[PSU] Suggestion of New PSU for my System

Hello I purchased a new video card online this morning, however I also require a new Power Supply to run my computer efficiently once I install the new part. I have a general understanding how computers work, and don't know much about certain things like PSU's and what their stats means.

My new card requires the following:
450Watt or greater power supply with 30Amps on 12 volt with 2x4 power connector recommanded.

My system specs are:
P4 3.0Ghz
3GB DDR Ram
512mb ati hd3850(new video card)
2 DVDR/DVDRW/CDR/CDRW Combo Drives
2 HDD's IDE 7200rpm
2 USB's connected


This is my current power supply:

The Video Card says 450Watt required, but when a run a Wattage Calculator it says I only require 300Watts (with this same video card), but I understand that the biggest thing to worry about here is how well the PSU can handle under load, in which I'm assuming (don't really know) that it cannot.

What do you suggest is a good PSU that can handle the power required by this video card and is relatively cheap.

^+1. If on a really tight budget the Corsair 400CX would do.

+1 for the CX 400...It can easily handle 4850 (Mayb even 4870)

But if u are planning to change ur setup and card any time soon, then going with the Corsair 550 makes sense...

thank you, I appreciate everyone's input, and have decided to go the VX550. Seems decent and allows room for minor upgrades if need be.

Yes.
