PC Power & Cooling Turbo-Cool 860W PSU Review

Author: Lee Garbutt


The Turbo-Cool 860W power supply is rated for a combined, maximum output power of 860 watts (930W peak) at up to 50°C ambient air temperature (internal case air temperature).  Like all previous Turbo-Cool models, the 860W unit features Active Power Factor Correction, universal AC input, and uses a single 80mm fan for cooling.  And as you might expect, the 860 is NVIDIA SLI Certified (Dual 8800 Ultra).

Specifications for the Turbo-Cool 860 (courtesy PC Power & Cooling)

The PC Power & Cooling Turbo-Cool 860W PSU incorporates a single, powerful +12V output that can deliver up to 64A continuous (70A peak).  Going back to a single +12V rail is a trend we are seeing in newer power supplies.  Some manufacturers are no longer creating multiple +12V outputs by implementing current limiting circuits into their design to conform to the 240 VA maximum guidelines – no single output should exceed 240 VA (12V x 20A = 240 VA).  Having multiple current limited +12V outputs can lead to power distribution problems, particularly with some power-hungry video cards.  Delivering a single, powerful +12V output is a better approach IMHO.
