Best Power Supplies for Gaming PCs in 2026

The Corsair RM750e at around $88 is the right PSU for most builds up to a RX 9070 XT or RTX 4070 Super. The Seasonic Focus GX-850 carries a 10-year warranty and is the better choice for high-end builds with the RTX 5080. Always buy fully modular for easier cable management. 80 Plus Gold is the minimum efficiency rating worth buying. See the full PSU guide.
