Are you seeing this voltage on a scope or on a multi-meter? Meters probably don't respond fast enough to give an accurate value. The voltage may go lower than the value you see. > > The PSU is a Ahanix MPT-350D and has an AMD sticker on it.

They get pretty warm so I guess they draw an Amp or two each. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
