Hello, I have a dell optiplex 9020 and I added a new video card to work with three monitors.
The video card states it requires 400w power supply. The video card does NOT have a power connection, it gets all of its power from the pci-e16 connection.
The dell power supply in the unit is 290w and it has a P1 and P2 connector. The sata drives are powered through the mother board rather than directly from the power supply. The power supply only has two connectors, one for the mother board and the other for the cpu.
I called Dell and the tech did not appear to know what to tell me when I asked which power supply I should purchase in order to support the video card. He essentially said the mother board does NOT recommend a power supply larger than the power supply in the unit and that if I wanted to add more monitors I should purchase dell parts.
Can anyone provide advise.
