Review: Actually ATX 3.1 - This is an ATX 3.0 also graded for 3.1 and comes with the nice 12v cable for your 4000/5000 series GPUs. Apparently the 3.1 standard is easier for manufacturers to reach over 3.0, so this one is a sound choice indeed. Hybrid mode is quiet AF and i've yet to hear the fan kick in (5800x3d, 4090)
Review: top quality - Amazing PSU, a bit costly but worth the money at least for me. I had Msi and Corsair PSUs, Msi suffered fan rattle and Corsair coil whine both returned. Tried to Chatgpt the problem and ended up ordering this one. Top notch!

### ⭐ Review
*by G***. on 20 April 2025*

The first time I bought a premium power supply from another company and unfortunately I had bad luck. After a thorough checked connection l switching on and PSU blew out the fuse in my main switch. I connected the previous PSU Corsair and fortunately the PC works. Unfortunately, I will not buy a power supply from this company for a long time. I won't take risk again. Thanks fully protection worked. I ordered MSI MEG now.
