thanks, I have found a psu and a cable. [URL]  [URL] 
  So I want to upgrade my desktop with a gpu, but i need a better psu as currently, I have the 260watt psu with no pcie power. Although I need help to figure out if I need to buy an adapter, because I know certain things like the motherboard is proprietary, and I want to remove the cpu vent for a exhaust fan. (NOTE: I also want to know if the power cable for the fan will plug in anywhere on the board. SPECS: I5-11400 [NAME].6GHZ, 12 gb ram (1 4gb dimm, 1 8gb dimm [NAME]), PNY XLR8 GTX 750 TI), 260 watt Dell psu, DVD-ROM optical drive. If anybody has matter on this then feel free to reply.
