Which 850W power supply is the best choice for my RTX 3080 build?
Asked by

I'm putting together a system with an RTX 3080 12GB and a Ryzen 5 5500X3D, and I need help choosing the best overall power supply. The options available to me at roughly the same price are the Thermaltake Toughpower GT 850W, NZXT C850 Gold Core, MSI MAG A850GL PCIE5, Thermalright AG850, and DeepCool DQ850M V3L. These are the only reasonably priced choices I could find locally, so I'd also appreciate knowing about any important caveats, such as cable configuration, compatibility, or reliability concerns.

The NZXT C850 Gold Core would be my pick. It has a good reputation, solid build quality, and nicely made cables. The MSI is also a reasonable option, but check the included PCIe cable layout because it may provide fewer separate GPU cables than you’d prefer for an RTX 3080.

The NZXT and DeepCool units are the strongest choices from this list. Both are generally regarded as high-tier models, so I’d choose whichever is cheaper or has the better local warranty. Since the NZXT costs only a little more, it may be worth paying the difference if you prefer its cables and availability.

The MSI MAG A850GL PCIE5 should also work well with this hardware, and the GL series is generally a safe choice. Just verify that you can connect the graphics card using the recommended separate PCIe power cables rather than relying on a single daisy-chained cable.
