80 Plus Gold: 92% Efficiency

Power Supplies - The heart of every computer. Often overlooked and not given much thought when purchased, the power supply is one of the most important parts of your PC. Overclockers UK know that buying a reliable and good quality PSU is the key to a stable PC, which is why we offer a vast range of units from leading manufacturers such as SuperFlower, Seasonic, Cougar, EVGA, Corsair and be quiet!

80 Plus certification was initially introduced in America, but is now a global standard for the efficiency of power supplies. As time has gone on, Ecova has introduced various label standards of efficiency to their website in order to grade power supplies accordingly. These are tested either by 115v or 230v EU standards, with the following minimum efficiencies required: -

80 Plus - 115V - 80%, 80%, 80% / 230V - 82%, 85%, 82% (at 20/50/100% load)

80 Plus Bronze - 115V - 82%, 85%, 82% / 230V - 85%, 88%, 85% (at 20/50/100% load)

80 Plus Silver - 115V - 85%, 88%, 85% / 230V - 87%, 90%, 87% (at 20/50/100% load)

80 Plus Gold - 115V - 87%, 90%, 87% / 230V - 90%, 92%, 89% (at 20/50/100% load)

80 Plus Platinum - 115V - 90%, 92%, 89% / 230V - 92%, 94%, 90% (at 20/50/100% load)

80 Plus Titanium - 115V - 90%, 92%, 94%, 90% / 230V - 90%, 94%, 96%, 90% (at 10/20/50/100% load)

Basically, the higher the label, the better the efficiency.

80 Plus Gold power supplies are the most popular choice amongst enthusiasts for their combination of high efficiency and price vs performance. OcUK have one of the largest ranges of 80 Plus Gold power supplies on the market, and offer such award winning units such as the SuperFlower Leadex and the be quiet! Straight Power 10 series.

All Gold rated PSU's exceed the requirements for the efficiency of complete machines according to the EU Regulation no. 617/2013 and should be used in all pre-built systems sold in the EU after the 1st July 2014.
