Tagan 2 Force II 900W Cross Fire certified Power Supply Unit

Voltage Ratings

As you can see from the picture above the TAGAN TG900-U33 has a max output current of 26A on the +3.3v and +5v rails, and 20A on the six +12v rails giving them a total maximum output current of 70A. The maximum combined power for the +3.3v and +5v is 170W and 840W for the +12V rails. The -12v and +5Vsb have a max output of 0.8A and 3.0A respectively and a combined power output of 20W. (9.6W, 15W)
Testin:

To test the system we hooked up the TG900-U33 onto one of our gaming systems. Here are the specs:

Our testing procedure consisted of first getting voltage readings at system idle and then while on full load using a multimeter. Getting readings off software that often come with motherboards will not give you accurate results, so if you plan to test your PSU you’ll need to use a multimeter.

A thing to note is that most high powered power supplies become more efficient as more power is drained off them. Of course you’ll never really reach the full power output this PSU provides in real life unless you put it on some electronic load simulator; nevertheless we believe the above rig should be adequate to produce a real life scenario which everyone can relate to.

Max load was obtained by overclocking the system slightly and using benchmark tools such as 3D mark, PRIME and a few games for a couple of hours. So here are the results.

The Wattage used on idle was 305W and on Full load 563W. Ambient Temperature at the time was around 22C and the PSU temperature on idle was 26C and on Full load was 31.6C.

As the results show the TAGAN TG900-U33 900W Power supply performs extremely well and within specifications of +/- 3%. On full load the system is still very stable and we didn’t have any problems at all. These results were taken after an hour of continuous stress testing.
Conclusion:

Having used this power supply for over a week now I must admit it certainly is a great performer. It certainly got what it takes to be a kick-ass power supply for the hardcore user. TAGAN power supplies have received profound respect and end user acceptance due to its industrial strength performance.

The only real drawback of this PSU is Nanopoint didn’t adopt a modular design which would have been good, other than that, I simply cannot find any fault with this unit. It’s got a lot of expansion options and enough power to handle even the highest rated quad core CPU setup. We got word from Nanopoint they’re coming out with a new modular design with the same features as the U33; it’s the U88 which will be coming out in July. So keep an eye out for that if you really want to go with such a setup.

In addition it comes with Active PFC, over voltage and over current protection and an efficiency rating of 80%, making the TAGAN TG900-U33 one of the best mainstream power supplies in the market right now.

If you’re in Australia head down to Actiontec as they’re the main distributor for these units. Everyone else visit Nanopoint and check out where you could purchase one of these units. We’re very confident of this product and it receives our “recommended” award.

Pros:

* Active PFC
* Silent operation
* Fully sleeved cables
* OCP and OVP protection
* Excellent performance
* High efficiency rating

Cons:

* No modular setup
