wonderful
The be quiet! BN517 Straight Power 12 is an exceptional PSU for high-performance systems. With a 1200W output and 80 Plus Platinum efficiency, it easily powers my gaming rig and ensures minimal energy wastage. The modular design is a huge bonus, making cable management clean and hassle-free.What stands out the most is how quiet it is, even under heavy loads. True to its name, the PSU runs almost silently, which is perfect for anyone who values a quiet workspace or gaming environment. The ATX 3.0 support also ensures compatibility with the latest components, making it future-proof for upcoming builds.Build quality is top-notch, and the inclusion of premium cables adds to the overall value. I couldnât be happier with this purchaseâit’s a solid investment for enthusiasts or professionals looking for reliability and performance.

Excellent High Quality Power Supply
I needed this item when my NZXT PSU failed after only 10 months of regular use. I was in the middle of very important work related projects and needed a replacement right away. Amazon same day delivery and the availability of this high end product saved the day. This PSU is a highly rated and fairly priced item that lives up to its name, Be Quiet!, by operating in absolute silence while delivering lots of power. The included cables are also high quality with sleeves and plenty of them.

Another great Be Quiet product
Definitely gotten the job done. As a Corsair fan, I typically try to stick with them for various PC parts, however, after identifying that my Corsair PSU was not getting the job done and causing my pc to crash, I ended up switching to this beauty.For a 1200w PSU, its actually super quiet, haven’t had any PC crashes, the mesh sleeves feel amazing, I think the only downside I can say is that the power cables for the CPU are slightly too short, so they became a pain for cable organization, also came super close to not even reaching the plugs on the motherboard (normal ATX case with motherboard CPU power in the top left corner)

Solid PSU
Upgraded my PC and decided to go with this PSU and I am very happy.I have not heard this PSU at all and I worried its not working lol. Its so quiet, no rgb, just providing solid raw power to my 14700k & RTX 3090. It came with all the cables needed and extra. Truly happy with this PSU and great brand to stand behind.

The best power supply for a test bench HANDS DOWN!
I have owned a few different brand PSU’s over the last 20 or so years and always tended to go with Seasonic for there longevity. My last one went strong for about 8 years before starting to lose 5v stability recently. So I figured I would just go Seasonic again but decided to do a little shopping around first. I had always heard good things about be quiet CPU heatsinks and fans being very reliable and super quiet but had never owned anything from them. So after watching some reviews and reading a bunch about them I decided to give one a go. I have a Praxis Wetbench (PC test bench) that has nothing to block any fan noise which is always a challenge when dealing with a test bench config. I have my system filly liquid cooled and some very quiet fans on my radiator but my Seasonic PSU was always the loudest part of my setup. To the point where when at full load benchmarking or gaming it would sound like a hair dryer and was always a bit annoying. Over the years I guess I just got used to it and debt with it. But with this be queit let me tell you.. THIS THING IS NEAR SILENT! Even when pushing it pretty hard it never gets louder them my radiator fans and they are very quiet. I cannot put into words how peaceful my office is now. Its wonderful! I cannot speak to be quiet’s longevity but I can definitely say its by far, the quietest PSU I have ever used and the build quality seems very good. Also come with very pliable sleeved cables. Much better then the flat black one you get with Corsair, Thermaltake, Coolermaster and multitude of other brands. Hoping for many years of use. Love it so far!

Works great! Small issue with cables
Great power supply, quiet, doesn’t make noise when under load (heavy gaming), looks like it’s built with quality. I’d say it’s worth the money, at least based on my experience so far.I have an issue with its cables (see photo) — they are all really long and firm, which might be a plus for some people, but particularly the GPU cables are causing problems for me: the 8-pin that goes into the graphics card supplemental power socket is very firm it goes at 0 degree angle w.r.t. the card which makes the cable stick out way past the left-side case wall border of the case and I can’t bend the cable to fit. I don’t usually close that wall, but even now I’m worried about pushing the case too hard against the desk and damaging my graphics card (imagine the lever against the PCI-e port, especially given how heavy the cards are by themselves…). Anyway, would be nice to engineer and include some sort of 90-deg plug option — I can’t even find one on Amazon so far..

Cheapest 1500W you can buy thatâs from a well known company. Wish it was PCIE 3.1. I am extremely worried about the 12V connectors melting â¦

Excelente precio y calidad

Esta claro que por el precio podrÃas comprar una psu con un poco mas de voltaje. Sin embargo, la marca be quiet se caracteriza por el desarrollo de buenas fuentes de poder y ahora que tienen la certificación platino sobre todo esta serie straight power 11 la hace muy atractiva y es totalmente modular. El nivel de ruido es muy silenciosa, aunque no tiene la tecnologÃa de zero fan mode, pareciera que lo tiene integrado el ventilador no se oye en lo absoluto. Respecto al 850w probablemente fue un poco de overkill ya que planeo meterle una 3080 y un ryzen 7 o 9 aun esperando la zen 3. pero tener un poco extra no hace daño y te deja espacio para futuras upgrades.Recomendada si quieres una alternativa a una corsair rmx (caracterizada por silenciosa) y con certificación platino.

La compré porque hice una mejora en mi computadora que requerirÃa más energÃa y va muy bien y sin ningún problema en el funcionamiento. La única dificultad encontrada fue que las barritas de metal de la parte del ventilador que fungen como “malla” se sienten no muy resistentes, en mi caso batallé 1 poco para meterla en mi gabinete ya que sentÃa que se podÃan romper; aparte, el switch para prenderla se siente distinto (por no decir que de menor calidad) que el de la PSU que tuve anteriormente ya que se siente algo “flojo”.

La utilizo para darle poder a mi PC con un i9-12900k y no he tenido ningún problema, es muy silenciosa. Próximamente veré cómo se desempeña añadiendo una RTX 3080 TI.Recomiendo que utilicen la herramienta de calculadora de fuente de poder que está en la misma página de be quiet! para que elijan la versión correcta.
