Cooler Master Real Power Pro 650 Watt Power Supply

Cooler Master is well known for their heat sinks and cases.  Their Real Power Pro line of power supplies was introduced recently, offering a large range of wattages for computer users needs.  Today, we look at the Real Power Pro 650 Watt, which is in the middle of the wattage ranges offered by Cooler Master.  The power supply comes in a nice looking box, with a handle at the top for easy transportation.  It is RoHS complaint and nVIDIA SLi Certified.  It also carries Cooler Master's high efficiency label.

Upon opening the box, you will find the users manual, a power cable, and four screws.

Here are some of the main features and specifications from Cooler Master's website

The Power Supply:

The power supply features a dark mirror graphite colored surface, which looks great.  It covers up finger prints better than the more typical silver mirror colored power supplies.  It is even better when you compare it to a typical matte grey colored power supply.

Looking at the side of the power supply, there is an Cooler Master label with their logo on it, the model number and a condensed specification list. Note that there are three +12v rails, each supplying up to 19 Amps, which is good for peripherals requiring lots of power.  This power supply is manufactured by AcBel.

The rear (outside of case) features a grille with many circle shaped holes, excellent for ventilation.  There is an on/off switch, an error led and an AC Power Input.  This power supply offers a full range power circuit and Active PFC, so there is no need for a 110v / 240v switch. The red light indicates if there is a power failure, power surge, short circuit, etc. If its on, something is not right.

The Cables:

This power supply features the following cables (this power supply is not modular:

-A 24-pin ATX power connector

-A 4-pin CPU ATX Power Connector

-An 8-pin EPS +12v connector

-2x  6+2-Pin PCI-Express Power Connectors

-5x Molex Power Connectors and 1x Floppy Power Connectors.  Note that the Molex connectors have a grip on them for easy removal from peripherals.

-6x Serial ATA Power Connectors.

Cooling:

Cooling is handled by a single 120mm fan in this power supply.  During testing, this fan was silent for the most part.  During some parts of the testing, there were faint whirrs, but noting that is distracting.  It could not be heard over the case fans.

Inside the Power Supply:

* Taking this power supply apart will void the warranty.

-Inside this power supply, there are a two dense arrays of heatsink fins to cool off the power rectifiers.  There is a large transformer in the middle and in the upper right of the picture.  Two primary capacitors can be seen to the right, one is slightly smaller than the other.  Quite an interesting layout.

-The fan inside this power supply is made my Protechnic Electric.  The model of this is the MGA12012HS.  It can use a maximum of 0.45 Amps.  Note that this fan was found in the iGreen 600 Watt as well, before they changed it to a louder Super Red fan. This Protechnic fan is very quiet however.

Testing:

For this power supply, the test system consists of the following:

-Antec Nine Hundred Case

-Intel Core 2 Duo E6420 Dual Core Processor @ 3.4 GHz

-ZeroTherm BTF90 Heatsink

-eVGA nForce 680i LT SLi Motherboard

-2GB (1GB x 2) of Mushkin XP2-8500 DDRII-1066 Memory

-320GB x 4 Western Digital 16MB Cache Hard Drives

-2x nVIDIA GeForce 8800GTS Video Cards @ 625MHz Core / 1000 MHz Memory

-Sound Blaster Live! 5.1 Digital Sound Card

-Sony 16x DVD-RAM / 18x Samsung DVD-RAM Drives

-2x CCFL Lights

(Multimeter Results)

*Voltages are at 'Max Load', running 3DMark06 CPU Test 1 and 2 / Deep Freeze HDR test, and read with a Multi-Meter.

The results are great for this power supply, the voltages shifted some (especially the 12v and 3.3v rails), but it was not significant at all.  Everything ran fine during testing; the system was stable and performed the tests as expected.  During the tests, the fan speed did increase a little, but remained silent overall.  During idle / productivity tasks, the power supply stayed silent.  Installation of the power supply was easy and there were no issues with the cabling being too short.  Overall, the Cooler Master Real Power Pro is an excellent value for what it offers.   It is multi-gpu ready with a two 6 pin PCI-Express connectors.  It can be found online for about $130.

Pros +
