ThermalTake ToughPower 850W PSU Review

toughpower-850

Modular AND high quality

There was a time when a bright lightbulb consumed more electricity than a powerful computer.  Those days are long past, as even a modest computer today will eat up an average of 300 watts or more.  The ultra-powerful hardware that tempts the PC enthusiast hungers for more electricity to fuel it, thus creating the need for the high capacity PSUs that deliver 600 watts or more.

Today’s PC or gaming buff will likely have two powerful video cards, a multi-core processor, and other bells and whistles that require alot of amps, and the trend is only getting worse.  Quad-core CPUs are already here, and Quad-GPUs are on the horizon, so they need a beefy power supply with multiple rails to ensure clean and stable power to run it all.

Given the current lineup of power supply products, users are forced to make some compromises.  Right now, units either feature a modular design or have rock-solid performance, but the hardcore modder or gamer wants (nay, NEEDS) both.  Some of the most rock-solid power supplies right now are the OCZ ProXstream 1000W (reviewed here), or PC Power & Cooling, but both of these units are not modular, meaning that your case will be clogged with alot of unused cables.

Thermaltake answers the call with their new and improved Toughpower 850W power supply, which now features a highly modular cable design in addition to re-engineered and highly efficient innards.  Can it be true?  Is there really a power supply that lets us have our cake and eat it, too?
