Most often, users tend to disregard the computer power supply unit (PSU), when in reality, it’s actually a vital part of every PC system. Some have the notion that having a higher rated power is better while others pay no attention to it and just depend on what supply comes with the unit when they bought it. It’s just sad to know that people often ignore the advantages of a good power supply for stability and long term reliability compared to more attractive components like SSDs and graphic cards.
The market today is full of substandard computer power supply units but equipping yourself with the right knowledge can help you find and buy the right and most efficient device. Though there are no general directives on how pick an efficient; nevertheless, here are some hints and tips to lookout on selecting a quality PSU.
1. Generic PSU
Avoid purchasing generic and cheap power supplies. Always make sure that it’s from a reputable supplier or manufacturer. Do your homework and research about its product description, specifications, manufacturer and customer reviews. Also, make sure that they offer solid warranties and support.
Most makers of PSU indicate their total PSU power in watts. The more wattage, the more power it can supply. Commonly PSU’s that come with every computer has an output ranging from 200 to 1800 watts. PSU output above these would already exceed the typical 15 ampere electrical outlet. The vital thing to consider here is what power output can sustain continuous power, not the one with peak power.
3. An efficient PSU is a better PSU
Typically, a PSU efficiency rating is vital. The higher the efficiency, the better it is in handling heat. Moreover, it wastes less power and has better components. A rating of 80% means it provides 80% power to the system and 20% of which is heat.
4. The Rail Debate
If you have a single-rail design, all its power supply is accessible to any part connected to the unit, without adherence to the cable or connector employed. If a failure should happen, the single-rail power supply comes with more potential to shoot more current to components. The multi-rail PSU doesn’t have the ability to share power among different rails but if ever a failure happens, this disadvantage turns into something positive. That’s because the OCP mechanisms in a multi-rail power supply monitor each rail and will shut your device down should it detect any overload among the rails.
Power supplies come with hard-wired cabling, whether partially or fully modular. If you have a modular power supply, you can easily add or remove cabling when necessary to prevent clutter. Technically speaking, it’s best to go for a power supply that comes with hard cabling wires because it won’t need any additional connections between internal PCB of the unit and the connector that’s plugged into one of your components.
