280GTX Power Problems

chunky1311 · 12-10-2008, 01:28 AM

Heey,

I got a new GTX280 today, i put it in and booted up.
Installed its drivers and reset the computer.
Everything goes fine until i run a game.
When i open a game, my PSU makes a loud buzzing noise.
Sometimes high pitched, sometimes not so.
If i listen carefully, it sounds a little bit like a sparking kind of noise.
I have a Codegen 650W ATX 12V power supply.
It should be enough to power the 280 shouldn't it?

Before i upgraded to the 280 i had a 9800GTX.
What's causing the buzzing and how can i stop it?
It doesn't sound safe so I'm scared to play games

Can someone help me out?

I'll put the sound it makes up on YouTube if that would help?

Any assistance would be greatly appreciated!

P.S. My PSU has two +12v rails, one with 17amps and the other with 18amps.
The gtx280 needs 40amps... so would this be whats causing the buzz/hissing sound?

Sounds like your PSU is inadequate for sure. The gtx280 is a monster, gotta feed it some good power. I'm sure you'll hear it over and over, but wattage isn't the most important thing. Here's an example of a 650W PSU that would be better suited for your rig at a reasonable price: Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Power Supplies

I believe it has 52A on a single 12V rail.

The buzzing may be from the fan on the video card. I've been kinda busy lately, so I haven't read up on them, but that would be my first guess.

Codgen isn't one of your better PSU companies out there. While the 40A would be for the system with the video card, that doesn't negate what a crap PSU is going to do.
