Top 450 Watt Computer’s Power Supply Unit

Report Data Collected On: 1/Nov/2018

We can have a computer with the fastest and most powerful components of the market, with large amounts of RAM, many-core processors and the most complete of the motherboards, however, all this depends on a small device called “Power Supply”, without the which none of these components could work.

Ignored by most users, the power supply of a PC is responsible for supplying the energy that all the components and peripherals need to do their job, and it is an incredibly complex and precise piece, since, in addition to supplying the energy necessary, it does it in a perfect and constant way.

Bearing this in mind, it could be said that the power supply is the most important component of a PC, and we should pay attention to it as to any other device inside the cabinet, and even more, since if it does not offer a certain range of parameters, those appropriate to our hardware, may not do their job properly.

Basically, a power supply works by taking the 220V of the electrical network and reducing them to 3.3V, 5V, and 12V, which are the necessary values so that all the internal components of the PC receive the correct supply voltage for its proper functioning. For this, it uses transformers, coils and other electronic components such as capacitors, resistors, diodes, integrated circuits and others.

  • Maximum Power Output: 450W
  • Fan Size: 1 x 120mm thermally controlled rifle bearing fan
  • Energy Efficient: 80 PLUS Bronze
  • MTBF: >100,000 Hours
  • Dimension: 3.39″ x 5.91″ x 5.51″
  • Type: Semi-Modular
  • Connectors: 1 x 24-pin ATX,
    1 x EPS Connector, 1 x Floppy Connector, 1 x PCIe Connector, 4 x SATA Connector, 4 x 4-Pin Peripheral Connector

Short ReviewCorsair has been the reference in the field of RAM for many years and offers all finest products. They provide extremely high-quality and very popular with overlockers RAM, which also sets visually decisive accents with unusual heat pipe cooling. The company’s equally well-positioned power supply division is gradually expanding.

The design of the power cars and in this case the CX450 is discreet, completely black and blends seamlessly into the interior. At the bottom works a large 120mm fan and provides excellent cooling at low volume. The fan has an automatic speed adjustment according to the power supply temperature as well as a double plain bearing for a particularly even and quiet running.

This is also ensured by the high efficiency of 85 percent, which was certified with the 80Plus Bronze Seal. Thus, the power supply works very efficiently, so that little heat is generated and at the same time the power requirement is minimized – a blessing in times of constantly rising energy costs. The ATX 2.4 standard of the power supply also provides comprehensive hardware compatibility.

With 450 watts, the power supply is suitable for a variety of applications. In contrast to most other manufacturers, Corsair does not rely on split 12V lines, but on a single single-rail, which is particularly strong dimensioned for it – in this case with 37.4A amperage and 450 watts of power. This also feeds hungry CPUs and graphics cards.

Short ReviewCooler Master is a 1992 company who is well known for computer hardware manufacturing, and mainly famous for its cooling system. Not just the heatsink, Cooler Master also supplies some world class PSUs too.

And this time they come up with the mid-range power supply ‘GX-450′ who is specially targeted for performance, yet with a reasonable price tag.

Cooler Master GX Series power supplies come with a lot of more features too;

like a single highly robust 12 V rail which provides the perfect power to all the most demanding computer components, including the latest generation processors or GPUs and a smart 120 mm FAN which you can control with an active PFC/PWM combo controller for the extended efficiency.

Yes, ‘Extended efficiency’. Here’s the interesting part, the box is labeled with the standard 80 Plus certification but with help of advanced controller, the 80 Plus site itself claims it will do Bronze.

The supply comes with 12 connectors which are more than enough for a 400 Watt PSU. In a box, you’ll find a PSU, a Manual & Business Card and a 1.5M Power Cable with some Screws. So, who can resist 5 years of warranty and a black mat finished look in a 45 dollar price tag.
