PSU power cord

Hi Guys, the power cord to my Enermax revolution 85+ 1050W PSU got damaged so I swapped in the power cord from my Corsair TX850 PSU to run my rig.

Is this ok to do this temporarily while I await my replacement power cord from Enermax?

Any thoughts and comments would be much appreciated as I don't want anything to happen to my system as i just rebuilt it.

Thanks! :D
 
Power cords are basically interchangeable between PSUs. Any power cord should have some kind of current rating on it, but most are at least 10A, and that is plenty for just about any PC.

This is true. Ive got about ten differnt psu power cords that all work with different psus.
 
you got to watch it with the really high end PSUs, some of them use a standard IEC connector which afaict are only rated at 10A as standard (though some manufacturers rate theirs to 15A IIRC) and most cords for those connectors will be only 10A or less. Some do the sensible thing and use the larger (16A standard, some manufacturers rate to 20A) version of the IEC connector.

With IEC cords DO NOT look at the ratings stamped on the connectors, afaict (based on UK experiance, may be different in the USA) those are only ratings of the connectors. You need to look at the type/size of cable and look up it's rating to be sure of it's rating. Over here at least MOST IEC cords use 10A IEC connectors but only 6A flex!

Remember a 1KW PSU with 80% efficiancy at full load running off a poor supply (afaict most PSUs are specced to run down to 80V) could end up drawing drawing close to 16A.
 
Frist off thanks to everybody who has replied.

I've got a lot into my system that I also use for work so I was a little worried about this.

I have got a 980x OCed to 4.6 running a Raid 5 setup with 4 drives, a 2tb storage drive, a SSD and one 5870 cooled by an H70.

At first, I thought my Corsair TX850 psu cord should be fine as a replacment till I get my new one from Enermax. The Corsair plug is rated at 13 amps so I thought that should be enough.

However, an Enermax CSR contacted me later and told me that their engineer told me to be careful doing that because the Revolution 85+ uses a larger power cable than their other ones. I didn't know what they meant by that but I'm assuming they meant current draw.

Anyway, this made me worried that the 13A one I had wouldn't be enough but from everyones comments it seems that might be fine for now.

Unfortunately, Enermax doesn't have any new power cords for that PSU in stock right now so they are trying to figure out another one that will be suitable for the Enermax Revolution 85+ 1050w psu to get to me.

Thanks again.
 
With a PC Power and Cooling 750w and a Tagan ABS itz 700w I got a real thick power cord. I found that the thinner and longer ones I was using were getting real warm in under consistent load (playing Crysis for 3 hours+) so I had to pull my desk out and swap them out and all has been good since. When I upgraded my daughter's computer I got her an Antec Quattro 850 that had the same larger sized power cord, however the Antec Earthwatts 650 in my wife's rig was standard sized. This is kinda telling me that any quality power supply 700w and above needs thicker gauge wire to prevent a fire hazard from being present

The cable you're using now will be fine. Your PSU is 80Plus Silver-certified, meaning at full load it must be 85% efficient or better. That means that even if you were loading the PSU to 100% of its rating, it should still draw no more than about 1235W from the wall. A 13A cable can handle about 1560W of power at 120V, so it is more than capable.
 
I don't see a problem..BUT I have seen people use monitor cables for PSU since they look the same but smaller in size..Trying to diagnose a freezing or shut down problem can be tricky no one thinks to check the cord,i came across it by accident once when the cord was real hot to the PSU and realized it was the wrong cord that the owner said she didn't realize the cords was the same..the PSU cord was on the monitor and the monitor cord was on the PSU..Problem solved.
