Only in one review: Power 800 W (NVVV S-800-70); Ripple 500 mV (NVVV S-800-70); Protection 11.5 A (NVVV S-800-70); Temperature rise 230 °C (NVVV S-800-70).

RD6030-Max: The unit delivered about 1831 W with roughly 88% system efficiency; the author liked its large display and power.

NVVV S-800-70: A decent, stable power supply, but it needs modification because of overheating resistors and a noisy fan.
