Conclusion

With the Silencer MK III 750 Watt, OCZ presents a very good and solid power supply. 91.30 Percent efficiency at 50 Percent load is a very good value and as a result thermal dissipation power is low. This implicates a noise level which is low too because there isn't much heat to be removed by a fan. Once put in silent mode the fan is being turned off as long as the load stays below 50 percent, which is remarkable. Always practical is a cable management and furthermore we like the number of integrated cables. There really is enough in the delivery to make any enthusiast happy.

A cable management is always a good thing because of the simple reason that it allows users to only connect cables they really need. Therefore a system can be wired as neatly as possible. Unfrotunately OCZ chose to equip this PSU with male connectors on the PSUs side. This means that if you were to forget to put the plastic caps back on the connectors you can easily shorten the PSU.
With four molex connectors and twelve SATA connectors it shouldn't be a problem to wire a high-end system. Also the fact that you can natively connect a two-way-SLI/Crossfire setup shows the Silencer MK III's preferred field of application. There is even plenty of power left to overclock a setup which uses three cards.

If we look at the performance values, the OCZ Silencer MK III 750 Watt shows very good stability under load conditions. If we look at average deviations, we see that the results at 3.3 Volt and 5 Volt with 20 and 50 percent load deaviate a bit more than other PSUs in our list. Never the less there is nothing to worry about since the values are still perfectly within the ATX specs. Convincing that's what the efficiency is.
