Questions about this item

Which motherboard power connectors must my board provide for this Replace Power AP-MPS3ATX30-33 unit?

The supply includes one 20+4-pin ATX connector and one 4-pin ATX12V connector; your motherboard needs matching sockets for both.

Can I keep my existing IDE hard drives and floppy drive when installing this 300W replacement?

Yes — the unit provides two peripheral power connectors for IDE drives and one floppy drive connector for legacy 3.5-inch drives.

How do I confirm the AP-MPS3ATX30-33 is delivering power correctly after fitting it?

With the 20+4-pin and 4-pin cables seated, the single fan should spin and the system should POST; the three SATA power connectors will then supply attached drives.
