The EVGA P6 850W is a great high-capacity power supply, and today it’s been discounted by £30 over at Scan, dropping from £120 to £90. That’s a good deal on a PSU that meets the steep requirements of the RTX 4090, as well as Nvidia’s more sanely-specced RTX 40-series cards like the RTX 4080 16GB and the RTX 4070 4080 12GB.
