Builder’s Buying Guide: Fitting It Into Your Rig
Check Compatibility First
Before buying, make sure 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 much of the budget this deserves based on how hard heavy multitasking leans on the power supply, then choose 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 the build current for years.
