Pros & Cons

Pros

  • ✓ Pure sine wave output at 1500VA / 900W for servers, switches and routers
  • ✓ Eight NEMA 5-15R outlets, including a switchable outlet group for separate power control
  • ✓ AVR corrects high and low voltage, helping preserve battery life

Cons

  • ✗ SmartConnect is only a 6-month free trial for units bought after Aug 1, 2023
  • ✗ 900W real-power cap limits it for high-draw gaming PCs with power-hungry GPUs
  • ✗ Runtime at load isn't listed; check APC's runtime chart before sizing
  • ✗ Line interactive, not online double-conversion, so it switches over briefly during outages

One switchable outlet group lets you control power to selected devices separately. APC…
