Is anything on the PSU higher than the large capacitor ? The large cap is 30mm high which is exactly the same height as the original PSU. The transformers wires look like may be sticking up slightly wrong, but that shouldn't give you the height difference you seem to have. All wires on top of the transformer are supposed to be routed downwards around the outside of the transformer rather than above it. But even so, you seem to have lost more height than that somehow..

I'm wondering if there is a difference with the mounting bracket. I don't suppose you have a second ST to verify that it's identical?

I've got the same PSU in a Mega ST, STE and an H5 and they always fit. The only time I had trouble was when the motherboard wasn't lined up with the positioning pins on the base or when the PSU mounting bracket was incorrectly fitted.

Could you please post photos of the PSU mounting bracket, so we can see if it's been bent or is somehow different in some way.

Since you've adjusted the PSU position can you please post a picture of the IEC socket and power switch so we can check the alignment as the should be central in their openings.

Also can you please post images of the PSU from every side so we can have a look at the assembly, thanks.

Seeing the thread title... what an interesting coincidence. Just yesterday I noticed the same thing for the Exxos Falcon PSU. I had a Falcon which I was unable to close due to a different issue, that was fixed and imagine my surprise when I found out that the PSU itself is another obstacle in the way.

Thanks to help from a talented friend, we could lower the bracket's legs so it fits again but I was rather disappointed to see this. :-(

(esp. because I'm quite fond of this PSU, it helped me where the others had failed!)
