Questions about this item

Does this 300 W ATX unit fit my HP ProDesk 550 G2 chassis?

Yes — it matches the D11-300N1A pin-out and part numbers 759045-001 and 759763-001 used in the 550 G2, 405 G2 and 400 G2 models.

Can I keep my existing HP ProDesk 400 G2 motherboard with this supply?

The connector layout and 300 W rating are identical to the original 759045-001 unit, so the 400 G2 board will power up without changes.
