Protecting Rigs Against Indian Power Cuts

Sudden electricity cuts without a Uninterruptible Power Supply (UPS) cause instant PC shutdowns, corrupting NVMe SSD boot sectors and ruining unsaved work or competitive gaming matches.

1. Calculating VA Sizing (Power Factor 0.6)

A gaming PC consuming 450W power under full load requires a UPS rated for at least 1100VA / 660W (e.g. 450W / 0.6 = 750VA minimum). High-end RTX 4080 rigs require a 1500VA / 2200VA UPS.

2. Pure Sine Wave vs. Active PFC PSUs

Modern gaming power supplies with Active PFC require a Pure Sine Wave UPS (like APC Back-UPS Pro Line-Interactive) to prevent shut-off tripping during sudden utility transfer.
