We've had some feedback from the supplier who supplied PC Review's Tagan TG480-U22 Power supply for our recent article (see latest articles, left).
If you've read the review, you'll have noticed I mentioned the switch allowing you to choose between a split 12V rail and a common one.
The good folks at Nanopoint who supplied the TG480-U22 for review have been in touch and pointed out the benefits of this function.

I'll post Nanapoint's reply and the official blurb on this model below as I think it's important the Tagan's future proof capability is mentioned here.
Here is Nanopoint's reply to PCReview, followed by Tagan's official output on this new model.
To my mind it makes the new Tagan TG480-U22 more attractive than I originally realised.
From Nanopoint:
In terms of the difference between the TG480-U01 and TG480-U22 is that the TG480-U22 has a dual 12v rail, conforming to the ATX 12v 2.01 spec.
The switch at the back that allows you combine & split the 12v rail just allows compatability between ATX12v 1.3 & 2.01 respectively. The TG480-U22 has now two independent PCI express as oppose to one that you had in the review. So the difference between TG480-U01 & TG480-U22 (Tagan Two Force series as it is known) is that the latest version is future proof, since Intel may or may not replace the existing standard 1.3, so buy a TG480-U22 and you will not need to change your PSU when the new standard is introduced.
And more info on the PSU:
TAGAN INTRODUCE “TWO FORCE” SERIES- THE WORLD’S FIRST PSU COMPATABLE WITH BOTH INTEL’S ATX12V 1.3 & THE LATEST STANDARD ATX12V 2.01
Tuesday, 22nd February, 2005- Tagan is delighted to announce its “Two Force” series, named after its dual 12V rail. This is to accommodate the increase in the +12 VDC currents as system components that withdraw its power from the 12V rail are expected to demand more power than ever before. The latest development from Tagan complies with the new Intel ATX12V 2.01 power supply standard, which states in cases where expected current requirements is greater than 18A a second 12 V rail should be made available. The new specification also require a minimum measured efficiency to be 70% at full and typical (~50%) load and 60% at light (~20%) load.
So what will be the main benefits of the new Intel ATX12V 2.01 standard over the existing ATX12V 1.3? The new standard will allows PSUs to increase its power output enhancing its capability to run the ever power consuming components such as CPUs and graphics cards. It will also offer greater stability. The other benefit is the increase in the PSU’s efficiency, which means less power is lost as heat through the power supply and hence cheaper electricity for end users.
Tagan’s Two Force Series is believed to be the first PSU in the world to be compatible with both ATX12V 1.3 and ATX12V 2.01 standards. A switch at the back of the PSU allows users to alter between combining the 12V rail (ATX12V 1.3) or to separate the 12V rail (ATX12V 2.01). The Two Force Series will also be fully SLI ready, fully equipped with two independent SLI cables to power the latest graphics card in the market available today. Tagan’s latest offering has once again followed its philosophy of always being the first and being the best having previously been the first to introduce transformable mainboard connectors and the first to implement PCI Express in a PSU. The Tagan Two Force series will be showcased at CeBit, 10-16th March 2005 in Hall 19, Booth C05.
