Cooler Master Silent Pro M 1000W (Page 2 of 4) | Reports

Page 2 - Physical Look - Outside

The matte black finish of the Silent Pro M makes it look really sleek in my opinion. It really accentuates its effect of being a high end power supply, despite the fact that it is not necessarily priced to be one, which is a great thing. The clean matte finish is combined with no LEDs or any flashy things on the inside to create a clean, mature look. The large bottom mounted 135mm fan contributes to good airflow at lower rotations in order to generate less noise. No other fans are implemented in hopes of keeping it at an absolute maximum in terms of silence. Honeycomb mesh is pretty standard nowadays for most PSUs, however there is one thing that is different on the Cooler Master Silent Pro M -- and that is the protruding mesh allowing for more space and airflow. This may become an issue in some older cases, as they may not have a full opening for power supply mounting, and could cause some difficulty in installation.

As aforementioned, the protruding honeycomb mesh is used to cover most of the rear side of the Cooler Master Silent Pro M 1000W-- AC line input as well as power switch is placed near the left side on the same surface. Cooler Master's Silent Pro M 1000W also features automatic full range (100V-240V) AC line voltage selection, as is the case with most modern power supplies. This feature makes it almost seem awkward that they needed to mark this product for different regions; however this is most likely a reference in respect to its included power cable.

Cooler Master's Silent Pro M 1000W measures in at 150mm x 165mm x 86mm; making it just a bit longer than other power supplies with an average length of 150mm. Additional headroom is needed for more components, as this is a higher output power supply. The added length could again prove difficult to install in some cases -- but chance are if you need this much power, it's pretty likely that you have a pretty high end computer. For that reason, it is unlikely that the user will have a beige box. That's not to mention that a beige box isn't likely to provide adequate cooling anyway.

Flipping around and turning the Cooler Master Silent Pro M 1000W over, the bottom mounted 135mm fan is unveiled. A 6-ring fan grille is used in this power supply; as compared to the relatively more standard 8-ring fan grille. In the very center of its fan grille is a Cooler Master logo;; which basically occupied space for where two more rings are usually located. This fan is nicely centered on the PSU, and the fan grille is removable from the outside by removing four Phillip-head screws. Four other screws are found in the border which are used to take apart the Silent Pro M. Of course, this breaks your warranty, so it is not recommended that the PSU be opened unless you have a very good reason haha. Speaking of which, Cooler Master provides a good five-year warranty with their Silent Pro M power supplies.

Only three cables are not modular; instead they are hardwired into the power supply. The three cables consists of the 4+4 pin ATX12V cables (They're technically two cables; usually combined for one 8-pin EPS block where necessary), and one 20+4 pin motherboard connector. The rest of the cables are modular. There is room for six 6+2 pin PCIe cables, and five Molex/SATA output connectors, at the back of the power supply. Talk about a loaded power supply, it can take anything you throw at it physically 3-Way SLI? No problem, the Cooler Master Silent Pro M 1000W is here to accommodate anything you may need it to. And up to 1000W rated power output to boot!

Located on the left side of the power supply is the power output/rail configuration information label. This includes data on the rails (No kidding, haha), and of course some of those assorted certifications and patents. The funniest thing here is the Engrish statement, "AS SEALED STICK WAS REMOVED, LOST, OR DAMAGED, IT SHALL BE OUT OF WARRANTY VALIDITY". (Google Translate? Haha - Editor) In summary, by opening the power supply, you void the warranty. Well, at least that is what I think it means anyway. At least on paper, we can see how powerful the Cooler Master Silent Pro M 1000W is specified to be. Combined maximum continuous DC power output for this power supply is rated at 1000W, and 1200W maximum for boost. Sometimes more power may be necessary upon initial system boot, or just a temporary burst or spike in usage. The +3.3V rail and +5V rail has a combined output of 183W. Separately, the +3.3V rail theoretically gets a maximum output of 99W; while the +5V rail theoretically gets a maximum output of 130W. Both calculations were done with the following common power formula: P=IV. The +12V rail is notably not split into virtual rails, giving a single +12V rail providing a maximum DC output of 960W. This is excellent, since there is significantly less overhead to maximize efficiency and available power. All in all, the maximum continuous DC power output is limited to "only" 1000W continuous and combined.

As stated before the following cables can be connected and disconnected from the power supply:

- PCI-E 6+2 Pin x 6
- 4 Pin Peripheral x 6
- SATA x 9
- 4 Pin Floppy x 1
- PCI-e Y cable x 2 (One PCI-e 6+2 Pin extends to two PCI-e 6+2 connectors)

The 4+4 pin ATX12V cables and the single 20+4 pin motherboard connector cannot be disconnected, as mentioned earlier. All these cables are sleeved, and make it look more organized as well as providing less hassle than non-sleeved ones would. In addition to it being sleeved, they're also the flat type -- think of it like the old PATA cables -- so it's easier to manage around your chassis. Also to mention that there are probably more cables here than most people would use. Most people won't be using six PCI-e connectors (Triple SLI), with nine hard drives, and six other things that require Molex 4-pin connectors haha. It even has a PCIe splitter for a seventh PCIe graphics card!? Either way, cabling should be a cinch with cables of good length and quality. And thank goodness it's modular!
