Certification & Efficiency
Certification
Be Quiet! offers this PSU now as a Gold 80+ product 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 for manufacturers who use 80 Plus-certified PSUs.
Well, there is plenty to choose from, we have Standard, Bronze, Silver, Gold, Platinum and even Titanium certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is far more efficient than your regular unit. The Pure Power 11 power supplies are certified by the 80 PLUS organization to deliver an 92% energy efficiency at 50% load and 88% efficiency when your PC idles (at 230 Volts). The Pure Power 11 units have active PFC with a power factor up to 0.99 and are ErP compliant with a standby power drain below 0.1 watts.
These days we suggest you get at least a 500 Watt PSU for any mediocre PC, but considering your PC / PSU is the most efficient and energy friendly at half its load, it might be wise to get a higher rated power supply. The 300 Watt model tested is most efficient at 300 Watts, which is pretty much what a reasonably powerful PC with a high-end graphics card uses during a game of hefty fragging.
Pure Power stands for peerless dependability and best-in-class features at a competitive price point. Models with and without modular cables make Pure Power 11 extremely versatile in various applications. As a mainstream power supply, Pure Power 11 is best suited for silent PC configurations, powerful gaming- or workstations, and multi-GPU setups. Its predecessor, Pure Power 10, introduced DC-to-DC technology to the “essential” range of power supplies by be quiet!, improving crossload performance, and voltage regulation on the minor rails. Pure Power 11 keeps this proven topology, but upgrading a lot of passive and active components enables higher efficiency up to 92% with 80PLUS Gold certification. Higher efficiency leads to less heat generation and quieter operation. Compared to the predecessor, be quiet! also added an additional heatsink and removed the caps at the end of the 24-pin cable. Highlighted where applicable, this document lists all Pure Power 11 variants’ specifications, with and without cable management, and ranging from 300 to 700 watts models. Availability of different wattages may be subject to regional limitations.
