Questions about this item

Will the 280 watt rating cover a fully loaded OptiPlex GX745 or 755?

The 280 watt unit matches the original specification for both the OptiPlex GX745 and 755, so it supports the same component configurations those systems were designed for.

What power connector standard does the JK930 use for the OptiPlex motherboard?

It uses the proprietary Dell connector keyed for the OptiPlex GX745 and 755 motherboards, so it plugs in directly without adapters.
