This heating is completely normal. It is caused by a slight amount of "electrical friction" from the current running through the wires. As long as they are not TOO hot, you'll be absolutely fine. On my 1100W X11 rig, even the WALL cables are slightly hot/warm.

This is mostly correct. WARM cables are OK. NOT IDEAL. You want to aim to make your cables COLD/ROOM TEMP. The temp of the cables is directly related to the amount of CURRENT going through them in proportion to the CROSS SECTION OF THE COPPER in the cable.

CHEAP CHINESE cables 99% of the time HAVE SMALLER COPPER WIRE (to keep them cheap) in them than good name bands.

Always remember HOT CABLES COULD = FIRE. (Insulation melts off and causes a short) again though, Good PSU's have Over Current protection and *should* cut off before that.

RE: the warm WALL cable, If you are in a 110v region of the world this is OK. If you are in a 240v region this is not so good.
