The new Nvidia RTX 3090 Ti GPU is a powerful graphics card that will add some real firepower to your PC. However, a good power supply is required to run this beast of a GPU. The question is, will a 850w power supply be enough for the 3090 ti?
The answer to this question is a bit complicated. The RTX 3090 Ti requires a power supply that can handle its average and peak consumption. While the average consumption is low, the peak power consumption can be quite high. This is why it is important to know how much your power supply can handle before you purchase this GPU.
In general, a decent 850W power supply should be sufficient for this GPU. However, it is important to check if your power supply can handle the transient power spikes that this GPU is known for. You can do this by simply calculating the total amount of current that your power supply can deliver to your GPU using its 12v rails. You can do this by looking at the wattage and amps of your power supply, or simply searching online for a calculator.
If you want to avoid any problems with your GPU, it is a good idea to get a more powerful PSU than 850W. This will ensure that your PSU can handle any sudden surge in power that the GPU may need during gaming. Moreover, a bigger PSU will also provide plenty of power for other hardware in your system. This includes your CPU, RAM, and HDDs.
