Let's see if the computer is equipped with a power supply to drive it.

The i5 2300 is fully loaded with 95W, the HD6970 is fully loaded with 250W, and the main engine is fully loaded with about 380W. Among them, the sum of full-load power of CPU and graphics card is nearly 350W, and the output power of Hangjia multi-core R85 is 384W, which is just enough. Plus the power consumption of other accessories in the host, this power supply has no margin. In addition, the maximum current of 12V 1 of R85 is only 18A, which means that the maximum power provided to the graphics card is only 2 16W, and the HD6970 with a full load of 250W will be more difficult.

So, if the machine is equipped, use it. If not, I suggest changing the power supply. The same price is more than 400 yuan, so it's better to replace it with Aetna's VP550, with rated output power of 550W, 12V, 540W, 12V 1, and the maximum current is 30 A. It's no problem to bring your machine. If the funds are still sufficient, you can add 100 to replace it with Zhenhua overclocking Kingdee 450W, rated at 450W, 12V output power of 444W, and 80plus gold medal. Up to 90% conversion efficiency will save you a lot of electricity.
