Review conclusion	Recommended	With reservations

Only in one review: In test 720 W (DPX6012S); Efficiency 98.9 % (RK8009); Weight 258 g (DPX6012S); Price 40.62 $ (DPX6012S).

RK8009: The converter showed low ripple, high efficiency and good thermal performance; its main drawback is limited input-voltage headroom.

DPX6012S: The board is powerful and fairly well designed, but accuracy is middling, functionality is limited, and the software is rough.
