The 20-pin socket has only 1 yellow 12V wire, and it's good for only 8
amps or so, mostly because of the contacts, and motherboards with CPUs
faster than about 2.0 GHz will draw slightly more current than that
from the 12V output. But if the contacts haven't become charred or the
surrounding nylon body hasn't darkened much, you should be OK.
Prolonged operation without the 4-pin 12V connector can melt the nylon
or char the contacts, and motherboard voltage regulators without
undervoltage protection can overcompensate for the low incoming voltage
and damage themselves.<!-- ~MESSAGE_AFTER~ -->
