Questions about this item

What wattage does the 320 W TFX unit actually deliver on the 20+4 pin motherboard connector?

The supply is rated for 320 W total output; the 20+4 pin connector carries the combined load for motherboard, CPU and peripherals up to that limit.

Will this TFX power supply fit the mounting holes and depth of an HP Bestec TFX0220D5WA chassis?

It is built to the TFX form factor and is listed as a direct replacement for the HP Bestec TFX0220D5WA 504966-001 unit.

Do I need to flip a voltage selector before plugging the 100/240 V TFX PSU into mains?

No selector is present; the unit auto-ranges across 100 V to 240 V, so you simply connect the IEC cable and power on.
