Corsair TX950W Power Supply Review

Author: Lee Garbutt
Manufacturer: Corsair Components

A Detailed Look

The Corsair TX950W power supply supports the latest ATX12V v2.2 and EPS12V 2.91 standards and is rated for a combined, continuous output power of up to 950 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 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.

The TX950W PSU provides a single +12V output that is rated for up to 78A/936W, which is almost the full capacity of the unit.  This is a trend we are seeing in many new power supplies, which eliminates several potential problems that can occur with multiple +12V outputs.  Delivering a single +12V output is a better approach IMHO.

Specifications (courtesy of Corsair Memory)

The Corsair TX950W power supply enclosure is painted matte black with a yellow logo and is 160mm (6.3”) deep.  It uses a single 140mm fan on the bottom for cooling, which is the largest standard fan size that will fit into the ATX form factor enclosure.  The fan speed is automatically controlled by the internal component temperature (speeds up as the combined load increases).  The dual ball bearing fan (Ong Hua HA1425H12B-Z) is an alternate fan that is used when the regular Yate Loon Electronics D14BH-12 fans are in short supply.  Both fans are relatively powerful and have the potential to provide excellent airflow and cooling.

Note: The clear plastic baffle plate that is attached to the top side of the fan, directs airflow to the front of the power supply where it then flows across the internal components before exiting out the back for optimum cooling.
