Antec Minuet replacement PSU?

That's Antec's proprietary size.

Antec MT-352 Power Supply Dimensions:

2.7” (H) x 3.6” (W) x 6.1” (D) / 69 mm (H) x 92 mm (W) x 155 mm (D)


The only form factor that comes close is TFX which has the following physical dimensions in its specs:

2.76” (H) x 3.35” (W) x 6.89” (D) / 70 mm (H) x 85 mm (W) x 175 mm (D)

Seasonic 350W TFX PSUs representing the best of the TFX form factor PSUs:
Dimensions: 2.5"(H) x 3.3"(W) x 6.9"(D) / 63.5 mm (H) x 85 mm (W) x 175 mm (D)

Thanks for the input - the screw holes on the seasonic do not look like they will line up correctly. I have a PSU at the moment that looks similar and I can figure out how to connect that one at all. Unless I drill new ones? Is that even advisable?  

Consult Page 30 in the following document for the standardized TFX mounting hole spacing specs:

http://www.formfactors.org/developer/specs/TFX12V%202.0...

The measurements are all specified in mm.

You should be able to determine just how close your current mounting bracket holes are to this TFX standard.

I have 28 of these power supplies that are functional removed from my work that is closing an office location. If you need any contact me at zh3j5-3501356491@sale.craigslist.org
