Works on an NZXT H7 Flow case perfectly
Great PSU. I generally get SeaSonic Focus GX PSUs and decided to try this out. Very happy with the purchase, hope it lasts like the SeaSonics.

Amazing PSU
The wires are super clean and plenty of length. Its a very quiet PSU and I highly recommend. I've seen a few reviews of people saying there is not enough PCIE cable slots but that's not true. There are three slots labeled CPU/PCIE the 2 on the left are CPU and the slot below the 12V Adapter is the spot for the extra PCIE cable that is included for GPUs with 24 Pin Connectors like the 7900XTX.

More power in short stature
Fits perfectly in the Corsir 7000x tower case. The short length alleviates the pinching you get from similar 850 w PSUs. Corsair included more than enough cables so I didn't have go and purchase any more white braided cables. And the white on white case completes that custom look.

Corsair RMX level performance and quality at much lower price...
I usually use the X series power supplies from Corsair but decided to give their e version a try. Glad I chose this one over the x version, just could rationalize the price difference especially at the special price I picked it up for...

A must for any white pc build
This came with all the cables needed for my 5080, 7800x3d build. Love the white cables they give you, It came with a cable that could connect directly to my white 5080 gpu to complete the build!
