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!

    You might be able to get by with the power supply but 750+ watts is recommended for a 3090. Any B550 motherboard should be totally fine.

    For what it’s worth I’m running a 5950X, 3090, a pair of water pumps, and 11 fans all off a 750 watt Corsair PSU and I’ve never experienced any instability or signs of an insufficient PSU.

    If it were me in your situation, I’d just pick up a decent 750-800 watt PSU, and upgrade the memory to a decent 32 gig memory kit while I’m at it just to have a little better time. 3600mhz with decent timings seems to be the sweet spot. Otherwise, as long as the GPU fits the case, you should be in great shape to run it.

      Hard agree on investing on a more powerful psu, you always want headroom on wattage (and a good rating as well)

      I think OP means is that he has 4 8GB sticks for already a total of 32GB. While not quite as good as two 16GB sticks, it wouldn’t be worth the upgrade cost IMO. I’d say he just needs to upgrade the PSU and maybe replace the thermal pads/paste on his new used 3090 if he’s done that sort of thing before.
