Lowest Prices

Conclusions:

 

Price Per the Watt:

Power Supply Corsair TX750 V2 750W at $104.99 = $0.14/Watt (05-2011)

Power Supply Corsair TX850 V2 850W at $124.99 = $0.15/Watt (05-2011)

 

So what's changed?

The second revision of the ever popular Corsair TX750 and TX850 power supply now offer 80 Plus Bronze efficiency as opposed to the standard 80 Plus certification of the original units. This in combination with far better noise/ripple on the DC rails and some improvements in the overall build quality, sleeved cables all the way into the power supply for example, do make for a better quality power supply. The Corsair TX750 V2 and TX850 V2 performed very well overall and to a very similar standard with the only difference of note being the slightly higher +12V ripple/noise levels on the 850W which is understandable given the higher rail loading. The efficiency levels although not quite hitting the required levels required by the 80 Plus Bronze certification following the OCC power supply testing methodology were still a respectable 85~86% at maximum with power factor levels causing no problems as usual.

The Corsair TX750 V2 750W and TX850 V2 850W are still very good power supplies but they now face stiff competition from the likes of the XFX Core Edition power supplies and I can't help but feel that Corsair haven't quite done enough second time around. They are priced slightly cheaper than the originally released units which is nice to see but 80 Plus Silver efficiency would have introduced a little space between them and some of the competition. The DC quality was good but the ripple/noise levels on the DC rails are still a little higher than other power supplies in this class and there is room for improvement.

The Corsair TX750 V2 750W and TX850 V2 850W are still very good power supplies and I'm sure they will still remain popular in the PC enthusiast community but I feel the performance could of been improved further second time around. The Corsiar V2 units did perform very well and are an improvement on their predecessors so they still come highly recommended and I have no hesitation in awarding them the OCC Silver award.

 

Pros:

  • Great DC voltage load regulation
  • 80 Plus Bronze certification
  • 5 year warranty
  • Good user manual
  • Plenty of connectors

 

Cons:

  • Noisy fan at full load
