How do I determine...

[Epid3mic]

I am curious as to how I determine how much power requires? My video card doesn't work and I want to rule out the possibility of not enough power. When I plug the card in the system does't recognize it so I am thinking that maybe there isn't enough power in my power supply to run it. Any and all help is appreciated on this matter. Thank you.

Tell us what your system specs are, and we can tell you what you need.

For the most part, if you have just a single graphics card, a good quality 500W PSU will be able to handle it. If you have some off-brand, or simply a crappy PSU (Raidmax, Coolmax, Diablotek, HEC, etc.), then you could very well be seeing your PSU failing to provide enough/stable power.

This is a pretty good tool, but as fffblackmage said, post your system specs

System specs are as follows:

Amd Athlon II x4 645 @ 3.2ghz
Acer Aspire x1420g mainboard w/ nVidia mcp61 chipset
4gb DDR3
1TB Sata HDD
Antec 9 Hundred Two Computer Case

And the video card?

Also, could you find out what the power supply is.

The video card right now is the on-board video but I have a visontek 4350 hd installed that the system does not recognize. And I just looked and it has a Thermaltake 600w psu.

Ok. It's definitely not the power supply. You're using like 200 watts at full system load, that's with the HD4350. (This means your power supply is massively overkill for your setup.)

Best to replace the video card with something modern if you actually need a discrete GPU
