Best Portable Power Supplies Buyer Guide

Although often not given all the importance it deserves, choosing a PC power supply can have a significant influence on a computer’s performance.

Therefore, it is not convenient to give in to the temptation to buy one of the poor quality and, consequently, cheaper, to slightly increase the budget to be allocated to other components.

As the saying goes, virtue lies in the middle. If you are thinking of mounting your computer piece by piece, it is essential to install a suitable power supply and take into consideration any expansions you want to make on the device. Choosing the correct power supply, however, doesn’t just mean buying the most powerful model.

The Most Affordable Rgb Lighting Option

The 700W Thermaltake Smart RGB is the ideal solution for those who want to illuminate the interior of their homes, without spending vast amounts of money.

Thanks to a button located on the back and accessible from the outside, it is possible to set a fixed light or a cycle of all colours, or even turn it off completely.

Buyers are enthusiastic about the aesthetic value of the product, although it is not modular; the lighting configuration is independent of the motherboard, which has its advantages and defects.

Purple Leaf Universal Notebook Power Adapter

From first glance, this power supply stands out for an important detail: it is ultra-thin. Thanks to this peculiarity, it takes up very little space and is easily transportable, with the possibility of storing it even in your handbag: it is also very light.

It is a high-efficiency model, with a maximum power of 90 W; it is also compatible with 70 W, 65 W and 45 W. Safe and reliable. It is designed with a 13-pin DC plug-in connector, which ensures a full possibility of use with the main laptop models on the market.

The input is AC 100-240 V 50-60 Hz; the output is DC 15V-20V / 4.5A. To further increase the versatility of the device is the USB port 5 V / 2.1 A. Together with the power supply, the package contains an AC power cable, a DC power cable, 12 extra tips.

The Best Mid-To-High-End Gaming Pc Power Supply

The Asus ROG Strix 650G is one of the best proposals regarding the 650 W range, the one most commonly adopted for gaming PC configurations with a medium-high range video card.

It has an 80 Plus Gold certification, is entirely modular, and has a fan that buyers call silent even during the most stressful sessions. It’s a bit longer than the cheaper proposals, but it offers first-class reliability and connectivity.

Kensington

It takes just a few simple steps to configure this power supply. All you have to do is check the voltage value of the original power supply and, based on this, set the appropriate switch on the device.

Black in colour, the device weighs 499 g and has a size of 1.9 x 13.3 x 7.4 cm. It protects against overcurrent, overvoltage, short circuits and excessive temperatures.

What Exactly Are Portable Power Supplies?

The power supplies have the task of transforming the alternating current of the electrical network into direct current, that is, that used by the various components of the computer. In this way, they meet the energy demand of each of the elements of the device.

Therefore, the power supplies take an alternating current of 115/230 V and transform it into low voltage direct current which they distribute through various outputs. Therefore, if the processor is the brain of a computer, the power supply can be considered its heart.

If you are looking for an inexpensive power supply to save on other components, there are not many options at the moment.

Connect with Sata Cables

We, however, recommend the EVGA 500 B1. It costs less than a video game and boasts 500 watts of power transmitted through six SATA cables and two PCIe cables.

This is, without doubt, one of the best power supplies because it is essential and honestly does its job. Even the three-year warranty does not hurt.

Unfortunately, power supplies don’t always fit into smaller homes. However, Silverstone SFX SST SX550 is a compact power supply also ideal for mini-ITX homes.

Its dimensions are approximately half compared to the standard format and consequently guarantee a better airflow. This makes it a convenient choice for anyone who is building a mini ITX or micro ATX build, but it is also suitable for larger homes.

Small form factor PCs are in high demand, so we could not exempt Silverstone SFX from our guide.

How Does a Portable Power Supply Work?

Current power supplies work by converting all alternating current (AC) to direct current (DC) of +12 V. Then, other converters transform part of this DC from +12 V to DC from +5 V or +3.3 V to depending on your needs. This system is much more efficient and safer than direct conversion from AC to different DC voltages.

Subsequently, a series of inductors and capacitors has the task of filtering the electrical noise that can damage the different components of the device.

Also, the power supply must make a voltage adjustment to respond to changes in load (consumption) to which it is subjected.

If you are attentive to the design of your PC, a modular power supply is mandatory: you can avoid the mess generated by unused cables as well as improve the airflow in the case. NZXT E650 is meant for this.

Not only is it a completely modular power supply, but it’s also lovely to look at. All this is completed by the 80 Plus Gold certification and by a ten year guarantee.
