I am just not that sure about the coolermaster 460W Real Power Pro (the one to go for rather than extreme power) or VX450 Corsair. What is the maximum power that can be consumed on the rig ?
Let's say what would be the total power draw for all the components
Processor (OC'ed)
Motherboard + RAM
GPU (Oc'ed)
HDD ( 1 or more , depending on disk capacity)
Optical drive under load (DVD burning process / Continuous data transfer)
Cabinet fans
let's say Tech_wiz has a system suggested in here with either the real power pro or vx450, what would be total load on the PSU ? Its better to have some headroom for more juice, just in case. As techalomaniac suggested, a 650W PSU would be really the most one can need, even if you have dual GPU's and loads of HDD's.
I know im being paranoid by including the fans and optical drive
