ATX and CPU cables too rigid.
Good PSU but the cables bundled could be better. The ATX and CPU cables are so rigid and have large unbendable sections where insulation overlaps, that I can not use them in my micro case (Silverstone PS15). Had to order another cable set with flexible cables.

Still not sure
I bought this to conserve powr and support my NVIDIA card in my DELL T1700. This PSU model is a ZERO fan noise buy design until it calls for fan to run. I've maxxed the computer 3 times doing video edit and CAD 3d rendering for several hours and the PSU fan never started. 2 case fans, CPU fan and video card fan all ran full speed to during those exercises. There's no way to override the PSU configuration to test the fan. PSU is working I guess but as a passive power supply.

Bought New Came Used
I bought this psu new and when it was delivered it came in a poly bag. The psu box had visible damage and had no plastic seal. I could feel and hear the psu sliding around in the box, and when I opened it up the psu had no foam protecting it, there were scuff marks all over the thing. Also, the cables were terribly wrapped with that black wire twisty thing.

Perfect
Bought this for an office computer build. It's excellent quality, great noise level (i.e., quiet), and easy to work with. It powers an i5 11400, no gpu.

Works Perfectly
A deal I couldn’t let pass. Exactly what I needed & is working as expected.

Just a great PSU. My i5-10700 is idling at 17watts with a discrete graphics card! T600 quadro. 2 x NVME. 2 X 10 TB hdd (spun down).

Exceeds my expectations

Got a faulty unit, all the pins were completely dead, no voltage. Got a full refund but still 2/5 because it was a major hassle and extremely inconvenient and time consuming to completely disassemble the computer I was building, troubleshoot all the parts, send back the faulty unit and get a replacement.
