PSU power cable help.

vertica · 25 Oct 2010 at 23:46

I've taken delivery of two power supplies today (not new and not actually for me) both have a connection that i've not seen before on the rear panel.
All the power supplies i've ever seen have used a 'kettle plug', and from a quick look on US and EU sites it would appear they do to.

these two units have a larger, rectangular connection with the three pins horizontal, rather than being a squashed hexagon with vertical pins.

Anyone know if i can get a UK power lead to fit them?

If it makes any difference they are coolermaster 1250W PSUs as is the pic

so are these new boxed units? didnt come with a suitable cable?

I would be asking for correct EU model versions of these PSU's

i think contacting coolermaster is your best bet

They are not new or boxed - they were shipped with some workstations. I think the issue is the hardware goes all over the world so i'm assuming they are the standard in the far east or something? no use to me!

If no-one can suggest anything, (my google-ing skills dont seem up to it) then i'll get on to the sender in the morning.

It's an IEC C19 connector. Rated for 16A instead of 13A for higher end applications such as UPS systems and high end workstations. You should be able a standard cable for it.

Looks like a C19 type...

EDIT: Much cheaper...

Cheers chaps. Problem solved! have yourselves an e-cookie.

Looking at it, it must stem from the US (and others) having 110V mains.
Given ours is nominally 230V RMS AC, and rated to a max of 13A. this gives ~3kW of power, which is more than double that of the power supplies intake (even taking the efficiencies into account.)
On a 110V supply 13A only delivers 1.4kW which the power supply could feasible draw at max load, hence the need for the higher rated cable.

Maybe - it's an IEC standard lead, and IEC are an international body, but the USA tends to do its own thing when it comes to standards. But let's blame America anyway

Tealc · 26 Oct 2010 at 09:56

Yep it's America's fault because of their lower voltage. The 10A kettle lead will only do about 1100W in the US. The 16A one brings it up to about 1760W. I think it'll be a while before a 10A connector is unsufficient in Europe.

So they build one PSU with this connector so it can work everywhere, that makes it cheaper to produce.

You would expect that the PSUs would come with the required lead though, especially given that the IEC C19 isn't as widespread as the IEC C13.

We used to make these things in work and one customer used to have the 16A one for US markets and the 10A one for Euro markets, they were coffee machine makers.

Coolermaster will have the right adapter, so call them - but they will probably charge you.
