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.
