Hey guys, I'm new to the forums and not very computer-savvy if you know what I mean. I have a dilemma I hope you can help me figure out. 1st off here are my system specs:
2.8p4 ht, 2x512 3200ram, 120gig seagate hd, radeon 9800pro, onboard sound card, cd/dvd burner, abit it7v2 AGP 4x mobo

Now I want to upgrade my video card to a ATi x800XL 256mb but I'm not sure if my power supply unit can handle it. Currently it is a Enlight 300W psu. Here are some stats for it----> Input: 115V---6A 230V---3A
Frequency: 50-60 Hz
Max Load 300W

If I have to, I will go get a new psu but Id rather not if I didnt have to. BTW, what would happen if my current psu couldnt handle the new video card?
