I own a 700w Corsair PSU that’s nearly seven years old, running a Ryzen 5700X on an x470 board with 32gb RAM and a 3060 graphics card at stock speeds.
My setup includes four 240mm RGB fans, five short RGB strips, two SSDs, and one HDD.
The system is mainly used for art projects instead of gaming, so I chose the 3060 to get 12gb VRAM rather than raw performance.
Considering the PSU’s age, how much headroom remains for adding another graphics card?
I already have a 670 and a 1660ti, and I’m considering a second 3060 if it can support it. My motherboard and case have enough space.
I want to increase my VRAM further, as my software allows multiple cards to run smoothly. With enough power available, it should work well.

Check the Corsair 1000w PSU model details.
Refer to the reviews page for optimal sizing with multiple GPUs.
Aim for a general wattage range, but consider higher values if possible.
High wattage spikes with two GPUs might indicate instability.
If the component lists a wide range, choose the upper limit.
Be cautious of older PSUs; they may struggle under increased load.
A safe approach is to upgrade to a new unit.
At least understand the situation and its impact on your system.
Monitor performance closely for any issues.
