Electricity Backup/UPS for Gaming PC

[Afnan Mir]

Hi, I have zero knowledge of UPS but want one for my PC. Following are the specs and I would like at least 1.5hrs of backup time.
32 inch 165hz display
2070
16GB RAM
i7 8700k
650w

Please tell me of the cost; UPS and batteries I need to buy.

buy apc brand
its line interactive pure sine wave technology
1500va/980 watts will be ok
model is sua1500i
works with 2 batteries

Hi Afnan,

- First find out what is your power draw
-Power draw varies with workload, most accurate way to measure would be with a watt meter

-If you don't have a Watt Meter then calculate your PC's wattage from this PSU Calculator according to your FULL specs
-Add the wattage of your monitor (should be on its back sticker)

-Use this UPS Selector to find out what's best suited for your load/back-up time
-APC are one of the best UPS makers for sensitive electronics like PCs but they have a vast line-up from cheap home use to professional grade.

-There are 3 basic types of UPS (read here)
-Offline
-Line-Interactive
-Online

-Your first requirement would be to get a UPS that can take up your load and provide required back-up time, second; If you can afford it, go for Online UPS as explained in "read here"

I will share my experience for reference, maybe it will help you decide. I have an APC SMT1500i (1000 Watts / 1kW) (Online, Pure Sine Wave) (5 button version) (24 Volts) (2 Internal OEM Batteries) on a Ryzen 3900X/GTX 1070 PC with a 55" LED TV and some routers connected to it and my power draw is from 284 Watts at normal browsing to over 600 Watts at full load. Backup time at 284 Watts is 51 mins and at 600 Watts is around 17 mins.

If you want more backup time than you can go for SMT2200i which is a 2000 Watts / 2kW, 48V UPS (4 batteries) or you can get a modded SMT1500i which can take on any external Lead-Acid / Dry Cell batteries. Modded APC UPS are very common, the batteries that go inside the APC UPS are Dry Cell batteries and are around Rs.5000/- EACH, for that amount of money you can get higher capacity external batteries.

I got my APC SMT1500i about 2 years back for around 18K + batteries for around 9.6K. These are used, imported UPS which are refurbished OR even repaired here to be sold, so beware and buy from a known person.

Hope this helps, best of luck.

To determine the appropriate UPS (Uninterruptible Power Supply) for your PC setup, you'll need to consider the power consumption of your components and the desired backup time. Here's a general guide to help you calculate the required capacity:

1. Calculate Power Consumption:
   • Display: Power consumption varies, but let's assume around 50 watts for a 32-inch 165Hz display.
   • GPU (2070): Approximately 175 watts.
   • CPU (i7 8700k): About 95 watts.
   • Other components: Estimate about 50 watts.
   • Total power consumption: 50 (display) + 175 (GPU) + 95 (CPU) + 50 (other) = 370 watts.
2. Determine Backup Time:
   • You mentioned you want at least 1.5 hours of backup time. Keep in mind that the higher the backup time, the larger the UPS capacity (measured in Volt-Ampere or VA) you'll need.
3. Calculate UPS Capacity:
   • The formula for UPS capacity is: UPS VA rating = Power consumption (watts) / Power factor.
   • Power factor is typically around 0.7 for computers.
   • UPS VA rating = 370 watts / 0.7 = 528.57 VA.
   • Round up to the nearest common UPS capacity; for example, consider a 600 VA UPS.
4. Select a UPS:
   • Look for a UPS with a capacity close to or above the calculated value (600 VA in this case).
   • Consider reputable brands such as APC, CyberPower, or Eaton.
5. Battery Backup Time:
   • Check the specifications of the UPS to see the estimated backup time at your calculated load (370 watts). Adjust settings if needed.
6. Cost:
   • UPS costs vary based on brand, capacity, and features. A decent 600 VA UPS might cost anywhere from $70 to $150, depending on the brand and additional features.

Remember that these are rough estimates, and actual power consumption can vary based on specific components, usage patterns, and efficiency. It's always a good idea to check reviews and specifications for specific UPS models to ensure they meet your requirements.
