80 PLUS Platinum Certification
Excess heat means wasted energy. 80 PLUS Platinum certified efficiency means less heat generation, less energy waste, and lower operating costs.

Clean, Stable Power Delivery
High-quality capacitors, a dedicated single +12V rail and a PF value of 0.99 give you reliable power output with extremely low ripple and noise. Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components. And, AX860 is engineered to meet maximum power output at a server-grade 50° C temperature rating.

Zero RPM Mode for Silent Operation at Low Loads
The fan doesn’t even spin when your system is idle or doing basic work like surfing the web or running office applications.

Fully Modular Connection System with Low-profile Cables
All of the power cables have connectors on both ends, with nothing hard-wired to the PSU. This makes for easier installs (you don’t need to deal with an octopus of cables while you’re putting in the power supply), and you can add cables one-by-one, using only the cables you need. The result is a cleaner-looking build, with better airflow.
Flexible and Compatible Design
AX Series comes with long cables for large cases, and lots of connectors for just about any hardware configuration.

Wide Compatibility
The AX Series conforms to ATX12V v2.31 and EPS 2.92 standards, and is backward compatible with the ATX12V 2.2 and ATX12V 2.01 standards. It accepts universal AC input from 90V - 264V. Safety approvals include cTUVus, CE, CB, FCC Class B, TÜV, CCC, and C-tick.

Pros: -Fully modular. -Completely silent! -Platinum!
Cons: -Multiple "double" wires on the 24-pin connect make sleeving difficult! Not a true con, just a warning to anyone planning on sleeving this PSU! Also, wires cross preventing you from sleeving an even pattern.
Overall Review: I managed to fully sleeve the PSU, despite the double wires and uneven routing. It looks great and can't be heard! Awesome!
