Would an older Seasonic M12D SS-850 work on today's gaming PCs?

Yes. If it has the required plugs it will work. I didn't click the link, didn't have to. If the PSU comes with at least 2 6 pin PCIe connectors (preferably 2x8pin), and an 8pin for cpu, no worries. 850w is more than comfortable.
 
Link shows two 6+2pin PCIe connectors. You're good to go.

I'm still using a PC Power & Cooling psu from 2007. You'll be fine.
 
My Thermaltake Toughpower 1000w is from 2007, and does a fantastic job with my X570+3900X setup using a RTX2080. A high-quality PSU that has been well cared for will last a VERY long time. I don't plan to replace my PSU until the ATX12v spec becomes obsolete.
 
yeah its fine. but since its really old, and out of warranty, id pop the lid, give it a good clean and make sure all the components are up to snuff.
