be quiet! Straight Power 11 Platinum 850W, fully modular, 80 PLUS Platinum, power supply

Upgraded processor from Ryzen 3600 > 5900X and have an ASUS TUF 3070 OC as the GPU. Had been using a Be Quiet 600W PSU with no problem but it was both only 80+ Bronze and power limiting. I like Corsair and the reviews looked good. Installation was a little bit tricky as the PSU is bigger than many other 1000W but not an issue. It came with 2 less cables than the manual stated. However, no matter how many checks on hardware and software, there was a significant power coil whine. I use a Corsair 275Q quiet case and want a quiet but powerful pc. The HX1000 was very much louder under 400-500W load than the 600W PSU. There was also a dreadful power coil whine that on researching, is quite common. Have replaced with a Be Quiet Straight Power 11 1000W and this is almost completely silent at idle and barely audible at full gaming. Really can't say more than if you want a quiet pc, these PSUs will do the trick.

The main thing that stands out to me with this PSU is the incredible build quality, the cables are built amazingly and come in mass! Easy to install, comes with screws too. Barely any noise at all. Would recommend this to anyone looking for an efficient and reliable PSU.

Couldn’t be happier. A great upgrade to my old BeQuiet PSU from 2014. Again this one is super silent and, best of all, absolutely zero coil whine unlike many of the big brands. Throughly recommend BQ every time. Powers my RTX 30 and 12th gen setup brilliantly.

My new 1000w Gigabyte PSU was making a really annoying coil whine noise when scrolling/doing my work. I changed to this LLC 1200w BeQuiet 11 Straight Power PSU and the noise has gone.

Very happy

The ATX cables are definitely on the short side, which given that 1000w supplies are going to be used in high end systems is a little disappointing. I built in a Meshify 2 CL and the ATX cables in particular were too short to go behind the motherboard and back out, instead requiring that I take the ugly route through the front side. If you want to use this in a larger case and properly cable manage, consider ATX and 8 pin extension cables.

The headline says it all

So far so good I did have a 650w ver which is still working fine I just wanted 100 more watt to secure the 3000 series nvidia build

Diseño, calidad y ruido no audible. Todo perfecto.

Always read good review about be quiet but as a first product to actually try.. I am not so impressed. The cables included are not the best quality. Although the product quality is good but the motherboard ATX 24pin plastic lock was loose which is disappointing.. it did fit in my mobo though without any issue.. for mining rig I wanted something powerful and quiet so this good but I think I could have got better option for less price

Acquistato ad un ottimo prezzo (96,55€) forse perché è uscito il modello aggiornato BN641, dal quale tuttavia non presenta differenze rilevanti. Venduto e spedito da Amazon è arrivato il giorno successivo all'ordine. Molto silenzioso ed efficiente, dotazione di cavi completa. Difetti: cavi un po' rigidi e solo 4 piccole fascette fermacavo in plastica, un alimentatore di questa qualità meriterebbe in dotazione fascette in velcro. Non considero un difetto invece il "tic" del relè solo allo spegnimento del computer (all'accensione non si sente).

después de iniciar mi descubrimiento con las fuentes bequiet hace muchísimos años cuando una gráfica AGP no podía ser alimentada con la fuente original, se ha vuelto una marca de confianza para mí. entre el trabajo y casa podré tener funcionando ahora mismo 8 fuentes Bequiet y sin problemas porque aunque en los test y reviews siempre Corsair sale mejor parada, en cuestiones técnicas o estabilidad de voltajes, etc... el que compra BeQuiet lo hace por un motivo fundamental, que es el ruido (o mejor la ausencia de él) en este caso tenemos una fuente que monta el mejor ventilador de mercado en términos de ruido-rendimiento (junto con los noctua) y eso es fundamental. claro que puedes pensar que otras fuentes híbridas no encienden el ventilador hasta X, pero yo pienso que es mejor siempre tener una refrigeración aunque sea a bajas vueltas. por otro lado, el otro lado del ruido, también cumplen siempre, y es el maldito CoilWhine, que te puede venir de la fuente o de su emparejado con otros componentes (habitualmente gráficas) y como no, está fuente tampoco lo tiene. por lo que podemos decir que es realmente una tumba. a nivel de potencia bla bla bla, pues 750w dan para cualquier sistema monogpu y no da ningún problema con ello (yo alimento una 980 y un intel 4930k a 4.4GHZ, por lo que es bastante tragón), como pienso que cualquier fuente de cierto prestigio y a partir de certificación Gold debe hacer. resumiendo, si quieres asegurar el silencio es una compra perfecta

Un alimentation de très bonne qualité, même l'emballage respire la qualité. Inaudible une fois branchée dans une tour Antec P101 que j'utilise comme serveur NAS fait maison tournant 24/24 d'où ma recherche d'économie d'énergie (Alimentation Platinium) et de silence.
