A:

For gaming PCs, calculate your total power consumption and add 25% buffer. Typical gaming rigs need 1000-1200VA UPS. A high-end gaming PC (500W) + monitor (50W) + router (20W) = 570W total, so choose 1000VA minimum. Always go for pure sine wave to protect your expensive graphics card and PSU.

A:

Yes, it can cause permanent damage to LED monitors and modern SMPS power supplies. Modified sine wave produces irregular waveforms that can stress electronic components, cause overheating, and reduce lifespan. LED monitor manufacturers void warranty if damaged by modified sine wave. The extra ₹1,000-2,000 for pure sine wave is worth protecting your ₹15,000+ monitor.

A:

UPS batteries typically last 2-3 years in Indian conditions. Hot climate, frequent power cuts, and dust reduce battery life. Signs for replacement: reduced backup time (less than 50% of original), battery swelling, or frequent low battery warnings. Pro tip: Keep UPS in cool, ventilated area and perform monthly self-tests to extend battery life.

A:

Yes, always keep it plugged in. Modern UPS units have intelligent charging circuits that prevent overcharging. Keeping it unplugged will discharge the battery and reduce its lifespan. The UPS automatically switches between charging and standby modes. Only unplug during thunderstorms or extended travel to protect from lightning surges.

A:

No, never connect UPS input to extension cords or power strips. This can cause voltage drops, overheating, and fire hazards. Always connect UPS directly to wall socket. However, you can connect other devices to the UPS output sockets - that's what they're for. Use only the UPS manufacturer's recommended output capacity.

A:

VA (Volt-Ampere) is total power capacity, Watts is usable power. For computers, Watts = VA × 0.7 (power factor). A 1000VA UPS provides about 700W usable power. Always check both ratings - some devices have different power factors. Computer PSUs typically have 0.7-0.8 power factor, so focus on VA rating when sizing your UPS.

A:

APC offers superior software, build quality, and global reputation, but Indian brands like Luminous and Microtek provide excellent value with better local service networks. Choose APC for critical applications and if you need advanced monitoring features. For home computers, Luminous or Microtek offer 80% of APC performance at 60% cost with faster local service.

A:

Yes, especially for work from home setups. A small 600VA UPS can keep your router + modem running for 2-4 hours during power cuts. This maintains internet connectivity for mobile devices and enables you to continue video calls on laptop/phone battery. Many people overlook this but it's crucial for uninterrupted connectivity.
