I'll have to check the brand of psu when I get home from work. I think it might be an Antec PSU, but I'm not sure.
This is a third system that isn't used much and has a K6-2 550 in a Gigabyte GA-5AX mb. I had problems with this setup and the video card until I put a V5500 in it. This solved the problem of power to the video card because the card gets it's power from the psu, not the mb. I've also heard newer video cards that don't need as much power will also work. If I get this new setup, the old will be for sale. 😉
