How to Choose the Right PSU for Your Gaming PC in Sri Lanka

Power Supply Unit (PSU) Buying Guide for Sri Lankan PC Builders

The PSU is one of the most underrated but most important components in any PC build. A poor-quality PSU can damage your entire system. This guide helps Sri Lankan PC builders choose the right PSU for their gaming rig in 2025 — and where to buy one with confidence.

How Much Wattage Do You Need?

Add up the TDP of your CPU and GPU, then add 20–30% headroom. Common recommendations for 2025 builds:

RTX 5060 + Core Ultra 5 build: 550–650W PSU recommended.
RTX 5060 Ti + Core Ultra 7 build: 650–750W PSU recommended.
RTX 5070 and above: 750W–850W PSU minimum.
RTX 5090 builds: 1000W+ PSU required.

80 Plus Efficiency Ratings Explained

PSUs are rated by their efficiency at converting AC power to DC. In Sri Lanka’s hot climate, efficiency matters even more for heat management. Ratings from lowest to highest: 80 Plus White, Bronze, Silver, Gold, Platinum, Titanium. We recommend at least 80 Plus Bronze — ideally Gold — for any gaming PC build.

Modular vs Non-Modular PSUs

Modular PSUs let you only connect cables you need — resulting in cleaner cable management and better airflow. Semi-modular PSUs have some fixed cables. Non-modular come with all cables attached. For a clean-looking build, go modular or semi-modular.
