|The power supply (aka PSU) is arguably THE most important piece of hardware in a PC. You can have the greatest board ever made, fastest CPU, kickazz video card, etc, but it's all useless if the PSU isn't up to snuff. And you should NEVER buy a PSU based on wattage alone. For instance, going from a 300W PSU to a 500W PSU isn't necessarily an upgrade. There are plenty of 500W el-cheapo units out there that could barely power up an old Pentium 1 system. The PSU needs to be a quality brand name unit plus it needs to have the proper amperage specs. Decent quality 500W PSUs start at about $50 & go up from there.|
But if the PC's in the shop for repair, why are you posting?
