A client wants to purchase a power supply unit with the highest possible energy efficiency rating for a green data center build. Which 80 PLUS certification level should the technician recommend?
- A80 PLUS White
- B80 PLUS Bronze
- C80 PLUS Silver
- D80 PLUS Titanium
Show answer & explanationAnswer & explanation
Correct answer: D. 80 PLUS Titanium
The 80 PLUS certification tiers, from lowest to highest efficiency, are White, Bronze, Silver, Gold, Platinum, and Titanium. Titanium requires the highest efficiency percentages at all load levels, making it the best choice for maximum energy efficiency.
Why the other options are wrong
- A. White is the base/lowest certification tier.
- B. Bronze is a mid-low tier, less efficient than higher tiers.
- C. Silver is higher than Bronze but still below Gold, Platinum, and Titanium.
80 PLUS PSU Ratings
80 PLUS certification measures a power supply's energy efficiency at various load levels, with tiers ranging from White (lowest) to Titanium (highest).
- Order: White < Bronze < Silver < Gold < Platinum < Titanium
- Higher tiers waste less energy as heat
- Titanium requires ~90%+ efficiency across most loads
Memory trick: Winning Bronze Sprinters Go Platinum Then Titanium (climbing tiers)
