO CPU: i7 860 Mem: OCZ Gold DDR3 1600 VC: ATI Radeon 5870 PSU: OCZ 650watt SDD: Intel X25-M G2 HDD: 320GB@5200 & 500GB Western Digital Green Cooling: Corsair H50 Fans: 2x80mm, 4x120mm Fan controller: NZXT Sentry 2 Drives: DVD-RW (1) Can anyone tell me if 650w is enough for this system? Thanks in advance.
