Cooler Master RealPower 550W

Fan Noise

The fan of the RealPower 550W is temperature controlled. The higher the PSU's internal temperature, the faster the fan will run.


Especially under load this PSU is not very quiet.

Value and Conclusion

	The Cooler Master RealPower 550W is sold for around $110 which is certainly not cheap but the added connectors and power meter have its price.
	Three 12V rails PCI-E power connector 24 Pin ATX, 20 pin adapter included EPS and Workstation connector Watts Viewer Nice black finish
	Cables not sleeved Takes fingerprints A bit loud 12V line could be more stable
8.5	Cooler Master has engineered a nice PSU with a load of extra features. The Power Consumption readout is a nice gimmick for your case, especially if you are into case modding and want to add a custom touch to your system. Three 12V rails make sure that your system is stable at all times, an extra PCI-Express power connector completes the package. A bit more stability on the 12V line would have been nice, but the line is far from being unstable. However, for a price of over $100 I would expect that all power cables are sleeved.
