It’s been quite a year for power supplies. We’ve seen a bunch of new ATX 3.0 and ATX 3.1 models hit the market, and we’ve tested and reviewed more than two dozen of them this year. Now that things have settled down, I thought it’d be a good time to share my top 6 picks for gaming that really stand out.
With that in mind, I narrowed down my recommendations based on four key aspects: max ripple, voltage regulation, efficiency, and value. The first three are purely for performance and stability, while the value factor is based on how much the PSU costs and how many additional features it brings to the table, like fan noise, warranty, cable type, software, build quality, protection, and more.
If you are interested in any of our recommended power supplies, I highly suggest that you also give a quick read to its individual review, as you will find more information there, including a teardown of the PSU, an in-depth analysis of its internal components, and thermal test results.

Power supplies can have a lot of jargon surrounding them. To help you with your choices, I have mentioned a few key terms you’ll find when on the lookout for a decent unit:
- Wattage: A power supply’s wattage represents its maximum power output capacity, which is measured in Watts (W). The dedicated wattage of a PSU determines its power delivery to components. Hence, it is crucial to match the PSU’s wattage with your PC’s to avoid any instability issues.
- Efficiency: A power supply’s efficiency rating measures how effectively it converts AC power to DC power. Generally, these are the 80+ ratings in order: Bronze, Silver, Gold, Platinum, and Titanium. We recommend looking for 80+ Gold and above-rated power supplies to ensure proper power draw.
- 12VHPWR Cable: Abbreviated as 12-Volt High Power Cable, this is a cable in ATX 3.0 power supplies that helps supply power to high-end NVIDIA GPUs like the RTX 4080 and RTX 4090. Before purchasing, you need to ensure your power supply supports your GPU’s power requirements and connectors.
- ATX 3.0: One of the latest power supply standards (now the ATX 3.1), it handles the high power requirements of modern computers. This is especially true for top-tier graphics cards that require the 12VHPWR cables.
- Voltage Ripple: It refers to the minute fluctuations or variations in the output voltage of a PSU. Voltage ripple is usually caused by AC-to-DC conversion. When on the lookout for a new power supply, ensure your unit’s voltage ripple at 100% load isn’t too high; otherwise, you may face instability issues.
- Voltage Regulation: A power supply’s voltage regulation states how well it can maintain a constant output voltage even when its load changes. For example, the load can change when you plug in more devices or when there is a difference in the input voltage. Tighter voltage regulation equates to a more stable power draw, meaning better overclocking opportunities with the said PSU.
How We Picked The Best Power Supply For Gaming
We tested several power supplies to bring together the best power supply for gaming. Obviously, many factors need to be considered, and I have described a few to help you make your purchase decisions as well.
- Performance: The first thing you need to be wary of when searching for a power supply is its performance. By performance, I mean its voltage ripple, load regulation, efficiency, transient response, and more. A good power supply will be more stable. Hence, we only chose units with the highest performance because what’s the use of buying a high-end PC if you’re going to use a washed-up power supply?
- Modularity: Although it’s not that important, a fully modular power supply helps tremendously with cable management because all of its cables can be detached. This way, you only need to plug in the cables you require and stash the others whenever necessary. The good thing is most decent power supplies these days are fully modular, so you won’t have to worry about much.
- ATX 3.0/3.1 Compatibility: Most new graphics cards require ATX 3.0 compatibility. Even if AMD GPUs don’t have this requirement, it’s better to future-proof your system by purchasing a new power supply with the latest frills. Therefore, we only selected PSUs that match this compatibility requirement.
- Build Quality: A good power supply will have a sturdy and decent build quality that matches its warranty period. Hence, in all of our power supply reviews, we do a teardown analysis to look at the internal components. A power supply is only as good as its capacitors and internals. Hence, we only chose the ones with the highest build quality.
FAQs
What is the wattage sweet spot for a modern PC build?
If you’re worrying about future-proofing, a 1000W power supply is currently the sweet spot. Otherwise, you can also run most hardware with an 850W PSU without facing any instability issues.
Can a gaming PC last 10 years?
Depending on how well you maintain it and your personal use case, a gaming PC can technically last 10 years. We recommend upgrading it once every three to four years. Still, you shouldn’t face any problems as long as you properly maintain it and re-apply thermal paste wherever possible.
Is it OK to buy a cheap power supply?
No. We never recommend cheaping out on a power supply. If you’re out of budget, then cheap out on another component, but don’t purchase a bad power supply. This is the backbone of your computer; all of the electricity passes through this component. If there are any issues, you can fry every component on your PC.
