I have no warranty on it now mostly use my laptop put was going to repair it and give it to my son not sure what psu it is
well you can get a replacement PSU at a decent cost (assuming you are in North America). was this going to be a PC for gaming or school? what are the PC specs? just a hard drive, ram, cpu, etc., or do you have a video card for gaming in it? It it in a tower case or slim line case?
