- Reviewed in the United States on September 27, 2024Style: Prime|2 in 1 ColorSize: 750WVerified PurchaseI think Asus uses rebranded Seasonics, but in either case, it’s always good to spend the money for a good quality PSU and this one has been working great powering up my 4070 Super. The GPU isn’t super power hungry so the 750w has been working without any issues.
Simple to install with the modular cables and it’s pretty quiet when idle. It’s a very slight fan noise when it’s completely quiet. Personally I use open-back headphones and I can’t hear it at all.
It’s reversible setup to show white or black is a nice concept in theory but with certain setups and customization you can’t get it to show the side of the color you want. I would rather have it all white. But that’s my only nitpick.

Others state it is a capacitor issue or fan issue ... Hopefully it's nothing serious... This is a beast of a unit for my setup I9 99k and 4070ti super by ASUS
- Reviewed in the United States on February 6, 2024Style: TUF GamingSize: 850WVerified PurchaseI 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).
- Reviewed in the United States on September 22, 2024Style: TUF GamingSize: 750WVerified PurchaseMy PC would restart every time I launched any game that pushes the graphics card. Otherwise the PC was functioning perfectly. After updating all software & drivers, reinstalling the game and trying everything else I could thing of, I could not run the game for 5 minutes before the PC would restart. I ordered this replacement power supply and installed it and the PC now works perfectly when running any program or game. I deducted one point from the score because the instructions that came with the PS are extremely Spartan (they basically say plug in the connectors and turn on the computer in 200 different languages). The PS is heavy duty and seems to be quality made.

5.0 out of 5 stars Excellent Performance and Stunning Design
Style: TUF GamingSize: 1000W|WhiteVerified PurchaseI recently upgraded my PC with the ASUS TUF Gaming 1000W Gold White Edition power supply, and I couldn't be more impressed! The build quality is exceptional, with a sleek white finish that perfectly complements my setup. The 80+ Gold certification ensures top-notch efficiency, and the 1000W power output is more than enough for my high-performance gaming rig.
Installation was a breeze thanks to its fully modular design, which helped with cable management. The fan is quiet even under load, and the PSU runs incredibly cool, which is a huge bonus for system stability. The TUF Gaming series has always been known for its durability, and this PSU lives up to that reputation, delivering reliable and consistent power.
Whether you're building a high-end gaming PC or a powerful workstation, the ASUS TUF Gaming 1000W Gold White Edition is an excellent choice. Highly recommended!
