Good quality, no complaints
Been using this for a few years now with my AMD Ryzen 7700 based system. Started with a Radeon RX 5700 XT and now have a RX 9060 XT that it powers without problems. Being modular allowed me to leave out power connectors I didn't need and cleaned up the space inside the case nicely. Fan is quiet as well.

Winner Winner WOW,
You know when you pick up something and it instantly feels like a quality product? This has that feel - everything from the packaging to the product. It comes with every cable you could need out of the box - even one with a MOLEX connector for older systems. I love its modular approach too where you only plug in the cables you need, it keeps my case free of unnecessary cables and that allows the air inside to flow freely - and it just plain looks better. I was impressed to see that it had two PCIE cables - one targeted to a dressy system where you see inside - the other was a all-out performance cable that has embedded capacitors to reduce voltage ripple on high powered GPUs! Very cool. I absolutely love the screen that displays the wattage currently being used and now that I have it I cant imagine ever going back without one, every PSU should have that! - Im glad I bought the 850w version too, Im not using anywhere near the power I thought I was. Useful accessories are included too, 'ROG Branded' Velcro cable straps and even cable combs so that when you peek inside your case each cable is perfectly and neatly separated ...if your into that kind of thing. I thought I would use the "silent' switch on the back of the PSU but honestly the fan is so quiet that I couldn't tell the difference between it running and not - so I just left it on. Overall Awesome GPU - I absolutely love it, they killed it with this PSU.

Best looking PSU out there!
1200W may be an overkill (especially for RTX 3080/3090), but I felt the need to "future proof" my PSU for future parts. Was browsing and came across this beat looking PSU which fits perfectly on my custom ASUS PC And overall i'm very happy with it. The PSU........ -Feels very premium (Box is well secured) -comes with custom sleeve cables -Come with connectors and zip pins so you can organised your cables -Cool looking sticker (if that even matters to you hahaha) -Helpful OLED panel that shows how much wattage's you are using. Been seeing many people concerned on how many watts they are using or need for the RTX 3000 cards yet I can simply look at my PC to see my numbers haha. -Awesome design and love the RGB. Unfortunately I can't customize the colors directly for some odd reason yet since I have other ASUS parts that are compatible with custom RGB (MB, CPU cooler, etc) I was able to change the PSU RGB colors when I changed my motherboards RGB colors. So I guess that's how it works. Kinda interesting that with a 3950x and 2080s (no overclocking), on 1440p ultrawide max settings gaming, I was using around 300 watts in total. Kinda gave me 2nd thoughts if this was an overkill but at the same time, it's nice to future proof your PSU and not being able to worry about upgrading in the future especially when it comes to PSU shortages. Overall great PSU, may be a bit expensive, but I feel this PSU is meant for custom PC builds.

This thang is HEAVY. That good kinda heavy ;)
To start off. The pictures do not do this beastly thing justice. The shell ROG chose to use is really aesthetically pleasing and feels thicker and more solid than 99% of the power supplies I’ve touched (veteran pc repair shop tech) and the cables that they included that were braided bend really well, and look good when combed with the combs they come with. I use this in my main test bench pc for like gpu testing cpu testing motherboard testing because having the wattage readout has came in WAY handier than you would think as a repairman. I can tell if parts aren’t working correctly just based on there power draw. Sounds crazy but when you’ve seen what I’ve seen it’s one less thing I have to worry about having on hand when it’s literally built into my bench. But I was building and testing with a 7950x and a 4090, and me and the boss were skeptical, but this psu powered both, it probably could do this for a while but I do not recommend this for that. My modest 5700x with a 6950xt will happily sit right dead at 50% load on this thing when gaming heavy titles. Which is where this thing GLEAMS. 92.6 percent efficient, just a note, that’s almost in titanium efficiency territory. Damn fine work ROG. Had one at the shop so I bought a second for my rig lol. Do not buy if the price isn’t sub 150 i say as seasonic offers some for cheaper than that. And this is just a heavily modded seasonic power supply.

Well built.
Excellent product. It is well built and comes with extra ties for cable management. I've had this for almost 3 years now without a single issue. Quality: Asus, at least in my experience, has always made good quality items across multiple categories. This power supply is in a computer with all other Asus TUF series components. This is being used with a TUF 3070 and there are no issues.

Great Platinum PSU
PSU worked well and great. The cables were of high quality and felt like I was getting a premium package. Has lasted me 3-4 years and it is still going strong.

Quiet, Clean, and Dependable Power Supply
PROs: PSUs are probably the most hidden yet one of the most important parts in a build. It's quiet even without using the 0DB feature, modular so cable management is easy and if your case supports it has a nice OLED screen to show watts, something that most PSUs don't have but can be super useful for trouble shooting. While I can't see mine since it all depends on the case, being able to open my side panel and quickly check my watts without using any third party software is pretty nice. Con: The only "issue" I've had is purely based on my case, I had to mount it upside down so it had better ventilation and so I could see the screen at all. The fix of course if planning a build is just get a case with PSU visible and with room for ventilation from the top.

Powerful and a Beaut
Love this PSU, went for a bit more power than I needed because the price was fantastic. Love the OLED display, fits perfectly in my case that shows it off.
