Previously established as Sirfa Electronics and having over 20 years of experience, High Power was founded in 2008 and their headquarters are located in China. They mainly specialise in making power supply units. Today we are testing the High Power Performance Pro 550W PSU, which has an 80Plus Bronze certification and is non-modular.
Let’s take a quick look at High Power Performance Pro 550W, taken directly from the company’s website:
The High Power Performance Pro 550W comes in a brown and black glossy box, whose front side has a picture of the unit and the back side contains a connector listing and a feature overview.
At the sides of the box there is an illustration of the PSU, as well as a table with the features listed.
When the cover is opened, a luxurious cardbox can be found. However, there is no foam material to protect the unit during shipping.

The package includes 4 screws for mounting the PSU inside the case, as well as a High Power logo sticker. Furthermore, we can find a User Manual and three high quality cable straps.Of course, a power cord is also included for connecting the PSU to the wall outlet.We can see also two 3-

The unit comes in a neat black finish and is well crafted with a nice build quality. The back side is filled with holes to help air ventilation, and there we can also find an ON/OFF switch. At the bottom side there is a DC output table, while at the cable connectors side there two additional connectors dedicated for 8cm, 9cm, 12cm, or 14cm fans, with AI Temperature control feature that can manage fan speed accordingly to keep temperature and noise levels at optimal balance. The PSU follows a non-

Efficiency and Noise Test
We have been using the High Power Performance Pro 550W for about 2 weeks now, and it has been put to stress a lot during this time, powering an overclocked Intel i7 920, accompanied with a powerful GTX 460. Never once did we experience any issues with this unit.
As we can see from the test results, the PSU managed to achieve a combination of all characteristics that a good PSU should have: strong, efficient and quiet for the category.
It does not focus on design, as it does not have lighting or fancy colours, maintaining a simple aesthetic design. It is exceptionally stable, extremely quiet and particularly reliable. Combined with the quiet-running fan, the unit’s noise levels proved to be logical for the performance.
The High Power Performance Pro 550W will also reduce your electricity bill by being more efficient than most other power supply units which is an added bonus.Not many power supply units out in the market in this category are as efficient as the High Power 550W. Most middle to low range units will not even handle their rated load and will get loud while trying to reach it. The price of approximately 80 EUR places the Performance Pro 550W in the position of a solid competitor in the PSU market, given its build quality and performance.
Of course, we would prefer it to be of modular design, but maybe this is too much to ask for in this price range.
(+) Exceptionally efficient
(+) Silent operation
(+) Extremely strong regulation
(+) Nice price
(-) Not modular
Thus we believe that giving the High Power Performance Pro 550W unit our Value For Money Award would be the best way to end this review, as it offers good performance in a very reasonable price.
