I'm in the USA. The system I've designed costs $1125 or, about, 700 pounds. I made it kinda in between the February 2011 buying guides Enthusiast overclocker and Gaming workhorse with, of course, my own input. They used a 650 watt power supply on both but online calculators (which aren't perfect) say I need at least 750 watts. I might upgrade some components. So how much power do I need? 650-750? Any build suggestions? Here's the system: COOLER MASTER HAF 912 ATX midtower case ASUS Black 24X 2MB Cache SATA 24X DVD Burner Antec EarthWatts EA750 750W (Should I instead go for a 650 watt? ) Intel Core i5-2500K Desktop Processor Asus SABERTOOTH P67 motherboard (All reviews I've read say the cover does work some. I can always take it off. Want a bit-tech review of it. Has yet to come out anyway.) MSI Hawk GeForce GTX 460 (factory overclocked to 1GB) A-DATA Gaming Series 4GB DDR3 1600 Desktop Memory Western Digital Caviar Black 500GB 7200 RPM 32MB 6.0Gb/s Internal Hard drive Widows 7 home premium oem 64 bit Scythe "KAZE Q" Fan Controller COOLER MASTER Intel GeminII S (motherboard does best with a top down cooler) COOLER MASTER Megaflow 200 200mm (2 of them for haf 912)
