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 gaming and everyday performance 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.
