Cooler Master Real Power Pro 750 Watt Power Supply

Cooler Master has long specialized in heat sinks and cases, and now they are beginning to offer competitive power supplies to computer users.  Their Real Power Pro line of power supplies was introduced recently, offering a large range of wattages to suit different computer users needs.  Today, we look at the Real Power Pro 750 Watt, which is in the middle to upper range of the wattages 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, 80 Plus Certified and nVIDIA SLi Ready. 

Upon opening the box, you will find the users manual, a power cable, and four screws.  The manual is basic, but has enough information for the user to properly install this power supply.

Here are some of the main features and specifications from Cooler Masters' website:

The Power Supply:

The power supply features a graphite colored casing, with a mirror finish to it. The fingerprints that appear on this power supply are not as bad looking as power supplies with a true mirror finish.

Looking at the side of the power supply, there is an Cooler Master label with their logo on it, the model number, wattage and a condensed specification list. Note that there are four +12v rails, each supplying up to 19 Amps, which is good for peripherals requiring lots of power and has one more +12v rail than the lower 650 Watt model.

Cooler Master offers their specification sticker on both sides of the power supply, which is interesting.

The rear (outside of case) features an large grille to exhaust hot air from the 120mm fan.  There is an on/off switch, 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.  A red led indicator light will tell the user if there is a problem with the power supply, such as a short circuit, power supply overheat or internal component malfunction.

The Cables:

-This power supply does not offer modular cabling, therefore, the cables exit the power supply in one large bundle. 

This power supply features the following cables:

-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 Connector and 2x 6-Pin PCI-Express connector.  There are two sets of cables.  Each one has both a 6pin and 8 pin branch off from the same cable.

-5x Molex Power Connectors and 1x Floppy Power Connectors.

-6x Serial ATA Power Connectors.

Cooling:

Cooling is handled by a 120mm fan in this power supply.  During testing, this fan did speed up quite a bit so that I could hear a wind resistance sound, but it was not loud enough to be annoying when the computer case was closed.  During idle / less intensive tasks, the power supply was quiet, almost as quiet as the 650 Watt Version of this power supply. I was satisfied with the sound characteristics of this power supply.

Inside the Power Supply:

* Taking this power supply apart will void the warranty.

-Inside this power supply, there are two silver finned heatsinks to dissipate the heat from the voltage rectifiers.  There is a large transformer in the middle.  A large sized OST primary capacitor can also be seen.  The layout is a little bit different from the Real Power Pro 650 Watt, but both are built by Acbel.

-The fan inside this power supply is made by SuperRed, which as quite a surprise, because the silent Protechnic Electric fan from the Real Power Pro 650 was not used in this model.  While still quiet, the SuperRed branded fan sounded more whiny when it sped up.  The model of this is the CHB12012BS(E).  It can use a maximum of 0.26 Amps.

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

-4x 120MM fans, 1x 200mm fan

-2x CCFL Lights

(Multimeter Results)

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

The results are great for this power supply, the voltages did not significantly shift.  Everything ran fine during testing; the system was stable and performed the tests as expected.  During the tests, the fan speed did increase.  It increased enough so that I could hear a whirring sound over the testing system's fans and whining from the fan's motor, but it was not loud enough to be of an annoyance.  Installation of the power supply was easy and there were no issues with the non-modular cabling. There is enough of each type of connector to go around, and even enough to power up to two video cards requiring 6+2pin and 6 pin, or four 6-pin PCI-express video cards.  Overall, the Cooler Master Real Power Pro 750 Watt Power Supply is a great performing power supply that offers two 8 pin and two 6 pin PCI-Express power connectors, and a five year warranty for around $120.

Pros +

-Power Delivery and Stability

-Two 6+2-pin PCI-Express Power Connectors

-Five Year Warranty

Cons -

-Fan is whinier sounding than the 650 Watt version of the Real Power Pro.

Techaddicts.net would like to give this power supply a 8.5 out of 10 rating and the Techaddicts 'Great Value' Award.
