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, dimensions, connectors, and clearances all have to match up.
Match It to Your Budget
Work out how big a slice of your budget this deserves based on how much gaming and everyday performance relies on the power supply, then settle on the tier that weighs cost against future headroom.
Plan for Upgrades
Picking the power supply wisely means leaving headroom to expand, so go with one that won’t choke a later upgrade and keeps your rig viable down the road.
