Thermaltake Litepower 550W Power Supply
There is no point in buying a PSU with way more potential power than you’ll ever use. A PSU calculator web page or software can be handy in finding a rough estimation about the wattage requirement of your build. However, it is not recommended purchasing a PSU just above your system's power needs.
A PSU delivers maximum efficiency with 40 to 60 percent load. Besides, the performance of a PSU declines with time. So, you better opt for a PSU capable of taking you through your next few upgrades for multiple years.PSUs convert voltages from wall outlets to lower levels as required by the PC. The power supply wastes some power as heat during the conversion.
A PSU with higher efficiency means it can power the PC with minimum loss of electricity. Anything 80% and above is good. With a more efficient PSU, you can end up saving money as it will require less electricity to power your PC. The "80 Plus" Certification shows that the power supply has been tested to have 80% efficiency at every load. There are higher tiers of 80 Plus that show even higher efficiency such as 80+ Bronze or Silver. As the efficiency of the PSU gradually drops during the lifespan of the PSU, it is recommended to opt for a PSU with the maximum efficiency possible as long as it agrees with your budget.
