Quick Answer

For deal hunters, the VA rating is where bargains mislead most, because a big VA number can hide a low true watt rating. Always convert: a "1,500VA" special may only deliver 600W to 700W instead of 900W, which leaves a 400W PC with thin headroom. Compare rand-per-watt, not rand-per-VA, to find the real deal.

Why VA Alone Misleads On A Discounted UPS

VA is apparent power and looks impressive on a price tag, but watts is what runs your PC. The relationship is the power factor, and budget units often have a worse one, so a 1,500VA bargain might deliver only 600W to 700W rather than the 900W a better-specced 1,500VA unit gives. For a deal hunter, that gap is the trap: two units share a VA number but protect very differently. Find the watt rating before you judge any UPS special.

The smart comparison is rand per usable watt and rand per minute of runtime at your load, not the headline VA figure the discount is built around.

How To Read VA On A Deal Sheet

Check three things on any UPS special: the true watt rating (aim for 900W on a mid-range PC), the power factor if listed (higher is better), and the runtime chart at your wattage. A 1,500VA unit rated for a genuine 900W near R2,200 beats a 1,500VA unit rated for 650W at R1,800, because the cheaper one runs near its limit on a real gaming load and gives less runtime.

Buy Watts, Not Sticker VA

A deal hunter wins by ignoring the marketing VA and buying the watts and runtime that match the PC. The slightly pricier unit with the honest 900W rating is the genuine bargain; the cheaper big-VA box that only musters 650W is not.

FAQ

Why is the VA rating misleading on cheap UPS units?

Because watts, not VA, runs your PC, and budget units often have a worse power factor. A 1,500VA bargain may deliver only 600W to 700W, far less protection than a better 1,500VA unit's 900W.

How should I compare UPS deals?

By rand per usable watt and runtime at your actual load, not by the headline VA. A unit rated for a true 900W beats a cheaper one that only reaches 650W on the same VA.

What watt rating should a mid-range gaming PC's UPS have?

Around 900W gives a 400W to 450W build comfortable headroom. Confirm the watt figure on the spec sheet rather than trusting the VA sticker.

TIP

UPS special, convert VA to watts before buying; a true 900W unit at a slightly higher price beats a big-VA bargain that only delivers 650W.
