What to look for in an ATX power supply unit
An ATX power supply serves a simple purpose, but there are plenty of things you’ll want to look at when considering a purchase.
- Size and case compatibility: ATX power supplies are larger than SFX units, so be sure you’re matching your power supply to the space and case you’ve got.
- Continuous power: Measured in watts, the power handling of your unit needs to be matched to the power needs of your components.
- Efficiency ratings: We’ve compiled ratings from 80 Plus and Cybenetics.
- Connectors: Double check that your PCIE or EPS connector needs are met.
- Modularity: Modular PSUs can help with cable management and clear up space.
What is an ATX power supply unit?
Developed in the mid-90s, ATX is a power supply and motherboard configuration standard that stands for “Advanced Technology Extended”. This technology has a strong track record in computing, and CORSAIR is carrying the torch forward with lab-tested, efficiency-certified ATX units that can run your full PC operation. While ATX units are reliable and efficient, they aren’t quite as compact as SFX units, so be sure to check on your case size and what space constraints you may have for your PC build before selecting an ATX PSU.
