Hey everyone! I'm in the process of building a new PC and I want to ensure that my power supply unit (PSU) is adequate for my setup. I'm considering the Lian Li Edge 850W 80+ Gold and I'm particularly concerned about power draw, especially with the current GPUs and all the RGB fans I have. I might choose to upgrade my PSU when next-gen GPUs come out, so I'd love your input on this. Here are my specifications:
- **Motherboard:** MSI X870E EDGE TI WIFI
- **CPU:** AMD Ryzen 7 9800X3D (not overclocked)
- **Cooler:** Lian Li Hydroshift 360S AIO
- **RAM:** Corsair Dominator RGB 64GB (2x32GB)
- **GPU:** Colorful iGame RTX 5080 Ultra
- **Storage:** 2x M.2 NVMe SSD and 1x 7200 RPM HDD
- **Case:** Lian Li O11 Dynamic EVO RGB
- **Fans:** 10x Lian Li UNI FAN SL-INF 120 RGB and 3x Lian Li TL LCD Fans
- **Extras:** Lian Li Strimer RGB 24-pin + 12VHPWR GPU cable

Honestly, 850W should technically work for now, especially if you're not overclocking your CPU. Just keep in mind that during heavy loads, it might be pushing the limits, especially with all those RGB components. If you're looking for headroom and considering future upgrades, it might be worth investing in a higher capacity PSU now instead of later.
For the RTX 5080, it's generally recommended to have around 950W for optimal performance, especially considering the GPU's total board power (TBP) of around 360 watts. Since your Ryzen 7 9800X3D draws about 170 watts, that leaves around 280 watts spare, which isn't a lot given all your RGB fans and the potential for higher power draw. Even though your PSU is high-quality, I wouldn’t risk going under 950W if you're looking to future-proof your build, especially if you plan to upgrade to a more power-hungry GPU later on. Definitely reconsider the wattage just to be safe!
I see your point! But just to clarify, since he’s using an AMD CPU and not an Intel, would the power draw estimates still apply or would they be different?
