You can work around the 4-pin connector by using an adapter to convert the 8-pin PSU cable to a 4-pin one. Just make sure the adapter is compatible with your motherboard. The APU should still function as long as it receives enough power, but you may need to verify the power requirements and ensure the adapter supports your system’s needs.
I question if it's merely a 4-pin design, but even if that's true, it's sufficient. By official specs, the 4-pin plug supports at least 200 watts—two pairs of wires each handling a minimum of 9A, resulting in roughly 216 watts. The 8-pin connectors are rated for slightly lower current per pair because many wires run close together, allowing about 7A per pair. Thus, the 8-pin version is rated for 4 x 7A x 12V ≈ 336 watts. Choosing the 8-pin is beneficial since more wires reduce current through each pair, minimizing losses in the connections and lowering heat generation. Additionally, extra pairs provide a safety margin; if one fails or gets damaged, you still have redundancy. The 5600G should stay under 80-90 watts of power use, well within the connector and wire limits.
