The 12V rail started at 11.91V and dropped to 11.76V in Test 6. This gives us worst-case regulation of 0.24V (2%) and a drop of 0.15V (1.25%). The 5V rail had maximum and minimum values of 5.17V and 5.12V respectively, giving us 0.17V (3.4%) regulation and a 0.05V (1%) variation. Finally, the 3.3V rail started at 3.36V and dropped to 3.34V, giving us 0.06V (1.81%) regulation and 0.02V (0.61%) variation. This is a perfectly acceptable result, but there is a little room for improvement. The fact that the 12V rail was always a bit under, while the 5V rail was a bit over shows that this power supply really was originally designed to be loaded more heavily on the 5V rail. To be honest, we are getting really sick and tired of seeing 5V heavy power supplies on the market these days. From here on in, it will mean a point off the score.

The efficiency throughout the tests was what we would consider to be poor, as it never made it to 80%. It started off just under 74%, peaked at a hair over 79% in Test 4, and was just under 76% under full load. The exhaust temperature was 5°C warmer than the intake in test 1, and 17°C warmer in Test 6, which is a little high for this power level, but not too surprising given the efficiency results. One area where this unit really differed from the other two HP-D3057F3H power supplies I have run load tests on was with the overload test. Both of the units I previously tested held up just fine to a 450W overload, and shut down gracefully when asked for more. This unit blew up under the same conditions. I didn’t catch it on camera, but it wasn’t overly spectacular – just a pop with a bit of a flash.

The ripple levels were very low at all times – well below a quarter of the maximum allowed at all times. This is better result than last time – partly because the unit I used last time was a bit older and had a bit more usage behind it than this one, and partly because the DS1M12 Stingray oscilloscope is less sensitive to stray spikes and interference than the Hantek oscilloscope used last time.
