Only in one review: Current 38.3 A (DPS-460EB A); In test 470 W (DPS-460EB A); Ripple 600 mV (DPS-460EB A).

DPS-460EB A: This compact, well-built used PSU handled 470 W, but has high ripple and a loud fan.

500 W Switching Power Supply for Audio Amplifiers: The power supply is well made and efficient, but overheats; it can deliver only 250–300 W continuously.
