Power, we all think we have enough when it comes to our computers. With the increasing performance and power consumption of todays latest and greatest hardware, the lowly power supply is often an overlooked component. We don't hesitate to spend two or three thousand dollars on hardware, but then we'll skimp on a sixty dollar, 500 watt power supply thinking it will be fine. Then we get upset when the computer doesn't perform to our expectations and we have reboots, BSOD's and other random issues. With 1000 watts of continuous power, the Toughpower 1000 should handle everything I can throw at it. It boasts such features as +/-3% power regulation, up to 87% efficiency, four independent, dedicated 12v rails and a 140mm fan (yes boys and girls that's right, a 140mm fan) to cool down this beast.

Thermaltake, a name we all have come to know as a quality manufacturer of many products for the personnel computer market. These products range from cases to power supplies to heatsinks and even some of the more unique items such as the drive bay cup holder-cigarette lighter combo. Each product has a niche that it is targeted for. Thermaltake was formed in 1999 with it's headquarters in Taiwan and offices located across the globe. Thermaltake is considered to be one of the world leaders in the design and manufacture of thermal management products, computer chassis and power supplies.

Closer Look:

The packaging illustrates the contents of the box and looking at the size of the box I can only imagine how large this PSU is. The box has all of the specifications and features arranged so that you get useful information on all sides of the packaging. A couple things grabbed my attention right away; the 140mm fan and the weight of this power supply. In life being heavy is bad, but in the case of a power supply, it's a good thing.

Opening the box you will find that this power supply comes well protected in a foam enclosure. Not only is it encased in foam, but it's bubble wrapped for further protection. Because this is a modular power supply, the additional cables,silicon vibration dampener and power cable, are packaged in what space is left in the box.

I like what I see so far. Quality packaging and an extensive pack of accessories.

Closer Look:

The items included with the PSU are as follows:

Looking at the bundle of goods shipped, it appears that Thermaltake has thought of everything. Including putting in 8 pin PCIe connectors that many companies will only ship to you after the fact, so you no longer need to worry about whether your power supply will have the right connectors for your new high end graphics solution.The vibration dampener is a nice touch with a product this large.

All of the cables are sleeved on this power supply. This really saves some time and gives a cleaner appearance to the modular cables. This power supply ships with a 20+4 main ATX power connector, 2x 4 pin and an 8 pin connector to take care of your main power connection needs.

One of the features of this power supply is the four independent 12 volt rails. This helps you evenly spread the load among all of the 12volt lines. Even the cabling is labeled to help you identify which rails you should use them on.

Closer Look:

Now we can take a look at the focus of this review, the Thermaltake Toughpower 1000 power supply. Thermaltake calls the covering on this power supply a "High Tech Black coating." The color appears to be close to one I know as argent silver. What do we see but a huge 140mm fan to feed air over the components hidden away inside. The specifications are listed on top so when you are showing off your windowed case mod, that pesky decal does not show. Instead you get the Thermaltake logo and name of the power supply to show off the power in your possession.

The outlet at the rear of the power supply offers an almost unobstructed exit pathway for the exit volume from the 140mm cooling fan. The front of the power supply is all business. This is where we find all of the modular connections. With the four independent 12volt rails, you can see how the balancing of the load can be accomplished. The red sockets are for the video connectors and the black the peripherals. Joe six pack proof it looks like.

Taking a look inside of your power supply is not something you will want to do unless you don't mind voiding your warranty. To keep you from losing that protection should something go wrong, we will take this one apart to show you what is inside this monster. Now I can see where the weight come from. Eight large heatsinks and the 140mm fan to keep the components cool .

Looking to the front of the power supply we can see the circuit board that delivers the current to the modular connectors.

One thing I noticed was the fact that the braided covering heatshrink had stopped before entering the power supply as well as the fact that there was not a grommet of some sort to protect the wiring where it exits the case assembly.


This power supply is a big one. Almost eight  inches long a little over six inches wide and three and a half inches deep. This may prove a challenge for those of you with mid tower cases, but where there's a will there's a way. Fortunately I use one of the larger cases on the market (the CM Stacker) so space was not as big of an issue.

Because this is a modular style power supply, you can slide it right into place. Don't forget to use the included silicon vibration dampener. Once in place, you can button it up so it does't go anywhere.

Once you get it into the chassis, it's a snug fit with very little room left in the power supply housing.

The modular connectors are plugged in one at a time making, your job of routing wiring a much simpler task. The connectors just push in and lock. The latch assembly on each connector makes removing the cable a snap.

Now just make the rest of your connections and you are ready for a cleaner more organized look for your computer.

How do you know if a product performs as advertised? You test it under the conditions it will see on a day to day basis. You also test it under the worst case scenario to see if the product will hold up. Today I will attempt to show both of these extremes. I will perform a no load test to test voltages with the computer in an idle or "no load" state. I will then load the CPU with Stress Prime 2004 Orthos edition, 3DMark06 Professional to load the video cards and HDTach to put a load to the hard drives to try and load all three voltages that we will be measuring. I will be measuring the 3.3volt, 5volt and 12volt lines. To verify the voltages at each level, I will use a voltmeter to check the voltages. Additionally I will use my  Kestral 4100 pocket airflow tracker to find out how much air the 140mm fan actually displaces through the rear exhaust panel.This measurement will be made at both idle and load levels to verify any airflow increase under load.

Testing Setup:

Testing Tools:


Now that I have my baseline numbers I will load test the power supply.


As you can see both power supplies held up well on the load testing phase.


Power. That is what this power supply delivers an abundance of. With the only change in voltage under load being on the 12v1(.04) rail I feel that this power supply has stood up to a pretty stout test. Easily able to power a system with some of the latest power hungry components, this power supply should satisfy your quest for more power. I have to admit, I have owned very few Thermaltake products. With that being said, this power supply has sold me on the quality and performance of Thermaltake's line of power supplies. If you are in the market for a new system, do yourself a favor and don't skimp on your power supply. If you're building a killer rig, be sure to keep the Thermaltake Toughpower 1000watt  power supply in mind when it comes time to purchase. You won't be disappointed.
