In The Box


Topower PowerBird 1100 PSU


After we get through the shrink wrap and open the box, we find ourselves looking at exactly what we would expect to see. There are not a lot of frills thrown in, but then this is a power supply so frills really aren't necessary.


Besides the main unit, you get all the cabling you will need to run a lot of components, the power cord, a small instruction manual and mounting screws. Topower has also included some small zip ties to help you in your never ending task of cable management.

One of the first things you see when looking at the main unit is the total lack of any cabling coming from the primary housing. Yes folks, this is a completely modular power supply. I have seen many modular designs but this is the first that has gone to the extreme and removed all native cabling from the main enclosure.


The housing itself has a chrome like finish and is pleasing to the eye. The sheen will be a nice accompaniment to nearly any enclosure with a side window. In an effort to be as widely pleasing as possible, the manufacturer has not included any LED lighting. This means that you will not have to consider the light from this when determining your own color scheme.


As for the specifications, the PowerBird 1100 is rated at 1100 watts of continuous draw. It features six 12v rails, each of which is rated individually at 20A. The entire 12v rail is designed to handle a draw of 81A. Both the 3.3v and 5v rails are rated at 28A each. Given the current ATX standard, this ought to bode very well for a PSU of this capacity. While the 12v rail is expected to be potent, a rating of 81A on this one primary rail is very large.

The external panel is pretty much what we have come to expect anymore, a pretty barren area with a lot of openings for ventilation. As is commonplace, the power supply will automatically detect if you are using a 115v or 230v main power input and adjust itself accordingly. You will also note the green light along the bottom edge that lets you know if the unit is getting a proper current. This is a simple addition but a nice one since it takes care of the first step in system troubleshooting.

From this angle you can see the cooling used by the PowerBird 1100, in this case a 120mm fan that has no LED lighting but plenty of airflow with a minimum amount of noise. During all phases of testing I was unable to hear the fan over the noise made from the test system. From this angle you can also see the chrome type finish of the external casing. Just remember to hit the side panels with a soft cloth after you finish the installation so the fingerprints will be removed.

As noted earlier, this model is completely and totally modular. Absolutely nothing is natively connected to the unit itself, so you use only what you need. This even includes the supplemental power adapters for either the Intel or AMD based processors. For those who have not played with a modular design, this makes cable management much easier since you don't have to find hiding spots for all that unused cabling.


I was a bit concerned with having the primary power set up as a modular cable, but I had no difficulties with either installation of reliability when testing the unit. The coupler locks solidly into place and power was always there when it was called for.

Since we are on the topic of cabling, here is what you get with the PowerBird 1100: 20+4 pin primary, 4+4 pin supplemental, 6 Molex, 8 SATA, 2 FDD, 2 PCI-E6, 2 PCI-E8 and 1 combination cable with both a PCI-E6 and a PCI-E8 connector. This gives a huge amount of flexibility and enough native connectivity to utilize even a high-end graphics subsystem like we will be using in our performance tests.


Cable length was set up with a tall mid-tower in mind. Running cabling through an Antec P190 was a breeze, but those running a tall full tower with a separate power compartment under the component area may run into some length issues for those top optical drive bays. Of course, this isn't an uncommon issue, so those with tall cases are usually already prepared to address this.
