FSP Engineering Driven Quality
With the concepts of environmental protection and material recycling in mind, the FSP Group is the first to introduce a low-waste of solvents containing fluorine (bromine) has been banned from materials and manufacturing processes, the use of chemical compounds containing heavy metals, (such as cadmium, lead, mercury and hexavalent chromium) for casings has been restricted, and used material have been reduced by 600grams, substantially eliminating weight of any electronic articles that are discarded for recycling. The superior high-performance active PFC circuit design of our various power supplies delivers a performance of 85% at full speed, while the low power consumption design of less than 1W in the standby mode considerably reduces electricity costs, making this a truly environmentally friendly product of superior quality.
Seeking stable operation of computer systems and even higher performance, great expectations and demands are placed on power supplies, that have seen a development from low to high wattage, from general output to high performance, and from noisy to silent products. End-users have of course reaped the most benefits from advancements in product technology and design. With high-standard and economic power, our lives have undergone considerable transformations, and FSP has placed its part in being a responsible product developer.
Electronic components are affected differently by the different designs of power supplies, therefore, in case of any slight problem occurring when the power supply is transforming utility power (AC current) into +3.3V, +5V, +12V current useable by the computer, the power supply may not be able to operate normally. Or, in case of poor design of the power supply, under certain circumstances it may result in an unstable electric current and insufficient power supply. The computer may seem to operate normally, but in reality the life-span of peripherals is gradually shortened. Therefore, when assembling or purchasing a computer, it is advisable to choose a power supply with a good reputation for quality and to avoid those power supplies that come with the computer case, unless of course you can be sure of the quality of that particular product.
What You Should Know About Power Supplies:- How to Recognize a Good Power Supply
Unstable screen picture
Using an inferior quality power supply may influence the AGP display, giving a rippled or unstable picture. If a problem with the display card is ruled out, the problem most probably lies in an unstable power supply to the motherboard.
Overload causing burnout of chips, cards and/or motherboard.
Sudden cutoff from power supply or computer shutdown due to power failure. Nose of the peripheral hardware, nor the CPU, memory, motherboard and display card, will be able to work normally. As the +5V and +12V output voltage terminals of an inferior quality ATX power supply use the same voltage regulator circuit, it may occur that a higher +5V load causes a higher +12V output voltage. Since most chips, cards and motherboards require a +12V power supply, a substantial increase in the +12V voltage of an inferior quality power supply may lead to burnout of these components.
Excessive Noise of Sound Card
Inferior quality power supplies are well below the standard for electromagnetic screens and current output purity. In such a power environment, they can hardly be expected to produce a nice sound. False and deceitful label specifications of inferior quality power supplies lead to unexpectedly frequent re-starts of the computer.
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, +5.5V, +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 the stability of the computer. If the input current is not pure, this will lead to chaotic signals, interfering with the normal processing of signals by the computer and causing instability. Many cheap power supply manufacturers use low-capacity filter capacitors to cut costs, resulting in the computer's performance falling short. There are even inferior quality power supplies that pose the risk of an exploding capacitor when the computer is struck by lightning or affected by any other unexpected impact.
3. Output: AC inputs stands for input from the external power source (utility power), in Taiwan 110V, and the specification is therefore 115V (+-10% margin). The 230V specification is for use abroad, while amperage and frequency are relevant corresponding specifications. The voltages supplied by the power supply after transformation of AC current into DC current useable by the computer and most important to gamers, are +3.3V, +5V and +12V. The +3.3V and +5V are usually required by processors, chipsets, display cards, and PCI and USB devices, while storage devices, CD-ROMs etc. need +12V. Users, and in particular function, must also pay attention to the +5Vsd (standard power) indication, because the WOL function, for example, requires a power of voltage (HV) equipment such a high-end high-speed processor with a high-end display card, choosing a high quality power supply is of crucial importance. The data provided on bales of power supplies available on the market are not always identical. As each manufacturer may be different ideas, labeling often seems ambiguously unclear. There are manufacturers that indicate the maximum power of a continuous output, while other indicate the peak surge output. As long as there is not set norm, through the indicated specifications may be similar, some power supply brands will show no problem in case of overload, while others will stop working altogether after only 1 or 2 seconds of overload. Imagine if we were to compare the other detailed output specifications, short circuit protection data, etc. of power supplies and take into consideration factors such as power quality. Therefore, choosing a high quality power supply is extremely important!
4. Input Voltage Range: On the label, the indicated input voltage range is usually 100-240 Vac, which covers global commercial voltage levels.
5. Input Frequency: The commercial range for input voltage frequency is usually 50 or 60 Hz, while electrical specifications are usually 47-63Hz.
6. Efficiency: Efficiency = (output power)/(input power), the input-output surplus becomes energy.
7. Turn-on Delay Time: The time that it takes for the output voltage to reach a stable voltage range after the system is powered on,
8. Hold Up Time: The time during which the output can be maintained after the system is powered off.
