be quiet! claims to be Germany’s number one brand in PC power supplies and they are continuing to expand sales into North American markets. In this review we will be taking a detailed look at the new be quiet! Straight Power 10 800W power supply with Cable Management. There are four power supplies in the Straight Power 10 CM Series, which include 500W, 600W, 700W, and 800W models.

be quiet! designed the Straight Power 10 CM Series to provide high efficiency with minimal noise for systems that demand whisper-quiet operation without compromising on power quality. In addition to the Straight Power 10 Series, be quiet! offers a full range of power supplies in ATX, SFX, and TFX form factors.

All of the new Straight Power 10 Cable Management Series power supplies are semi-modular (all cables are modular except for the fixed 24-pin ATX cable). Along with 80 Plus Gold certified high efficiency, the Straight Power 10 800W modular power supply has been designed for quiet operation. It uses be quiet!’s latest SilentWings3 135mm fan for virtually silent operation (at low to mid power levels). The fan speed starts out very slow and remains slow and quiet through mid power levels.

PSU Testing Methodology

Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise DC load on the PSU under test.  Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage.  Our current suite of tests includes:

•    DC Load Regulation
•    AC Ripple and Noise
•    Efficiency
•    Differential Temperature
•    Noise

The be quiet! Straight Power 10 800W CM power supply was evaluated on both features and performance.  A full range of equipment was used to test the power supply under controlled load conditions.  

•    (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
•    (4) CSI3711A Programmable DC load (+12V)
•    (3) 218W Precision resistor load bank (+12V)
•    Switchable precision resistor load bank (-12V and +5VSB)
•    Agilent 34401A digital multimeter (Accuracy ±0.0035% vDC)
•    Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
•    DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
•    Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
•    Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)

The following cables/connectors were used to connect the SP 10 800W CM to the PCPerspective power supply test equipment.
•    (1) 20+4 pin ATX
•    (1) 8-pin EPS/ATX12V
•    (4) 6-pin PCI-E
•    (2) SATA
•    (2) Molex

Lee at least now people got a matching PSU for the Be Quiet "case, heat sink, and fans".

>>
To simulate real world operation, some of the warm exhaust air from the PSU under test is recirculated back to the intake through a passive air duct, which allows the PSU air inlet temperature to increase with load, just like it would in a real PC.

This is not true in many cases, such as when the PSU is at the bottom of the case and when the case uses a rotated design like the Silverstone FT02 and FT05.

Yes, you are correct in many instances. Maybe a better wording would be "to simulate worst case, real world operation...
