I am working on building my own NAS (because honestly, even Synology's NAS's didn't look overly appealing)
I believe I cannot use an ATX psu for a Micro ATX motherboard, but many Micro ATX psu's are not highly 80+ certified. I would like to go from something that was exceptionally well graded by jonnyguru if at all possible.

Wattage range: 450-600 (600 would be overkill, but if it is more efficient than the 450 minimum, then I would go for it)

I know there's the whole 'just because it's efficient doesn't mean you need a four digit watt power supply for something less than 1/4th of it's recommended load' thing, which is why 600 is the absolute max (like I said it would be total overkill)

Also, forgive me if I improperly labeled this under "components", but isn't a psu considered a component?

anyway, again, thank you in advance and thank you those who tolerate my nonsense ^_^

You can use an ATX PSU just fine on a MicroATX motherboard. For a NAS you don't need a high wattage PSU, a 300w unit would be fine (though hard to find)

I'm a little confused by exactly what you're asking - there's nothing sold as a microatx power supply. Most consumer PSUs are ATX with SFX ones for very small cases (there are a few other more obscure form factors). Most microatx motherboards will be in microatx cases with ATX power supplies. So I don't have much idea of what form factor you're actually asking about.

And secondly, I'm not comfortable giving specific PSU recommendations without any knowledge of the hardware involved (though with a NAS, we're talking about heavy loads). Of course we're not going to recommend 1200W PSUs on a rig that will max out at 200W - if you're assuming we don't know what we're talking about, why ask us for advice?

Thank you Snipergod87 for the clarification and you solved my issue.

Thank you DSzymborski for your help as well because it helped me clarify my question and following statements in the help request:

Several people I have consulted in pms on other sites and desktop chat clients like to have ridiculous overhead (minimum of 30% overspec of what their system needs) So I was adding that little part in to deter those types of people away. In no way did I mean to disrespect or "put down" practical people such as yourself. For me, a 15-25% overhead is more than sufficient (depending on the overall efficiency rating and wattage capacity of the psu itself).

I asked the question I did because I know there are motherboards out there from nano ITX up to SSI EEB and even pcpartpicker's list of psu types are a bit mind-blowing.

so thank you both for your help and assistance on this project, and if i could, i would choose both of your inputs as the solution.

But we haven't actually helped you pick out a PSU yet!

Recommended overhead in a lot of builds depends on the usage. In gaming builds with more variance in the GPU usage and/or the possibility of an overclock, I like a bit more room.

Headroom for a NAS is going to be based in a large part on how many hard drives you may end up with. I very frequently end up recommending the SeaSonic G 360 to people, but whether that is appropriate or not for your particular build, would definitely need more info.

This is the link to the NAS I am thinking about building:
https://pcpartpicker.com/user/Krayven/saved/RMj23C

1: I know the processor is a tad overkill, but I want to make sure it can handle a lot of stuff because this will be a nas/very limited entertainment center by itself.

2: I intend to use FREENAS and its software RAID10 configuration and use the SSD's as cache drives to get the more important most highly used stuff in and out quickly while using hte 4tb drives as storage.
the nvme is the boot drive where the OS will work from.

It's because I saw that particular review is why I chose that psu: Jonnyguru gave it a Rock Solid 10 in all areas. (I have read at least 20 other reviews from Jonnyguru involving power supplies. Not just the intro / score+summary. I read the whole review and see why he gave it those scores.)

Thank you very much Snipergod87 for your help in fully solving this. Your solution (combined with the solid explanation of the guy who told me ATX/MicroATX means nothing to a power supply) has finally put this thread to rest ^_^.
