This method is usually fine for lower wattage CPUs. Be aware that using
this method provides only one additional +12V lead (wire) and one ground
from the PSU. The 4 pin aux CPU power standard provides two +12V leads
and two grounds. The new 8 pin aux standard provides 4 +12V leads and 4
grounds.
If running an 80+ watt CPU I recommend against this converter strategy
as you'll have only 1/2 of the aux +12V conductors needed to safely
carry the current load. You may sneak by at 80W, but at 95W you're
tickling the dragon, and with a 135W CPU you will fry some wires,
ruining your PSU, and likely the mobo as well. Decent PSUs with the
proper aux connectors are really inexpensive. Why gamble?
