This evaluate shines a highlight on the Be quiet! Pure Energy 12 M 650W PSU, a standout product in Be quiet!’s PSU assortment that illustrates the corporate’s perspective in the direction of product design. The Pure Energy 12 M collection is designed to supply reliable efficiency and quiet operation, catering to customers who demand steadiness of energy effectivity and acoustics with reliability and worth. This mannequin, specifically, strives to supply a compelling mix of efficiency and high quality, making it a gorgeous possibility for people in search of a PSU that aligns with the necessities of each entry-level and superior PC builds.

Packaging and Bundle

The Pure Energy 12 M 650W PSU arrived in an elegantly designed bundle, boasting a predominantly black colour theme accentuated by a picture of the PSU itself on the entrance. This sturdy cardboard packaging is enhanced with a nylon bag and foam inserts, providing distinctive safety for the unit throughout transit. Specs and detailed insights into the PSU’s efficiency are conveniently printed on the again of the field.

Consistent with Be quiet!’s streamlined strategy, the bundle contains solely the necessities for the PSU’s setup and use. Unboxing reveals a choice of mounting screws and an AC energy cable. Distinguishing itself with a totally modular configuration, the Pure Energy 12 M 650W permits for the detachment of each DC energy cable, together with the 24-pin ATX connector. 

The cables are uniformly black, from the connectors to the wires, and primarily undertake a flat, ribbon-style design for ease of cable administration, with the notable exceptions being the sleeved 24-pin ATX and the 12VHPWR cables, the latter particularly engineered to deal with as much as 450 Watts. Oddly sufficient, there are two CPU 12V connectors however one is restricted to a 4P connector solely.

Exterior Look

The Be quiet! Pure Energy 12 M 650W PSU is encased in a chassis that measures 86 mm × 150 mm × 160 mm (H × W × D), extending simply barely past the ATX customary specs. This design ensures the PSU suits seamlessly right into a broad array of contemporary PC instances, particularly these tailor-made for high-performance parts. Nonetheless, though its dimensions are typical of high-performance merchandise, it may very well be considerably shorter contemplating its cooling fan and energy output.

Be quiet! has positioned appreciable emphasis on the exterior design of the Pure Energy 12 M 650W, an odd alternative for a product primarily aiming to compete when it comes to worth. The unit contains a barely textured black end, with the corporate’s emblem subtly embossed on the appropriate aspect of the chassis for a contact of magnificence. The fan finger guard is a modern, stand-alone parallel wire design. An informational sticker detailing the PSU’s certifications and specs is neatly positioned on the left aspect, whereas the highest stays unadorned.

On the rear, a normal on/off change is situated adjoining to the AC energy receptacle, with a small ornamental sticker subsequent to them. The modular cable connectors occupy a lot of the unit’s entrance aspect, every marked with a transparent white legend for straightforward identification. Notably, the Pure Energy 12 M 650W features a 12VHPWR connector, showcasing its compliance with the ATX 3.0 specification, making it one of many only a few items which can be ATX 3.0 compliant with such a low energy output.

Inside Design

The Be quiet! Pure Energy 12 M 650W PSU is supplied with a cooling fan of their very own design and an unknown OEM to us, that includes an all-black design and a rifle bearing engine for sturdiness and effectivity. The PSU’s design permits for the inclusion of a bigger fan, but a 120 mm mannequin has been chosen to suit throughout the unit. This fan operates with a most pace of 1800 RPM, a good most pace for an 120 mm fan positioned in control of cooling a 650W unit.

The Pure Energy 12 M 650W PSU is manufactured by HEC/Compucase, an OEM identified for producing energy provide items throughout numerous segments of the market. Whereas HEC/Compucase might not be as well known among the many top-tier PSU suppliers, it is likely one of the oldest and most skilled firms within the discipline of PC energy provides, with their repute for high quality and reliability standing agency throughout the trade.

The design of the Pure Energy 12 M 650W employs established, dependable topologies, reflecting a give attention to delivering worth and dependability. The PSU’s filtering stage, situated on the entry level of the AC receptacle, contains three Y capacitors, two X capacitors, and two massive filtering inductors, adopted by a rectifying bridge hooked up to its devoted heatsink. The Energetic Energy Issue Correction (APFC) parts are positioned on a major heatsink throughout the sting of the PCB, that includes two APFC MOSFETs (Infineon 6R190P6) and one diode, alongside an encased filtering inductor and two Teapo capacitors (430 μF every).

For the first stage, the PSU employs a half-bridge LLC topology positioned on a big devoted heatsink, a extremely typical configuration in trendy mid-range PSUs. On the secondary aspect, 4 Onsemi 5C430N transistors on a vertical daughterboard are liable for producing the 12V line, whereas the three.3V and 5V strains are produced via DC-to-DC conversion circuits on one other daughterboard. This modular strategy to circuit design aids in sustaining a clear format.

The secondary aspect capacitors, a mixture of Teapo and Nippon Chemi-Con, provide a steadiness between cost-efficiency and reliability. This element choice displays a strategic strategy to sustaining high-quality requirements whereas additionally contemplating manufacturing prices.
