That could be the problem. For 30-40w output, a good power supply should at most be slightly warm and the fan on minimum speed. If your power supply is hotter than the cpu and northbridge heat sink, it is a good sign that it is wasting more power than your motherboard. For your general reference, the D945 atom board with 1 green 3.5" hard drive normally have the following consumption numbers. ~25w range with a pico power supply. ~30w range with a 80 Plus power supply. Numbers could be a 3-4watts higher if you have older hard drives or high performance models. If you are running the server 24/7 non-stop, it makes sense to change to a cheap 80 plus power supply. Look for on sale models and it is not hard to find one for $25-30. In your set-up, it would save 20w or 175kWh per year. This is equal to ~$20 a year or more. You basically get your money back in 2 years and helps the Earth at the same time. -- Honva ------------------------------------------------------------------------ Honva's Profile: http://forums.slimdevices.com/member.php?userid=14948 View this thread: http://forums.slimdevices.com/showthread.php?t=75902 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
