Questions about this item

What does the 300 W rating mean for my build?

It is the maximum continuous DC power the unit can deliver across all rails, so the combined draw of CPU, GPU, drives and peripherals should stay below that figure.

How does the ATX form factor limit where I can install it?

The unit follows the standard ATX dimensions and mounting-hole pattern, so it fits any case designed for an ATX power supply.

What clearance do I need for the fan and cable routing?

The cooling fan sits on the bottom or rear depending on orientation; allow enough space behind the case for the fixed cables to bend without sharp kinks.
