    • Rock solid.
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
This is a mega PSU. It does a great job of handling my Astral 5090, even fully loaded. I love the OLED displaying power consumption. It comes with plenty of cables for practically everything.

    • Asus Thor
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
What an absolute powerhouse of a PSU! This thing is the nicest power supply I’ve ever had. It was so easy clicking in the threaded cables that it came with. They made it very easy to manage the cables. I got it when it was on a very nice discount and boy was it worth every penny. This thing comes with a side screen that lets you read the wattage. No issues and well made ... show more

    • Best PSU If You Can Afford It
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
The best PSU I've ever purchased for my gaming PC! I've had Corsair, EVGA, and many different off-brand PSU's. The EVGA was a very close runner up to this one. The ASUS ROG Thor 1200W has extraordinary quality, comes with all cables needed, and the wattage is more than high enough for anything I can throw at it. Pros: - Great build quality - High quality cables - High wattage - Sleek look - Efficient Cons: - Expensive ... show more

    • Great PSU, no so great cables.
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
Come with no issue, new version display the ROG logo every 10 seconds, but I hate the cables so much, they're so basic for such a high end PSU, I HATE Etched cables, next time at least put 16awg in every pin and crimp it properly.

    • Terrible. DO NOT BUY. Major defect. The OLED screen does not work properly. KNOWN BUG ASUS SAID.
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
Terrible. ALL of these have a major defect. The OLED screen works but every 30-60 seconds it malfunctions and displays random lines then goes back to normal. GOOGLE it and you will find MANY people with the same issue. ASUS support said it is a known bug they do not currently have a fix for. It is NOT just one bad unit. Waste of money. Do not buy it. ... show more

    • Handles my 5090 no problem
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
I mean it looks amazing and def helped my pin load on my 5090 as it’s never been this good. Cables are super long and very easy to work with and look amazing. There is an anti burn feature that as it displays the watts, a Asus symbol pops up and then back to wattage. I have read some people think it’s broken but it is as intended. ... show more

    • A solid step-up
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
I recently lost my previous power supply to a power outage. This supply was a significant step-up from the previous supply the fully modular cabling made is fast and easy to install and setup.

    • Great PSU!
Style: Gen III|THOR Size: 1200W|Magnetic OLED Display
Does the job well! Much less random crashes from my GPU taking too much power. Came with more than enough cables for everything I’d need. No difference in volume compared to before coming from a 750w EVGA. It’s definitely on the spendy side but worth it in my opinion. The only downside I’ve found is that when it’s orientation in the fan down position the OLED screen is upside down which makes it look like gibberish until you get used to it 😅 ... show more
