My primary PC is a Q9650 on a ASUS MAXIMUS II with 8GB of Cosair DDR2
800 RAM with two ASUS EAH4870 video cards. I am running three hard
drives, a WD Velociraptor, a Seagate 500GB and a Maxtor 300GB all
SATA II, plus a DVD burner, CD Burner and floppy I have couple of
USB self powered hubs with a scanner plugged into one of them. Power
supply is PCP&C 750 watt silencer. I dual boot XP64 and Vista 64.
Vista 64 is my primary OS. I use three monitors, a 30 inch on one EAH
4870 and two 24 inch on the other EAH4870. If I want to play game I
boot into XP64 because I have Crossfire running which does not
support multimonitor and screws up my setup every time I switch to it
in Vista 64. In Vista 64 I am doing 2D and my video cards are barely
doing anything. I rarely play a game.
This setup has been running since December. This morning I turned
on my monitors and discovered the PC shut down on it's own over
night. I booted up and discovered that I had lost my two 24 inch
monitors. I then booted into XP32 and discovered the same thing. Then
I pulled off the cover and could see two all the fans working and two
red lights illuminated on the card that wasn't working. I called ASUS
who tells me it is a power issue. That my 750 watts is not enough for
my setup, they say I need 800 ... which I disagree with. Besides
this PCP&C probably is capable of putting out more then 750. But in
my setup I can not possible be using this much power doing what I am doing.
In any case I am thinking of testing by hooking up a second PS just
to the bad video card and seeing if that changes anything.... anybody
see anything wrong with doing that?
thanks
