The Sparkle Power SPI3001UH is a 300 W ATX12V switching power supply engineered for desktop PC systems and standard builds. It delivers regulated output across multiple rails with active Power Factor Correction and achieves up to 84% efficiency under typical operating conditions. The unit meets 80 PLUS energy efficiency standards and maintains an MTBF of 100,000 hours at maximum load and 25°C. Comprehensive protection circuitry guards against overcurrent, output overvoltage, and short-circuit faults. The compact 1U rackmount form factor (3.9″ × 1.6″ × 7.5″) accommodates space-constrained deployments while internal 120 mm DC fan cooling supports operation from 0°C to 50°C across 5% to 90% non-condensing humidity. RoHS compliance and dual-voltage input (90–264 V AC, 47–63 Hz) enable global deployment.
