INTRODUCTION

Over the last two years the power supply for the computer enthusiast’s most prized possession has moved from a level of virtual obscurity to an element of key importance. No longer will a reasonably inexpensive 400 Watt power supply that produces relatively clean power satisfy the insatiable appetite of all your system’s components. This is due in no small part to the major changes in architecture that both the current day CPU and GPU have undergone.

The vast majority of enthusiasts are running at minimum a single dual core processor and quite a few are utilizing quad core variants. This processing power is complemented by anywhere from one to as many as four GPUs each requiring higher levels of power to function at optimal capacity. For good measure toss in up to half a dozen SATA or SCSI drives running in one or more RAID arrays, a couple of other PCI or PCI-e cards, four to eight 120mm fans for optimal cooling, miscellaneous USB devices, and a few other unmentioned goodies. Mix all these components together and you’ve got one power hungry monster on your hands.

Let’s Talk Auto Combine

If you keep up with the latest information about power supplies you’re certainly aware of the ongoing discussions that have been taking place recently concerning the benefits and limitations of power supplies designed with multiple 12V rails as opposed to those with a single 12V rail. Some enthusiasts have reported situations where the ability of the one or more of the multiple 12V rails was compromised and could not meet the power needs of the attached components. In some cases these individuals had to procure a power supply with a single 12V rail and higher power output to meet their needs. Other equally extreme users have never experienced the aforementioned scenario using a multiple 12V railed power supply.

Tagan took these issues to heart and has attempted with the ITZ 1300 to give the computer enthusiast the best of both worlds by implementing what is called Auto Combine. Auto combine recruits the power of all six 12V rails into a single rail for uninterrupted stability with up to 1104 Watts and 92 Amps of power. On the ITZ 1300 this features is seamless, once the 12V1 power demand exceeds 28A the Auto Combine feature is automatically implemented. On other models in the ITZ series there is a manually operated Turbo mode button on the rear of the power supply adjacent to the power switch that implements the auto combine feature manually.

To better understand why the Tagan ITZ 1300 rates each of its 12V rails at a maximum current rating of 20A as opposed to 28A, we asked Tagan. It seems that in Germany if a PSU exceeds 20A per rail, a certified engineer is required to install the PSU. We can only imagine the indignation of having to call an engineer every time we wanted to switch our PSU from one case to another, so this makes perfect sense.

Other Features We Questioned

Having an extremely inquisitive nature we had two more questions for Tagan concerning the features included on this PSU.

Question 1:   Why two 80mm Fans instead of a single 120mm or 140mm? Answer:   Two 80mm fans arranged in push/pull fashion gives the maximum cooling without a substantial increase in noise.

Question 2:   Please tell us more about the design of your PCI-Express cables, as they are the first we have seen with EMI shields of the type used? Answer:   The PCI-Express cables are copper shielded with EMI shield to reduce noise level, radiation from video. The patented EMI shield has over voltage, over current, and short circuit protection. To prevent the VGA from being fried in case lightning or short circuit.

Packaging

The Tagan TG1300-U33 ITZ 1300 Watt power supply arrived at our doorstep in excellent condition due primarily to the excellent packaging that Tagan affords this product. The image below depicts the outer package which was shipped in a very solid cardboard box with plenty of packing material to dampen any mishaps along the way.

Inside the outer package are two much thicker cardboard containers. One contains the power supply and is depicted below and the second holds all the included accessories.

External View

Normally as most of you know we don’t dwell on aesthetics in our reviews of power supplies as they are usually somewhat removed from the focus of your system. We generally spend the vast majority of our words catering to the positives and negatives of the device’s performance. We were so taken back by the titanium blue that Tagan used with the TG1300-U33 ITZ and its lustrous mirror finish that we decided to make this review an exception to the rule.

To do justice to the photographs of this product we had take it outside in the sunlight as otherwise the colors in our indoor studio were dull and bordering on black even using external lighting and several different lenses on our Nikon D40. Below are a number of different images of what we feel is currently the best looking power supply on the market. Performance will be examine in detail later in the review.

We alluded to the mirror image of the product’s finish. I think you’ll see what we mean! In most images above you’ll notice there are very where we didn’t capture a small reflected image on the power supply’s surface.

Another extremely impressive feature of the physical build of the Tagan TG1300-U33 ITZ is its size and dimensions. Most of the new “super power supplies” (those 850 Watts and greater) have opted to use much larger cases for their designs. Some of these variant cases extend to over 9 inches in length making it very difficult to mount them in the average mid-tower and even some full-tower cases. Tagan has designed this product so that it’s only slightly larger than the “normal sized” power supplies that we all cut our teeth on. The dimensions are 5.875″(W) x 3.875″(H) x 6.875″(D).

CLOSER LOOK

Internal View

Inside the case we see a component view of the Tagan TG1300-U33 ITZ 1300 Watt power supply. There are two round large aluminum heat sinks each horizontally configured for optimal heat dissipation. Tagan describes all of their internal components as “industrial grade”.

We were especially interested to see what type of 80mm fans Tagan used to cool this behemoth with. As the image below illustrates that fans carry the Tagan label but are most likely OEM from some other manufacturer. The reason for our extreme curiosity will become evident later in the review in the testing phase where we look at the noise levels output of this power supply. If you look closely you can see that Tagan also uses rubber washers with each of the 80mm fans to minimize vibration.

Included Components

The Tagan ITZ 1300 includes the basic complement of supplies you would expect to find with any power supply plus a few extras.

  • 1 – Tagan ITZ 1300 Watt power supply
  • 1 – Users Manual
  • 5 – Velcro cable bands
  • 2 – Wire ties
  • 1 – Rubber anti-vibration mask
  • 5 – Chasis Screws
  • 4 – SATA to Molex connectors

Tagan TG1300-U33 ITZ … Included Accessories

 

Tagan takes a distinctly different approach with the available connectors on this product. Most manufacturers of power supplies in this class give you more 12V Molex connectors than you will ever need and just enough SATA power connectors to meet the most basic requirements. Tagan includes a whopping twelve SATA power connectors and seven 12V Molex connectors. Also included are four SATA to Molex adapters pictured in the image below which allow you power up to 19 drives or other 12V devices. Also pictured is the Y-cable with two floppy drive power connectors just in case you still have the need for one of these ancient products.

SATA to Molex Adapters & Floppy Power Cable(s)

 

Cabling:

All cable is fully sleeved with high quality mesh sleeves except for the PCI-E cables which are sleeved with thick solid vinyl sleeves.

  • 1 – 500mm 24 pin main power connector
  • 1 – 550mm +12V 8 pin EPS cable
  • 1 – 550mm +12V 4 pin cable
  • 2 – 550mm 6 pin PCI Express cables
  • 2 – 550mm 6+2 pin PCI Express cables
  • 1 – 550mm cable with two 6 pin Physic Card power adapters
  • 3 – 550mm cables each with 4 SATA power adapters
  • 2 – 500mm cables each with three 4 pin Molex power adapters
  • 1 – 500mm ground wire
  • 1 – 250mm cable with a single 4 pin Molex power adapter … this cable is to be combined with the included 150mm FDD Y-cable for powering up to two Floppy drives

As modular cabling connectors have vastly improved in the last year, I have developed a personal preference for power supplies with a modular design, as it greatly aids in cable management. The proper modular design prevents the user from having to bundle unnecessary cabling within the case making for a much cleaner and easier install. As stated this is a “personal preference” and due to some of the “power supply gurus” making a case that some modular designs can be a detriment resulting in power leakage and efficiency loss.

The Mass of Power Connectors on the ITZ 1300

 

As the next image shows all of the PCI-e power cable are sleeved in a high-grade vinyl. The Tagan TG1300-U33 ITZ comes with two sets of PCI-e cables labeled “A” and “B”. In each set there is a standard 6 pin PCI-e cable and the newer 6+2 pin cable that can facilitate the needs of the newer AMD Radeon graphics solutions.

 

Tagan also includes a single ground wire that when connected to the case will help dissipate static electricity preventing the loss of a component from a high level static electrical discharge.

Test Methodology

Let’s face it, with a power supply this is the real meat of any review. Power supply pictures and verbose descriptions mean absolutely nothing without the ability to produce the desired results. We decided to compare our test results for the Tagan ITZ 1300 Watt power supply against the PC Power & Cooling 1KWSR 1000 Watt power supply. We are planning to really try and drive the Tagan ITZ 1300 to the limits our test rig will provide, for that reason none of our previous test results will be used.

To act as a break-in period for the Tagan ITZ 1300 Watt power supply I ran it for several days in the above described test system case and allowed it to run virtually undisturbed during normal everyday use ranging from surfing the Net to some hard-core gaming. To establish load conditions we ran a variety of different processes on our test system to create as much power demand on the Tagan ITZ 1300 as the components of the test system will allow.

Because of the complexity of changing out a power supply 6 different times we decided to test the components using a recently acquired large HSPC Tech station. While this test environment doesn’t completely simulate the results in a case we feel that using it uniformly with all test components should make the results relative. All electrical measurements were measured using a Velleman digital multimeter and a Seasonic Power Angel. Sound/noise measurements will be acquired using a new Omega HHSL-1 digital SPL meter.

As most of you are aware it is virtually impossible to drive a 1300 Watt PSU to its maximum load capabilities using even the most sophisticated test rig even with the number of components we have added to increase power draw. Unfortunately, at present Bjorn3D doesn’t presently own an electronic load simulator to drive these devices to their maximum output. Hopefully we’ll have one of these devices in the not to distant future. While measurements taken using one of these devices show the true and ultimate capabilities of the power supply being tested, it’s not “real world”. By this I simply mean other than for bragging rights, why measure something you’ll probably never practically attain. The question then arises why buy a power supply that provides more than you need? Most computer enthusiasts subscribe to the premise that a power supply should never be driven in a real life environment to more than 75% – 80% of it’s capable output for obvious system performance reasons. I personally feel the 60% – 70% range gives you more of a performance comfort zone not to mention keeping your system nice and cool which also translates into quiet.

With our system tuned and ready to go we did initial power consumption measurements at both idle and full system load. With every component tweaked to draw the maximum power possible we were able to achieve power consumption levels of 350 Watts (± 5%) at idle and 500 Watts (± 5%) at load. The demand would have been higher if we had been able to run our SLI configuration with two XFX 8800GTX XXX graphics cards. Since we only have one and had to substitute a Foxconn 8800GTX that was clocked at normal speed as the second card in our SLI configuration. As you are probably well aware when running SLI with cards of two different speeds the system will default to the clock speed of the lowest clocked card.

CONCLUSION

We suggested in the introduction to this review that we would determine whether the Tagan TG1300-U33 ITZ 1300 Watt power supply brings the goods to the table. I think the results of the testing unequivocally speak for themselves. This is one of if not the best power supplies in its class that we have tested to date at Bjorn3D. The power output of the Tagan is not that surprising considering we only stress it to about 40% of its full load potential with our test rig. What is surprising is minute variances we observe between idle and load, in all cases we saw no more than 2% on all rails.

We were also extremely impressed with noise levels or should we say lack of noise levels that this power supply produces. During the entire course of our testing, we never heard an audible difference in the fans; this was confirmed by our sound pressure meter showing no change in level between idle and load. Out of all the highly impressive features this unit brings to the market, we were most impressed with the Auto Combine feature. This element automatically balances the load and will convert the unit from six 12V rails to one monster 12V rail should the need arise.

The average consumer might balk at the current $400 USD price tag, but then again our reviews are not slanted toward the needs of the average consumer. The computer enthusiast on the other hand would probably find this price to be a bargain given the power level and feature set the ITZ 1300 provides. If this power supply had modular cabling it would have been probably that it would have received an even higher score. Fear not ye of modular mentality, Tagan has informed me that in late September we can expect to see this power supply as well as others available in a modular configuration.

Tagan pulled out all of the stops with its ITZ series of power supplies. This is further affirmed by the certification for use of the TG1300-U33 ITZ in the most extreme gaming ayatem by ABS Labs. We at Bjorn3D highly recommend this power supply to anyone looking for an extremely powerful power supply that looks great and is so quiet it’s barely audible.

 

Pros:

+  1300 watts of clean, solid, and stable power
+  Six independent & dedicated +12V rails
+  Active PFC
+  High efficiency rating > 80%
+  Quad SLI/GPU ready
+  Compact case dimensions
+  Dual Core/Quad Core CPU ready
+  Next Generation 8-pin PCI-E connectors
+  All cables fully sleeved
+  Extremely quiet operation

 

Cons:

-  A modular design would make cable management easier
-  The price may be too steep for the average consumer

 

Final Score: 9.5 out of 10 and the Bjorn3D Golden Bear award.
