View Full Version : 4670 really require 26 amps on 12V?

Just got an ASUS EAH4670 for my daughter's PC. Her PC just has an old school 300W Power Man power supply from my old Slot A Athlon 650Mhz system. The 12V reads 11 amps on the sticker.

I'm running only a hard drive, DVD, 2.5GB RAM, and a 2.6ghz Athlon 64 at the moment.

To complicate things, I just got an Athlon 7750 X2 CPU (95W TDP) for the same system, although I haven't installed that yet, either.

How does the amps thing figure into all this? the ASUS box says I need 25amps on the 12V line. Is that just a disclaimer or something or do I really need 25 amps? I was under the impression that this card sips electric.

25amps is for the whole thing, its not just for the video card.. sounds like the psu you have is 5v rail heavy and a older psu design. it really is time for something new..

atm this is a really go deal

Well, it doesn't take a lot of power... I think it's specced somewhere around 60W max, which is about 5 amps. The 25 amp recommendation is to account for all possible system configurations, all sorts of quality levels of PSUs, and stuff like that. (A cheapy PSU may not actually put out 25A, even if it says it will.)

However... regardless of what the 4670 requires, I wouldn't use such an old PSU with a modern machine. It was decent quality when it was new, but that's about 10 years ago. The ATX spec has been updated a couple times since then, not to mention the capacitors in that thing have probably degraded quite a bit.
