FAQ – Frequently Asked Questions


How much wattage do I need for my Laptop-Adapter?
1.) Check the label on the notebook bottom. 2.) Or check the label of your adapter. There you can find easily the data you need to calculate the wattage. Voltage(V) x Current(A) = Wattage (W) Example: 19V x 2.37A = 45W 19V x 3.42A = 65W 19V x 4.74A = 90W Read more [...]


How to choose the right UPS?
Decide between offline, line interactive and online functionality: Offline UPS will only provide back-up in blackout situations. Line interactive will provide back-up in blackout as well as during Sags, Spikes, Surges, Noise and Transient situation. Online UPS provides the maximum level of back-up and protection under all circumstances. Consider the requirements of power quality. Understand the current capacity of UPS and consider the future expanding. Limit your choice to brands Read more [...]
The importance of Power Supplies
The three elements that play a major role in the stable operation of a computer, are its Motherboard, its memory and most importantly its power supply. When assembling a computer, the average computer user is more likely to pay more attention to the role of the motherboard and memory in the stability of the computer, while many consumers are ignorant of the importance of selecting a good power supply. Novice computer users mostly use brandless supplies that come with the case, yet many users do Read more [...]
What are the new trend in Power Supply Units?
In the wake of the emergence of global environmental awareness and the implementation of the European Union environmental policy, the demand for and attention on energy-saving products have become the latest trend. On 27 January 2003,the European Union issued the RoHS (Restriction of Hazardous Substances)Directive, therewith outlining regulations for the use of heavy metals(lead(Pb), cadmium (Cd), mercury(Hg), hexavalent chromium (Cr6+)) and flame retardants (PBB) (Polybrominated Biphenyls) and Read more [...]
What kind of types of Power Supplies available on the market?

The most recent ATX PSU standard is version 2.31 of mid-2008. The standard ATX form factor dimensions are 140(D) x 150(W) x 86(H)mm. However, there are various other form factor sizes such as:

SFX – 100(D) x 125(W) x 64(H)mm
TFX – 175(D) x 85(W) x 66(H)mm
PS3 – 100(D) x 150(W) x 86(H)mm

FSP offers solutions for all these form factors and more.

What are the risks of an inferior quality power supply?
a. Hard disk burnout after power failure! After the computer is turned on and ready, it will send a PG (Power Good) signal to the motherboard. Upon receiving this signal, the system will boot and the hard disk will start to read and write. When at this point there is low voltage and insufficient power, the hard disk will experience an abnormal rotation speed due to which the magnetic heads of the hard disk cannot be suspended to their normal position and will scratch the disk. b. Unstable screen Read more [...]
What you should know about Power Supply Units!
a. The more fan, the better? Fans are relied upon to effectively disperse the waste heat generated by the power supply. In addition to the commonly seen single fan power supplies, power supplies with a double or even triple fan design for even better heat convection and concurrent dispersion of heat inside the computer have emerged on the market. Although in theory better dissipation efficiency can be attained with a larger number of fans, a good case design can actually also successfully dissipate Read more [...]

Do FSP have safety standard certifications?
Our products have passed the safety standards of various countries, including the FIMKO(Finland), NEMKO (Norway), CSA (Canada Standards Association), D (Denmark), CB (International Certification Body), UL (American Underwriters Laboratory), DVE (Germany), TUV (North America), and SEMKO (Sweden) safety standard. They have also obtained electromagnetic compatibility and electromagnetic radiation interference related certification, such as CE (European safety standard for electrical equipment), FCC Read more [...]
What are EMI waves?
"Electromagnetic waves" are waves that are created as a result of the interaction between an electric field and a magnetic field and that move through the air. The way they move can be compared to the wave movement of the sea. Our living space is full of all types of invisible electromagnetic waves, the existence of which we are never aware of. In Taiwan, the awareness of and protection against electromagnetic interference is gradually receiving attention, and although Taiwan has not yet introduced Read more [...]
What is the meaning of this label data on Power Supply Units?
1. Wattage A Power supply can transform alternating current (AC) of the utility power into direct current (DC) required by your computer. Most power supplies provide the computer with +3.3V, +5V, +12V, -12V, -5V power, and we usually use the wattage (watts) to evaluate the power's capability. 2. Capacitance Capacitance plays a very important role in power supplies. A high-capacity filter capacitor can provide the computer with a better and purer input current, which is extremely important for Read more [...]
