I'm putting together a build for my Lenovo X220t as follows: GTS450 1GB DDR3 - Despite what it says here and to my surprise this card does not have any supplementary 6-pin connections. BPLUS TECH - PE4L-EC060A v2.1b 120W CE approved AC Adapter Power Supply I've got a few questions: Hardware - Do I simply plug the DC plug into the DC socket on the PE4L? I saw some older threads that talked about jumpers and having to use extra USB power but these seem rather outdated. - The socket in the PE4L has no information, is it a 5.5mmx2.5mm like the power supply I am buying? Software - The laptop is currently running windows 8, as far as I can tell there are now NVIDIA Optimus drivers for Win 8, but will this be a problem? To sum up, this is my understanding of what I need to do once everything has arrived. Install latest NVIDIA drivers. Plug GTS450 into PE4L. Plug DC PSU into DC socket on PE4L. (Hopefully it fits) Plug DC PSU into wall socket. Plug expresscard into laptop slot. Let me know if I've gotten anything horribly wrong. Thanks!
