Upgrading Graphics Card and Power Supply

[HunterHyena]

I have a HP Pavilion HPE H8-1214.

I bought a GTX 550ti graphics card for it.

When I went to install it, it fit in the PCI slot. However the power connectors did not fit. The ones that are on my pc are SATA power cables and the ones that are needed for the graphics card are the 4 pin peripheral power cables. What is the cheapest/easiest way to get the proper connectors so I can use this graphics card? Also what is a good brand for a 500w Power Supply to run the graphics card? (My computer only has 300w and the minimum is 400w)

^ Solid choice, I'm rather partial to Antec as well.

A quality power supply will have at least one and possibly two of the 6pin connectors attached to it. The 550Ti only requires a single 6pin according to the specs, so you should be fine.
