Quick Answer

Modern SA gaming monitors draw between 18W and 65W depending on size, panel tech and brightness. A typical 27-inch 1440p IPS used 8 hours a day costs roughly R20 to R45 per month at current Eskom and municipal tariffs, while loadshedding-friendly OLEDs trim that further at lower brightness. UPS sizing also depends directly on this number.

What SA Gamers Actually Pay To Run A Monitor

At around R3.50 per kWh in most SA metros for 2026, a 30W monitor used 8 hours a day works out to roughly R25 a month. A power-hungry 38-inch ultrawide pulling 60W tips that closer to R50. OLEDs are surprisingly efficient at moderate brightness because pixels switch off entirely on dark scenes, so a 27-inch QD-OLED running at 50% brightness can sit closer to 25W during gaming. Mini-LED panels with full local dimming pull more, often 45 to 80W, due to thousands of backlight zones running hard during HDR scenes.

Brightness, HDR And Refresh Rate

Brightness is the single biggest variable. Cranking your monitor from 30% to 100% can almost double power draw. SA gamers playing in well-lit lounges often run at 60 to 70%, which is the sweet spot for both eye comfort and electricity. HDR mode kicks in higher peak brightness and also raises consumption. Higher refresh rates only add a small amount of draw, so going from 60Hz to 240Hz on the same panel typically adds just a few watts. Always disable HDR on the desktop and only flip it on for content that supports it, otherwise you're paying for brightness you don't see.

Loadshedding And UPS Sizing

When Stage 4 loadshedding hits, your UPS keeps the rig running, and a smaller monitor draw stretches that runtime. Pair a 1,500VA UPS with a 30W monitor, mid-range PC pulling 250W under gaming load, and you'll get roughly 25 to 35 minutes of uptime, plenty to finish a Valorant round and shut down cleanly. Drop to a 65W mini-LED and that runtime shrinks. If loadshedding hits hard in your area, prioritise efficient IPS or efficient OLED panels and you'll save both rand and runtime.

Frequently Asked Questions

Does a higher refresh rate use much more power?

Not really. Going from 60Hz to 165Hz on an IPS panel typically adds just 2 to 5W. Brightness, panel tech and HDR mode are far bigger contributors than refresh rate.

Are OLED monitors worth it on SA electricity costs?

Yes. OLEDs run cooler and use less power on average gaming and desktop content compared to mini-LED, because dark pixels draw zero power. Just keep brightness reasonable to extend panel lifespan and your wallet.

How do I check my monitor's actual power draw?

A cheap inline power meter from any SA hardware shop costs around R250 to R400 and clamps between your wall socket and the monitor. Plug it in, run gaming, desktop and HDR content, and you'll see real-world numbers within minutes.
