What to do if PSU doesn't have pci-e cable for connection to graphics card ?

[Guest]

My PSU is 450W, i have opened the case and saw that the wires coming from PSU are connected to HD,dvd r/w and few are connected to motherboard directly,

How to check whether my PSU has PCI-E cable or not for connecting to graphics card ?
Please anyone help ?

PCI-E cables look like this: https://www.google.co.uk/search?q=pci-e+cable&tbm=isch&imgil=hntvsEI1dU7fsM%253A%253BRlAvccc4fxbQDM%253Bhttp%25253A%25252F%25252Fwww.techpowerup.com%25252Fforums%25252Fthreads%25252Fquestion-on-my-psu-and-pci-6-2-pin-connector.202937%25252F&source=iu&pf=m&fir=hntvsEI1dU7fsM%253A%252CRlAvccc4fxbQDM%252C_&biw=1600&bih=788&dpr=1.2&usg=__oD-_CYD22FkwLpDaJw-CufXeDt4%3D&ved=0CEIQyjdqFQoTCIXSgduA9scCFYNcFAodK-kJzA&ei=qXf2VcXZB4O5UavSp-AM#imgrc=hntvsEI1dU7fsM%3A&usg=__oD-_CYD22FkwLpDaJw-CufXeDt4%3D
This is what the cable should be plugged into: https://www.google.co.uk/search?q=pci-e+cable&tbm=isch&imgil=hntvsEI1dU7fsM%253A%253BRlAvccc4fxbQDM%253Bhttp%25253A%25252F%25252Fwww.techpowerup.com%25252Fforums%25252Fthreads%25252Fquestion-on-my-psu-and-pci-6-2-pin-connector.202937%25252F&source=iu&pf=m&fir=hntvsEI1dU7fsM%253A%252CRlAvccc4fxbQDM%252C_&biw=1600&bih=788&dpr=1.2&usg=__oD-_CYD22FkwLpDaJw-CufXeDt4%3D&ved=0CEIQyjdqFQoTCIXSgduA9scCFYNcFAodK-kJzA&ei=qXf2VcXZB4O5UavSp-AM#tbm=isch&q=pci-e+cable+graphics+card&imgrc=1hBIhvT08reZ1M%3A

Look at the cable ends for one that says PCIe on it although, to be honest, it sounds like you have a cheap PSU so don't be surprised if you don't find one.

If your power supply does not have PCIe cables for a graphics card then it was not designed to do that job and you need to upgrade the PSU. They look like this-

tell us the exact make and model of the psu, you can then look it up on the manufacturers website which should list all the cables it has.
