be quiet! released the Straight Power 11 series with many interesting features
SILENT WINGS 3 FAN
The high-end Silent Wings 3 fan delivers best-of-class airflow yet produces very little noise. This is thanks to its unique, optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor that largely eliminates operational noise, has a super-long life and minimal power consumption.
FUNNEL-SHAPED FAN OPENING
The fan inlet of the Straight Power 11 650W is funnel-shaped. It causes an increased throughput of air which benefits to a higher cooling performance.
WIRE-FREE DESIGN INSIDE THE PSU
The Straight Power 11 650W is wire-free on the DC side inside the PSU body. This results in improved cooling airflow and less signal disturbance, simply because of a lack of wiring, and ultimately pushes the lifetimes of the components to a maximum.
Thanks to the modular cables, all cables that serve no purpose in the system are left out. For this reason, systems always appear very tidy. At the same time installation is performed much more conveniently. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures prevail inside the case.
80 PLUS® GOLD CERTIFIED
Straight Power 11 650W is certified with 80 PLUS Gold efficiency, reaching up to 93%. This gives less power consumption and a cooler and quieter operation. Truly a benefit for any system.
The use of LLC and Synchronous Rectifier (SR) provides very stable operation and enhanced voltage regulation. The PSU is equipped with DC-to-DC conversion for tight voltage regulation even under heavy cross-loading conditions. This ensures reliable operation with the next generation of processors and graphics cards.
JAPANESE 105° CAPACITORS
Only the best components are used in Straight Power 11 650W. That is why we have built only high-quality Japanese capacitors into the PSU chassis. They are rated to 105°C, ensuring stability, reliability and a long operating life.
Passing to the retail package...You can find the product around 109 Euro (including VAT), making an affordable product for the 650Watt category, at least compared with other similar rated products we checked. The retail package is well designed and includes at the front all the needed information for users.
Everything is well packaged
There is a printed manual inside and the main PSU is wrapped around plastic bubble bag.
Several modular cables are included. All cables have a round braided design. Of course mounting screws are included as well as several zip ties for managing all cables.
The power supply has a matte black finish like most of the tested power supplies we have recently have seen at our labs. All the edges are not sharp, so you can handle it without any worries. The rear has a honeycomb design, that helps lower PSU's internal temperature, since drives the produced hot air out of the case.
At the back we can find the power ratings of the product
The power supply is fully modular for less cabling inside the case
There is a huge 135mm fan with minimal noise levels
and here how is looks like after inserting the needed cables for operating a new PC build
The PSU has the typical dimensions for this category and should be able to be used with all categories of cases, except from small desktop or very basic tower designs.
The power supply has four +12V rails with two rails getting 18Amps, while the other two 22Amps output. The +5V boosts 24A, while the +3.3V rail 24A. Lastly, the +5VSB gives another 3A. For sure we would like to had a single 12V rail that would be better for sudden high load scenarios.
Unpacking the various connectors we find various cables with good overall length that can be used in all modern PC cases, you won’t have problems even with big cases:
ATX 24 pin & 20 pin compatible
EPS/ATX12V 4+4 pin
PCI-E 6+2 pin
4 pin Peripheral
