You’ll also want to consider the continuous power versus the peak power capabilities of your new PSU. That said, there’s no real advantage to having a vastly overpowered PSU if your system doesn’t need it, so you might be better served selecting a feature-rich, high-efficiency PSU that is closer to the wattage you require. Higher wattage output doesn’t necessarily mean more energy consumed it means it has the ability to provide more power if your system demands it. If your system is drawing 500 watts, your power supply will supply 500 watts, regardless of maximum capable output. Keep this in mind when considering higher wattage PSUs: a 750-watt power supply does not consume 750 watts by default. If you’ve calculated that your system is going to use 500 watts (a common number for a straightforward gaming build), choosing a PSU with 600 or 650-watt output could be a good option, as it will give you some overhead to work with, and also allow for potential future upgrades. It’s impossible to give an exact recommendation without knowing specifically what hardware you’re working with, but using a PSU Wattage Calculator, or determining the power draw of your different internal components and adding that together, can give insight into how many watts you need.Īs a general rule, it’s better to err on the side of higher wattage rather than trying to match your needs exactly. A desktop with a custom liquid cooling loop, a high-end motherboard, and dual GPUs is going to need a higher wattage computer power supply than a simpler system. Generally, more complex systems require more power to run.

When selecting a new PSU, one of the most common questions asked is, “How many watts is enough?” As is often the case in the world of PC hardware, the answer varies widely depending on the unique needs of your system.
Molex connectors are usually found on less common accessories, such as water cooling pumps
Most PSUs address this required flexibility by providing cables that can be used in a variety of combinations, some of which include 6, 8, 6+6, 8+6, and 8+8, and even 8+8+8 pin connectors. 6/8 pin (PCIe*/GPU): Some GPUs draw enough power from the PCIe* slot, while others require a specific power cable configuration to operate properly.Though it can vary depending on the manufacturer, the CPU cable usually plugs into the top left side of the motherboard, near the I/O on a standard layout Modern CPUs draw more power than the 24-pin motherboard configuration can provide, which is why the additional 4/8 pin cable came into use. 4/8-pin CPU: This connector provides power to your CPU.24-pin Motherboard: The way power is allocated varies from motherboard to motherboard, but the 24-pin connector/cable is frequently used to power important features such as the chipset and PCIe*.The exact cables you’ll use will vary depending on the specifics of your build, but you’ll most likely be dealing with the following:
Though the PSU you purchase should come with all of the cables you need, it’s worth knowing what the individual connections look like. Let’s kick things off by going over the different cables power supplies use to provide power to your system.
