80 Plus Bronze, Gold, Platinum Explained
When building or upgrading a PC, your power supply unit (PSU) is crucial. The '80 Plus' certification indicates its energy efficiency, with ratings like Bronze, Gold, Platinum, and Titanium signifying how much power is converted into usable electricity versus lost as heat.
What is 80 Plus Certification?
80 Plus is a voluntary certification program that tests PSUs for efficiency at 20%, 50%, and 100% of their rated load. A PSU must be at least 80% efficient at all three load levels to receive any 80 Plus certification. Higher efficiency means less wasted energy, lower heat generation, and potentially quieter operation.
80 Plus Bronze: The Entry Point
Bronze PSUs are typically 82% efficient at 20% load, 85% at 50% load, and 82% at 100% load. These are a good budget-friendly option for basic systems or users not concerned with maximizing energy savings. You'll often find 80 Plus Bronze PSUs in the $50-$80 range for common wattages like 550W-750W.
80 Plus Gold: The Sweet Spot
Gold PSUs offer 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load. This tier provides an excellent balance of efficiency, performance, and price, making it popular for most gaming and enthusiast builds. A quality 750W 80 Plus Gold PSU usually costs between $90-$130, like the Corsair RM750e.
80 Plus Platinum: Premium Efficiency
Platinum PSUs boast 90% efficiency at 20% load, 92% at 50% load, and 89% at 100% load. These are ideal for high-end systems where every watt counts, or for users seeking the quietest possible operation due to less heat. Expect to pay $150-$200+ for a 750W 80 Plus Platinum unit, such as the Seasonic Focus PX-750.
80 Plus Titanium: The Best of the Best
Titanium is the highest certification, requiring 90% efficiency at 10% load, 92% at 20% load, 94% at 50% load, and 90% at 100% load. These PSUs are designed for extreme efficiency, often found in server environments or top-tier enthusiast builds. They come with a significant price premium, often $250+ for a 750W unit.
Key takeaways
