A gaming PC is the load people most often under-size a UPS for. A mid-range build idles politely at 120 W and then pulls four times that the moment a game loads — and it is exactly during that spike that a marginal UPS drops the load. Size for the peak draw of the graphics card, not the idle figure, and you get a machine that rides out Indian power cuts without a hard reset.

What draws power in this setup
Typical figures for Indian installations. Use the actual rating on your equipment where you have it — these ranges are for planning.
| Equipment | Typical draw |
|---|---|
| Entry gaming PC (60-class GPU) | 200 – 300 W peak |
| Mid-range gaming PC (70-class) | 350 – 450 W peak |
| High-end gaming PC (80/90-class) | 500 – 750 W peak |
| Gaming monitor (144 Hz, 27") | 30 – 60 W |
| Second monitor | 20 – 40 W |
| Router + modem | 15 – 30 W |
What size UPS you need
| Your total load | Recommended UPS | Why |
|---|---|---|
| Up to 350 W peak | APC Back-UPS 1100VA | Entry build, one monitor and the router. |
| 350 – 550 W peak | APC Back-UPS Pro 1000VA | Mid-range build — Pro models handle the spikes better. |
| 550 – 850 W peak | APC Back-UPS Pro 1500VA | High-end GPU, dual monitors and networking. |
| Above 850 W peak | Talk to us | A 1500VA Pro is the practical ceiling for a home socket; beyond it we would size differently. |
How the numbers work: UPS VA ratings in these families assume a 0.6 power factor, so a 1100VA unit supports roughly 660 W. Size for peak draw plus about 30% headroom, not for average use.
Which type of UPS
Line-interactive Back-UPS is the right choice for almost every gaming build. Step up to an online UPS only if you are also protecting a streaming or workstation setup you cannot afford to drop.
Genuine APC units we stock for this
All prices are GST-inclusive and every unit ships with the full APC manufacturer warranty and a GST invoice.
Read the GPU, not the PSU
Do not size from your power supply's rating — an 850 W PSU does not draw 850 W. Size from what the machine actually pulls: roughly CPU peak + GPU peak + 80 W for everything else. A 650 W actual peak needs about 850 W of headroom, which is roughly a 1500VA UPS at a 0.6 power factor.
Keep the router on the UPS
Backing up the PC but not the router means the machine survives the cut and still loses the match. The router and modem together draw under 30 W — there is no reason not to put them on the same UPS.
The battery, three to five years from now
Every UPS eventually needs a new battery, and this is where buying from an authorised partner pays off. A genuine APC RBC replacement battery cartridge typically lasts 3 to 5 years. When yours is due, enter your model in the Battery Finder and it will show the exact cartridge that fits, with live pricing — or check the battery replacement chart.

Frequently asked questions
What size UPS do I need for a gaming PC?
Size from peak draw, not idle. An entry build with one monitor is comfortable on an 1100VA Back-UPS; a mid-range build wants a 1000VA Back-UPS Pro; a high-end GPU with dual monitors wants a 1500VA Back-UPS Pro. Send us your CPU, GPU and monitor and we will confirm.
Will a UPS let me keep gaming through a power cut?
For a few minutes, yes — long enough to save, quit cleanly and shut down, which is the point. A UPS is protection against losing work and against the hard resets that shorten a machine's life, not a substitute for a generator or inverter.
Do I need a pure sine wave UPS for gaming?
Modern PC power supplies with active PFC are happier on a pure sine wave, and some will complain audibly or refuse to transfer on a stepped waveform. If your build has a good active-PFC supply, prefer a Back-UPS Pro or an online unit. Tell us the PSU model and we will tell you.
Is a UPS or a stabilizer better for a gaming PC?
They solve different problems. A stabilizer corrects high or low voltage but gives you nothing during an actual cut. A UPS gives you battery backup and surge protection. In most Indian homes the UPS is the one you need; add a stabilizer only if your supply voltage swings badly.
