Power is there but I didn't like how the module outlet sits directly on top of the power switch instead of being on the opposite side of the power switch. Check and see if your pc case has any interference with cables before buying this PSU.

Great PSU and I like the way they handled the 12HVPWR cabling, I think it might prove to be much better than the standard 12+4 to 12+4 for the gpu.
The only downside for me was that I had thought the shift would help in cable management, but it didn't as much as I had hoped. That being said the connectors are easier to reach if need be in the future!

Doea not work with 5090. Stay away if you have a 5090 else your pc will shutdown. Get an ATX 3.1 not ATX 3.0

I have this paried with an 17 13700k and a 4090 and no issues the 12VHPWR cable is a very nice addition to this as i didnt want to use the stock cable that came with the 4090 so far so good highly recommend getting this PSU the side paneling is a bonus
