A TUF high quality PSU!!
Since installing the ASUS TUF Gaming 1000W PSU, I can confidently say it delivers on quality and performance. This unit is currently powering my Ryzen 7 9800X3D, RTX 5070 Ti, 64GB of DDR5 RAM, two NVMe SSDs, and an AIO liquid cooler, and it has been absolutely flawless. Right out of the box, everything feels premium. The packaging is excellent, it includes TUF branded Velcro cable management straps, and even a certificate of testing, which is a really nice touch and inspires confidence. The PSU itself feels very solid and well built. The sleeved cables are fantastic. They look great, are very flexible, and are extremely easy to work with. Cable management was smooth, and the GPU power cable bends cleanly without feeling stiff or putting stress on the connector, which made installation much easier. In terms of performance, the system runs quiet and stable, with no electrical noise or issues, even under load. Having the extra wattage provides plenty of headroom and peace of mind for light CPU tuning and future upgrades. Overall, this feels like a high quality, long term investment. If you are looking for a reliable and well built PSU that can comfortably handle a high end system, I highly recommend this one.

Reliable, Quiet, and Plenty of Headroom
I’m using the ASUS TUF Gaming 850W Gold PSU in my gaming PC, paired with an AMD Ryzen 7 7800X3D and my 9070XT 16GB graphics card, and it has been rock-solid. No issues with stability, power delivery, or noise since installation. The fully modular design made cable management easy, and the unit feels very well built. It runs quietly under load and provides more than enough headroom for gaming and general use. Having ATX 3.0 compatibility is also reassuring for modern components and future upgrades. Overall, it does exactly what you want from a power supply: stable, quiet, and dependable. If you’re building a high-end gaming PC and want something you don’t have to think about once it’s installed, this has been a great choice.

Beautiful PSU and well built, but one flaw...
I went with ASUS TUF brand for my PC since I wanted it to be as TUF as possible (heh). I almost went another brand, but decided to try this. I went 850 watt so I didn't have to use too much % of PSU power like I would with a 750 watt. I was very pleased with the build quality. It doesn't have the fancy velcro (whoever uses those really?) pouch for the modular cables like other brands do, just a thick clear plastic bag. This is the most expensive PSU I have ever bought. The wires are unlike any PSU I've installed in my life, all the cables are not glued together into one strip like other brands. It's both a good and bad thing. Good thing is I can choose exactly where the tension is going to be on the cables, the bad thing is that they can get very unruly like a stack of Christmas lights if you aren't careful. BUT that doesn't mean I like it less. This fan also needs to be installed upside-down if you want the fan taking cool air in from the bottom and blowing out the back. If you point the fan up it will suck air from inside the PC and blow it out the back instead. I chose option one (upside-down) because I don't want the PSU eating hot air from the case. I’m not someone who places my PC case on a carpeting and is stuck with option 2. The “bad” thing about this PSU is that the fan is very loud and makes a loud "humming" noise (look up '250 HZ sine wave' video, it's about that tone) when it heats up even a teeny bit. There is no low db mode, but it is usually quiet. I'm used to the sound already, but it caught me off guard- easily the loudest PSU I ever bought. Setting my two front intake case fans to DC mode so they turn off at 35°C seemed to quiet down the PSU A LOT though. I did the same thing for my GPU fans. Did wonders for the noise! Temps are still in the low 30s even with only the CPU and back fan on. I might even turn off my ARBG to see if it gets even quieter (I doubt it though since LEDs take practically nothing to power). The humming is not ideal though. It can sound like a bad case of tinnitus after a while. During gaming (which is usually what I do), it’s not even noticable. Do I regret my buy? Nope. Will I get a different brand next time? Only if the ASUS TUF one fails on me in under 10 years (my old PC's PSU is still going after 12 years).

Really good :)
The size of the power supply is pretty good not really much to say on that, The colors of the cables obviously are going to be blocked out so they could be pretty good if you want to make a all black PC and the quality of the cables are pretty good too feeling pretty reliable and durable and the installation is pretty easy and understandable to do and of course due to it being a modular power supply you don't need to have every single cable plugged in. So I would say this is a pretty good power supply especially a 1000 w unit even if my PC does not consume anywhere near 500w but it's still good to have a lot of headroom for future upgrading.

Perfect for my needs
Worked great for my needs, no massive complaints here. It's powering an RX 7900XTX and a 7800X3D. native 3.1 support, so no adapter needed for 12VHPWR. Pretty basic cables, I may get custom cables in the future. The slotted fan grill bends easily, so be careful.

Good Power Supply! For 1000W easy to connect everything only thing I noticed is you can hear the fans if your playing or even downloading something, but for the value it’s good!
