Hi everyone,
for 20 years now i run servers in my own home to host my stuff. Because i am living in europe with quite high price tags for electricity i am always searching for ways to make my servers more power efficient.

But finding a power efficient ATX PSU with performes well in ranges around 20-25W, where my server idles most of the time, is quite challenging.

Dont get me wrong, the Server has an very efficient PSU, a Super-Flower SF450P14XE Golden Green Pro but thats now 14 years old (but serves me well). I bought it for 55€ back in the days.
Over the years i tried various budget insider tips regarding efficent PSU’s (for example the Cooler Master MWE400) which all were also good but not better than the 14 year old Super Flower, which i think is kind of sad.

Just yesterday i tried a 160W PicoPSU combined with a 150W DELL DA-1 powerbrick (which should also be quite efficient), but it was the same. My Server used 1-3W more than with the Super-Flower.

Long story short: are there any efficient PSU out there that you can recommend for loads around 20-25W, that dont have a price tag like a kidney on the blackmarket?

I also have seen people trying to mod old Dell Server PSU with are 750W with platinum rating an are cheap on ebay, but thats another story.

    Good to know! Wow, I’m impressed by the low power draw.

    Thanks, I wanted to add a video card for conversion jobs, but didn’t think it had enough power.

      The 300W XE3 PSU should offer plenty of overhead for a quality low-profile GPU and an i7-7700k (though you can’t overclock it). Mine also runs a Precision 3420 CPU cooler and has an additional intake fan up front.
