These days there are a lot of people that try and look for efficiency in their everyday life. At the same time there is also a multitude of people that try to conserve energy. With these two concerns prevalent in the world why not try and do your part by tuning up you computer to make it run at peak efficiency. With the Thermaltake Litepower 450W Power Supply, you can add a finely tuned piece of equipment to add efficiency to your PC’s power consumption. For many out there this power supply will be more than enough to cover your power consumption needs. Let’s take a closer look at this efficient piece of equipment:
Product Provided by: ThermaltakePrice: $89.99
Closer Look:
The packaging for the Thermaltake Litepower 450W Power Supply is a little different, yet plain from some of the items we have received in the past. The images on the front, top, and rear of the box resemble the PSU itself. The bottom of the box has a few features and lists off the total output connectors, also tells you to view the Thermaltake webpage to see more product details.
There really isn’t much included with the Thermaltake Litepower 450W Power Supply, all there is inside the box is an instruction manual, the power cable to plug it in, a couple of Velcro straps for keeping the cables in line, and four screws to mount the PSU in your case.
The attached cables for the Thermaletake Litepower 450W Power Supply are; one 20+4pin Main Connector, one 4pin +12V CPU, one 6pin PCI-E Connector, four SATA Connectors, five Peripheral Connectors, and one Floppy Connector. The fan mounted in the top is a silent 12cm fan and inside it houses dual +12V rails.
Now let’s move on to the specs and features:

Now let’s move on to the testing:
Testing Setup:
- CPU: Q6600
- Motherboard: Gigabyte GA-965P-DS3
- Memory: 2 x 2GB Kingston
- Video Card: ATI Radeon EAH 4550
- Power Supply: Thermaltake Litepower 450W
- Hard Drive: Seagate 500GB SATA
- Optical Drive: LG DVD-RW With Lightscribe
- OS: Windows XP Home SP3
Testing:
For testing I will be doing a few standard tests. First I will connect a LCD power supply tester before I connect it to my PC. Next I will record the voltages while it runs idle and then under load, which will be achieved by running the Prime 95 burn-in test. The idle and load numbers will be regulated by the on board motherboard sensors. I will be putting the Thermaltake Litepower 450W Power Supply against my Seasonic 550W Power Supply.
LCD Test:
| Test | Thermaltake 450W | Seasonic 550W |
| +5 | 5 | 4.9 |
| +12 | 12.1 | 12.1 |
| +3.3 | ERROR | 3.2 |
| -12 | 12.3 | 12 |
| 5VSB | 5 | 4.9 |
| PG in ms | 270ms | 310ms |
Idle Speed Fan Test:
| Testing | Thermaltake 450W | Seasonic 550W |
| +3.3v | 3.36 | 3.25 |
| +5v | 5.11 | 5.16 |
| +12v | 12.19 | 11.86 |
Load Speed Fan Test:
| Testing | Thermaltake 450W | Seasonic 550W |
| +3.3v | 3.36 | 3.25 |
| +5v | 5.11 | 5.16 |
| +12v | 12.19 | 11.79 |
So from these numbers we can see that sometimes efficiency is all it takes to make a good PSU. With the Thermaltake Litepower 450W Power Supply I actually received better output because of said efficiency. For some unknown reason we received an error code during the LCD test for the +3.3, but once connected to my PC everything appeared to run just fine so we are unsure of what to say about that. While under load the voltages for the Thermaltake Litepower 450W Power Supply didn’t even flinch which I was shocked to see.
Let’s move on to my final thoughts:
Conclusion:
To be truthfully I am totally happy with this power supply. Other than the odd error code during the test the Thermaltake Litepower 450W Power Supply functions just fine and I haven’t had any problems with it. With its high efficacy and low power consumption this power supply is a great option for streamlining your PC.So in the end would I recommend this product? Yes, yes I would. For many people this power supply is more than enough. From home theater PCs to light gamer computers, this would be a great option. For those that have huge monster gaming PCs and need massive power supply's then this might not be for you. However those that are looking for a new power supply, whether its for a new build or simply a replacement I would strongly recommend the Thermaltake Litepower 450W Power Supply if it fits the size of PSU that you are looking for.
Pros:
- High Efficiency
- Low Power Consumption
- No Power Fluctuations (During Our Tests)
- Reasonably Priced
Cons:
*These Cons Are for Some People’s Personal Preferences, Not Cons Against The Power Supply Itself*
- Not Modular
- No LEDs
