What should I look for when buying a power supply for a computer? Four key points to buy a computer power supply
What should I look for when buying a power supply for a computer? Recently, some users are planning to buy a power supply for a computer, but do not know what parameters to look at, so today I will introduce you to what you need to pay attention to when buying a power supply for a computer.Power calculation
If power supply is low, your computer will most likely restart or crash. How to make sure that rated power of purchased power supply is sufficient? This requires special calculations. The maximum power of processor and graphics card can be found in product introduction, and other equipment such as motherboards, fans, memory, hard drives, etc. Just add up and sum up.
After calculation is completed, select power supply according to result, but please note that rated power of power supply must be higher, and it can not be just right, this is also to reserve a certain space for future upgrades.conversion efficiency
Now you will buy power supplies with 80PLUS logo, which are divided into six types: white, copper, silver, gold, platinum and titanium. The conversion efficiency is getting higher and higher, and heat dissipation is getting lower. and below. Usually a gold medal is chosen.Output voltage +12 V
You should also pay attention to output voltage. The single +12V output is suitable for gamers and can provide stable power for flagship graphics cards, while dual +12V output is suitable for users who like stability. The load on motherboard is small and lifespan is longer.powerful cooling
The power supply's heat dissipation is entirely dependent on its own fan. The internal structure of a good power supply supports independent heat dissipation. It uses dynamic temperature control and can adjust fan speed to change heat dissipation efficiency. Also, when installing power supply, it's best to choose a chassis that can fit power supply underneath to avoid heat dissipation affecting interior of chassis. In short, farther away from processor heatsink is, better.
