Most first-time builders either overspend on a PSU they don't need or underspend and risk frying their system. Here's the cheat sheet:

The Rule: Add up your GPU TDP + CPU TDP + 100W (for everything else), then add 20% headroom.

Budget build example:

• RX 7600 → 165W

• Ryzen 5 7600 → 65W

• Rest of system → ~100W

• Total: ~330W → Get a 550W PSU ✅

Mid-range example:

• RTX 4070 → 200W

• Ryzen 7 7700X → 105W

• Rest of system → ~120W

• Total: ~425W → Get a 650W PSU ✅

Common mistakes:

❌ Getting a no-name 700W PSU for $25 — wattage ratings mean nothing without 80+ certification

❌ Skipping headroom — your system pulls more under peak load than you think

❌ Buying way too much — a 1000W PSU for a budget build is wasted money

We list the exact PSU requirement on every single component we sell. No guesswork.
