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.
@Onomatopoeia @Damage Hm, that’s interesting for data centers, but I’m not sure a 30TB ssd is representative of what home users would have. Power consumption of 2 x 4TB nvme compared to an 8TB hdd would be more informative.
A quick search gave me this table, which claims that the higher the PCIe support (eg more lanes), the more power an nvme consumes. So sticking with a slower 4TB nvme (which is still comparatively fast!) would be best for minimizing power consumption compared to an hdd.
