agp x1950 pro power reqs

[Inspector Jihad]

hello all, I have an Antec 400W psu with dual rails running 14 and 15 amps each.

I have an x2 4200+ and one HD and DVD-RW...should my psu be ok for the power hungry 1950?

The X1950pro by itself consumes 65w at load, that's roughly 5.5 amps.

You should be fine. The X1900 series was known for being power hungry, the X1950 was the exception due to its smaller die size.

The AGP version consumes slightly more power than the PCI-E version due to the bridge chip, but this isn't a significant amount.

Just make sure you dedicate one rail to the power on the card, leaving the other to power the rest of your stuff.

to be safe get 500 or 550 watts psu.

You should be okay.

Corsair VX450 would be decently cheap replacement option if for some reason the Antec can't do it.

Watts are not as relevant as amps.

Example, I have here a Thermaltake Purepower 560W PSU. It isn't the best, because it only has 22 amps on the 12V rail. And it's amps on the 12V rail that really matter for graphics cards, not watts.

Having said that, this PSU powers an overclocked A64 X2 (X2 4200 @ 2.6Ghz), 2 Gigs of RAM and a 512mb X1950 Pro PCI-E card. The thing is virtually silent when gaming, it clearly isn't having any difficulty powering this system. I'd hear quite distinctly if it did.

Because as stated above, an X1950 Pro only uses approximately 5.5 amps of the 12V rail, 66W if you want to talk in watts.


So to the OP, I'd give it a try, you'll probably find it will be fine. And if it isn't, N7's suggestion is also worth consideration.

Okay 500w works ok with my x1950 anyway
