I am doing a new build with an Antec Sonata III case that included a 500W Earthwatts PSU (model EA-500D). I am pairing this with a Gigabyte GA-EP45-DS3L motherboard. I am trying to install a Sapphire HD 4870 w/ 1 GB vram. When I power up the system I do not have any display at all, and I have three red LED lights appearing, labeled D1601, D1602 and D1603. Googling this seems to indicate a power problem but I think my PSU is enough to power this card. The only other equipment connected to the PSU is an E8500 with the stock cooler, a DVD drive, a single hard drive, and one case fan.
My biggest question is how to connect this video card to the PSU. The power supply only has one PCI-E power plug. The Sapphire card came with two cables that appear to be adapters to connect the six pin connection of the card to the standard four pins of the PSU. I have tried using both cables and I have also tried using the PCI-e power cable from the PSU in one connection and the adapter cables that came with the card for the other connection. In both instances I do not have anything displaying on the screen (the light stays amber so the monitor never even "wakes up") and I have the three red LED lights.
Any insights?
