Corsair CX 650 enough?

[bundejo]

I am upgrading some parts and want to know if 650w psu would be enough. I plan to reuse what I can(mid size case, cx650w, 212evo, r9 280 gpu).
My final build could look like this; b350 tomahawk, ryzen 5 1600x, 212evo cooler, 2x8ddr4 ram getting as close to 3200 as I can, 1ssd 120gb, 1tbh harddrive. I would like second monitor and possible crossfire a second r9 280 gpu. Is 650w psu enough to add second monitor and crossfire 2nd r9 280?

You'll want the CX (2017) or CXM (2015) version of that PSU, the older versions are junk. For a 280 CF you'll want a larger PSU, recommendation is 800W.

But tbh CF or SLI isn't worth it as driver support is pretty poor, just go with the single best GPU you can afford.

Yes, even CX550 is more than enough. Do you live in US? Can I ask why do you want to crossfire? Yes, 650 is very close call if everything is near stock level.

GPU is 200W *2
CPU is 95 W
rest is 50W
times 1.25 for headroom, 700+ is recommended.

CX650 is new grey label, CX600 is old junk.

I do live in the US. I am upgrading from fx-8120 and assumed my r9 280 would become a bottleneck with the ryzen 5 1600x. I was trying to reuse gpu, psu, and cpu cooler to get the most from the lower price with ryzen. Otherwise I think I go all in on Intel.

I play games like planetside 2 and Archeage

ryzen uses a thinner cpu dye essentially called lithography , so it's not as power hungary .

most games don't adjust well with crossfire. I will suggest selling 280 and buy a GTX 1060/1070 instead for the upgrade. In that case, 550 is more than enough. Remember to order AM4 mounting to use 212 evo.
