Technical data …
The basic weight of the CM Silent Pro Gold is approx. 2.5 kg (shipping weight approx. 4 kg) and the overall size is about 150x180x87mm.
The technical data of the 1000 Watt power supply can be checked at any time on the attached label. The Coolermaster Silent Pro Gold RS-00-80GA-D3 provides following voltage levels and amperages: +3.3V 22A ; +5V 25A ; +12V 82A -12V 0.30A ; +5VSB 3.5A
All voltages could be tested on different loads also with external measurements very well and pointed to a good technical conversion of the switched power supply. The combined total output values should not exceed the following ratings: At +3.3V and +5.0V up to 150 Watt, +12V up to 984 Watt and total consumption of all power lines should not exceed 1000 Watt (continuous operation according to manufacturer with maximum load and up to 1200 Watt peek).
These are manufacturer values, which one should not exceed, to avoid overloading and too high heat development. Apropos overloading – of course the PSU offers also all kinds of short-circuit-, overcurrent-, output- and input power protection, (OCP, SCP, OVP, OPP, UVP, OTP) which was tested successfully in the test attempt. Nevertheless one should avoid any installation failures, because under certain conditions it is possible to destroy the PSU, or other parts of the PC (up to a fire by e.g. cable fire with loose or wrong connections).
Furthermore, the power supply has an active PFC (Power Factor Correction) for the reduction of the reactive power, the EMV noise and improvement of the efficiency. Meanwhile at least the more inexpensive less efficient and bigger passive PFC (upstream throttle) is legally prescribed. So also here the company Cooler Master saved by no means and offers a power pack with 80PLUS GOLD certification, which has a .99 PFC value.
Own measurements of the test system with ASRock 890GX Extreme3 motherboard, AMD Phenom II 710 X3 CPU, 4GB DDR3-1333 memory, hard disk and ATI Radeon HD4870 PCI-E 2.0 video card resulted in an idle value of 124 Watt and a maximum value with full system load of 216 Watt. Switched off in the S5 mode, the test system with the Silent Pro Gold power supply needed max. 10 Watt. Above all the idle value of 124W with small load is thereby much lower than the value of previously tested Cooler Master Silent Pro M500 power supply with lower 500W total power of approx. 140 Watt. More power supply reviews will published here.

The MTBF (Mean Time Between Failures) of the power supply is according to the manufacturer with 40°C about 100,000 hours, which distinguishes finally the reliability of the power supply, this time between 2 possible errors is enormously good.
For the high durability contributes also the high-quality Japanese 105 °C capacitors and also the 135mm fan. The 135mm fan reached thanks to temperature control an optimal adjustment of the volume for necessary cooling and the fan is very quiet with medium PSU load. So the CM Silent Pro live up to its name.
