Whether you are building a new computer for video games or upgrading your existing PC into a gaming station, you will surely need a compatible power supply unit which will provide reliable current to all the devices in your desktop machine. The purpose of a PSU is to take a AC power from a power plug installed in regular grid electricity in alternate current (AC) form and then use the step down transformer to generate voltage variations into different power cables into direct current (DC) which are then routed throughout the computer case for a constant electricity supply. So basically a power supply box function as an adapter to provide lower voltages.
What are ATX Power Supplies And Cases?
ATX stands for Advanced Technology Extended which is a technology standard set by Intel in 1995 used for building modern PC cases, motherboards and psu, ensuring their interoperability with each other. For example: If you purchase an ATX motherboard from the market, you can be sure that it is compatible with your atx case and can easily install and get power from atx psu. The true essence of ATX is to provide flawless compatibility between the PC equipment.
Powerful PC Base For Gaming = ATX Case + ATX Motherboard + ATX PSU
Which PSU Is Suitable For My Gaming PC?
When you are building a gaming machine you should know how much power your machine will need in order to work flawlessly. It is best to plan ahead and know your power supply requirements in advance because a smaller capacity PSU will cause trouble in future upgrades of your gaming rig. Secondly any power supply never deliver 100% capacity of what it has written on it, for example a 650 Watts PSU will only deliver 500-550 watts so it is best to only consider 70-80% of power efficiency. One question arises here, how can one calculate power needs of a gaming computer? Well there are many calculators available on the internet which can help you estimate the power consumption, however the general rules for estimate are as follows:
For a single GPU go for a minimum of 600-700 watts
If you need dual graphic cards such as SLI or crossfire then it is best to go for minimum of 800-900 watts. Go for 1000+ watts if you need up-gradation in near future.
