Conclusion and Verdict
The power supply responded very well under full load. The load values were very tight. I was using a Intel 11900K with a RTX 3070. This combination is capable of drawing a lot of power. One of the biggest complaints about high wattage power supplies can be the size and this power supply has all this power packed into a small frame. You also get the fully modular feature that allows you to use only the cables you need. This is almost a necessity if you are needing to save space or want reasonable cable management. I am always concerned with keeping those internal components as cool as possible. The cooler those components the longer it will last.
Now for the big question will this power supply power the new cards? Yes, make sure you do your research and make sure you are able to meet the power requirements of your system when getting a new power supply.

One thing and the most important thing to remember when swapping out power supplies, IS NEVER REUSE CABLES FROM ANOTHER POWER SUPPLY! I would even caution this idea if its the same brand. I learned this the hard way in my past learning because I didn’t want to re-cable a case and come to find out some power supplies connectors vary brand to brand. Here is good explanation of what I am saying. Luckily when I did this I only lost some lights because the power supply was semi modular and that probably saved my mother board and CPU. Anyways take the time and use the cables that come with your power supply at all times!
