Hi. I just purchased a Lenovo Thinkcentre M91p (machine type 0266) which has an external 150w power supply. I purchased it to be used as a HTPC and i want to put a gpu and more ram in it. The problem is the power supply, all the ones i see people talk about have an internal 240w power supply. On the back of the pc is a DC in jack thats directly into the motherboard itself.
I ran some calculations on power usage and the site i used said the recommended power supply size for the standard unit is 150w with a peak load of 123w. Adding the gpu alone pushes the peak load to 140w (nvidia gt730) with a recommended supply of 180w.
My question basically is how can i upgrade an external power supply when all i can find is standard 150w external replacements or internal ones that wont be of any use

Yeah I found out after I purchased it that there is 3 different models of m91p. The external 150w power supply isn't sufficient enough for any video card. I spoke to the seller not long ago and he told me I can switch over the PC to a hp8200 sff so that fixes all my issues as its a micro atx board with an internal 240w
Thanks for the help
