Best Power Supplies (Price per Watt)

A quality PSU is the heart of your PC. We compare power supplies based on price per watt, efficiency, and modularity. calculate the true value of Gold and Platinum rated units to power your GPU safely.

How much wattage do you need?

As a rule of thumb, aim for 50-60% load for peak efficiency. For an RTX 4070 build, 650W is plenty. For RTX 4080/4090, target 850W or 1000W to handle transient spikes and future upgrades.

Efficiency Ratings

80+ Gold is the sweet spot for most gamers, offering ~90% efficiency without the premium price of Platinum or Titanium units. Avoid unrated units for gaming PCs.
