I'm considering adding an NVIDIA GeForce 9800 GT to my setup, which currently includes a Radeon RX7900 XTX, a Ryzen 7 7800 X3D, an MSI B650 Gaming + Wifi motherboard, and 32GB of DDR5 RAM. I'm wondering if my Corsair RM1000e 1000W power supply is sufficient for this additional low-power card. The main reason for this upgrade is that I'm a bit of a tech nerd and I want the native analog S-Video output for some CRTs. I know this is a super old graphics card, but I want to check if it's a bad idea before I jump into running two different GPUs on my rig!

You should be totally fine power-wise. That card only draws about 125 watts, so your 1000-watt PSU has plenty of overhead for it.
I think the biggest challenge here will be the drivers, not really the power. That card is pretty old school, so you might run into some quirks getting it to play nice with your newer graphics card.
You're definitely in the clear on power! Just keep an eye on the driver situation; that's where you might hit some bumps in the road.
You definitely won’t have a problem with power. But keep in mind, drivers could be a hassle, especially if you’re not running Windows 10 or earlier.
I'm on Linux, so I’m hoping to get it sorted with some tinkering! Sounds like a troubleshooting adventure, haha.
Have you considered running the 9800 GT off the integrated GPU? That might save some hassle.
I could do that! But I like this route better since it’s cheaper and should give a better video quality without the delay from digital to analog conversions. Plus, it’s just fun to experiment with tech!

Yeah, I'm expecting a bit of hassle too, especially since I’m on Linux. I picked this card specifically to avoid conflicts with the modern drivers since it’s a totally different brand.
