Topower Tiger 1200W Power Supply Review

Conclusion:

Environmental Factors:

The Topower Tiger 1000W with its high efficiency, good power factor levels and (questionable) 80 Plus status scores very well in this section. No foam packaging and a useful drawer unit mean very little will be thrown away.

 

Price Per the Watt:

Power Supply Topower Tiger 1200W at $200.00 = $0.17/Watt (11-2009)

 

The packaging is very well put together and the drawer unit should be useful for all those important little bits every PC enthusiast has lying about. The use of XLR connectors for the modular cables is also a nice touch which sets the Topower Tiger 1200W apart from other power supplies except the Tagan range from which I suspect, there's a clue on the drawer unit, this power supply is derived. If you need to select between a multi or single 12V rail power supply the option is made available on the Topower Tiger 1200W via a rear mounted slide switch.

A mixed bag in the electrical performance stakes. The DC regulation is exceptional with the 12V rail only dropping 20mV when taken from 0 to over 80 amps! Efficiency and power factor levels are very good but not quite up to the claimed 80 Plus certification following the OCC testing methodology. I will mention at this stage the claimed 80 Plus and Nvidia SLI Ready certification of which I can find no evidence, at the time of writing this review, on the 80 Plus Org or Nvidia websites. The ripple/noise levels on all rails except the +5VSB  were acceptable. Will the high level of 150mV peak to peak on the +5VSB cause any problems? Bare in mind this was measured with the power supply fully loaded at maximum stress and will be significantly lower at say 600W loading and shouldn't cause any high end motherboard any problems.

The Topower Tiger 1200W overall is a good but not great power supply that comes with a great set of accessories at a very attractive price. Don't let the high ripple on the +5VSB put you off too much because I feel it could still do a pretty good job powering any high end gaming or overclocking configuration with multiple graphics cards. The main 3V3, 5V0 and 12V rails are rock solid and the high ripple on the +5VSB will easily be handled by a good quality motherboard.

Pros:

  • Excellent DC voltage load regulation
  • Good efficiency with high PF values
  • Packaging
  • Price

 

Cons:

  • High ripple on +5VSB
  • No evidence of 80 Plus and Nvidia SLI Ready certification
