So today we are peeking at the Silent Pro GOLD 600 Watt power supply. Cooler Master is actually releasing several models within this specific range, these PSUs will be starting at 600 Watt going all the way up to 1200W. The 700W, 800W and 900W models are all ready for 3-way SLI or CrossFireX, while the 1000W and 1200W models handles quad SLI or CrossFireX as well as the latest XL-ATX motherboards with support for dual 8-pin 12V connectors.
The 600W unit tested today starts out with a single 48A 12V rail, while the 1200W model ups this to an insane 98A, you read that right. ONE rail that powers the entire 12V rail, kinda like PC Power and Cooling does as well.

With 600 Watts the PSU falls into the mid-range to high-end category. Although not exactly Kilowatt material, it most certainly is capable enough of running a dedicated high-end PC. Especially when you realize that Cooler Master made sure your power supply can have a higher peak wattage, this 600 Watt model for example can take 576 Watts on just the 12v rails, then 150 Watts on the 3.3 / +5V rails, and a little more on the -12V and +5Vcb headers tallying everything up towards a combined DC output of 747 Watts, but we may and should not measure that way.
The product is a certified SLI/Crossfire ready product for up to two cards, two PCIe PEG leads will offer two 6/8-pin (DXX) headers and twp 6-pin headers for graphics cards. That is more than sufficient for any 2-way multi-GPU setup, especially with a blistering 48 Amps available on that 12v rail.
But let's go to the next page and talk about efficiency for a bit...
