Out-of-touch old gamer looking for 3090-compatible components (lemmy.world)

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!

Everything looks more than good except that PSU as others mentioned. 750 should be okay, I'd try to get 850 or 1000 if you can afford the extra amount.

The 3000 series is known for transient spikes that can trip OCP on power supplies that can deliver the needed wattage. Obviously don't cheap out on a no-name or low quality unit. 5900X is more than enough today, and you've got plenty of RAM. Motherboard I wouldn't consider a concern either, put that money into the PSU instead.
