Here's a small graphic at xbit labs showing the actual power consumption on the various voltage lines, of an ati x1950 pro reference board, while being used. http://www.xbitlabs.com/misc/picture...r_full.gif&1=1

Peak load while in 3D mode is showing 65.7 watts, note that +12 volt reading of 34.7 watts being drawn from the agp slot, that's about 2.8 Amps, and +12 volt EXT. 25.4 watts being drawn from the direct power supply connection is about 2.11 Amps. Total of about 4.9 Amps from the 12 volt rail. About 1.6 amps from the +3.3 volt rail.

Add these values to the total PEAK draw of each voltage line for all of the motherboard and all the other parts in your system, including the NEW CPU, and the chassis fans, then check the power supply's available power for each of those voltage lines to see if you are within the specs of the power supply.

Your deskstar hard drive power consumption specs show a peak load of 1.72Amps on the +12V line and .68Amps on the +5V line. This translates to 20 Watts on the +12V line, and 3.4Watts on the +5V line.

Typical lite on optical drive power draw: 1.5 amps on +12V line, 1.5Amps on +5V line. This translates to 18Watts on the +12V line and 7.5Watts on the 5 volt line.


Max power draw from a compatible ADO5200IAA5DD amd x2 64 5200 processor is 47.7Amps at 1.3 to 1.35Volts, this translates to an average of 63.2 Watts.


For reference, the HD3850 AGP card has a suggestion to have atleast a 450Watt PSU, or greater, with atleast 30Amps on the +12 volt line, and the card requires (two) 4 pin molex connectors directly from the PSU, these are the same connectors that plug into the hard drives [edit] I found the graphic for the HD 3850 but it doesn't mention if it's AGP or PCI-E, power consumption should be close between the two; Peak watts at 63.1, Drawing around 32.4 from the card interface, total of around 2.7Amps, and 28 watts from the +12V line directly from the power supply, total of around 2.4Amps, and 1.76Watts from the 3.3V olt line, for a total of around .53Amps..

Here's an interesting post related to issues regarding your motherboard with the use of a phenom processor, and incompatible vga card http://209.85.173.104/search?q=cache...lnk&cd=6&gl=us

Refrences made to the agp cards not functioning properly in 8x mode, hardware failure etc.. This goes a little ways to backing up the importance of following their compatability list. Also some insite into how things might turn out worse even if the compatability list is followed, mostly regarding using the phenom based CPU though.
