Buying Guide to Pick Best PSU for Gaming
Just like any other component or product, it is essential to consider a few factors while selecting a PSU.
Wattage
The wattage for a power supply unit is the volume of power it can supply. While some PSUs deliver peak wattage, others offer continuous wattage.
It is possible that the power supply wattage you buy is unable to support your entire components. Hence, first estimate the total wattage required for the entire setup. Based on your motherboard, graphics card, fan, disk drive logic boards, and other components, you can pick PSU wattage.
Physical Structure and Shape
You must have read the term ATX in the above-mentioned models. The ATX uses single 20 – pin power connectors and it is a mainstream that uses 4 pin +12V connector to offer exclusive power to the processor.
Before you purchase a PSU, just ensure it perfectly fits into your PC and is an ideal match to other components of your setup.
Modular Cables
PSU comes with cables, which can be fully modular, semi modular or non-modular. Depending on your unit modularity, you can pick up a PSU accordingly.
- Fully-Modular – This form of PSU comes with no pre-attached cables. As a result, you can make a setup as per your preference availing a clean and clutter-free look.
- Semi-Modular – Such PSUs are connected with only essential cables like cables for CPU and motherboard. They are usually the most preferred ones and offer a less clutter and clean look along with better flow of air throughout the rig. The cables for other components like SATA are detachable.
- Non-Modular – Managing non-modular cables can be highly tricky. It is because they are pre-attached with all possible cables, which means you cannot make any customizations. In most of the cases, your setup may also appear cluttered and messy.
PSU Connectors
In order to gain the best performance with your gaming gear, all components of your setup must easily link to your PSU.
For example, a motherboard will usually require a 24-pin connector while a CPU requires 2-8 pin connector. The graphics card requires a 4-12 pin connector and SSD or Hard Drives require a SATA connection.
Before you buy a PSU, it must come with suitable connectors for all your PC components.
Understanding 80+ Efficiency Rating
The efficiency rating of a PSU determine the power it supplies to the internal components. Most of the PSUs boast of delivering 80+ efficiency rating.
The 80+ is a certification used by manufacturers to confirm their PSU’s efficiency.
The 80+ efficiency rating can be Gold, Platinum, Bronze, Titanium or White.
For a high power supply, it is best to pick PSU with 80+ Platinum or Titanium Efficiency Rating.
Power Rails
PSUs can be single-rail or multi-rail designs. A single rail supplies power from a high power +12V rail to various components of your setup. Alternatively, a multi-rail supplies power from two or more +12V rails.
Stability
It is essential that your PSU delivers a consistent power supply. If the power supply is unstable, it may shut down or render low performance during heavy use or under high temperatures.
Safety
It is best to pick a PSU that is equipped with sound safety mechanisms such as UVP or Under Voltage Protector and OVP or Over Voltage Protector.
Conclusion
Even if you buy a budget-friendly PSU, it would not blow off in just one game. However, to avail of long-term benefits and consistently high results, it is best to invest in an expensive PSU, which offers true worth for your money.
Hope you have an amazing gaming experience with your new PSU!
