Builder’s Buying Guide: Fitting It Into Your Rig
Check Compatibility First
Before pulling the trigger, double-check the power supply suits your platform and the rest of your 2026 build — sockets, sizes, connectors, and clearances all have to line up.
Match It to Your Budget
Work out how big a slice of your build budget this deserves based on how hard high-FPS esports leans on the power supply, then settle on the tier that weighs cost against headroom.
Plan for Upgrades
A sensible power supply pick leaves headroom to grow, so go with one that won’t choke a later upgrade and keeps your build useful for years.
