PSU advice

[ElFenix]

Ok,Would you mind recommending a few more psu/s that may be on newegg that fit what I want to do with the gear I have....

Something that won't break the bank, won't blow my system, and will last for over a few years running? (Yes, I know this is probably a ridiculous request)

I am sure I will have my computer on 12 hours a day. Will I be editing, gaming, or doing 3d work that whole time? Definitely not....Most of it will be simple regular computer work....

I have gone from 750W to a 500W now? I wonder if I am hindering myself by not ever considering to use SLI or crossfire?

thanks again

any of the 75ish and under PSUs from lehtv's first response will work fine:

XFX 650W $55 after rebate <-- has 4 PCIe connectors so in theory it will handle 560 Ti SLI or 6950 Crossfire provided you don't OC them too much
XFX 750W $60 AR today, $75 AR normally
Corsair TX650 V2 $70 AR
