Discover our range of ASUS Power supplies

Stable power makes a fast PC feel effortless. ASUS power supplies aim to deliver that stability with efficient conversion, quiet cooling, and tidy cabling, from mainstream units through to high-wattage models for multi-GPU or creator rigs.

The core benefit is clean, reliable power delivery. Look for 80 PLUS ratings to gauge efficiency, modular cabling to keep cases uncluttered, and semi-passive fan modes that switch the fan off at low loads so your system stays quiet while browsing or editing documents. ASUS's enthusiast lines add premium bearings and long warranties to underline longevity.

Hero feature for builders: fully modular designs. Only plug in the cables you need, route them cleanly, and leave the rest in the box, which improves airflow and makes future upgrades easier. Many units also include compact housings that fit smaller cases while still offering modern connectors for graphics cards and motherboards.

Selection tip: size your PSU with headroom. Add up the estimated draw of your CPU and GPU, then choose a wattage that leaves 25-40 percent spare so the unit runs in its most efficient, quiet range. Keep the intake filter clear and give the back of the case a little breathing space to help the fan work at low speed.

For exact connector counts, cable lengths, and warranty terms, see the product pages and check Currys for current stock across different wattages and series.

What wattage PSU should I buy?

Match it to your parts and leave some headroom. Mid-range gaming systems are often comfortable around 650-750 W, while high-end builds or heavy creator rigs may need more.

What does 80 PLUS mean?

It is an efficiency certification. Higher levels, such as Gold or Platinum, waste less power as heat, which can reduce noise and running costs.

What is a semi-passive fan?

The fan stays off at low loads and spins up only when temperatures rise, keeping your PC quieter during light work.

Are ASUS PSUs compatible with other brands' parts?

Yes. Power supplies follow ATX standards, so an ASUS PSU will power motherboards and graphics cards from other brands as long as the connectors and wattage are suitable.
