“What wattage power supply does this graphics card require?”

1-3 of 3 Answers

• A minimum of 300W or greater is the requirement. I just installed this card on (3/18/17) into my old dell XPS 8100 pc, to replace the factory ATI Radeon HD 5770- 1GB card,. which is seriously on the blitz My factory power supply unit is rated at 350W, and it's doing the job fine so far. I did purchase a 600W PSU along with the card for $49 just in case though, but it seems that I will be able to take it back for a refund. My old motherboard has a PCI Express 2.1 x16 interface connection, which accepts this cards PCI 3.0 interface, even though the pin spacing looks a little different, and It has a six pin power connection. I hope this info helps you.
