If you are based in India and are looking for the best 1200 Watts PSU in India then check our recommendations.
A power supply is an important component for a PC build. It streamlines the efficiency of a device and ensures that all power requirements are met. The power supplied usually lasts for hours. At least one electric load can be operated through a power supply. Most modular PSUs offer excellent energy efficiency. Through 80 plus rating, a power supply is quite efficient to deliver at least 80% of its rated wattage to your device or system. The remaining 20% is dissipated as heat.

How to choose the best Power Supply:
- TDP of CPU – 165 Watts
- Intel Recommendation: 1.25 x 165 = 189 Watts
- The motherboard determines turbo Frequency and Power Limits
- Add the TDP for GPU(s) for the final value to estimate the total power consumption
Also, note that most PSUs (SMPS) are designed to deliver optimal performance at half the rated load. So, it is a misconception to assume that the most powerful PSU will deliver better performance and efficiency. This is because of the power quality and efficiency drop at idle speeds. Say, if your PC is at a 15% load, only an 80+ PSU would be able to deliver the rated capacity.
A single High-End GPU and a matching CPU only needs a 350W 80+ Power supply
Also, do read about Intel’s newest ATX spec (v2.53). It comes with a set of low-load efficiency requirements, which state that every PSU should have higher than 70% efficiency with 10W ( for <500W capacity) or 2% of its max-rated-capacity loads. This provision is valid from July 2020. So every power supply meeting the ATX12V v2.53 spec has to be efficient at more moderate loads, too.
For the 1 kW scenarios, a higher efficiency PSU is definitely recommended given the fact that small losses are actually not so small. So, with this context, the recommendations below discuss the best 1200W 80 Plus platinum full modular ATX power supply:
