I have an older 747 that I want to upgrade the psu's in. This sat in its original box in a basement for like 8 years so they might be fine, but I'd rather buy newer ones. It has a PWS-1K41P-1R. The current new version is PWS-1K23A-SQ and even used, very expensive. Anyone know if there are other versions that are compatible?

The old manual says this is a 23-pin connector (https://store.supermicro.com/us_en/...a-2r/PWS-1K41P-1R/PWS-1K41P-1R_quick_spec.pdf), but the newer version, according to their shop, which looks like the same pins, says 19-pin. The PDB is PDB-PT747-4648.

Yes, it will fit. The PDB-PT747-4648 has 27-pair connectors, that means any PSU with the matching form factor up to 27 pairs will fit (19,23,27 pairs will all fit).
