Even with a lot of money and the time to put together a higher than high-end rig these consumers are as looking for the stability, quality and energy saving characteristic of a good power supply not just big numbers on the rails. Coolermaster was generous enough to let us take a look at one of the biggest power supplies on the market with a Gold efficiency rating. It is called the Silent Pro Gold. The series lineup consists of six models ranging from 600 to 1200 watts.  

Introduction to the Coolermaster Silent Pro Gold 1200W

Over the past few months we have seen a few power supplies released with the with the Gold 80Plus standard. Many of these units have been under the 800 watt power rating. And in many cases this is plenty of power for most users. Even for those running multi-GPU set-ups a hefty 800 watt power supply will do the job. And if that isn’t enough there is a fair share of quality 1k models out there. But we have yet to see one with an efficiency rating as high as our next review sample.

Closer look

Before we get into the descriptive portion of this review I want to talk about how much power these units contain. We stated there are six different wattage models making up the Silent Pro Gold line. The 600, 700, 800 and 900 watt models should be enough power to run most multiple GPU system up to three. But a lot of that relies on the cards used. But the bigger 1k and 1.2k unit can manage the power needed to support quad SLI/Crossfire of any variation.

Our 1200w model has a total of 1176 watts running through the single 12v rail. Coolermaster went with the single rail due to their belief that a single rail is more stable and that it adds to the efficiency of the unit. The 3.3 and 5 volt rails share a combined 150 watts. The 12v rail has a total of 98A. In the CM labs the supports a maximum output  1440 watts.

 

According to Coolermaster product page for the Silent Pro Gold the 1200 watt model has an above 92% efficiency rating at 50% load and ending at an impressive 90% at 100%.

Now, lets get into the descriptive segment of the review. Removing the Silent Pro Gold 1200 from the box you are met with nice flat black power enclosure trimmed with white and gold accents. Coolermaster eliminated any forms of flash and bling from the unit making it a unit for all that needs this about of power in their rig. The gold and the gold efficiency rating seem to go hand in hand.

The unit is small for a 1k plus wattage power supply measuring in at seven inches in length. Putting it in the length of most other 700 to 800 watt power supplies. So, the Silent Pro Gold should not have any issues fitting into most mid-size cases.

For cooling and ventilation the unit comes with silent 135mm cooling fan which pushes air through the unit out the rear of the enclosure.

 

The Silent Pro Gold is a modulator unit well partially modulator as the main ATX, aux power plugs and three of the PCIe extensions. As the permanent cables exit the PSU the shell is designed in which a way as to not cut the cabling. Basically no sharp or rough edges.

 

The open plugs are designed to accommodate the seven other extensions which are SATA, peripheral and PCIe for graphic cards. The modular cables are coated in rubber and are flat. This maximizes air flow inside the case. Neat cable management is possible but can be tricky due to the restrictions of the rubber coat.

Testing and Results

We did not go through our usual testing method for power supplies. as we felt it would have been useless for a power supply of this size. not being able to afford the pleasure of having multiple GTX480 cards we would only be able to put a small load on the Silent Pro Gold 1200.

But what we did do was use the unit in a few different test benches we have around the lab. and there was never a hiccup. And noise was a non-issue as every other component we were testing like coolers and graphic cards were louder.

Honestly, we can not wait to read other sites reviews with the means to really put this a load on this beauty. we feel it will test with flying colors.

Conclusion

Coolermaster are mostly known for producing some of the best cases of all time. Many of these classics are still in use by many people today like the Stacker, Cosmos and anything coming from the ATCS lineup. But Coolermaster is here proving today they are major players in the power supply business as well. We have reviewed our share of power supplies in our time but this is a first. The benefits of having a high powered high efficient power unit is something we have yet to get a hold until now.  

Such a unit entitles the end-user the ability to have enough juice to power any gaming rig on the planet. Imagine quad GTX480 video cards, the new EVGA SR-2 motherboard and a raid array fast enough to surpass the sound barrier all powered with a Gold rated power supply. And at the same time have efficient rating to keep the electricity bill at bay. But with such a system I am sure that person isn’t worried about a measly utility bill.

But wanting the stability and reliability that comes with a power supply like the Silent Gold Pro is what one would be looking for. Maxing output at 1440 watts the Silent Gold Pro will keep things in perfect working order at max load. This is what we get with a 80Plus Gold rated power supply with an advertised 1200 watts of power.

The look of the Silent Pro Gold as classic and sleek, lacking any form of flash the unit is ideal for any situation.  But the modulator cablings are what will do it for most of us. But Coolermaster approach is slightly different as the cables are flat and use a rubber seal for better airflow.

Normally, a power supply like this I would put into storage until it was time to break it out for some other reason. But this will not be the case for the Silent Gold Pro as it will become part of my dream rig I am in the middle of building. So, we will see this one again
