1000W-1200W Roundup: Five High-End PSUs
by Martin Kaffei on December 9, 2010 1:20 PM ESTCooler Master Silent Pro Gold 1200W
The 16cm long Silent Pro Gold is Cooler Master's latest creation. The package comes with flat modular cables with gold colored connectors, a manual, some screws, and a power cord. Cooler Master told us that there are some special technical features like the transformer core mounted to the heatsink. They have reduced some power loss from terminal pads because many components have direct contacts. Cooler Master offers a 5-year warranty.
| Cables and Connectors | ||
| Fixed/Modular | Main | 24-pin 50cm |
| ATX12V/EPS12V | 4+4-pin 60cm / 4+4-pin 60cm | |
| PCIe | 4x 6/8-pin 60cm + 6-pin 10cm | |
| Peripheral | 3x SATA 50-70cm / 3x SATA 50-70cm / 3x SATA 50-70cm | |
| 2x Molex 50-60cm /2x 50-60cm + Floppy adapter 15cm | ||
The two 8-pin CPU connectors and eight PCIe connectors are satisfying. However, the peripheral cables are very short and there are only four Molex connectors for fans and other peripherals. This is not the best solutions for large cases, but it's good enough for triple-SLI and quad-CrossFire setups.
The 135mm fan from Young Lin, model number DFS132512H, is the same one like in the AeroCool V12XT--not very silent nor professional. It's a typical sleeve bearing type spinning at up to 1800RPM with eleven fan blades.
On the right side you can see both DC-to-DC VRMs. This PSU has two main caps from Nippon Chemi-Con, a very small transformer, and a clean soldered cable management PCB. The L-shaped heatsinks should help to increase airflow. Cooler Master has no real single rail for +12V and OCP to protect their multi rail design. The active PFC circuit allows Cooler Master to sell and use this power supply in countries with 90-264VAC input voltage. The placement of parts near the power inlet seems to be very chaotic.

Martin,
Just curious, how do these PSUs compare to existing units which have been out for
a while, eg. the Thermaltake Toughpower 1000W Modular? Any thoughts?
Ian.

Hey,apart from the fact that the Thermaltake (CWT 2x 500W Design) is less efficient than most actual PSUs, the voltage quality is almost perfect.
DC-DC, good caps and filtering, not faraway from Corsair HX. A proven design.
Cooling could be better, since many components are close together. However, still uncritical temps.

It would be great if Anandtech could do a roundup of a few 550w to 750w PSU units, as most mainstream users are using PSU units within this wattage range.
