The best thing you can do for your system is pick a strong, reliable power supply. What constitutes a “strong, reliable” power supply you ask? This would be a power supply that can provide the cleanest power source possible while maintaining very stable 3.3, 5, and 12 Volt power rails. It should also be able to maintain very acceptable voltages no matter if it’s running at 50% or 100% load. Antec seems to think their new True Power 750 Watt (TP-750) Power Supply is up to this task.
