Minimum Power Cable Rating for Corsair VS650W PSU ?

[ari1717]

Hi Guys,

I'm putting together my first PC and as luck would have it, I got a Corsair VS650 650W PSU that came with a UK plug (rectangularish prongs as opposed to the roundish ones we use in India). The seller says all his PSUs have the same problem. He offered me a replacement power cable which claims to support up to 10A (ampere).

The sticker attached to the original Corsair power cable clearly says 13A power plug needed (if the original has to be removed for any reason). Now I thought I'd look around and find a power cable that matches 13A (and say no to the seller's solution). Unfortunately I can't find a power cable rated above 10A.

Will it be safe to run my PC on a 10A cable ? My rig will be -

AMD FX 8320/Intel i5 4460
Nvidia GTX 960
Corsair Vengeance 8GB RAM
standard HDD and Optical Drive

An alternative seems to be a power adapter that transforms the UK plug into an Indian plug. But I've heard they are often not dependable when used over extended periods of time.

I don't want to end up buying another PSU! Any help would be deeply appreciated!

If you are using a 240 volt power source, the cable and its fuse(if it has one) is good for 2400 watts. So yeah it is more than upto the task.

Thanks nukemaster! The voltage rating in India is 220V so I believe it should not be very different from 240V ? The cable he's offering has no fuse, it looks just like the cable extending from my laptop's charger's brick to the power point (except that it is supposed to work with the PSU).

If there's no fuse in the cable, should I take any precautions to compensate for it ?

Thanks again!

With 220 volts(and 10 amps) it would be 2200 watts as a rating(may more than enough).

I am not sure about built in fuses in India to be honest. Here in Canada(and USA) we do not have Fuses in plugs, just in the circuit panel.

As long as the cable is the right fit , the power supply should work.

From what Corsair lists it looks like that power supply is good for 200-240 volts so you are good to go for that part.

Thanks again for clearing up my doubts. I doubt even a top end Vishera (rated at 220W TDP) would eat up 2200W of power at any point of time so I guess even an overclocked 8320 (not that I intend to overclock it) should have enough juice at all times.

I'm thinking of getting a spike buster since the panel I will use with the PC is rather old and I'm not sure what state any fuses (no idea really, I'm a history student 😀) are in.

So it seems everything boils down to the right fit 😀 I guess that shouldn't be difficult (or I'll have the seller's head!).

Lastly, uhmmm....can I connect JUST the PSU and power cable and perhaps hope to see some fan inside whirring ? So I know I'm working with a good component before I move forward with the build ?

Thanks again!

By the timillee you pull 2200 watts from the wall, you would have long kd off the power supply.
It was just the math. 220 watts x 10 amps = 2200 watts(That is more power than my 3 computers in this room). I have piles of power cables for my area(Canada/USA[we use the same plugs]). I will NEVER need to find more.

Moving on. Power supplies can be forces to turn on without a board connected, but some have a minimum load they want to see(this may lead to it shutting right back off). To start a power supply without hardware connected, you have to use a paperclip or similar to pull the PS_ON(green wire) wire down to ground(black wire). This is a just used as a jumper to connect the green PS_ON lead to one of the many grounds on the power supply.
