Describing any review involving PC Power & Cooling products is more difficult then one might think. How do you describe a company to which so many accolades have already been attributed? Today we have the honor of testing the Turbo-Cool 1000W (1kW) PSU

How was the subjective noise level?

Yeah I've heard P&PC PSUs can get noisy, would you consider it so?

How is this PSU compared to:

- Enermax Galaxy EGA 1000EWL
- Tagan TurboJet TG1100-U95

Sorrt about the late reply. Currently I'm runing a kandalf case ruinning three 120mm fans and a single 90mm fan and I cannot hear the Turbocool under full LOAD.

Insofar as the Enermax 1000W the design is intersting, it's based on Dual Tranformers "the first transformer drives the +5 V output and the +12 V output used on the cables that are connected on the motherboard (labeled “CPU”), while the second transformer drives the +3.3 output and the +12 V output used by peripherals."

"Enermax uses a “virtual rail” concept, where they label their power supplies as having separated +12 V rails but inside the unit they are all connected..."

For Tagan, in their Turbojet 1100, which is effectively a Topower 1100P9 as is evident here here ), they've taken marketing-fodder to the point it's an insult to our intelligence. If I wanted a faux leather suitecase I could buy it at a Tag Sale, however, that's not the worst of it. If you estimate cost ratio, almost 20% of total cost wen't toward a superfluous piece of luggage. That could have bought another transformer, better capacitors, external; pots with meters even watercooling options.

PCPower is the only manufacturer to split their rails into individual power modules and on the TC1KW which reviewed it's as follows 3.3V and 5V on the first module running the length of the unit 12V3 cenetr module handles all periperials and two PCIe, and the left hand module is responsible for 12V1, 12V2 CPU.

66A total for the 12V rails definately low for this unit, but that's because they've basically stopped making this model and are almost ready with a replacement for the maximum power TurboCool to be reviewed here. The next revision will have some surprises and once again we'll see why PCPower has and contrinues to be one of the leaders and perhaps the most innovative PSU maker out there.

Now don't think I'm some "fanboy" but as continue to study PSU design I'm beginning to realize even with their high costs PCPower may make the least amount per unit then any other maker.

that's some good info there L3D, thanks

I read in a SPCR review that PSUs with only 1 real 12V rail are better than the ones with split rails since split rails only exist because of some stupid regulation.

Intel specs for P4 LGA775 requirement in fact

Exactly as JMKE stated, and the "12VDC Guidelines" were introduced solely for the benefit of Intel whom required the extra voltage for their then, NetBurst power hungry processors, hence the 2x4 baseboard connector anbd split-rail design.

PCPower has been the ONLY company to outwardly denounce these Guidelines and design around them as is evident way back in the TurboCool 510 which exceeded the 20A current limitation on the 12V rail at 34A (38A Peak) as seen in their SLI specs here http://www.pcpowercooling.com/produc...hp?show=T51SLI
and their ATX version specs here
