I wouldn't recommend it, either regarding the power supply or regarding gaming performance. Crossfire (and SLI) has issues, so even though the raw performance is great, your in-game experience often won't reflect that.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

If you’re overclocking definite not. If you are not 750 might be just enough. But in the first place I would not recommend crossfire you would probably be better off getting a Rex Vega 5700 xt

If you want Radeon, just buy RX 5700 XT as it's RTX 2070 level. Multicard setups are always very picky and problematic. I always stick with single card setup and never ever had any major problems with Radeon or GeForce. It just works. Dual Vega 56 might give you great performance in some games and Vega 56 performance in others if things aren't optimal.

 

As things stand right now, I'd suggest waiting till July 7th when RX 5700 XT comes out. And NVIDIA with their "Super" cards.
