Psu help !

hi here is my planned rig

last thing to be purchased is a psu (confused with all the options )

was looking at 1000 psu but my boss advised it was overkill + suggested an 850 would suffice

i would prefer modular becaus im OCD about cable management lol


core i7 920 do stepping (will be oc'd to 3.8 - 4ghz)
either gtx 275 or 285
12gb ocz titanium ddr3 7-7-7-24
gigabyte extreme x58
2x 640 gb sata HDD
1x 500gb sata HDD
TRUE 120 black (with dual 120mm 124cfm fans)
haf 932 (3 x 230mm fans + 1x 140mm fan (all standard fans)
1 dvd burner (prob pioneer sata)


thanks a lot for any help

^5 +1 what theAnimal said.

A high quality, high performance power supply in the 500 to 550 watt range can easily handle an overclocked quad core cpu and any single video card made.

It would be different if you were going to use mutiple video cards in SLI or CrossFire mode.

+1 for theAnimal regards the video card. Go for 275. If is for gaming even 3 gb is more than enough but buy 6 gb to be future proof.
I suggest that you will buy a psu bigger than 650W in case you will want to have SLI and have room for future upgrades.
