I recently bought a refurbished computer (HP dc5800). Of course, it came without a graphics card. So, to make it possible for me to at least play SOME games, I purchased a used MSI 8800GT 512MB, stock overclocked (http://www.newegg.com/Product/Product.aspx?Item=N82E168...). Since I am somewhat of a noob, when it comes to upgrading computer parts, I did not know I would need a 6-pin connector to power it. The open connectors coming from my power supply are 2x SATA plugs, 1x molex plug, a very small white plug, and a bar-like black plug (another like it is connected to my hdd).
What I've been reading, is to get the molex-to-6-pin connector, but most of them require two molex plugs. Is there a connector out there that would make use of my single molex and multiple SATA connectors to power a six-pin connector?
Also, could I use the card without the 6 pin connector plugged in and only have the card connected to the PCIE port?
Replace the power supply and trust me it is worth it having something better than the stock unit. Far to many HP units have ended up needing new power supplies due to quality issues. A new unit that is high quality is not only good for upgrading but good for everything else that is there due to there being more stable current.
