The answer Lenovo support gave is not true. The motherboard and PSU have a proprietary 10-pin ATX connector, and there is no adapter currently sold that will allow you to use 98% of the psus out there that use the 20/24 pin connections. I found this out the hard way, after I had bought the machine, new psu, and new graphics card and was about to install them. What this means is that the psu is effectively non-upgradeable unless you get a new motherboard as well - and therefore neither is the graphics card (although I was able to run a Nvidia GTX 750ti SC, which uses the PCI-E to draw power and has a low TDP). Do NOT buy this machine if you intend to upgrade the PSU and graphics card. Other than this very significant handicap it's a nice machine.
Sorry, there was a problem. Please try again later.There is an adapter which will allow you to use a standard PSU. Since Best Buy doesn't allow URL links here, all I can say is the adapter is available at modDIY dot com for around fifteen dollars.
