PC Power & Cooling Silencer MK III 750W Review

The PC Power & Cooling Silencer MK III 750W is unquestionably an excellent power supply which will reinforce the brand name within the enthusiast sector. The bright white appearance may not suit everyone but there is no doubt that the build quality is deserving of some praise.

The new XLR style connectors are a fantastic feature which really improve on the plastic clip attachment system incorporated by competitors. The snug fit will ensure the best connection possible and they will be impossible to dislodge accidentally.

Technically, the PC Power & Cooling Silencer MK III 750W is a proficient design which exhibits no real weakness. It is true that flagship products from Corsair and Seasonic deliver higher efficiency readings and better ripple suppression, but these are currently the best on the market.

Load regulation from the MK III 750W is very good, and the unit passed our cross loading test without a hitch. We managed to get over 820W out of it before the protection circuitry would shut it down.

The large fan manages to emit very low noise, even when loaded heavily above 500W. This power supply may be overkill for a media center but the passive fan profiling means it is ideal for noise critical environments.

We have no UK pricing yet for this power supply, but OCZ informed us that the 850W unit will cost $169.99 and the 750W reviewed today $149.99. It is difficult to accurately guess how this will translate between America and Britain, but the Seasonic X Series 750W unit is currently available for £124.99 inc vat so the MK III 750W will need to be closely matched if OCZ want to claim sales.

We can certainly recommend the PC Power & Cooling Silencer MK III 750W, but it does face some stiff competition from the likes of Seasonic (X Series 750W) and Corsair (AX760 & AX760i).


  • solid technical design.
  • XLR modular connectors are a move forward.
  • high efficiency.
  • good ripple suppression.
  • quiet.
  • 7 year warranty.


  • facing a lot of competition from the market leaders.

Kitguru says: This unit deserves to sell well, we just hope OCZ get the pricing right.

Rating: 8.5.

    Nice looking PSU, connector idea is good, didn’t hiper use those xlr style connectors before?

    I think the white is cool, not many others do that paint work. I would think it might cost a lot when it hits here tho, going on US pricing.

    Can you peel the black label off the side? I have one of the corsair 600T cases in white and I’ve been thinking about changing to a slightly more powerful and more efficient power supply for a while and this would look great in my case!!

    PS My current power supply is a hiper although its not a modular power supply the kettle lead has one of the xlr connections on it to enable a swap from UK to european style plugs
