There is a formula for working this out as you have dual+12v rails and to be honest it does my head in but my initial reaction looking at the numbers is that it wont run it i will look up the formula and try to get back to you with a def reply so while im doing that i expect you will get about 20 posts telling you exactly
Use this to work it out put your system components in to relevant sections its quite straight forward really.
You will want to have 30amps on the +12 volt rails you have 16+16=32 but it dosent work like that im afraid.
An x1950 pro will probably work with that PSU, for a while anyway. But it will probably cause you all sorts of grief. What you want is an 8600GTS. They are low current draw boards, and almost as powerful as an x1950 pro. Quieter too.
I know this is going back a bit now but I have an LG 32LX2R 32" LCD with a DVI-I connection at the rear.
The HTPC I have recently built has an M2NPV-VM motherboard with onboard DVI output but it is DVI-D, so at present I am unable to use it with the TV as there is no picture when the two are linked using a DVI-D single cable.
I do however have another old PC with a DVI-I graphics card, this works flawlessly with the TV using the same cable.
If I do buy one of these cards and put it in the HTPC, is there any reason it might not work with the TV?
