Technical data …
The basic weight of the CM 700 is approx. 1.85 kg (shipping weight approx. 3.2 kg) and the overall size is about 170x150x85mm.
The technical data of the 700 Watt power supply can be checked at any time on the attached label. The Coolermaster 700 RS-700-AFBA-G1 provides following voltage levels and amperages: +3.3V 25A, +5V 25A, +12V 58A, -12V 0.5A and +5VSB 3A.
The combined total output values should not exceed the following ratings: At +3.3V and +5.0V up to 125 Watt, +12V up to 696 Watt and total consumption of all power lines should not exceed 700 Watt.
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. 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, (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 energy efficent active PFC (Power Factor Correction) for 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 a very low idle value of 147 Watt and a maximum value with full system load of 224 Watt. Switched off in S5 mode, the test system with the V700 power supply needed approx. 1.8-3 Watt. Above all the idle value of 147W with small load is thereby higher than the very energy efficiency Cooler Master Silent Pro Hybrid 1050W power supply with an consumption in idle of approx. 122 Watt in spite of the very high 1050W total power. More power supply reviews can be found here in our hardware reviews page.
You can calculate the current consumption and cost of electricity easily:
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 Protechnic MGA13512XF-O25 12 Volt 4.56 Watt 135mm fan reached thanks to temperature control an optimal adjustment of the volume for necessary cooling and the fan is very silent with higher PSU load. Fortunately even for the Bulk-Caps inside of this power supply high-quality 105°C capacitors are used, which offers a Hold-Up time of approx. 17ms on full load.
