Thought I would share my findings.
Firstly thank you crmaris for the good review based on this I decided to get the NZXT C1200, retiring my Corsair AX1200 (it’s now more than 10 years old). I found that I am using less power now, around 0.5Amps or 115 Watt (@ 230V) less power now, I tested playing the same game for the same period and logging with my Fluke 367FC. I did find that the inrush current is a bit higher at 5.2A, vs the 4.7A my corsair had. But overall super happy.
For my next build, I’m going for a complete white build. Luckily, this psu comes in white, but i saw in a video from Der Bauer that the cables are very loosely connected to the psu. Was this also the case for your unit?

Could you als do a review of the Phanteks revolt 1200?
The difference between the original C1200 and ATX 3.1 version is not just limited to the 12V-2×6 connector. The new version also has one extra PCIe connector, which is good if you have a GPU with three PCIe connectors like the 7900 XTX from AIBs.
Are there any plans to test the be quiet! Straight Power 12 80+ Platinum?
Yes, but I don’t know when I will find the time for it.
