What Certified Refurbished Means
If you want high-performance power for your build without paying full price, a CORSAIR certified refurbished PSU is a practical choice. Each refurbished power supply goes through a rigorous testing and inspection process, is cleaned, and is repacked to meet the same performance standards as a new unit — giving you access to CORSAIR's proven PSU lineup at a reduced price, backed by a warranty for added confidence.
CORSAIR's certified refurbished program is not the same as buying a used PSU from a third-party seller. Every unit is tested by CORSAIR to confirm it meets original performance specifications, then cleaned and repacked before it reaches you. This process removes the uncertainty that typically comes with a used power supply purchased through an unverified source.
ATX and SFX Form Factors
This category includes both full-size ATX and compact SFX power supplies, so whether you're building a standard mid-tower or a small form factor system, you'll find options that fit your case:
- ATX PSUs: Suited to standard and full-tower cases, offering a wide range of wattage options for mainstream and high-performance builds.
- SFX PSUs: Built for compact ITX and mini-ITX cases where space is at a premium, without sacrificing output quality.
If you're searching for a used SFX power supply for a small form factor build, this is the right place to look.
Choosing the Right Wattage
Wattage is the starting point for any PSU decision. As a general guide, pair your PSU wattage to your CPU and GPU power draw with some headroom for other components. Higher-end graphics cards and multi-component builds will need more headroom than entry-level systems. Check the TDP of your CPU and GPU before selecting.
Efficiency Ratings and Features
CORSAIR refurbished PSUs carry 80 PLUS or Cybenetics efficiency ratings including Gold and Platinum tiers, which means less energy is wasted as heat during operation. A range of features are available across select models, including:
- Fully Modular Cabling: Attach only the cables you need for a cleaner, easier build.
- Zero RPM Mode: The fan stays off under low loads for near-silent operation.
- ATX 3.0 Compatibility: Ready for the latest GPU power connector standards.
