Solved Help picking a power supply?

Specs: centOS 6.5, 1.6Ghz Atom/2GB
A few weeks back, I purchased a Supermicro dual xeon 1U rackmount server with the intention of transferring its components (mobo, CPUs, RAM) to another chassis (either 4U, or tower).

Its been over a decade since I last played with the innards of a computer and am a bit puzzled by the stated power supply requirements that Supermicro has detailed for this motherboard (Supermicro X7DCA-L):

"To ensure system stability, a 500W (minimum) ATX power supply
[4-pin (+12V), 8-pin (+12V) and 24-pin are required]"

Wattage and ATX form factor I understand, but they lose me on the 4-pin/8-pin, +12V, etc. The last power supply I purchased had a cable with 12-pin adapter on the end that mated perfectly with a 12-pin receptacle on the motherboard.

My original choice was the Seasonic M12II, though that's basically just a guess.

Can anyone tell me if that PS will suffice?

Thanks in advance.

✔ Best Answer
The PSU you picked will suffice. Its more then enough and will work fine. Although I have some more recommendations which I prefer over the one you picked.


Thermaltake SMART Series

Thermaltake TR2 TR-600

I would recommend that you pick one from these three but that's just my opinion. From these four PSU's (the three I recommend and the one you picked) any one will suffice.
