Power cable specs, help!

[josh.john]

I bought the EVGA spernova 750W PSU. It came with a wall socket cord that is not compatible ( live in Australia ) with where i live. I think it is US standard or something. Regardless though, i found an Australian fitting cable in my house that i had spare. It fits in the back of the PSU and connects to my wall, but i'm a little concered.

 

On the cord my PSU came with it says "10A 125V" and on my spare cord it says "10A 250V". A jump in 125V. Will this hurt my system?

That's just the rating of the cable, so it will be fine.

Any cable that fits will work fine. That voltage is just the max, you can use any voltage under that.

The cables are rated for the 240v but 120v amp range, meaning the cables have the insulation required for the high voltage counties, but the copper for the high ampage counties, it is really Ok and it's normal. What I typed might confuse people who don't do much electrically but it makes sense to those who understand it, don't worry it's fine.

Check the label on the power supply.

 

99.9% sure it will say something like 100v .. 250v AC 50/60 Hz which means it can accept a wide range of input voltages.

 

The connector on the power supply is standardized, and it's one of the two possible which are used all over the world, only the cables with the mains plug change from country to country. You can use any computer/monitor power cable that's available in your country to connet the power supply to the mains socket.

 

Your cable says 125v 10A on it because they have the mains plug for US which works only with those voltages. The thickness of the wires inside, the insulation thickness and so on may not be appropriate for countries which use 230v +/- 10% so that's why it says the cable should only be used with up to 125v mains power.

 

Some cheaper power supplies may say on their label 230v only or something like 200v .. 250v AC only, because power supplies are cheaper to design and manufacture if they are made from the start to work only with the higher AC voltage, so those cheap power supplies simply won't work at 110v AC.

Also if there's a voltage switch on the power supply, make sure it's set appropriately before you plug everything in.

The cable that came with your PSU is designed for a country that uses 115V (Probably North America as you said), you are from Australia, you use 240V. The PSU can support 100V to 240V IIRC (If it isn't that, it is somewhere around that), so just use the Australian cable and you will be fine.
