Issue with the Radeon HD 5770 Tags: Graphics Cards Power Supplies Radeon Graphics Last response: February 14, 2010 1:04 AM in Graphics & Displays Share Leopardson February 14, 2010 12:43:41 AM Hi, I purchased a Radeon 5770. Stupidly, I forgot to check and make sure my power supply is compatable. It turns out that my power supply does not have a 6-pin PCI-Express connector. However, a slip of paper came with my card that appeared to claim it can be used with a variety of pins including 1x4. If I plug a 4-pin connector to one of the rows 3-pin rows (So one pin sticks out) will the card work? Can doing so cause damage to my power supply? If not, will a 4-pin to 6-pin adapter from somewhere work so I don't have to pay for a new power supply? Also, on a different note: Should a 550-watt power supply be able to handle an AMD Athlon II x4 620, 4gb DDR2-800 and a Radeon 5770?

The 5770 should come with a 4pin molex to 6pin pcie power connector for you to use. http://www.newegg.com/Product/Product.aspx?Item=N82E168... It is recommended that your psu have the 6pin built in but it wont kill you to use a converter either. Leopardson February 14, 2010 1:04:17 AM unfortunately, there wasn't one in the box. It's a Diamond 5770 1gb GDDR5. All it came excluding packing material was the card, a SLI connector & a DVI adapter of some sort. I guess I'll have to buy an adapter. Can't find your answer ? Ask !
