So I purchased this PSU 3-2024 and it has been rock solid for that whole time. Can not say enough about how well built this PSU is. I would recommend this to anyone needing a 1000 watt PSU. I have used it with 2 builds and have not had any issues at all with either system. 1st System AMD Ryzen 5800X 3D with MSI RTX 4070 Ti, 2nd System AMD Ryzen 9800X 3D with a Gigabyte RTX 5080. This PSU handled both system without issue. Great PSU, I know it is on the pricy side but well worth the peace of mind.

First time buying and using be quiet power supplies, i often have a hard time with a lot of power supply manufacturers due to any number of reasons i suspect it's due to my towns dirty power, put it behind a UPS (uninterruptible power supply) And you should be okay. So far as it stands, it's a little bigger then one would expect for an 850 using a o11 dynamic mid tower fits fine in the larger slot, can't place it in the smaller psu slot. the fan does not shut off, though it is quiet functions as intended no strange electrical smell or if so it's not noticeable.

Nothing good to say unfortunately. Have always liked this brand and I'm running one of the coolers in my system right now. To keep this brief, I was replacing a working corsair RM850e PSU in a working system. I had coil whine from the Corsair unit that was buzzing through a new speaker setup that I wanted to get rid of. I received one Be Quiet unit that was dead out of the box - couldn't even pass the paperclip test. Ordered a second one on Amazon while initiating the first return. The second unit arrived the very next day. Before even attempting to install it, I decided to test it first. Also failed the paperclip test and never once turned on. Both units were then tested with a multi meter, both were completely dead. The manufacturer did have very quick and polite customer support after the first failure. But two high end new units arriving DOA from a distributor like Amazon is completely unacceptable. Unless there is some kind recompense or public statement I will likely never buy another product from this company. I understand these things happen, but two in a row for a power supply, a product where reliability is the ONLY meaningful metric, is not easily forgiven. I ended up replacing the Corsair with a Seasonic. It worked on the very first try and have had no issues since.

Quiet and powerful, exactly what it needs to be. Plenty of connectors for all the internals making wire routing clean and efficient.

This is without a doubt the best power supply I have used in any of my PC builds to date. The ease of use, versatility, and power efficiency is everything I could’ve asked for. To start, the power supply comes fully modular as advertised, and also includes all the cables you may need for your setup including the Motherboard, CPU, PCIe, Molex/SATA, and 12Pin Power Cables. It also includes the wall power cable, overclocking jumper/case switch, plastic zip ties, Velcro-style cable ties, mounting screws, and thumb screws. Each of the cables connect securely to the power supply without issue, and each cable is covered in a black sleeve that keeps the cables tidy and sleek while still being easy to bend. My favorite part about this power supply is definitely the built-in 12Pin power connector and cable for newer Nvidia GPUs as it removes the need for having to use an adapter and makes the entire process more seamless while also looking better. The power supply also includes both standard mounting screws as well as thumb screws depending on your installation preference. The power supply also has clear labeling for where each cable needs to be connected, in addition to labels that signify which rails power the specific ports on the power supply itself. This power supply also comes with an “overclocking” jumper/case switch that when active will transform all the individual power rails into a single rail, if the need was to ever arise. In general use, the power supply runs silent and doesn’t make any noise. I haven’t heard the fans ever, and I couldn’t tell you if I have even managed to put a heavy enough load on it yet to make the fan engage. Yet, I am easily able to use the power supply to hand more power over to both my GPU and CPU without any problems which has helped me a lot in getting a slight performance boost out of my components. Regardless of what components you have, this power supply is more than enough to handle the majority of all PC builds. Overall, whether you’re looking for something to help you overclock your CPU or GPU power limits, or just want a really stable, solid and reliable power supply with lots of wattage to spare, then this is an excellent option. I highly recommend it!
