From a performance standpoint, the PC Power & Cooling SIlencer MK III 750W PSU is boasting a very good voltage regulation within its power spectrum along with very clean DC output. fan noise is low and the PSU's efficiency is high.
The device has been designed to power your SLI/CrossFire setups . Its massive single +12V (62A) rail has just so much power to handle multiple heavy duty graphics cards, considering that a graphics card uses 15A on average.
The PSU's $140 price is not as low as we would like, at least from the casual gamer's perspective. Considering that the Silencer MKIII 750W is facing the competition of other flagship products from Corsair and Seasonic - which are claimed to deliver top efficiencies and ripple suppression - it would be wise for OCZ to make this PSU more affordable.
