Power cord variations

I'm rescuing a machine (PC). But, the AC power inlet differs from a "standard" modular inlet. I.e., a "standard modular power cord" won't fit.



I'm pretty sure it is a 110VAC device -- or autoranging 110/220.



But, the "blades" of the *inlet* (not "plug" as I don't have the power cord to examine) are oriented like the blades on my 220V servers. I.e., instead of:



| | |



They are oriented as:


- - -



Is this a voltage distinction? Or, current (ampacity)? (I'm sure a "standard", flimsy "modular power cord" doesn't have the current carrying capacity for the power supply's rating -- so, this may be a way to ensure the "right" power cord is used instead of "a conveniently available" one)



[I'll have to read the label on the power supply more carefully before taking possession of it]

** Sounds like an IEC C21 or C22 plug.

These have a 20A rating.

My guess(tm) is the latter.

Like one of these? Kinda looks like the 3rd or 4th from the left, which which are both

208/220/230 VAC.

Try a NEMA 6-15R Panel Mount:

Sorry, I have no idea. I haven't seen that on any PC power supply yet.

Google for the maker and model number of the PC power supply. There might also be a label on the power supply case with the basic specs.

In the US, that is a 220 V plug, often used for air conditioners.

It's not a *plug* but, rather, an inlet. Just like the inlet on the rear of your PC to which the modular power cord is connected that, ultimately, terminates in a PLUG that mates with the RECEPTACLE in your wall/power strip.

These inlets differ from the one on your PC because your PC probably draws < 7A from the (120VAC) mains. This PC draws 10A @ 110V (or 5A @ 220V -- autoranging).

So, I can either use a modular cord that terminates in a 110V "plug"

*or* a 220V plug but, in the case of the former, the typical flimsy power cords that come with most kit won't be capable of safely handling the current -- and, thus, won't mechanically fit the inlet.
