650w or 750w power supply?

post #1 of 23
Thread Starter 
Hi overclock members !

So Im the new rookie here at the forum and to start of I want to ask something that is giving me a headache

So Im going to buy within 2 weeks new parts to get CrossfireX, the parts are:

- XFX HD6870 Dual Fan ( I already have a HD6870 )
- 2x Aerocool Shark Fan 14cm Blue Edition
- 1x Aerocool Shark Fan 12cm Blue Edition
- 30cm Sharkoon Dual CCFL Caselight
- ASUS Crosshair IV Formula
- Kingston ValueRAM 4 GB DDR3-1333 Kit ( Maybe, Not sure yet )

Im keeping my AMD Athlon II X4 640,

I sadly don't know wish power supply I should take , like is a 650w even strong enough to power the parts?

My pick:
- XFX 650W XXX Edition
- XFX PRO750W Core Edition

The give a summary:
Wish power supply should I take? and is a 650w even powerful enough to power the stuff im going to do?

Sorry if it's hard to understand, My english isn't that good... I think

The 650W is absolutely enough. AMD recommends a PSU that has a peak power capacity of 600W, but the 650W XFX unit you're looking at has a continuous power capacity of 650W while its peak is somewhere over 750W.

That specific 650W XFX unit is a solid choice as well!

well..what if you want to ..err..try a bigger cpu and overclock it? say umm..the bulldozer? ok..maybe not that..but say..an 1100t? you would need about an 800-850 watt psu..besides..with a bigger psu..it puts less strain on it..therefore it lasts longer..

Agreed. You'll be very happy with that 650w psu. It's a solid unit and made with seasonic internals iirc. Congrats on your crossfire and welcome to OCN !!

Even with the upgrades you're talking about here, the 650W XFX unit he is looking at will be more than enough.

Thanks for the warm welcome guys! Happy to be on the forum , So much better then others .

Well it seems I can rest now , No bulldozer of 1100T because my bugdet was for CrossfireX, plus my parent freaked about the price with a 1100T ( 550 euros ).

That XFX 650w is modular? I don't want to have a big ball of cables

And It will also besides my DVD rom have my DVD burner back in it?

Thanks again! Im really happy with the responds
