Quick Answer

In cheap gaming mice near expensive setups, the main switches develop double-click first, then the scroll wheel encoder and the cable wear out. Budget R500-R1,200 for a mouse with durable optical or rated mechanical switches, and protect the rig with a surge protector rather than expecting the mouse to deal with power.

What breaks first, in order

The left-click switch is the classic failure on a budget mouse: rated for far fewer presses than a quality unit, it starts registering one click as two, which is maddening in games and document work. Next the scroll-wheel encoder gets jumpy, scrolling the wrong way or skipping, and the rubberised cable cracks or the side grips peel. A cheap optical sensor can also stutter on certain mousepads. Power has nothing to do with these failures; the mouse just needs a protected PC behind it.

Build for longevity and protect the rig

Choose a mouse with optical switches or high-rated mechanical switches (often 50-80 million clicks), which sidestep the double-click problem that kills budget mice. A flexible paracord-style cable or a wireless model avoids cable fatigue, and a quality sensor like a PixArt-based one tracks reliably across surfaces. For the power-protection angle, a surge-protected multiplug (R300-R800) or UPS guards the PC and its USB ports from spikes, and the mouse plugged into the protected machine is covered.

Buying it in South Africa

Evetech ships mice and surge gear nationwide, so you can upgrade the mouse and protect the setup in one order. Budget R500-R1,200 for a mouse with durable switches and a good sensor, and add a surge-protected multiplug for the rig. Favour optical or high-rated switches and a flexible or wireless cable for the longest life, and size the surge protector to cover the whole desk.

FAQ

What breaks first on a cheap gaming mouse?

The main click switch, which develops double-click as it wears, registering one press as two. The scroll-wheel encoder and the cable are the next parts to fail on budget units.

Do optical mouse switches last longer?

Yes. Optical switches avoid the mechanical contact wear that causes double-click, and high-rated mechanical switches (50-80 million clicks) last far longer than the cheap switches in bargain mice.

Does a mouse need power protection?

No, not directly. It draws power from the PC's USB port, so a surge-protected multiplug or UPS guarding the whole system protects the mouse along with everything else on the desk.

TIP

or high-rated switches to dodge double-click, and guard the rig with a surge protector. The mouse never needs power protection of its own.
