  • Really good, quiet 1000 Watt power supply
Size: 1000W Style: Dark Power 13
This power supply has all the modern capabilities that a modern, ATX 3.0 Power Supply should have. It is energy-saving and very quiet. Pros * Includes all Cables * Settable to Single rail or 4 rail for 12 Volt outputs * Very Quiet * Titanium Efficiency * 12VHPWR connector cable ATX 3.0 for newest GPUs * 10-year manufacturer’s warranty * 1000 Watts will easily power just about anything, including a AMD 7950X CPU, and a NVidia 4090 GPU of my rig * modular cables at Power Supply end don't use as many pins, meaning they are not as crowded on the back side of the power supply * No RGB lights (if you don't like lighting) Cons * modular cables at Power Supply end are not standard, meaning a failed cable is harder to replace * Supply has an inrush (starting) current of 51 Amps (using 120 Volt), and that might make some overly sensitive 15 Amp circuit breakers trip unexpectedly when turning on the computer, but is unlikely * 12VHPWR connector cable ATX 3.0 for newest GPUs is hard to bend enough to clear case for at least some Nvidia 4090 GPUs * No USB data connector to get data about temperature, voltage outputs and to control and sense power supply's fan speed * No RGB lights (If you like lighting) ... show more

  • Rock Solid PSU That Will Not Let You Down.
Size: 1000W Style: Dark Power 13
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. ... show more

  • Overkill? Maybe. Reliable? Absolutely.
Size: 1000W Style: Dark Power 13
I bought this to replace a gold-rated unit that was struggling with power spikes, and the be quiet! Dark Power 13 hasn't broken a sweat. The 80 Plus Titanium efficiency is top-tier, and you can tell be quiet! didn't cut any corners on the internal components. It’s a heavy, well-built piece of kit. The fan doesn't even spin up most of the time when I’m just browsing or working, which keeps the whole room quieter. If you have the budget for a 1000W unit, the 10-year warranty makes this a very safe long-term investment for your PC. ... show more

  • Blown PSU, terrible customer service.
Size: 1000W Style: Dark Power 13
Been building computers for about 15 years now. First PSU to ever blow on me. I'm fortunate I caught it before I left my home, as it started to smell like an electrical fire in my house. I've been trying to RMA a replacement. I've left probably five voicemails and sent multiple emails. When they finally got back to me, I sent pictures and receipts immediately and I still haven't gotten an answer about getting a replacement. I've also had power state failures ever since I built my computer a year ago, and after doing some research, this line is tied to that exact issue. At this point, seeing the issues with this product line, I think it's safer to go with something like Corsair, Super Flower or Seasonic. It's not just that the PSU failed, but that their customer service is now non existent. They were great a year ago, but something has changed. Look somewhere else. The product is low quality. ... show more

  • Fantastic
Size: 1000W Style: Dark Power 13
Prime day made this inexpensive and well worth the money. Fits right into my case and is super quiet. No issues with it even after a year even after I've taken it out and put back in to test with other rigs so it's good and durable. With its modular design, cable management is a breeze since you only use the cables you need. ... show more

  • Almost perfect
Size: 1000W Style: Dark Power 13
Arrived in perfect condition. Installed very easily and modular cables connect seamlessly. Only problem is the 12VHPWR cable is too stiff at the plug on my 4090 so cannot be curved downward to clear the side of the case. And I have a very large Lian Li 011 Dynamic Evo XL so the 12VHPWR will probably not work in any case with a conventional horizontal mount. Only a vertical or upright mount of the video card will work. Any horizontal mount will require an aftermarket 12VHPWR cable (good luck finding one of those) or 90 degree adapter. But the power supply itself is great. ... show more
