Should I worry about power supply requirements when looking for a high performance graphics card?

by on February 10, 2009

Q: I recently purchased a P4 3.2GHZ tower computer from eBay. The computer has a PCI-E 16X expansion slot on it. The PSU is 340 watts. I do not want to upgrade my PSU.

I want to play some of the newer games like Fallout 3 and Oblivion. But I am not a huge graphics addict.

What would you suggest for video cards that fit with my current system configuration? I have shopped from NewEgg in the past, but many of the video cards do not even list a power supply requirement. If it isn’t listed should I even worry about the PSU?

    Lots of video cards today are a lot more energy efficient than they used to be. Additionally, a lot of the marketing around PSU upgrades has been a bit overkill.

    I’d suggest you try out this PSU calculator and what kind of results you get: http://extreme.outervision.com/PSUEngine

    Unlike many of the other calculators like it out there, it has the added advantage of not being put together by a company that wants to sell you a power supply!

    Let us know how that goes for you. Also, please let me know the following:

    What brand is the PSU?
    What video cards are you considering?
