Question about upgrading graphics card
Question about upgrading graphics card
I built this PC around 2022 focusing on gaming, and then needed a suitable Nvidia GPU for AI tasks. A chance came up when I found the "ASUS NVIDIA GeForce RTX 5090 TUF Gaming Triple Fan 32GB GDDR7 PCIe 5.0 Graphics Card." There weren’t many concerns at first.
Welcome to the forums, newcomer!
Consider exploring a 1.2KW~1.5KW PSU;

The discrepancy you're seeing likely comes from different specifications or components being referenced. The partpicker might show an estimated wattage, while the ASUS documentation provides a higher value. There isn't a strict rule, but factors like component efficiency and system configuration can influence these numbers.
Your system's RAM might be the least impressive part, but you have limited options without a complete overhaul. 5800X3D matches a 9600X nicely, which should handle gaming well. For 1440p, a 5090 should suffice, though a quicker CPU would boost FPS even more. With a 4K display, the CPU's performance becomes less critical.
You'll likely need a better power supply. A minimum of 1000W is recommended, and upgrading to 1200W won't be too costly. This isn't just about gaming; an AI task will strain the GPU for long periods. Keeping the PSU under 80% output is important, as a 850W unit could overload the system when the GPU runs at full capacity.

Imagine the system operating at maximum capacity. A 600W GPU, 105W CPU, motherboard, memory, cooling fans, and storage drives could easily reach 800W. With a 1000W power supply, the load would be around 80%. A 1200W supply would bring it to 66%, and a 1350W supply to 59%. As the load increases, the fans become noisier, and higher temperatures can reduce the lifespan of components.
Confirming, I'm checking if you mean RAM when you refer to memory.
I added several links in my first message. Besides the big spikes in power demands from the RTX 3000 line, you can trust the figures shared on TechPowerUp. I usually check a few sources and then adjust the numbers to give myself extra margin when buying a PSU. This ensures the device stays under its limits when powered by electricity and helps it operate cooler, which also extends its lifespan.
Keep in mind that power rating isn’t the only factor to consider while choosing a PSU. You should also think about durability and long-term performance.
I understand. Others have suggested the ATX 3.1 option too. I'm considering the MSI - MEG Ai1300P and want to make it future-proof since I plan to upgrade other components later. Are there any issues with that approach?
