Ideal PSU?

[rpgfan]

I've had my rig for almost a year now and my video card has always hummed and squealed. It didn't make these sounds too loudly, I just thought it was normal. However, recently, when playing some 3D apps like Far Cry 2 and Crysis, it will sometimes completely freeze and the audio will slow down and then completely cut. The only way to exit is a hard reboot.

Here is my setup:

CPU: Intel Core 2 Quad Q9550 2.83 GHz
VIDEO: Nvidia GTX 280
RAM: 2 sticks of DDR2 2GB 1066 MHz
HDD: 500 GB HDD, nothing special
OPTICAL DRIVE: Super-multi drive
USB: One wireless dongle that is always plugged in

CURRENT PSU: This.

I was wondering if this was adequate, or if the video card/something else isn't getting enough power, if not, what should I replace it with?

I want a PSU to be comfortable, something that could take the video card/processor going at full speed (performance 3D apps).

Thanks in advance.

Corsair. It is a tier one ps, and frequently has the highest 12v rail ratings in amps. Get a 650 or 750w.

o1die's got good advice

a good 550-650w PSU from a good brand (corsair, seasonic, enermax, PC Power and Cooling/OCZ) is fine for single card computers

Agree with above. A good 550 watt PSU should put out at least 40 amps at 12 volts instead of the 30 amps the Diablotek produces.

A Corsair 400CX produces as much usable power as yours does. I don't know if replacing the PSU will solve your problem, but it certainly cannot hurt.

I agree with o1die
