PSU – Heart of the PC
The power supply unit (PSU) is probably the most neglected component on the PC.
When buying a computer, most users will consider it as the least important part and will just place it at the bottom of his consideration list. Example:
1. Processor (CPU)
2. Motherboard
3. Video card
4. RAM
5. HDD (Hard Disk Drive)
6. ODD (Optical Disk Drive)
7. Casing
8. PSU
Majority of the budget will be used to purchase the top hardware and what remains would go to the PSU. Most of the time, users would just buy a casing with built-in generic PSU.
We forget to remember that the PSU is the one that “fuels” all those PC parts. If the processor is considered as the brain of the PC, the PSU should be considered as the heart of it, supplying “blood” to your hardware. A good-quality PSU can increase the durability of your equipment and reduce your electricity bill.
On the other hand, a low-quality PSU can cause a variety of problems that are mostly difficult to solve.
