be quiet! BN309 Straight Power 11 Platinum 1000W, fully modular, 80 PLUS Platinum, power supply, Black

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.

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.

It delivers on the brand name. Great product.

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 headline says it all

quite a beast and not cheap, but should cover all your present and future needs (4080 and more).

I've bought this 9 months ago for 210 pounds. All in all it has done a good job, but for that amount I was expecting a longer life.I've used it with a gaming pc. On average ~1 hour usage a day, some whole weeks with no usage at all.The customer support in Germany has been quite efficient in directing me, but announced that it will take ~10 working days from the day they receive the faulty PSU to dispatch a replacement.Considering the cost of shipping the PSU to Germany (£60), the time for it to get there, the time they take to evaluate and the time to get it back, I reckon in 1 month I could be using my PC again.If this was for work I would be forced to buy a new one and end up with 1 PSU that nobody will buy used.I would not recommend it.[Edit] I've got a parcel back from BeQuiet. It took 38 days from posting to getting a replacement back (and it costed £60 to ship it to Germany). The good news is that they sent me a replacement unit that looks brand new and sealed. The bad news is that eventually I bought a new one anyway. So the best I can do now is to sell this new item to try to recover some of the losses. Again, I would suggest anyone to get a PSU from a shop where they can bring it back if faulty.

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.
