Title pretty much tells you all you need to know about my situation. In a turn of events tonight I’ve been gifted a used but working EVGA 3090 card to replace my seven year old 1070.

My current system hardware specs are:

CPU: AMD Ryzen 9 5900X 12-Core (upgraded from Ryzen 5 last year)

GPU: MSI 1070

MoBo: MSI MAG B550 TOMAHAWK

PSU - Corsair CX-550 550 Watt

x4 8GB Installed Memory

I also have a 2tb SSD drive with my OS and games installed, and 4 8tb HDD for media.

My main concern is with needing to replace my MoBo with a x3 PCi board and worries about my PSU not being powerful enough. I’m not particularly worried about my tower is a Phanteks Enthoo Pro PH-ES614PC_BK.

Thanks in advance!

    Assuming you have the right power connectors, don’t exceed the max draw from the PSU, and that the card will fit, you can use a newer graphics card in the older PCIE slot. You’ll take a performance hit for doing so. The major difference in slots is the bandwidth. You end up not being able to push enough data to the card to fully utilize it.

    The PCIe standard is both backward and forward compatible between generations.
