On my original PS3 power cable it says 10A 125V, do I have to make sure the cable I use from a computer matches the same?Also can you explain how it works if the cables don't matter
YES, You can use a standard computer power cable for your PS3
Yes, so long as it isn't thin wire like as thin as the A/V Cable almost. But yes, any Monitor/PC Cord will work.
