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 recent PC instances, particularly these tailor-made for high-performance parts. Nonetheless, although its dimensions are typical of high-performance merchandise, it could possibly 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 selection for a product primarily aiming to compete when it comes to worth. The unit incorporates a barely textured black end, with the corporate’s brand subtly embossed on the correct facet of the chassis for a contact of magnificence. The fan finger guard is a smooth, stand-alone parallel wire design. An informational sticker detailing the PSU’s certifications and specs is neatly positioned on the left facet, 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 many of the unit’s entrance facet, every marked with a transparent white legend for simple 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 models 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 provided 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 accountable for cooling a 650W unit.

The Pure Energy 12 M 650W PSU is manufactured by HEC/Compucase, an OEM identified for producing energy provide models throughout varied segments of the market. Whereas HEC/Compucase might not be as well known among the many top-tier PSU suppliers, it is without doubt one of the oldest and most skilled corporations within the area of PC energy provides, with their popularity for high quality and reliability standing agency throughout the business.

The design of the Pure Energy 12 M 650W employs established, dependable topologies, reflecting a deal with delivering worth and dependability. The PSU’s filtering stage, situated on the entry level of the AC receptacle, consists of 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 facet, 4 Onsemi 5C430N transistors on a vertical daughterboard are liable for producing the 12V line, whereas the three.3V and 5V traces 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 facet capacitors, a mix of Teapo and Nippon Chemi-Con, supply a steadiness between cost-efficiency and reliability. This part choice displays a strategic strategy to sustaining high-quality requirements whereas additionally contemplating manufacturing prices.
