So... Just out of curiosity, I tried to price one with an R9 290x and the configurator indicated the included 500W PSU was not enough once I chose the R9 290x. I went to change the PSU and found that I couldn't? Don't get me wrong... CyberpowerPC is a great company, but apparently, this Mini-ITX setup is not set up to facilitate the power requirements of AMD's latest cards? It seems like 40A on the 12V as it is with the included PSU would be enough, but the configurator displays the warning symbol?
