    • ROG-THOR-1200P2: Mo Powaaa!
Style: THOR II|ATX Size: 1200W
Pros: Plenty of usable wattage for a gaming build. Currently powering an AMD 9800 X3D and FE 5090. Easy-to-read display showing current power draw Customizable RGB Nice and bright RGB with full spectrum color range REALLY QUIET even at full load. The GPU fans are louder than this PSU Cons -Not really a hit on the PSU, but syncing Armory Crate RGB isn't a bit of a chore. But once you get it right, it looks great -Depending on your case, you've got to be smart about cable management. Comes with a plethora of power cables, but they are long and will require some savvy tucking. I'm sure it's for full-size cases, and I use a test bench, so I had to invest in a lot of cable ties to keep it neat. You won't be disappointed. Lot's of headroom for upgrades. ... show more

    • GREAT PS - size is awesome, plenty of power
Style: LOKI|SFX Size: 1200W
Review Image by vesposit vesposit
2nd one I have purchased - first was the 1000watt for other ITX mobo build, this was the 1200 watt for new compact ATX build in Mechanic Master C34 Pro case... worked like a charm... super quiet... plenty of power and size is great since I wanted to build a compact system. These are awesome. PC is in case below just behind the LONG Graphic card, would not fit a standard ATX PS... but this SFX was a dream fit and extra room when done. ... show more

    • High price, but quality...
Style: LOKI|SFX Size: 850W
Lovely small form factor piwer supply that brings the juice for a moderate and medium tier build. 850Watts is a good plateau before you start to kick higher prices for more power draw. It's quiet, keeps cool, and works well to add a small extra rgb color on the back side of my pc, while i don't see it during the day, i do notice the glow at night. ... show more

    • Great product!
Style: THOR II|ATX Size: 1000W
Tested PSU as soon as it arrived. Tested good, mounted it in the case. Waiting on the rest of the parts. LEDs are good for new "Display PC" case. Modular cables eliminate cord clutter.

    • Worth it. Best power supply I have had!
Style: THOR II|ATX Size: 1000W
OK let’s face it. You don’t know me. But I am a huge ASUS fan and I have been buying their products for years. However, I have only purchased motherboards, video cards, monitors, but I’ve never purchased a power supply of their brand. I did my research and I ended up getting this one because I needed 1000 W and I was looking for something add long-term and something that has had good reviews and most of all that had a really good rating. And this one delivered all that. Now I’ve been running this for a month now and I can tell you it’s very powerful and it runs cool and very quiet. All the bells and whistles are not a plus for me but it may be for you like the lights on the side and it’s cool mirror look, but mine will be hidden and not viable for the naked eye. So I needed something to add a good rating and a good warranty. My last power supply lasted nine years so, I chose this and I am so glad I did. If you look at all the specs, everything matches up and then some. They have had years of pros and cons to all their products in their brand, but I’m here to tell you this one delivers. But like anything, do your research, pay attention to what you need in your environment, but I honestly feel this would be a good fit for just about anybody that needs this much power. ... show more

    • Best SFX psu on the market
Style: LOKI|SFX Size: 850W
By far best psu I have owned. Noise level is unnoticeable When in use. Bought used to save money and when it arrived it looked new like it had never been used before. Highly recommend for SFX-L PC build.

Style: LOKI|SFX Size: 1200W
This thing is a beast. Looks great and has plenty of power. It is more then my machine needed. The fan only kicks on when needed. RGB looks great through the side of my case. the small form factor would fit any size case. highly recommended

I owned the Thor 1 1000w PSU. The cables were wrapped in fabric. The Thor 3 is like a plastic type rubber. I think they should have stayed with the fabric wrapped cables. It's not enough to knock off a star though. I'll be getting a cablemod kit. Really like this PSU. It's made by Seasonic. I chose the 1200w version because of that. Wentai makes the 1600w version which had a high failure rate. Supposedly the fan on 0db would not spin when the power supply got overheated causing it to pop. ... show more
