Which PSU is the best in terms of Job Location?

Even though it doesn’t get much attention, the power supply unit (PSU) is an important part of every desktop PC. If you choose the wrong power source for your whole system, it could cost you. We’ll talk about the basics of power supply so you can understand how important it is to choose the right model and why going with the cheapest option isn’t always the best.

Always in touch

First, look at your power supply’s different cables to send power to your system. You should still familiarize yourself with the appearance of the various connections, even if the power supply you purchase already has all the wires you’ll need. Depending on your setup, you may need different wires, but you’ll probably need the following:

A motherboard with 24 pins:

Each motherboard has a different way of getting power, but the 24-pin connector or cable usually powers important parts like the chipset and PCIe.

CPU (4/8 pins):

Your processor gets power from this port. Modern CPUs need more power than the 24-pin motherboard architecture can provide, so adding a 4/8-pin cable makes sense. Depending on the maker, the CPU cable may be near the I/O on the upper left side of the motherboard.

6/8 pin GPU/PCIe:

Some GPUs can get enough power from the PCIe slot, while others need a certain arrangement of power cords to work right. To meet this need for adaptability, most PSUs come with cables that can be set up differently. Some cables have 6, 8, 6+6, 8+6, 8+8, or even 8+8+8 connectors. Most power supplies have many connections on a single wire to save money on wiring. Most people who use it think it works like a multi-cable setup. Please ensure the power supply has the connections your GPU needs before buying it.

The capacity of SSD:

The power for SATA storage devices comes from this connector, and the standard has since been used by other parts, like RGB hubs and fan controllers. Many power supplies have more than one SATA port on a single wire to reduce the number of cords needed.

Molex four-pin

The SATA standard has taken over most of this old’s work and has become less common. Molex connectors are often used in water cooling pumps, one type of accessory.

How much power does it have?

It is one of the most common questions when shopping for a new power supply. In general, systems that are more complex need more power to work. A desktop PC with two graphics processing units (GPUs), a high-end motherboard, and a custom liquid cooling loop needs a more powerful power supply than a system with fewer parts. Without knowing what hardware you’re using, it’s hard to give specific advice. Use a PSU wattage calculator or tally up the power needs of all your internal components to estimate how much power you need.

Most of the time, it’s better to aim for a higher wattage than to meet your exact needs. If you think your system will use 500 watts, which is typical for a basic gaming setup, buying a PSU that can put out 600 or 650 watts might be a good idea. It gives you room to move and lets you plan for future growth.

When thinking about power supplies with more watts, remember that a 750-watt power supply does not always need 750 watts. If your system needs 500 watts and your power supply gives out 500 watts, it doesn’t matter how much it can give out at most. Since higher power output doesn’t always mean higher power consumption, the power supply can give your system more power if needed. But if your system doesn’t need it, a significantly better PSU won’t do you any good. So, it’s best to choose a PSU that is close to the amount of power you need and has many features.

You should also think about how much power your new power source can provide all the time, not just at its peak. Peak power is the most power that a power supply unit (PSU) can give for short periods. Continuous power is the amount of power the PSU is made to give all the time. When the system is used to its fullest, like when running demanding games or hardware benchmarks, peak power is often reached. Your power supply must be able to handle this higher output for a short time if the power demand suddenly goes up, but it can’t do this all the time. Always consider the power output of a power supply, not only its maximum output, before making a purchase.

Platforms

System safety should not be ignored when large amounts of energy are involved. A good power supply should have built-in safety features to protect the power supply and your system in case of an unexpected power surge or something similar. The only parts of a PC that are directly connected to almost every other piece of system hardware are the power supply and the motherboard. Because the power supply is unique in the computer, ensure it has built-in protection for the other parts.

It is important to understand any built-in safety features, such as OVP, which turns off the power supply if an overvoltage is detected. Short circuit protection is another safety feature that comes in handy when the voltage changes. Connect your PC to a surge protector as well. These hardware-saving devices are made to keep dangerous power surges away from your most important parts, giving your system an extra layer of protection.

The value of doing things well

Wattage is important when choosing a power supply for a desktop PC, but so is how well the PSU works. A bad power supply wastes power and makes more heat, which can shorten the life of components. Because this factor is so important, a simple, fair way to score it has been made. You may have seen the “80 Plus” rating next to a precious metal on many power supplies. A power source must be at least 80% efficient, meaning no more than 20% of the power should be lost as heat.

This efficiency level is based on how well a 115V system works, and the ratings go up as the precious metal scale increases. Your power supply will use less energy and give off less heat if it is more efficient. But you have to find the right balance because, generally, being more efficient costs more money. Even the most energy-efficient power supply makes heat, and most need fans to get rid of it. Many power supplies are set up so that the fan only turns on when it needs to or when the power supply reaches a certain level.
