Questions about this item

How much heat and noise does the 300W unit with its single fan produce during all-day use?

The 300W design uses one fan to move air through the chassis; typical office workloads keep the fan at low speed so noise stays modest and case temperatures remain manageable.

Which cables must already be present in the case for the 20+4-pin ATX, 4-pin ATX12V and three SATA connectors to plug in?

Your motherboard needs a 20+4-pin ATX socket and a 4-pin ATX12V socket, while each drive requires a SATA power port; the supply also includes two peripheral and one floppy connector for older devices.

Will the grey 300W ATX unit power a legacy Compaq system that originally used the DPS-300GB A 463317-001?

Yes, this Replace Power model is built to match the DPS-300GB A 463317-001 pin-out and 300W rating, so it fits the same ATX mounting holes and connector layout.
