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? -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
