Sub-$75 Mainstream Power Supply Roundup

FSP Saga II 400

The name of the FSP Saga II 400 is a bit grander than the PSU itself, which is of slightly lower quality compared to the other test candidates. At the same time, it's also the most affordable unit in this roundup. This model is one of two devices with no support for 115 V, making it a fancy-looking brick here in the US. You'll only be able to use this one if you're in a country with 230 V power.

At first glance, the 400 W PSU looks like a relic from the past, even if the matte white paint provides a welcome change.

Despite its affordability, FSP's bundle is on par with the other PSUs. The box includes screws, a power cord, and an FSP sticker. Unfortunately, most cables are just under 12 inches long and, aside from the normal ATX, CPU, floppy, and 6-pin PCIe cabling, the Saga II 400 only offers three SATA and Molex connectors. Thus, it might not be suitable for larger enclosures optimized for good air flow. Rather, the Saga II probably belongs in compact systems.

  • 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.

    How come there's no Silverstone strider 400W...

    Im glad to see that the Antec 380D won. I have bought 5 for family and friends have been solid units to date.
  • youssef 2010
    I don't think the Xigmatek PSU can keep the 650W load reliable or else Xigmatek would've rated it to be 650W

    Antec is awesome as always

    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.
