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!

Gpus are backwards compatible. You won't get the full speed with an old motherboard but it won't be worse than the old card.

The PSU is a valid concern. You probably want to upgrade to a 700w. As long as it is at least gold rates you will be fine with almost any brand.

The CPU itself is still powerful, so from my perspective there is no need to go all out on a new system, just a new PSU. If you don't hit 60 in your favorite games at your preferred resolution with your preferred graphics level, only then should you consider upgrading.

If you can go more than 700w you should (especially for a 3090, I'd be looking at a 800w at least but would probably go for 1000w myself), you wont use more power than the system needs anyway, so there's no harm having the extra headroom for the future.
