|Question: How do you choose a power supply ?
supply is one of the most important components in a computer. When a power
supply is dead or overloaded, your entire system is dead or becomes unstalbe. A bad power supply could
also cause other parts of your system to fail. As personal computers
become ever more powerful, the importance of a reliable power supply is
more than ever before.
But yet the power supply is
often the least appreciated due to the widespread mislabeling in wattage rating. The wattage rating of a PC power supply is not officially certified and
is self-claimed by each manufacturer. The more reputable makers
advertise "True Wattage Rated" to give consumers the idea that they can
trust the wattage advertised. It
is important to use a reliable power supply from a reputable maker that
conforms to True-Wattage Rating so that user does not add more
components to the system, with false confidence, to overload the power
It's easy to tell if a power supply is
working or not. However, until now it has been hard for a PC end-user
to measure the quality and reliability of a power supply. Based on the return rates and
general experience we accumulated from many years of selling and
servicing power supplies, we have these general observations:
- Sellers that carry True Wattage Rated power
supplies are more open about disclosing the brand and model number of
the power supply that they are advertising.
- Generally, the Intel/AMD/nVidia-approved
power supplies weigh more than the non-vendor approved of the same
wattage, confirming that vendor-approved ones are of better quality.
It's possible that manufacturers only submit better models for the vendor
- The name-brand power supplies typically weigh more than the less-known, generic brands of the same wattage.
- FCC approved power supplies often weigh more than those without FCC labels.
