HI! i'm kinda new here...but I really need some help here...

well I'm about to buy a radeon HD 4670 from Sapphire and a phenomII x3 710, but Idon't know if my PSU will deliver the power I need and I don't know if my mobo will get burned up!

these are my current system specs:

amd athlon x2 4050e (2.1 ghz 45w cpu)

4gb ddr2 800

250gb at 7200rpm sata (WD)

Asus m3a78-emh-hdmi (using on-board graphics ''radeon hd 3200" )

well and I've got a 300w PSU that came bundled with the case (that oem psu we all know...) these are the important specs:

2 12V rails, the first one is at 10A and the second one delivers up to 14A

I i've read is that the 4670 need a 400W with 18A 12V rails, and I don't know if my PSU will hold a 95w CPU and a HD4670 without burning my system up...need help..fast!

Nope. 24A is pretty low. Anyway, 300W is kinda low for a P II x3 and a 4670. You MAY be able to run it, but it won't be stable. I'd recommend a good branded one for 375+ W. Best thing is to get a Corsair VX450. You'll get your bang for the bucks.

It will probably be fine, as that is a very low power card.


That having been said, I would always recommend replacing a PSU like that with a good quality unit.

I second what cjl says,

I wouldnt think for one minuite that the card would give you a problem, i dont know the power requirements of the CPU but as you have 2 Rails it shouldnt be an issue.
Strongly agree with this though.
