Power Supply Unit Choosing Factors

Here are the four main factors you should consider before you choose what PSU you need for your PC.

i) Power Supply Modularity

A modular power supply means if the cables are permanently attached to it OR you can add and remove cables as per your needs.

If your power supply is modular, it means you have less cable mess inside your CPU, you have lots of options and airflow is not disturbed.

A fully modular power supply is one with no cables attached, you can only add cables which you want to. A semi-modular PSU is one in which some cables are attached and some can be added as per your use.

Whereas, a non-modular one would have all the cables attached permanently spreading a cable mess all around your CPU.

Luckily, all the PC Power Supplies mentioned here are fully modular 😉

ii) Power Supply Efficiency

Like any other electric component or appliance, a PSU also looses some of its energy in the way. So, an efficient power supply unit for computer is one which losses very less amount of energy due to heat and resistance.

This can be very easily checked using the “80 PLUS STANDARD” which promotes energy efficiency in PSU’s. Under the 80+ it has titanium, platinum, gold, silver, bronze and simple categories.

All power supplies rated as 80+ will have an efficiency of above 80% and the higher you go in categories the more efficient it will be. A bronze 80+ will have an efficiency of 80% and a platinum 80+ will have an efficiency of above 90%.

Once again, all of our 750w modular power supplies listed below are 80+ certified.

iii) Power Supply Safety Mechanisms

PSU is directly involved in providing electric power to your PC components, so it comes with some risks like short circuit or sudden change in electricity. In order to avoid these risks, some mechanisms come built-in with some PSU’s. You need to have a look into these safety mechanisms before buying a PSU.

Most common mechanisms are,

  • UVP (Under Voltage Protection)
  • OPP (Over Power Protection)
  • OVP (Over Voltage Protection)
  • SCP (Short Circuit Protection)
  • OTP (Over Temperature Protection)
  • SP (Surge Protection)
  • OCP (Over Current Protection)

All our best 750w power supplies are safe to a very good extent, they comprise of all necessary safety mechanisms.

iv) Power Supply Warranty

Warranty is an important thing, because PSU may not work sometime or it may burn out at times. So should have a power supply with warranty.

Now if you have read the main things to know before buying a PC PSU or if you know in advance and you just want to know what the best PSU is, here are the best 750 watt power supply units for gaming PC in 2020. We rank based on user ratings, expert opinions and proper testing.
