    • Power to the people
Style: Pure Power 11 FM Gold Size: 650W
Quiet power supply that keeps my system going.

    • As Advertised
Style: Pure Power 11 FM Gold Size: 650W
Pros: Lives up to the name, extreme quiet operation, almost inaudible Cons: The 8-pin motherboard connector could have been 1-2 inches longer. In my Corsair 275R case it is stretched so tight I could barely seat the PSU

    • Very quiet under load, efficient. Cables are malleable and black, great value.
Style: Pure Power 11 Gold Size: 500W
Just wish it was modular, otherwise, excellent, 10/10 for what it is. Reasonable price. Black cables, not tough. Connectors are a little tight once they're in but that's not too unusual.

    • The best 600w power supply on the market
Style: Pure Power 11 CM Gold Size: 600W
After years of using Corsair and EVGA power supplies and never being satisfied with the noise level even though they were always marketed as "ultra quiet" I stumbled upon Be Quiet, a brand that I was unfaimiler with at the time. I bought the power supply and low and behold, I heard nothing. after years of annoying little sounds that drove me absolutely nuts I was able to sleep peacefully at night knowing that when I turned on my computer in the morning I could drink some tea in peace without a constant annoyance in the back of my mind. as far as power supply things go it does what its supposed to, and it does it very well. the voltage is very efficient and the build quality is immaculate, not one complaint. Installing was a Breeze and the cables felt high quality and pretty malleable being able to navigate around the case well. When the GPU market goes back to normal I'm planning on pairing it with an RTX 3060 ti which should be more then acceptable. ... show more

    • Quiet doesn't sound so quiet - perpetual coil whine
Style: Pure Power 11 FM Gold Size: 750W
I bought the BN672 Pure Power 11 FM 750W PSU. It's modular which made building easier, and it's reliable, no functional issues so far. But I bought this PSU to hopefully keep any operation from the PSU silent. Even when web browsing, I can confirm there is a constant coil whine coming from the PSU. EDIT: I'd like to add context that my system is an OEM 5800 and I've used two GPUs, one at a time, a 6800 xt and 6900 xt. It is not recommended to use a 6900 xt with a 750w PSU though it MAY be usable, but coil whine started with the 6800 xt. It seems newer cards bring out the worst in older PSU's, like coil whine. ... show more

    • Still working well
Style: Pure Power 11 Gold Size: 600W
Used it for a mid system and it's working well without problems as far as I can tell. Quiet true to it's name. Black cables are a plus if you have a clear case window. Installed without issue, though lot's of spare cables to hide as it's not modular at all, but I knew this buying it. Well kinda there was a hiccup with the pictures early in the posting of this that I only realized after but it's not the end of the world for me as I have a psu shroud to hide the extra cables. For the $70 it was when I got it at the time, I'd say it's worth it. ... show more

    • Absolutely quiet, love it
Style: Pure Power 11 CM Gold Size: 600W
Bought this to replace my old Thermaltake psu. The whole world just goes silent. Can't hear any sounds coming from the psu and even the pc case fans sounds louder than it. I don't mind it's a semi modular build it's functional just as a full modular one. It doesn't runs hot and the temperature just stays moderate. If you're really into a quiet build for gaming pc, go for be quiet psu and cpu cooler. It will gareentee lower the noise to minimum that other brands can't compare. ... show more

    • Perfect for the price
Style: Pure Power 11 Gold Size: 500W
Not actually modular or semi-modular, but it's great, easy to install. Makes no noise even with high loads and perfectly powers my GTX 1660 and Intel Xeon processor.
