Gaming rigs are expensive pieces of hardware, often built from the ground up, and are very power hungry. They need clean and consistent power to perform well, and a PSU can deliver the goods. It can also prevent a catastrophic burnout to your expensive gear. A reliable PSU will also stop system instability that causes games to crash and constant rebooting. The units should offer power at 3 volts, 5 volts, and 12 volts, referred to as rails. Plugs attach to the motherboard, CPU, GPU(s), SATA devices, and 5v Molex plugs. It’s worth paying up for a good unit that will run quietly and stay cool.
