A LightBurn forum discussion about laser power supplies prompted me to finally organize my pictures.
Without looking at the captions, match each of the following pictures with its description:
- a failed ZYE MYJG60W-Y-1 (came with OMTech laser)
- an unbranded MYJG60W replacement from OMTech
- a Cloudray M60 (bought as a backup)
That was easy, wasn’t it?
As I said in the forum:
My guess is there’s only one ZYE factory (or a dozen clones) producing all the power supplies, then applying whatever sticker the order calls for on the case before dropping it in the carton.
Perhaps Cloudray buys more quality control than the anonymous “brands”, but I wouldn’t lay much money on finding more than two QC bins at the end of the assembly line: either it runs or it doesn’t.

“My guess is there’s only one ZYE factory”
I.e. an electronics contract manufacturer. Who remembers Nokia phones – Nowadays HMD Global Oy?
“The HMD brand is only used for corporate purposes and does not appear in advertising, whereas the name “Nokia Mobile” is used on social media”
