I'm wondering if it's safe to install an RX 6400 graphics card in my system. I'm running a Fujitsu ESPRIMO P758/E85+ with an i5-8400 processor, 16GB of DDR4 Samsung RAM, a 256GB M.2 SSD, and Windows 11. My power supply is a 210W 80+ bronze unit. Will the RX 6400 work without issues?

You can run it safely since the RX 6400 typically only consumes around 50 watts from the PCIe slot. However, I’d suggest looking into the GTX 1650 because it works better with PCIe 3.0, which is what your CPU supports.
Yes, you can definitely use the RX 6400. Just keep in mind that the i5 8400 only supports PCIe 3.0, which will limit the card’s performance by about 25% or more since the RX 6400 is set up for 4x PCIe lanes. If you're looking for something solid without that performance hit, you might want to consider a GTX 1650 instead. The GTX 1650 Super is a better choice, but just check if you can find one that doesn’t need a PCIe power connector.
