PC Power & Cooling Mk III Silencer 750 review

Certification

So, OCZ offers a 80+ Gold certification, tested by the 80PLUS organization (the people that certify and test efficiency). We already explained a little what that literally means. But what does such a certification entail?

Well, we have standard, bronze, silver, gold, and platinum certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Gold is more efficient than your average PSU unit. Below you'll find a table that shows what efficiency levels a PSU has to achieve at a given load to make the grade for a specific certification level.

The Mk III power 750W supplies are certified by the 80PLUS organization to deliver a 90% energy efficiency at 50% load and still 87% efficiency when your PC idles. The product complies with the ErP (Energy Related Product) directive to ensure less than 1W of power is used in passive standby and off modes. We'll test that manually later on in the article. First have a peek at its impressive Wattage table:

That's heavy duty right there at ya ... the single +12V rail pushes 62 Amps x 12V = 744 Watt alone on that single rail, tied to it are 4x 6+2 Pin PCI-E connectors(!)  But let's have a peek at the more common features:

•  750W Power Output with Single Strong 12V Rail
  The PC Power and Cooling PPCMK3S1200 power supply delivers continuous750W @ 50°C of safe, reliable output for your computer systems. One single strong +12V rail with 2 x 4+4-pin CPU power connectors and 4x 6+2-Pin PCIe connectors can juice up your high-end CPU and even multiple graphics cards.
• 80 PLUS Gold Certified
  The 80 PLUS Gold certified power supply provides ultra-high power efficiency, saving your money on your electrical bill, reducing heat in your computer's system and prolonging its life.
