Questions about this item

What does the 420W rating mean once the unit is installed in an HP Pavilion a1312n?

It supplies up to 420W of total power to the motherboard, drives and peripherals in that chassis, matching the original specification for the listed Pavilion models.

What ATX connector standard is used and what does it support in practice?

A 20+4 pin ATX connector is provided, allowing it to plug into both 20-pin and 24-pin motherboard sockets found in the compatible HP systems.

What physical space and mounting does the grey ATX unit need inside the case?

It fits a standard ATX cut-out, uses an 80mm fan for cooling and weighs 0.1, so it mounts with four screws like the original supply in the Pavilion a1314n, a1319h, a1320n, a1283w and a1330e CTO.
