Builder’s Buying Guide: Fitting It Into Your Rig
Check Compatibility First
Before you hit buy, double-check the power supply matches your platform and the rest of your 2026 build — sockets, sizes, connectors, and clearances all have to add up.
Match It to Your Budget
Work out how big a slice of the 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 breathing room.
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.
