About Power Supplies at Pro Disk Network

Choosing power supplies for an enterprise deployment is rarely a single-axis decision — compatibility, warranty tier, lead time, and total cost of ownership all matter. The reference content below summarises Pro Disk Network's pre-sales guidance for power supplies buyers.

Buying considerations for Power Supplies

• Calculate total connected load + 30% headroom (in VA, not just W)
• Online double-conversion vs line-interactive - online required for sensitive equipment
• Form factor - 1U/2U rackmount, tower, or modular cabinet
• Runtime target at full load - 5-15 min for graceful shutdown, longer needs battery extension
• Replace UPS batteries every 3-5 years - capacity halves below 80% charge retention
