PSU be quiet! STRAIGHT POWER 10 600W CM: review and testing

The German company Listan GmbH & Co. KG, better known under the brand be quiet! is a leader in the European market of power supplies. And in other countries its products are very popular. Let’s learn the range of offered solutions. And this trend is typical for all lineups of power supplies, starting from cheap devices aimed at the mass user (a series of be quiet! PURE POWER) and to the top-level model designed for enthusiasts of computer equipment (series be quiet! DARK POWER PRO). 

However, in this review we want to talk about the "golden mean" - representative of the ruler be quiet! STRAIGHT POWER. In our opinion, they are the most balanced solution to the model number of the company and certainly appeal to many users.

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

It seems that this opinion is shared by the manufacturer, because this series includes just 8 solutions and covers a fairly large segment of the market of power supply from 400 to 800 W. Moreover, the customer can save money and buy a model with the traditional configuration of cables or spend a little more money and get the version with detachable cables. In the second case, in the name of the power supply has the prefix «CM» (Cable Management). One of such devices will be described in the review, to be more precise a 600 W model be quiet! STRAIGHT POWER 10 600W CM which is also titled as «be quiet! E10-CM-600W».

Scope of delivery of model be quiet! STRAIGHT POWER 600W CM 10 is as follows:

  • power cord;
  • set of modular cables;
  • installation screws;
  • cable holders;
  • manual.

Design

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

The first thing we paid attention is excellent quality of its building and attention to detail. No defects such as bad-treated panels, large gaps or bad braid were not noticed. The body is made of thick steel and is additionally painted in stylish black color.

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

A notable feature of this model is a non-standard fan mesh on the cover: the traditional grill is replaced by a series of metal rods. Note that this configuration does not affect the placement of the power supply inside the computer case. The front panel has a more familiar look as a perforated mesh with the power outlet and the button to turn off the power.

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

be quiet! E10-CM-600W is equipped with partially modular cables: cable to power the motherboard is put directly from the device, while the rest cables are detachable. As a result, the building process is greatly simplified and you can organize as hidden cable management.

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

On the rear panel you can find seven connectors, which have the following purpose:

  • one 10-pin («12V P8») - for an extra CPU power;
  • four 5-pin («Drives») - for connecting peripherals;
  • two 12-pin (“PCIe 1 PCIe and 2”) - to power graphics cards.

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

All cables including detachable have a nylon braid. In comparison with similar strips as they are more rigid, therefore the system building in a compact package can be difficult and require more time, and to use various holders and clamps. Under standard conditions you won’t face with any difficulties.

The main power connectors are presented by detachable 20+4-pin ATX and 4+4-pin ATX12V. We were pleasantly surprised by the number of PCIe connectors to connect video cards - they are 4 pieces, all in the 6+2-pin version. In other words, be quiet! 10 STRAIGHT POWER 600W CM could theoretically be used as a part of gaming computer with two top-end graphics cards.

By the way, the configuration of cables for connecting peripherals also provided only good impressions. There are a lot of SATA and PATA connectors. In most cases only one cable is enough to connect the power supply to the drives and system fan.

Now let's take a closer look to the technical features of the model be quiet! E10-CM-600W. Its rated capacity is 600 W, and the peak according to the official website can reach 670 W. +12V rail is designed for relatively large load of 576 W, which corresponds to approximately 96% of the total power. However, it is divided into four lines - two 18 and two 20-ampere. In our opinion, it is more appropriate to use a standard chart with a powerful dedicated +12V rail. Rails +3.3V and +5V have a maximum total power of 140 W. In addition, each can withstand current up to 24 A. It is quite enough to power drives and other peripherals.

Model be quiet! 10 STRAIGHT POWER 600W CM complies with standard 80 PLUS Gold. According to its requirements, the efficiency of the power supply for loads of 20%, 50% and 100% of the nominal power must not fall below 88%, 92% and 88% respectively (for supply voltage 230 V).

Also note a wide input voltage range (100 – 240 V), which eliminates the external voltage regulators in an unstable power supply.

Internal device  

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

In order to cool the internal components there is a 135mm 7-blade fan be quiet! SILENT WINGS BQ-SIW3-13525-HF based on the fluid dynamic bearing (FDB). Its maximum speed is 1500 rpm, which should provide a minimum level of noise under the entire load range. Thus it has a fairly high efficiency indicating the power of 6.72 W. Thus according to the combination of characteristics it is one of the best fans that we met in the power supply.

OEM-manufacturer of platform that formed the basis of the power supply be quiet! 10 STRAIGHT POWER 600W CM is a famous company FSP. A feature of this circuitry is the type of converter: instead of the traditional high-end solution for the resonance circuit there is a single-ended set of a forward converter with active damper (Active Clamp Forward). Low-voltage part has a standard form of synchronous rectifier. However, they are some nuances. And now let’s go directly to detailed analysis.

Let’s start from a high-voltage part, which is mounted at the input of high-grade EMI-filter. This unit is responsible for smoothing high-frequency noise emitted by power supply, as well as bears the function of lightning protection. You won’t face with problems of elemental base (two X- and Y-four condenser, three chocks and varistor) and the isolation of the individual components of the filter.

The bridge for rectifying the input voltage is represented by a diode assembly, which is equipped with own radiator. Also here is the module Active Power Factor Correction (APFC) and high voltage capacitor (330 uF x 420 V). The manufacturer of the last is a Taiwanese company Teapo wiht average quality of products. Note that the capacitor belongs to a series of up to 105°C.

In the center of the board we found a source of standby power (+5Vsb) and the main converter. As mentioned above, it is a single-cycle forward converter with active damper (Active Clamp Forward). The main advantages of this topology are to reduce energy losses in case of transformer demagnetization and switching power switches, as well as a significant reduction in noise and interference. In addition, it makes it quite easy to arrange the direct management of synchronous keys on the secondary side (in the low-voltage side).

The disadvantages of this scheme include the need of use the PWM controller of a higher level, as well as complicated design of the transformer.

In order to rectify voltage +12V the manufacturer used more powerful transistors that respectively require more cooling. In this regard, they are positioned directly in the airflow of the fan, and have an additional aluminum radiator. It has a temperature sensor. It is important to note that the model be quiet! E10-CM-600W uses the principle of separate voltage stabilization.

According to the technical specifications, be quiet! STRAIGHT POWER 600W CM 10 has a whole series of protections (OVP, UVP, OPP, SCP, OCP, and OTP), including protection against overload and overheating. The node based on the chip Weltrend WT7579 and implemented on a separate printed circuit board.

be quiet! STRAIGHT POWER 10 600W CM (be quiet! E10-CM-600W)

The quality of board layout and assembly of components is very high: sagging of flux, soldering defects or other specific deficiencies are absent. And it is not surprising, since to the quality control of products produced by the German company.
