A Buyer’s Guide to Choosing the Best Power Supply Unit

While there’s nothing glamorous about a power supply unit, a power supply unit is one of the most vital components of any computer system. It splits the power and feeds it to various components in a PC, and while an 80% efficiency in a power supply unit is considered to be terrible, modern advancements in technology have addressed these issues.If you are looking for some of the best 80 plus gold edition power supply units that give a stable voltage output, then look no further. We have prepared the ultimate buying guide to educate you on choosing a power supply unit suitable for your PC.

Picking a power supply can seem like a daunting task. You need to consider a few factors before purchasing a power supply unit, such as size, wattage, and efficiency. 

Things to Consider 

The efficiency of a power supply unit

All the power supplies nowadays come with an 80 plus tag on them. The 80 plus tag signifies an efficiency of at least 80%. These days, 80% efficiency is nowhere near enough to cope with all the enhanced tech and hardware components we have. As a result, we now have 80 plus power supply units that come in different colors or grades, such as titanium grade that provides an efficiency of up to 94%.


The wattage of your power supply unit can vary. It can offer you 350 watts with all the different grades available all the way to over 1000 watts. It all depends on how much wattage your system requires.

Fan noise

Power supply units generate a lot of heat due to the constant exchange of voltage. For this reason, they need efficient fans to help keep them cool, especially during heavy loads. Though your power supply unit can be kept cool with large fans, they tend to be quite noisy. This is why you must consider purchasing a power supply unit that has large fans yet spins at a much slower pace. 

Types of Power Supply Units


A hard-wired power supply unit is the kind that has a fixed number of wires attached to its box. You cannot remove or add more wires to the power supply unit. Such a power supply unit is inadequate for good cable management as all the extra cables that aren’t being used are just floating around inside your system.


A semi-modular power supply unit is the type of power unit that typically has one fixed wire attached to its box. Since the rest of the cables can be attached separately, its design eliminates unwanted wires—creating a more open space and allowing for a more enhanced wire management experience within your system.


A full-modular power supply unit is the type that has no fixed wire or wires attached to its box. All the necessary cables can be separately connected to the power supply unit, creating the best-seen cable management opportunity.

Pystar’s 850 power supply unit is a power supply unit with a full-modular design and black cables.

It has an extremely quiet 140mm fan that can dissipate heat at a good pace while making no noise. Keeping the power supply unit temperature low, this power supply unit has a DC-DC structure that makes the voltage output more stable and safe to use.
