be quiet! Pure Power 12 M 850W power supply, 80 PLUS Gold efficiency, ATX 3.1 PSU with full support for PCIe 5.1 GPUs, exceptionally silent 120mm be quiet! fan, 2 strong 12V-rails, modular cables

The be quiet! Pure Power 12 M 850W is an outstanding power supply that delivers on every front. It’s whisper-quiet, even under load, thanks to the high-quality 120mm be quiet! fan. If you're building a silent or performance-focused PC, this PSU is absolutely ideal. It comes with full ATX 3.1 and PCIe 5.1 support, so it's perfect for powering the latest GPUs, including those with 12VHPWR connectors. Having two strong 12V rails means stable power delivery across demanding components, and I’ve had zero issues with voltage drops or coil whine. The modular cables are a massive bonus—easy to route and help keep the build super clean. All the cables feel premium and flexible, which makes installation a breeze. Efficiency is top-notch too, with 80 PLUS Gold certification ensuring power is used efficiently and temperatures are kept low. Overall, it’s a premium-quality PSU that’s quiet, reliable, and fully equipped for current and next-gen hardware. If you're building a high-end system and want peace of mind, this is a fantastic choice. Highly recommended!

I often use bequiet! PSUs in my computer builds. I've always found them to be reasonably priced, quiet and reliable. This unit, after about 9 months, is not changing my impression of the brand. I will almost certainly choose another be quiet! PSU next time I need to build a computer.

Very quiet. Modular with all the cables you need. If being nit picky the place of the ports could be placed better.

Item's great and works as it was supposed to.

Very quiet PSU I hate a noisy computer so was looking for the best product that will keep my pc quiet even under heavy loads. 100% recommended! Had my brother purchase one too as it is just amazing!

Excellent. I blamed all my pc problems on everything else apart from my PSU. I was running a 700 watt bronze cheap PSU and wondered why I was having problems. It's worth paying a little extra for a smooth running pc. Only issue is the cable connectors are a bit annoying. Greet otherwise

first time buying a be quiet psu (I normally buy the corsair SF series) and honestly very impressed with its performance and near silent, was very easy to install, cables are very well made, my only complaint is the motherboard cable is a bit short for taller cases such as the lian li sup01 case, the motherboard cable just about reach's but very little wiggle room so that could be improved and is something to be aware of if you have a taller case. comes fully equipped with 12VHPWR for those with a RTX series card making it future proof for high powered GPU's, would highly recommend be quiet psu with the caveat of the motherboard cable issue.

It's in the name really but bequiet! PSUs are very quiet. This one doesn't have a passive mode but that's not an issue as the fan runs whisper quiet and can't be heard over the GPU and case fans anyway. Handles intermittent loads and spikes well and that's about all I can say after a week of use.

Terrible pas de bruit ect.

Ottimo! Volevo un alimentatore silenzioso per un PC da tenere in salotto. Ho sostituito il mio vecchio con questo. ATX 3.1, ottimo cavo 12VHPWR. Stabile. Nessun problema di alimentazione sulle 50xx

Be Quiet, fiyat performans değerinin üstünde bir kaliteye sahip. Tercih ederseniz üzülmezsiniz.

Es una fuente que cumple con todo lo que una fuente moderna debe de tener. Eficiente, con certificación 80 Plus Gold (93,2 %), con conversores DC-DC en sistema de doble rail. Es modular, con lo que conectas sólo los cables que necesitas, liberando mucho espacio en la caja del pc. Es muy silenciosa. Si por algo es conocida Be Quiet!, es por lo silenciosos que son sus fuentes y ventiladores y esta fuente, no es una excepción. Es muy silenciosa, no se oye su ventilador de 120 mm, es una tumba. No en vano, el fabricante anuncia un ruído de 9,5 dB con el 50 % de la carga, y 25,7 dB con el 100 % de la carga, unos datos impresionantes. Incluye el estándar ATX 3.0 y PCIe 5.0, o sea que soporta picos de carga superiores a los 850W y trae el conector 12VHPWR que usan las tarjetas gráficas Nvidia RTX 4000 y que soporta hasta 600W en dicho cable. Además, incluye 2 cables con 2 conectores PCIe 6+2 pin (2 por cable) para conectar gráficas con el conector estándar. Cuenta con todas las protecciones actuales como son: OCP, OVP, OPP, OTP, SCP, SIP y UVP. La fuente tiene unas dimensiones de 150 x 86 x 160 mm. Una cosa a tener en cuenta es que los cables son tirando a cortos. Si la vas a instalar en una caja de tamaño medio y pequeño, no es un problema. En mi caso la he instalado en una caja de tamaño medio como es la Fractal Design Torrent Compact, y algún cable me llega justo y no sobra, lo que está muy bien, pero en una caja grande puedes tener problemas. En resumen, si tenemos en cuenta que es una de las fuentes más baratas con el estándar ATX 3.0 y PCIe 5.0, es de las más silenciosas y le sumamos la calidad y los 10 años de garantía que le da Be Quiet!, no puedo dejar de recomendarla.

Placa base B850 Tomahawk y gráfica Gigabyte 5080, va perfecta, no suena nada y trae justo las conexiones necesarias.
