Conclusion: Overall, the Coolmax CXI-600B showed decent performance over other highly priced power supplies in this review. Being one of the quietest 600W power supplies we have tested, the CXI-600B will be suitable for users who plan to build a silent system and it can also support up to two PCI-E graphics card thanks to its dual dedicated PCI-E power. The power supply offers a decent number of connectors but it would be better if we had a few more SATA connectors.
Pros: Value buy, Silent, Dual dedicated PCI-E power, Fan speed controller, Lightweight, Excellent +5V and +3.3V rail performance
Cons: +12V rail performance could be better, Only two SATA connectors
