The Corsair AX1500i Digital power supply supports the latest ATX12V v2.4 and EPS12V 2.92 standards and is backward compatible with ATX12V 2.2 and ATX12V 2.01. The AX1500i is rated for a combined, continuous output power of up to 1,500 watts at 50°C operating temperature. That’s important as some less reputable manufactures limit their power supply’s advertised capacity by specifying a lower operating temperature (25°C) in the fine print.
The AX1500i Digital PSU incorporates a single +12V output (user-configurable virtual “single” or “multi-rail” software modes) that can deliver up to 125A, which is the full capacity of the unit. The PSU includes universal AC line input (automatically adjusts the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid.
Note: The AC input range is listed as 100–240VAC but there is also a limitation in the Maximum Combined Wattage section: the AX1500i can only produce its maximum combined wattage of 1,500W when supplied with 115 VAC mains or higher. If you have less than 115 VAC, then the PSU has to be de-rated to 1,300 watts so that it will not exceed 15A AC. During our testing, when the AX1500i was fully loaded (1,500 watts) and operating on 115.4 VAC, the unit was drawing 14.42A. So remember, to maintain constant power, as voltage decreases, current flow increases; going below 115 VAC will quickly push the AC amps over the 15A rating.
