Trading Computer Power Supply Selection

If you're in the market for a new Trading Computer, one of the most important decisions you'll have to make is what size Power Supply to get. Power Supplies come in a variety of different wattages, and it's important to choose one that will be able to handle the demands of your system. In this article, we'll give you a few tips on choosing the right Power Supply for your Trading Computer!

Power supplies are often an overlooked element in buying a computer, but it is a very important consideration. When a computer fails, it is often a deficiency in the power supply that directly or indirectly leads to failure. Power supplies use a component called a "capacitor" to smooth out the DC current that goes to your computer's motherboard and other components.

Capacitors gradually degrade over time; they degrade faster with elevated temperatures and elevated workloads. Not all capacitors are created equal finding a good power supply involves looking at reviews and ordering one to check the brand of the capacitors many cheap power supplies will use Chinese capacitors that usually fail at a much quicker rate than the Japanese capacitors used in the higher quality brands. Larger wattage power supplies have higher ratings for their capacitors which helps them to last longer in lighter duty applications. When picking a power supply, you will need to calculate the power draw on your trading computer if it draws 250 watts normally, a power supply of at least 400 watts would be the smallest one to consider. If you want it to last a long time, a power supply of more than 600 watts would be much better. Also, the initial power surge when the computer starts requires a larger power supply.

After considering wattage comes the maximum current that the 12-volt circuit can supply. This is critical in distinguishing a good power supply from a low-quality power supply. 12-volt circuits are sometimes divided into multiple smaller amperage circuits called "rails." For a trading computer, We would recommend no less than 38 amps for the 12-volt circuit and no less than 20 amps for each rail if there is more than one rail. It is preferred to have more than 45 amps total capacity on the 12-volt circuit because many of the better processors and video cards have a high instant starting current. This may trigger the overload safety device when you try to start your computer, preventing it from starting.
