Questions about this item

Will the 140 x 86 x 150 mm PS2/ATX form factor fit my CSE-731D-300B chassis?

Yes, this PWS-305-PQ unit is validated for the CSE-731D-300B and CSE-731i-300B chassis, matching the 140 x 86 x 150 mm dimensions and PS2/ATX form factor.

How do I connect the 24-pin ATX and 4-pin 12V cables to a Supermicro SYS-5038D-I motherboard?

Plug the single 24-pin ATX connector into the motherboard main power socket and the 4-pin 12V cable into the CPU power header; both cables are fixed to the unit.
