    • 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

    • Rugged, over engineered, quality parts, cannot be destroyed
Size: 1300W Style: Dark Power Pro 13
My three thousand dollar gaming PC only draws about 500 watts, why did I buy this monster? Well, it quietly hums under a 40 percent load, it is fully modular and it supports the newer high wattage GPU connection, so instead of two cables and a Y adapter you use one high wattage cable. Clean cable management , quiet, quality over engineered parts and numerous connections for potential future expansion. Even though I am a heavy gamer, this power supply cannot be hurt. You can achieve the same result with something cheaper but I don't want to protect JUST the power supply, I want my other components to last long as well. A monster brick that's barely sipping juice cannot be destroyed. This is a very good purchase. ... show more

    • I miss you EVGA but this will do as a adequate replacement.
Size: 750W Style: Dark Power 13
This be quiet! Dark Power 13 750W power supply is an excellent unit. It's incredibly quiet, performs flawlessly, and the 80 Plus Titanium efficiency is fantastic. The modular design made installation a breeze, and it's future-proof with ATX 3.0 and PCIe 5 support. While I'm very happy with this PSU, I do still miss EVGA's power supply offerings. They set a high bar, and I wish they were still in the game. That being said, this be quiet! unit is a worthy successor and I highly recommend it. ... show more

    • Unreliable
Size: 750W Style: Dark Power 13
I'm a long-time customer of this brand, and I used to swear by their products. But after less then a year this PSU started to give me problems. Under moderate-high load it simply cuts power to the PC. I'm not the only user with this issue, and unfortunately the only recourse would be to ship the package internationally. It's probably just easier to buy a different PSU. I guess I'll save this thing for something less important to me than my enthusiast level build. Best case is I lose some unsaved work. Don't even want to risk damage to my other hardware by continuing to use this product. Worked very well for about six months though! ... show more

Size: 850W Style: Dark Power 13
First one came in faulty, not a so great start, however replacement came easy. Got the new one installed and I'm so glad I got this efficient, modular, and quiet psu all up and running. Definitely better peace of mind than my old Apevia psu. This is one of the go to psu fellas!

    • Extremely quiet
Size: 850W Style: Dark Power 13
I think some of these may have been shipped with bad fans looking at the other reviews as the unit I just received is almost completely silent on power up and idle. The fan does do a quick pulse to 100% on start but it's less than half a second long and only makes a quick 'whooshing air' noise. I haven't noticed any coil whine or other odd noises. Under load it does make some fan noise but it's roughly the same as my machines intake fans (2 Noctua NF-A14 FLX's) so it doesn't really stand out. ... show more
