Introduction to the Cooler Master Silent Pro Hybrid 1050W Supply

Cooler Master is no stranger to making some pretty reliable power supplies. If you take a look at our Power Supply review section you will see there are many different models by them, encompassing a wide range of users from the causal PC user to the all-out PC gamer. Their Silent Pro Gold 800W, as it just so happens, is pumping along in my daily rig as I type this new review.

Cooler Master’s take on the Silent Pro Hybrid

Silent Pro hybrid 1050W is part of Cooler Master’s first fully modular power supply series with integrated dual 7V fan ports. It utilizes a single powerful +12V rail that operates at over 90% efficiency and carries an 80Plus Gold

A fan speed controller is included in the package. It occupies a 5.25” drive bay and enables a user to control the Silent Pro Hybrid 135mm Silent Hydraulic Bearing fan along with up to three system fans.

Closer look

Lets start this off by getting right to the main feature here on the Silent Pro Hybrid (SPH): the fan controller. The all black controller is mounted into an empty 5.25” drive bay and has two large dials that allows the user to manually dial in the speed of the fan, as well as a switch for Auto and Manual modes. CM decided to provide this option in order to keep from requiring a motherboard fan header, where this option lets the user determine when it is time to turn up the flow of the fan. What’s more is if you wish to controller a couple of system fans as well, it is possible with this unit as there is a 7V power connector tied into the unit can for control of up to three additional system fans. The switch in the middle is there if you want to turn over control of the fan over to the power supply’s internal thermal control circuit.

Here we have the reverse side of the fan controller and all the necessary connections to make things happen. The controller uses 3-pin connections to for the system fans and a special connector to attach to the power supply. The controller will regulate voltage from 3v to 12v.

Now, we take a look at the main piece in the box which is the power supply itself. As far as visuals are concerned, CM went a different route with the Hybrid model by giving it a slightly rough texture that covers this new unit. The previous Gold model was more flat black with smooth coating.

The SPH uses a 135mm “Super Silent” fan to cool the internal workings of the unit. And what makes this fan special, as well as the PSU itself, is the fan is not required until the system hits at least 200W of load. The fan sits underneath a black mesh grill, with a silver brushed-aluminum accent plate secured with four Allen screws. It really adds a nice touch to the unit.

The sides of the unit just feature the initials of the model and the unit’s wattage rating. The model we are testing here today is the 1050W unit. CM offers two others in the Silent Pro Hybrid series as well, coming in at 850W and 1300W.

The rear of the SPH uses the typical honeycomb opening to allow warm air to escape.

As you can see from the product label stickered to the top of the unit, the SPH 1050W is aimed at rigs pushing a lot of power. This possesses a single 12V rail that is capable of 82A, for a potential max of 984 watts. With such numbers, the unit can power multi-GPU setups.

One feature that many will agree is nice is the fact the SPH is completely modular, right down to the ATX 24-pin cable. Each extension is flat (wires not left loose) and rubber coated. Not the typical wiring style which requires sleeving in order to look nice, like most other power supplies. And also, CM made sure the cables are slightly longer for better cable management.

Results

We know that testing a power supply on a loaded system is not the very best way to do so, but you can not overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multimeter. Those sites and the methods they use should be the true means of determining how good a power supply really is; however, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.

Conclusion

Once again Cooler Master is showing they are about quality and progression. Growing on the reputation of the highly popular Silent Pro Gold series, the new Silent Pro Hybrid models takes things to another level. Present in both models is the same high reliability, but the SPH has to ability to run run silent with the fan completely off when running under a light load, to eliminate noise from the system. Once the system requires more than a 200W load the SPH will turn the fan on, while ramping up the fan speed as load increases.

Furthermore, the unique features continue with the SPH also including a fan controller that uses a 5.25” drive bay. Capable of not only controlling the SPH’s 135mm cooling fan, it also has an Ace up it’s sleeve with the ability to control three additional system fans. That means the Silent Pro Hybrids are essentially two products for the price of one.

To top it off the SPH does have all the under/over load and voltage protections that we require in a power supply that will be powering our delicate and expensive components. An 80PLUS standard is also an important feature when searching for a power supply and the SPH has achieved the Gold certification.

We here at Pro-Clockers, as fellow consumers, also love components and hardware that look good. The SPH is one of the better looking power supplies we have seen. From the brushed aluminum fan grill to the textured coating that protects the internals of the unit.

As stated before, the SPH is offered in three different models: 850, 1050 and 1350 watts. MSRP pricing being $199, $249 and $299 respectively.
