I'm sure the product 'be quiet! Dark Power Pro 12 1200W, BN646' is great and will work awesomely.
Would of been 5 stars if it had not come in its own box vs an Amazon Box to not show the world what is at my front door.
I've bought other things that were about the same size and they came in an Amazon Box.
Just saying that for something that costs $399.99+tax should come in an Amazon Box to hide the electronic gear so it doesn't get stolen.

Update:
I now have it hooked up to 5 AMD gpu's for btc mining(4 570's & 1 580).
I'm now saving about 150 watts by just using this PSU.
What a huge difference from a 1000w 80+ Gold psu from Apevia.
There's still 4 8 pin connectors left over to use too.
I'm using 1 rail( 2 8 pins) to power 1 570 and the 5 risers. The 4 other gpu's are on 2 rails(2 8 pins each).
I'm using on average of 711 watts for the 5 gpu's, 5 risers, 19 gpu mb that has an i3-7100 cpu along with 16GB of DDR4 3200 speed ram and 6 140mm fans to help blow air past the 5 gpu's.
What a beast of a power supply.
I'll def be buying more of this type of PSU's from Be Quite.
Highly recommended, despite the bad reviews.
I had zero issues hooking this up and powering my pc.

It looks cool but...

Reviewed in the United States on July 28, 2022

This power supply looks cool with its brushed finish and runs quite as expected. However I think this unit misses the mark for power supplies. First of the unit does half a nice finish to the main frame of the unit but all the edges are unfinished leaving a sharp edge on every corner the same goes for the plastic on every connector. Expect to put more force then the usual when trying to connect everything up even on the power supply itself, you won't even get the satisfying click when the connection is made knowing its secure. The cable management that comes with the kit is simple and effective. If your using a large case like a 7000D from corsair then cable extensions might be required.

Blew up my UPS, tripped my circuit breaker

Reviewed in the United States on August 10, 2021

Verified Purchase

I haven't looked into RMA'ing this yet, and I can't tell how much of an outlier this experience was. To understand my setup: My rig is only about 2 months old and included this Dark Power 2 1500, an ASUS TUF 3090, a Ryzen 5900x, and various components of similar quality. I'm a huge Be Quiet! believer, as their fans are literally the best in the market, so my case is from the same company and so are most of its fans. My PC was plugged into a Cyberpower 1500w UPS and the UPS was plugged into the wall. Only one 1440p monitor and my PC were plugged into the UPS. If PCPartpicker is to be believed, the power usage of my components should never have topped around 800w. I knew such a large PSU was a bit "extra", but with the PSU shortage and pricing at the time, I was getting a great deal, and before this instance, I'd only had the best experience with Be Quiet products and it worked well, powering my machine. But....

Fast forward 2 months, I pressed the power button on my PC and instantly heard a pop come from my Cyberpower UPS and the error tone whining. I looked over to see that smoke was coming out of the top of the UPS and it was flashing Error. The PC never fully turned on, its lights only flashed for a moment, but I made sure to flip the switch directly on the PSU to Off and I unplugged the UPS from the wall. The UPS was only a little warm to touch, and aside from the smoke coming out of it, seemed normal. However, I needed to run a few more tests.

I started with just a small charger and it worked fine in that outlet, so I held my breath and, with the PSU still switched Off, I plugged my PC directly into that outlet. The plug only got maybe 25% of the way into the socket when I heard the electricity pop and the lights in that room instantly went out. Mind you: The PSU was switched Off when this happened. Downstairs, the circuit breaker was tripped and I just needed to flip it back. It took a couple days, but I replaced the Be Quiet PSU with another one (luckily, the rest of the PC seems totally undamaged), this time only 1000w from, in my eyes, a lesser brand, and scheduled time with an electrician.

The electrician took a look at the circuit box and said that it looked professionally put together and he wasn't seeing anything wrong with it. The fuse was fine and the amount of power draw coming into the house was totally normal. We ran my PC (now, with the fresh 1000w PSU) plugged into the same outlet and everything else in that room, which includes two other PCs and an AC window unit. Even with the AC running at full blast, we never went past 8 amps, which I was told is far within safe parameters for that circuit. I asked him what he thought happened, and he said that he's not familiar with PC components but to him, the PSU sounded like the culprit.

Anyway, that was a really long story that I clearly just needed to get off my chest with a bunch of, I'm assuming, PC enthusiasts who, like me, have too much disposable income right now. The PC I'm referring to is actually housed in a Be Quiet 802 case and has their unbelievably silent Pure Wings fans running inside of it to keep it cool, so I clearly love their products. In this case, though, I think their PSU let me down and I'm very lucky that the rest of my components, especially the ultra-rare 3090, seem totally fine. I plan to call customer service in the coming days.

This PSU reduced my GPU's coil whine to the point of being nearly inaudible

Reviewed in the United States on October 29, 2021

Verified Purchase

I just installed this PSU yesterday, and it is amazing. The build quality is excellent and the fan was inaudible when I tested the PSU outside of my PC's case. This PSU has also reduced my 3080 ti's coil whine to being nearly inaudible - I can only hear my GPU's coil whine if I put my head next to my PC case now, whereas before, I could hear it across the entire room (I came from a Corsair PSU). The only negative I thing I have to say about this are about the cables - they look nice and are individually sleeved, but they're extremely rigid and hard to work with. I ended up breaking the sleeving on one of the PCIE cables while plugging it into my GPU. The cable combs are also not great and hard to put on the cables. They don't move once at all once you have them on, so prepare beforehand as to where you want the combs to be. I might look at getting custom combs just to make the cables look nicer. In addition, this PSU really should have come with at least a few single 8-pin PCIE cables instead of all of the 2x 6+2 pin PCIE cables. That would have made cable management much easier.

Overall rating would be a 4.5/5 due to my issues with the cables, but Amazon doesn't allow a 4.5/5.

Replaced my Seasonic SS-1050XP that I've had since 2014 which was causing shut downs on high gaming loads. That is no longer a problem with the be quiet! Dark Power Pro 12 1200W. I also instantly noticed a difference in noise as well as this PSU is dead silent even at full load whereas my Seasonic's fan was very loud when it turned on. This PSU oozes premium and the look and texture are top of the line, imo better than the corsair AX line. Powers my oc'd Ryzen 5800X and EVGA 3090 FTW3 without a hitch.

I do have one complaint - the cables are really long. Like, reeeeeaaallly long. This is great if you have a large case, but I installed this in a 011 dynamic and the cables are a mess on the PSU side. It took some effort to tuck the cables so that I could close the side panel. My Seasonic cables were much easier to manage. I also don't like the 2X2+6pin PCIE per cables. This is a high-end PSU that's most likely going to be used with high-end GPUs which should only be powered with 1 PCIE pin per cable. It would make the cable mess much easier to manage.

All in all - highly recommend if you have a high-end PC that demands the best and most cleanest power delivery.

Una verdadera joya

Hola a todos!

Hoy la he recibido, salvo el mal rato con el operador de la ultima milla que daño parcialmente la caja. Me entretuve un buen rato ordenando los cables y poniendo sus separadores para darle un poco mas de orden visual, los cables son lo suficiente largos para conectar los 2 auxiliares de la mobo. No he conectado el bracket de OCK, por ahora no lo haré. Mi antigua fuente era una ANTEC HPC 100W Platinum y simplemente la cambie por tema de antiguedad.
Pues es muy silenciosa, no es tan pesada al ser la versión digital, pensé lo sería mas. Por ahora es todo y a disfrutarla :)

Beast of a case. Read psu size limitations. needs improved airflow

Reviewed in the United States on June 15, 2021

Verified Purchase

I bought this case to build a new setup for the house. I wanted a quiet case that had plenty of room to add equipment. The build of the case is good. I would be VERY careful of the front case door as the hinges are plastic and break easily. I am disappointed with the company in general as I bought their brand power supply (Dark Power 1200) and it is too large for the suggested mounting locations. Cable Management is good. They provide velcro and zip tied for the ample amount of tie down locations.
I cannot comment on the LED lights as I am not using them.
Not for first time builders.

The sexiest PSU that you will ever need.

Reviewed in the United States on January 25, 2021

This this is premium and well worth the money spend. My only regret was not getting the 1500 watt version as pc component are drawing more and more wattage theses days. Seriously, my modest pc now requires 1000 wattage (which led me to buy this awesome beast of a PSU) just because i was very blessed to be able to upgrade my GPU, the powercolor rx 6900 xt and that beast of a GPU needs about 1000 total PC wattage to run properly. I am blessed and happy now.

Died within minutes

Reviewed in the United States on February 20, 2021

Verified Purchase

On a new build with partial hardware installed AMD 3970x, asrock trx40, and gtx 1070 (just a placeholder while testing the system), no additional drives.. so all in all wayyyy under the rated power for this thing. It POSTs and was idle in the bios for about 5 minutes, then it blew. Loud pop, electrical sizzling, could see light coming out of the mesh so sparks/flame internally, and a bunch of smoke.

Removing it and replacing with an old 750w to test the other components verifies that everything else is working as expected and it wasn't anywhere near being overloaded.

2 stars because it was easy to install, the cables are very nice to work with and when it died it didn't take any other components with it. So good job whoever designed that part of the system, or maybe I got lucky, either way.. don't really recommend it.

Its a nice box I guess?

Reviewed in the United States on May 2, 2021

The packaging was nice and that's about it. I was hopping this psu would solve the issue I have w/ my current 850w psu crashing when trying to stream and play games on my 3090. Install was a pain in the ass. At first I thought the individually wrapped cables was awesome but it became a cable management nightmare. The cables are really stiff compared to my cable mod extensions I have on my other psu. After finally getting the psu installed I plugged it in w/ the switch set to off and it started to power the pc. This was my first red flag since now that there was no other way to stop power going to the psu other than unplugging it. Went to boot my pc and it would crash as soon as windows would load the login page. It crashed 3 times and each time i took it apart and made sure all cables were seated correctly. 3 times I rewired my pc and each time it crashed on start up. Put in my 850w XPG and now my pc works completely fine. This was a very horrible 1st experience w/ be quiet and now I'll be avoiding other products they make.
