Cooler Master Real Power Pro 1000 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'll take a  look at the Real Power Pro 1000 Watt, which is in the 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 higher gauge power cable, a cooler master case badge, and four black screws.  The manual is basic, but has enough information for the user to properly install this power supply.

A 14 AWG power cable is included

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

The Power Supply:

The power supply features a glossy graphite colored chassis that has a reflective surface.  It looks great, but fingerprints may show up quite easily.

*Note that the specification labels are on both sides of this power supply, which is great for referring back to the model of this power supply when it is inside a computer case.

*Note that the specification labels are on both sides of this power supply, which is great for referring back to the model of this power supply when it is inside a computer case.

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 six +12v rails, with +12v rails 1-2 and 5-6 supplying up to 18 amps and +12v rails 3-4 supplying up 28 amps, which is plenty of power for peripherals requiring lots of it, such as a quad core processor and/or a multi-gpu system setup. Enhance seems to be the manufacturer of this power supply.

-A large 135mm fan cools off the power supply's internal components

The rear (outside of case) features a large grille to allow exhaust air to exit from the power supply.  There is no on/off switch (which I personally do not like, because if these is a need to shut off the computer, you would have to pull the plug from the wall or the power supply itself instead), 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 two color LED indicates whether or not there is a problem with the power supply, such as when a Over-Voltage, Under-Voltage, Over-Temperature, Over-Current, Over-Loading, and Short circuit occur.

The Cables:

This power supply is not modular, so a large bundle of cables are protruding from the back of the power supply.

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 CPU Power Connector

-2x 6-pin and 2x 8-Pin PCI-Express Power Connectors.

-6x Molex Power Connectors and 1x Floppy Power Connectors.

-8x Serial ATA Power Connectors.

Cooling:

Cooling is handled by a single 135mm fan in this power supply.  When the system is idle, this fan is a bit loud, making a constant whirring sound. During testing, this fan stayed at the same speed throughout the tests and it the sound is only slightly louder than the test system's fans.  The fan speed did not seem to change at all.  Note that this power supply's fan is quieter than most of the power supplies that we have tested.  It is noticibly quieter than the OCZ ProXStream 1000 Watt and the FSP Kingcraft 1000 Watt.

Inside the Power Supply:

* Taking this power supply apart will void the warranty.

-Inside this power supply, there are two thick large finned heatsinks and one small thick finned heatsink to cool off the voltage rectifiers.  Two large transformers are located in the middle and two large Teapo primary capacitors are tucked underneath one of the large finned heatsinks.

The fan inside is a Young Lin branded fan, with a maximum draw of 3 Watts. 

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

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

The results were excellent for this power supply, the voltages did not budge at all.  Everything ran fine during testing; the system was stable and performed the tests as expected.  During the tests, the fan speed stayed the same, which was audible, but not enough to be bothersome, which is uncommon in 1000w+ power supplies.  Installation of the power supply was easy and there were no issues with the PSU fitting in the case as this PSU is slightly larger than lower wattage power supplies.  There are plenty of power connectors to power most components found in a PC enthusiasts system.  I did like the fact that there were eight SATA power connectors to allow for more optical or hard drive storage options.   Overall, the Cooler Master Real Power Pro 1000 Watt is one of the best 1000 watt power supply that we have seen and and it offers enough power to supply the most power hungry computer systems.

Pros +

-Excellent Power Delivery and Stability

-Two 6-pin and Two 8-pin PCI-Express Power Connectors

-PSU is quite heavy

-nVIDIA SLi certified

-5 Year Warranty

Cons -

-Not modular

-No on/off switch
