[SOLVED] Difference CX450 and CX450M

Solution
No. Either version of the CX450 is better than the CX450M in performance.

THE CX450M models are all CWT based. Double forward with DC-DC, a different platform than the CWT based CX450.

Both the CWT and Great Wall CX non modular models are using a more modern LLC Resonant topology also with DC-DC.

Both the CWT and Great Wall models are similar performing and both are better than the modular CX450M in performance.

Solution
I want to know if the CX450M is the same as the CX450, but the CWT version instead of the Great Wall one.

In this guide he refers to the CX450 (Great Wall) and CX450 (CWT) and I want to know if the CX450M is just the CX450 CWT Version. I couldn't find this information anywhere at all.

Need to update with the CX-M 2021, but otherwise it's all there.
 
I had this doubt for a long time and in the end I bought the CX450M (old model). What are the differences ? The CX450 really is a little better but there is a risk beyond your control. The CX450 supplied by CWT is sooooo much quieter than the Great Wall ones. And since I hate noise, I didn't take that risk. Unfortunately, you won't find out who the manufacturer is until you buy it, open the package and look at the PSU sticker.
If it is marked RPS0053 it is provided by CWT and if it is RPS0063 it is provided by Great Wall. Both perform better than the modular one, but you can win the noisier one.
On the other hand, the CX450M is only produced by CWT, so they are incredibly quiet.
I bought one CX450M, 2 months ago and I guarantee that the silence is fantastic.
When in doubt, read this test by Tom Hardware that has a complete analysis of the CX450 - Two Flavors, Tested and Compared (https://www.tomshardware.com/reviews/corsair-cx450-psu,5678.html)
