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.

Pure Power 11 FM: Mainstream power supply goes fully modular
At be quiet!, Pure Power stands for peerless dependability and a comprehensive feature set at a competitive price point. The Pure Power 11 FM series is no exception: by exclusively using fully modular instead of fixed cables, only cables that serve a purpose are installed, resulting in a smoother airflow, lower temperatures, and easier handling inside the case. Pure Power 11 FM comes equipped with black flat cables for all common connections and a black sleeved 20+4-pin ATX power cable. With two independent 12V rails for signal stability and up to four PCI-Express connectors (two for the 550W model), Pure Power 11 FM is fully suited for silent PC configurations, workstations or even gaming systems with a powerful graphics card.

80 PLUS Gold efficiency and improved topology
Pure Power 11 FM is 80 PLUS® Gold certified with an efficiency rating of up to 93.9 percent, a truly outstanding level for this PSU class. The most compelling benefits of this high efficiency are lower power consumption, lower electricity costs and a cooler, quieter operation. Pure Power 11 FM is equipped with LLC + SR + DC/DC technology for advanced stability and voltage regulation. Cooling is achieved with a silence-optimized 120mm be quiet! fan with airflow-optimized fan blades, enabling the extraordinarily silent operation that be quiet! is famous for. As usual, all modern protection circuits (including UVP, OVP, SCP, OPP, OCP, and OTP) are integrated. be quiet! offers a 5-year manufacturer’s warranty on Pure Power 11 FM.

SFX Power 3 and TFX Power 3: High performance in a compact form factor
The third iteration of these power supplies efficiently provides power for high-performance systems conforming to the space-saving SFX or TFX form factor. Despite their small dimensions, the SFX Power 3 and TFX Power 3 offer enough ports to power a modern mini-ITX system and a rock-solid 12V rail to support a dedicated graphics card. The SFX Power 3 series is available in 300W and 450W, offering 80 PLUS® Bronze efficiency. TFX Power 3 is available in two different 300W models: TFX Power 3 with 80 PLUS® Bronze efficiency and TFX Power 3 Gold with particularly high efficiency of up to 91.7 percent (80 PLUS® Gold). All of these new small form factors power supplies from be quiet! feature black cables for a contemporary look. A high-quality, temperature-controlled 80mm fan takes care of quiet and effective cooling, and modern protection circuits (including UVP, OVP, SCP, OPP, and OCP) are integrated, making this power supplies a great choice for office and web clients, HTPCs, or small gaming systems.
