Well, PC Perspective has another PSU review up. It's another Silverstone unit, this time a 500W unit from their Element line. Note: The maximum combined load for both +12V outputs is 36A (432 watts). That means that 86% of the power supply’s rated 500W output is dedicated to the +12V outputs. This illustrates a major shift that has occurred in the PC power supply industry over the past few years. Less power is available on the +3.3V and +5V rails and more power is available on the +12V rail. It used to be that the +3.3V and +5V rails were used to supply power to the CPU but when the Pentium 4 and Athlon 64 CPUs came along, motherboard manufactures started using the +12V rail to supply power to the CPU via onboard voltage regulators.
