ZOTAC Geforce 970 GTX .... you will need a minimum of a 500w psu to support that...bigger is better.
The HP H8-1234 machines that I see have a 300w psu.
I have installed a new ZOTAC Geforce 970 GTX into an HP H8-1234 running windows 7, with AMD 970 chip and 10 GB of DDR3. When I turn the machine on, all that is displayed is a screen which says "Press ESC to enter the start menu" and will not respond to any key stroke. When I put the old ZOTAC Geforce 630 card back in the machine it boots correctly with display and function. Is this a bad video board?
