FSP Saga II 400: Measurements

Efficiency meets 80 PLUS specifications:

Efficiency under different load profiles:

Obviously, we couldn't test whether the FSP Saga II 400 meets all 80 PLUS criteria, due to its lack of 115 V support. The 230 V efficiency test results of 83, 85, and 81 percent under 20, 50, and 100 percents loads, respectively, are quite good, though. The efficiency of the FSP PSU decreases as the load gets lighter, but not as much as the competing models from Corsair and Xigmatek. The rest of the measurements are fine, but not good enough to beat any of the other PSUs in this test.

  • 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.
