PC Power & Cooling, which is part of OCZ, released the third generation of its Silencer series a few weeks ago. The first new model to appear was a power supply with a capacity of 1200 watts. The Silencer Mk III 1200W is a true high-end PSU, which is apparent from the high capacity, its relatively high price of £229 and the quality finish. We compared it to other recent high-end 1200W power supplies, including the Corsair AX1200i and the Enermax Platimax 1200W.
The Silencer Mk III 1200W follows the single-rail principle. It can supply a maximum of 99.5 ampère on the 12 V rail, which is almost the entire maximum capacity. The 5V and 3.3V rails can supply a maximum of 20A. The PSU is 80 Plus Platinum certified, and with half its capacity OCZ promises an efficiency of at least 92 percent.
It's a modular power supply, so you only have to use the connectors you actually need. We mentioned the high-quality finish, as the modular cables have a type of XLR-like connectors that you screw onto the PSU. It not only looks very nice, it is a solid construction. You only get 4 molex connectors, but 12x SATA and 6x 6/8-pin PEG power connectors. The cables are long enough, and all are sleeved. OCZ even includes a little case for storing the unused cables.
Another unique feature of this PSU is the white colour of the housing. The 14 cm fan is black, and the speed depends on the load. It remains off completely until the load reaches about 40 percent, meaning it's a semi-passive PSU.
The average price of £229 is not cheap, but compared to the competition it's not too bad. The other two Platinum 1200W we tested, the Corsair AX1200i and the Enermax Platimax 1200W, both cost around £250. These are the PSUs we will be comparing the Silencer Mk III 1200W to.
The specifications of the Silencer Mk III 1200W are good, but we're more interested to the real-life performance.
