I have a three year old Gateway 420GR (all original hardware, never upgraded). I'm replacing a hard drive that recently died so I figured I might as well swap in a new power supply as well (the old one has been touch and go). The specific replacement part Gateway recommends costs $99.00, but I see power supplies for half that price at newegg.

Here are the specs on the official "sanctioned" PS:

Any recommendations for a cheaper brand that would be 100% compatible with my existing machine?

That Thermaltake is probably a great choice for your system. Depending on your budget, Corsair makes a great PSU also. This one is twice the price of the Thermaltake, but it should be more efficient and has a higher Amp 12v rail, so might be more stable. I don't know what other components are in your old Gateway, but it might be worth it to think of this one as well.

Good luck!

GMTA. I was just about to suggest the 450VX to the OP.

zombiewhacker: call or email Gateway asking if they use a standard or proprietary PSU in the 420GR. You will need the serial number at this time.

(I suspect it's a standard Bestec 300W, which fail frequently.)

garmanma's Thermaltake recommendation for a simple replacement or the Corsair if a gaming quality video card upgrade is planned.

Just stay away from cheapo psu's like the Bestec...they have a reputation of killing motherboards and other components when they die.

The power supply is the single most important part in your machine; these are both good recommendations.

Sorry for bumping/resurrecting an old topic but I'm in the same boat as the O.P. I just received a PNY Nvidia GeForce GT 220 for Christmas but my original PSU is only ~300W and the card requires at least 350W.
I don't know a thing about installing/replacing PSU's. Would the Thermaltake and Corsair PSU's fit for the Gateway 420GR?

Shouldn't be a problem! I love my Corsair... and I've also had great luck with the Thermaltakes... Corsair is in my personal computer, while Thermaltake is what I use most often in other builds. Good luck!
