![]() ![]() 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. Our system also has 2 x 120mm fans connected to it.Īll voltages were read by a Digital Multimeter that was purchased at Radio Shack.When taking a look at the features and protections of the power supply, we expected to be able to report everything was here. We also raised the other available voltages on the board to the middle of available settings. DDR was kept at DDR800 speeds and 4-4-4-12, but we raised the vdimm to 2.4v to stress the system even more. ![]() Our overclocked settings on our Asus p5ne-sli were a fsb of 401, with a CPU mulitplier of 9, using a vcore of 1.5. For this review, stability was determined by running our battery of tests, plus the ability to complete a SuperPi 32mb test run.įor our voltage readings at default settings, we ran everything at stock speeds, and DDR settings settings of DDR800 and 4-4-4-12, at 2.0v. The video card was left at default timings as well for all tests. Timings for our overclocking were left 4-4-4-12 and 2.0v, but the ram divider was set to the lowest possible to take any ram issues out of the CPU overclocking. Our stock speed testing used Corsair DDR2 C6400C4 2 GB kit at 2.0 vDimm at DDR2 800. For our stock speed tests, we ran everything at default timings for the CPU. All tests were run using a clean install of Windows XP Professional with SP2. ![]()
