Question about power consumption

[mgray683]

I recently bought a new power supply ( http://www.newegg.com/Product/Product.aspx?Item=N82E16817713004 ) with enough power to handle my graphics card. I got it set up and powered on only to find that it isn't supplying enough power to the cpu. The old power supply supplies 36a to the 3v rail while the new one supplies 28a. If I plug the old one in it works just fine. I'm using a core 2 duo e7200. Is this an issue of a defective power supply or did I just **** up?

Well at 28a your talking about 92W for the 3.3v while 36a is about 118W. That really should be enough to boot up your E7200, altho running it stably is another matter. This kind of cheap power supply is often defective though so I'd RMA it and get something else.

2nd'ed. Return it for Corsair 450W. What's your gpu?

Thanks. Gpu is radeon x1900 xt. Will 450w be enough?

Yup.

450-Watt power supply or greater, 30 Amps on 12 volt rail recommended (assumes fully loaded system)
PCI Express compliant power supply (recommended). Connect directly to the power supply with a 6 pin PCI Express power connector
For CrossFire: 550 watt power supply or greater, 38 Amps on 12 volt rail
