“Starting off with the build quality and design of the Silencer Mk3 we have a unit which delivers in all the important areas. Inside the quality remains high with branded, high spec components such as the 105°C Japanese capacitors. The stand out performance aspect is noise level though with this PSU remaining very quiet at all times. Added to this is a 5-year warranty which gives us confidence that the PSU will outlive the majority of components in our system. Those looking for a midrange PSU which offers good electrical performance and low noise operation need look no further than the Silencer Mk 3.”

“Everything is well within specification…clearly this power supply has superior +12V regulation. We did meet our 80 Plus Bronze expectations. All 105°C rated Chemi-Con capacitors are used, the unit is rated to run continuously up to 50°C and ran perfectly fine under our own 37°C conditions. Given the fact that this is a semi-modular power supply and is 80 Plus Bronze, that’s a pretty decent price. Build quality was really good and this unit will easily out last the 5 year warranty provided by OCZ. Ripple’s within spec and what we saw during the rise-time is within spec and would have no ill effect on your computer.”

“The claim that this unit can deliver its full power even at 50°C ambient is absolutely true since we conducted the full load test at 50.4°C and the PSU worked flawlessly. Finally at low-middle loads even at high ambient the fan is almost inaudible but at higher loads it makes its presence well felt. Such a price is very good for a modular 600W unit of this performance which is manufactured by Seasonic and uses quality components like Japan caps. Overall the PC Power & Cooling MK3S600 performed well and managed to work flawlessly even at very high ambient temperatures registering at the same time good efficiency (for its 80 PLUS certification) and ultra low ripple on all rails. The semi-modular design, the flat modular cables and the five year warranty are the cherry on top.”

Voltage regulation was excellent, with all positive voltages closer to their nominal values than necessary. The PC Power & Cooling Silencer Mk III 600 W provided extremely low ripple and noise levels during all tests. The new PC Power & Cooling Silencer Mk III 600 W is a very good unit. This unit is being sold for USD 90, but if you live in the United States, you can get a USD 20 mail-in rebate, making its final price USD 70, which is an outstanding price for this power supply.

“The Silencer MK III 600W has achieved the high standards we would expect from a PC Power & Cooling product, which in itself is no mean feat. The internal design is also exemplary with a high level of attention to detail and we always like to see 105c rated Chemi Con capacitors incorporated into a design.Noise suppression is fantastic. The power supply held load regulation well and cross load stability was not a problem. Efficiency is also without question, achieving almost 87 percent efficiency at 50 percent load, very impressive for an 80 Plus Bronze rated unit.”
