![]() ![]() Built with industrial and professional power users in mind, key features of the 950W Mk II include a Single +12V Rail for maximum and efficient power distribution, a generous thermally controlled 135mm double-ball bearing fan for maximum airflow at near-silent audible noise levels, extremely tight and well regulated electrical noise and ripple, an ideal array of connector types for each wattage, and ultra-high efficiency, converting up to a full 88% of AC to DC power at typical loads. A thorough update, the new Silencer Mk II strikes the right balance between server-class industry standard topology and the cutting-edge of enthusiast computer power supply design. It confuses us even more since temperature is already being monitored in order to control the fan speed.The new Silencer Mk II 950W from the power supply experts at PC Power & Cooling is another leap forward for the legendary Silencer line. What still shocks us the most though is the lack of Over Temperature Protection within the unit. The relatively low combined output of the minor rails will limit some heavy overclockers, but shouldn't have any impact on those who run everything at stock speeds. There are some minor issues with the unit, but nothing that will be a deal breaker to most. There are very few Platinum rated power supplies available above 1000W, but OCZ is now on the list. Let's not forget about the efficiency of the unit either as Platinum efficiency at 1200W isn't an easy task. DC output quality is just as fantastic as noise seen on the 12V rail is under 30mV at 1000W. Voltage regulation is fantastic from start to finish with all rails at 2% across the board. As the results above show, the unit does not disappoint on either of these. As such, we expected not only lots of power, but quality throughout with great performance. Final ThoughtsĪt 1200W the Silencer Mk III 1200W is the highest wattage Silencer series power supply to come to market. As you can see, the Silencer Mk III 1200W passed on our bench and wasn't close to failing at any point. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. The PC Power & Cooling Silencer Mk III 1200W is rated for 80 PLUS Platinum efficiency. During Test 6 under a load of 1000W, the oscilloscope showed a maximum of 28mv on noise on the 12Vrail. When we increased the loads in Test 3, the ripple climbed to 18mV at a little under half load. During Test 1, we saw 13mV of noise on our scope. Many will be pleased to know that while the 600W model only carries a five year warranty, the new 1200W model is backed by a solid seven year warranty.ĭC Output quality for the Silencer Mk III 1200W was excellent and well within specification. Tiger Direct does have the unit for sale for $289.99, but after shipping of $9.16, that still raises the final price to $299.15. Some poking around on the web shows that not many are offering the unit much, if any cheaper. The PC Power & Cooling Silencer Mk III 1200W power supply has an MSRP of $299. Sleeved native and modular cables, 80 PLUS Platinum efficiency, and being rated for 100% continuous output at 50C round out a solid list of features. Aside from OTP, the unit offers everything else. We were sure that this had to be a mistake however, OCZ informed us that OTP was not included with the Silencer Mk III 1200W. While going through the protections offered, we found that Over Temperature Protection wasn't listed. When taking a look at the features and protections of the power supply, we expected to be able to report everything was here. ![]()
