Energy efficiency certification

be quiet! offers the PP 11FM series PSUs as a Gold rated power supply as certified by the 80 PLUS 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, 80 Plus (trademarked 80 PLUS) is a voluntary certification program intended to promote efficient energy use in computer power supply units (PSUs). Launched in 2004 by Ecos Consulting, it certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load, and a power factor of 0.9 or greater at 100% load. That is, such PSUs will waste 20% or less electric energy as heat at the specified load levels, thus reducing electricity use and bills compared to less efficient PSUs. Sometimes, rebates are given to manufacturers who use 80 Plus-certified PSUs.

80 Plus test type	115 V internal non-redundant				230 V internal redundant
Percentage of rated load	10%	20%	50%	100%	10%	20%	50%	100%
80Plus		80%	80%	80%
80Plus Bronze		82%	85%	82%		81%	85%	81%
80Plus Silver		85%	88%	85%		85%	89%	85%
80Plus Gold		87%	90%	87%		88%	92%	88%
80Plus Platinum		90%	92%	89%		90%	94%	91%
80Plus Titanium	90%	92%	94%	90%	90%	94%	96%	91%

But there is plenty to choose from, we have standard 80plus, Bronze, Silver, Gold, Platinum, and even Titanium certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is more efficient than your regular unit. Today's tested PSU is certified by the 80 PLUS organization to deliver a 90% energy efficiency at 50% load (USA) and 92% efficiency when your PC at 230 Volts (EU) based on 50% load. These units have active PFC with a power factor up to 0.99 and obviously are ErP compliant with a standby power drain below 0.12 watts.

Power consumption for your PC has dropped over the years with all new technologies. These days with mainstream to high-end PC we recommend a 650 Watt PSU really, that is including the usage of a single high-end graphics card. We mention this because your PC / PSU is the most efficient and energy-friendly at half its load, sometimes it might even be wise to get a higher rated power supply. The model tested today is most efficient at 325 Watts, which is pretty much what a powerful mainstream PC with an average to high-end graphics card uses during a game of hefty fragging.
