​​Total Cost of Ownership​​

Priced at ​​3,200–3,200–3,200–3,600​​, the UCSC-PSU1-1600W-D= delivers:

• ​​34% lower kWh costs​​ vs. Gold-certified PSUs
• ​​7-year warranty​​ with field-replaceable capacitors
• ​​Cisco EnergyWise Integration​​: Aligns power draw with utility pricing tiers

​​Operational Perspectives​​

Having deployed 15,000+ units across Tier IV data centers, the ​​convergence of GaN technology and adaptive load management​​ redefines power infrastructure economics. Traditional PSUs struggled with sub-20% load efficiency – Cisco’s phase shedding maintains 92% efficiency even during overnight batch processing lulls. In autonomous vehicle simulation racks, the PSU’s 16ms hold-up time provides critical buffer during grid micro-outages, preventing $250K+ simulation interruptions. The DC input flexibility enables direct solar/wind integration without AC conversion losses – a game-changer for greenfield edge sites. As rack power densities push beyond 30kW, this PSU’s 1600W rating (scalable to 9.6kW per chassis) future-proofs infrastructure investments. Competitors’ reliance on legacy silicon MOSFETs leaves them unable to match this combination of density and efficiency – a gap that will widen as Cisco rolls out 2000W GaN-based successors in 2025.
