The best PSUs for PC gaming — Recommendations and advice

pcinvasion.com:

When shopping for a new power supply unit (PSU) for your PC, it can be a bit of a mysterious process. There are critical points one must consider, such as calculating the total wattage the PSU needs to supply, staying within the efficiency curve, knowing what type of power connectors you need, and how much extra headroom to account for. So, before making the decision of which PSU brand you want, you have to know what components will go into your build, both now and in the future as standards evolve. With all of this in mind, there’s no better time than now to talk about the best PSU recommendations for PC gaming.

Generally speaking, power supply requirements correlate with system component performance tiers. For instance, entry-level systems typically incorporate cheaper, low-power components that don’t need high-wattage power supplies. In contrast, PCs housing the best modern CPU and GPU combos on the market need beefy power delivery to run the components properly.

In fact, choosing the right PSU will be especially important going forward as future graphics cards use significantly more power to drive better graphics and higher framerates. The recently released 450+ watt Nvidia RTX 3090 Ti is evidence of this, and a good example of why you need to choose a PSU wisely.

Before we can hop into specific PSU recommendations, we have to go over power delivery capacities. PSUs are only able to supply a certain amount of power depending on which one you choose. To avoid overspending on an expensive, high-capacity unit, you need to calculate how much power you’ll realistically need for your system.

The easiest way to figure out the PSU wattage capacity you need is to use a power supply calculator. These tools can be found across
