Integrated graphics card upgrade power supply problems

[Keane_feehan14]

My computer has integrated graphics but a slot for an upgrade. However my psu doesn't have any cables to power another graphic. I've already order a sapphire amd radeon hd 7770 for a small upgrade but I'm not sure u can power it. What can I do ???

you will need to get a new power supply the original probably isn't big enough
