    • Quiet, Powerful, and Built Like a Tank
Style: ROG Strix|Platinum Size: 1200W
I upgraded to the ASUS ROG Strix 1200W Platinum power supply, and it has honestly been one of the most solid components in my entire build. From the moment I opened the box, it felt high-quality. The cables are fully modular and easy to route, the finish looks premium, and installation was straightforward. Once it was powered on, the first thing I noticed was how quiet it is. Even when my system is under load with a high-end GPU and a lot of accessories, the PSU barely makes a sound. Performance has been flawless. The voltage stays stable, there’s no coil whine, and the system feels extremely smooth even during long gaming sessions or heavy multitasking. The ATX 3.1 support gives me peace of mind for next-gen GPUs, and the GPU-first voltage stabilizer is actually noticeable because my graphics card no longer has those tiny dips or flickers that I used to get with cheaper power supplies. It just runs clean and consistent. This is the kind of PSU that you install once and don’t worry about again. It runs cool, it’s efficient, and the 10-year warranty says a lot about how confident ASUS is with the build quality. If you’re putting together a high-end system and want something reliable and quiet with plenty of power overhead, this is easily one of the best options out right now. ... show more

    • Absolute Beast of a Power Supply – Perfect for High-End GPUs
Style: ROG Strix|Platinum Size: 1200W
The absolute beast of power supplies. I bought this specifically so my PC could properly support my newly purchased RTX 5090 graphics card, and it delivers exactly what I needed. Everything about this PSU is top-notch—build quality, stability, and performance. Especially impressive is the included 5090 power cable. It feels solid and secure, and it’s reassuring to use the manufacturer-supplied cable designed for high-power GPUs. Yes, it’s expensive—but with hardware like a 5090, this is not the place to cut corners. A reliable power supply protects your entire system, and this one gives real peace of mind. Total recommendation if you can afford it. If you’re investing in a high-end GPU, spending a couple hundred more on a quality PSU that can protect it just makes sense. Verdict: BUY. ... show more

    • Top PSU with all the extras.
Style: ROG Strix|Platinum Size: 1200W
Review Image by LordChumley
What a monster power supply. Works without issue or fail and provided more than enough stable power for 285k/Asus 5090 running full AI loads or 4k gaming. Love that is monitors(through gpu tweak 3) all the individual power pins on the gpu. No worries about an expensive 5090 burning up. I also use TG Wireview as well for extra insurance. The supplied cables are flexible enough to fit anywhere and are of high quality. Easy to install and manage the wires. ... show more

    • Amazing PSU w RTX Power Connection

Amazing PSU especially with the new power connector for RTX 5090 GPUs. My previous ASUS Thor 2 was good, but it would start beeping under heavy load. I was afraid it would shutdown on its own like my old EVGA 1000W. So I decided to upgrade to the new ASUS ROG Strix 1200W. No beeps, no problems, and the fan is even more silent. Easy integration with my PC setup (AMD 9900X, RTX 5090, MSI Carbon WIFI X870E, 64GB RAM, ASUS TUF Case). ... show more

    • Great PSU, but the cables are kinda lacking in my opinion.
Style: ROG Strix|Platinum Size: 1200W
Very nice PSU with a great feature set, & extremely quiet... My only complaint, & the sole reason I knocked off a star was purely because of the cables, & lack of cable combs on the 24-pin mobo connector... Not only are they clear against blackish-grey thin-sleeved diamond patterned leatherette cables (personally, I think they should be black rather than clear), but they're only on the 12VHPWR which for a PSU at this price & of this quality, you should have thicker cables with more combs included in the set... Although I will say, I am glad there's a discount coupon code for Cablemod in the box, as I made use of it to order new 24-pin, & PSU cables with combs. ... show more
