Corsair HX-450 enough for this setup?

Hi everyone,

I have recently purchased the following setup:

Antec Mini P180
Gigabyte GA-P55M-UD4 Motherboard
Intel Core i7 860
Corsair 8GB (4x2GB) DDR3
WD 250 GB HDD
Cooler Master Hyper TX3
Corsair HX-450 Power Supply
Samsung SH-S223B DVDRW OEM
Gainward GeForce 9400GT 512MB HDMI

I now wish to replace the video card with an ATI 4890 and install a PCIe soundcard as well. I may well add another HDD in the future.

So, I was wondering if the 450 PSU would be good to handle the additions to the setup?

It will handle your new hardware. I have a Core i7 920 @ 3.8GHz and an overclocked Radeon 4890 that takes about 430W AC extreme load (Furmark + Prime95). Taking the PSU efficiency into consideration, the computer's only pulling about 355W DC. Since your computer should pull much less, you'll be more than fine. I would imagine the fan would ramp up during load, however...

Thanks for your comment tehfire. Are you happy with the 4890 overall?
