I want to update my video card, but I am not sure whether my existing power supply matches the video card or not.

The video card I want is: BFG Tech BFGR76256GTOCE GeForce 7600GT 256MB 128-bit GDDR3 PCI Express x16 Video Card, from Newegg.com

According to the website, a 350W PCI Express compliant system power supply (with 12V current rating of 20A or more) is required.

Here is my existing power supply: +12V current rating is 22A, but the max output is 305W. (This info is from the label on the power supply) If I want to update my video card, do I need to update my power supply?

I also see several other video cards, but they also have this problem. They all need a 350W power supply with 12V current rating of 18A or more.

(2) There are some "good" video cards with no specific power supply requirements in Newegg. Does it mean it will work ok with my current power supply, 305W with +12V of 22A?

Thanks

post some links so we can see the specs of the components, but generally, no, you need both at least 20A on the +12V and at least 350W total output.

What PSU do you have (brand and series if known)?

I got this PSU with my whole system from Dell Dimension E521, with AMD 64x2 3800+, integrated video card. I tried to look at the PSU, but I could not see the brand. The label in PSU says max output should not exceed 305W, and +12V of 264W.(that means 22A)

I think that those PSUs are high quality Lite-On units. The official recommendation always has a safety margin to cope with units that overrate/lie about their specs. I doubt you'd have any problems with that PSU, and it certainly wouldn't hurt to try it.
