Posted by on Saturday, October 20, 2012 - 4:30pm

The Silencer name has been a part of PC Power & Cooling for almost four years now. The third generation Silencer Mk III 500W offers all the current advancements that that the previous two models do not. Obviously, as times come and go products must be updated to allow the consumer to take advantage of the current technology. In the case of the new 500 watt Silencer power supply that comes in the form of a Bronze certification, modular cables, a more powerful 12v rail and greater under- and overload protections.

PC Power & Cooling Silencer Mk III 500W Power Supply Review

 

Introduction

We have been reviewing products from OCZ for a very long time. But today will be the first time we have reviewed anything form them under the PC Power & Cooling marker which they just forces with back in 2007. And we feel it's an honor due to the fact that PC Power & Cooling is a local company to Pro-Clockers right here in San Diego.

Closer look

Viewing the Silencer Mk III the first thing that stands out is the surface color. This is not the first time that we have seen a white power supply but the option does broaden your choices a lot when it comes to your next build. When it comes to white components it is what black was to beige in the days of old. The white chassis is ideal for cases like the BitFenix Prodigy that we are currently building up.

Along with the white paint job are black and gray labels that surround the unit, like on the sides there are large labels depicting the model name and wattage output. The company keeps it all tactful with on bling. 

Currently, the unit is offered in three other size variations which would be 400W, 600W and a massive 1200W unit. Of the four models available only the 1200W is Platinum certified while the rest have Bronze certifications. The 500W we are looking at today has a total of 38 amps on the single 12v rail. This should be ample to power some of the higher mid-range video cards like the NVidia GTX 670 and the Radeon HD 7950 cards singly.

To cool the internal of the unit is a 120mm double ball bearing fan that blows air over the internals. The fan is protected by a thin black grill with the model logo in the middle.

The backside of the power supply is well vented and consists of the typical power toggle switch and power plug.

The Silencer Mk III is partially modular as the SATA, Molex and one of the PCIe cables are detachable. The rest including the main ATX, EPC and one PCIe are permanent fixtures.

Results

We know that testing a power supply on a loaded system is not the very best way to do so, but you cannot 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

The PC Power & Cooling Silencer Mk III 500W looks to be a great little power supply for those not looking for a beast. We find that it was ideal for some of the small rigs people are quickly getting into. In our case, we sled it into an all-white BitFenix Prodigy ITX case and it looked and performed perfectly. The unit has ample power to push the higher-end graphic cards as well as a good overclock on that GPU as well as the CPU.

There may be some talk about the unit not being 100% modular but I have always said what's the point when the permanent cables will have to be used regardless. The only advantage I see to all the cables being detachable is to make individual sleeving easier.

We found the PC Power & Cooling Silencer Mk III 500W selling for as low as $70 before any rebates which we found $20 worth of rebates to lower this to $50. It is hard to find a Bronze of high quality at such a low cost.
