Buying advice

For sensitive electronics like gaming PCs or audio equipment, a pure sine wave UPS is essential. Look for VA and watt ratings that cover your total load plus 30% headroom. Consider runtime needs for your devices. Brands like APC, CyberPower, and Tripp Lite are reliable. Budget models may use simulated sine wave, which can cause issues with some PSUs.
