Restoring old AGP pc


Jul 11, 2009
Hello toms hardware community, I have a little project I want to do a nd was wondering if you guys would offer some insight. I have an old gaming pc that I used in high school for 4 years, and had a lot of fun to, now I'm home from college and wanted to restore it so I could play a few older games (HL2, CSS, TF2, etc).

I would need a new graphics card as my geforce 6800 died 6 months ago, and a new PSU which blew up this morning. this is an AGP system and this will be the last I upgrade it before it is retired for good. current specs.

intel 865glc mobo
p4 3.0ghz processor
120GB hd
geforce 6800 (dead)
400watt psu(dead)

I am unsure if anything was damaged when the PSU blew, I was looking online for new agp cards and psu's and found 2. hd 3850 is the top of the line, just need to get an adequate psu to go along with it..only bottleneck is CPU but thats fine.



PSU, I want something that can run the hd 3850 AGP..just unsure if these new PSU's are different than older ones 4-5 years ago..mine says Ulta PSU ATX 400watt.

I am inexperienced at installing a new PSU so any helpful links to help me out? Would you rec commend me buying a cheap PSU and setting it up to see if anything else is fried first?

thank you for your help.

I'd estimate that 50% of requests for help here when a PC fails are due to psu. Please don't buy a cheap one.

Antec Earthwatts are excellent, not so much the Basiq. Please consider these instead:

PSU installations are fairly straightforward electrically. Since the cables are all "keyed" its hard to make a mistake. Physically, you may have to remove other stuff depending on your case's design. There are probably walkthroughs on the web :) Google for them.

The mobo has two power connectors for itself. One is either a 20 pin or a 24 pin. Both the recommended psus have a 20+4 pin connector which means you can adapt it regardless. If your mobo is the Intel D865glc, it appears to have a 4-pin cpu power connector, as do both psus. So you are all set.
