Antec EA-380D Green: Measurements

Efficiency in accordance with the 80 PLUS specification:

Efficiency under different load profiles:

Antec's PSU shows very well here. The 380 W PSU even manages to take a slight lead in our efficiency measurements. The two best PSUs from the previous bunch, the Huntkey Jumper 450B and the Xigmatek NRP PC402, can only just match the Antec EA-380D Green. The EA-380D performs well in the other measurements, as well.

Only the nine degree increase in temperature under load sticks out, which it is most likely attributable to the small fan.

  • That was scary seeing the AXP PSU blow up...

    I still remember buying my Corsair VX550W for $91CAD just a year and half ago. Amazing how prices have come down for cheap, capable and yet quality PSUs over time.

    Oh, and it was interesting to see a real PSU blow up :D

  • Patrick u sure the antec blows the hot air into the case?
    Looking at the picture and the fan alignment it seems otherwise.

    I wish the Xigmatek was available here. All we have are expensive 750w and 850w versions.

    Im glad to see that the Antec 380D won. I have bought 5 for family and friends have been solid units to date.

    I don't think the Xigmatek PSU can keep the 650W load reliable or else Xigmatek would've rated it to be 650W

    Is there no way to measure how stable the power on each rail is? Some PSU's Ive seen are very efficient but their rails drops below recommended power delivery meaning components are starved. Some even fluxuate which can damage components over time. The only other thing I feel is missing is capacitor aging. Is there any way to simulate 2-3 years use? Most PSU's I use in my main machine get handed down to another rig or sold. 2nd hand PSU's could be false economy!

    great video, Ive always wanted to see a PSU explode lol.
