80 PLUS Platinum Efficiency

80 PLUS Platinum requires ≥90% efficiency at 20% load, ≥92% at 50% load, and ≥89% at 100% load (115 V AC). Platinum PSUs use synchronous rectification and advanced capacitor layouts to achieve higher efficiency over Gold-rated units. They are common in premium gaming builds and workstations where efficiency and acoustics are prioritized. Seasonic and be quiet! produce some of the most respected Platinum-rated PSU lines.
