Questions about this item

What type of motherboard connector does the CSU550AP-3-300 RG6510 RG-PA550I-F require?

The unit is an ATX power supply, so it needs a motherboard with a standard 24-pin ATX main connector and the matching 4-pin or 8-pin CPU power plug.

Will the 550 W RG6510 supply run reliably with an older ATX board that only has a 20-pin main socket?

Yes, the 24-pin plug on this supply splits into 20+4 pins, letting it seat in a legacy 20-pin socket while still delivering the rated 300 W continuous and 550 W peak output.
