    • Quiet and stable
Style: 1200W Platinum ATX3.0
I've had this power supply for about 2 weeks now and so far so good, its stable and quiet. The atx 3.0 cable really tidies up the installation with only one cable going to the gpu. I've ran many games with no issues. I cant hear the power supply at all and the price is great. Would recommend as this is my first be quiet! product I've purchased. ... show more

    • Finally found it - a quiet power supply!
Style: 1200W Platinum ATX3.0
Review Image by Daru Junie Daru Junie
I was always bothered by the background noise from my power supply, especially at night. Discovered the be quiet! product and decided to give it a try. True to its name, it's incredibly quiet and provides stable power. The price is reasonable too. I won't have to worry about power issues when upgrading my computer in the future. ... show more

Style: 1000W Platinum ATX3.0
Easily fit in my NZXT H7. Very quiet, and way quiterer than a Corsair power supply. Also looks really cool and sleek when you unbox it.

Style: 1200W Platinum ATX3.0
if you are looking for a high wattage psu, look no further. This runs quiet and with great build quality.

    • Good so far!
Style: 1200W Platinum ATX3.0
Received today from Amazon and installed even though it wasn’t necessary as my seasonic 850W gold is still chugging along with my 4090. Really upgraded for the future of what’s next, the 1200 watts and ATX 3.0. All went as planned to this point, pulled out the old and installed the new while cleaning out the dust in the computer. Cables are nicer than the seasonic I had, all with mesh strains. Plenty of cables left for doing more if I want too. Plugged in the new hefty ATX 3.0 plug and everything fired back up without a hitch, put all my glass panels on the nicely cleaned up case and gamed away, will update if anything changes in the short term. Also, an added side note, mine was not made in China, it was made in Taiwan. ... show more

    • Quality, quiet!
Style: 1200W Platinum ATX3.0
It screams quality! Plenty of cabling options to power even the most demanding of computers. I came from a seasonic 660w platinum power supply on my old setup. I wanted to future proof, so upgraded to this atx 3.0 power supply.

    • Worked well for a year!
Style: 1000W Platinum
I didn't write a review when I first purchased this power supply nor when this power supply failed but I decided it was time to do so now. I purchased this power supply around Sep 2021 as part of several other items needed to rebuild my desktop. It installed fairly easily and it did come with plenty of connector cables. While it was in use the loudest parts of my computer were the cooling fans (still are). When it failed almost 11 months later. Unfortunately, I couldn't wait for the whole return/test/fail/replace scenario to play out and purchased another beQuiet power supply a day later (I had to get the 11 Platinum 1200w since it was the only one available for next day delivery). I finally got around to mailing off the broken supply in April 2023. I was notified April 21 that the facility had received my item. It is now May 2nd, 2023 and my replacement power supply was delivered today. I am pleased with the fairly quick turn around .. I just wish it was more like a broken cell phone .. they ship you the replacement FIRST and if you fail to send the broken item back they charge you for it. If I can find someone who wants to buy a new Straight Power 11 Platinum 1000W power supply I can offset some of my costs, since I don't expect the one in my computer to die (in over 20 years of building my computers I have only had 2 power supplies fail on me .. I have replaced many for bigger/better/newer reasons). ... show more
