The Best PSUs For Your Gaming PC in 2024 (2024)

Power Supply Units (PSUs) are responsible for giving life to all the components inside a PC. They supply power to the CPU, GPU, storage drives, motherboard, and all components connected to the motherboard. With CPUs and GPUs getting more powerful every generation, the amount of wattage they need also increases. The wattage has historically been an ever-increasing value, requiring steadily more powerful PSUs as components evolve. PSUs come with different power wattages and ratings that reveal how reliable and efficient they are. More on that later.

Although it can be easy to underestimate the value of a power supply, its utility can be seen in a myriad of ways. A reliable PSU should bring plenty of stable power to components, allowing graphics cards and processors to run at full capacity, without the worry of undervolting. Generally, failure to provide enough wattage to PC components will result in a noticeable decrease in performance, or worse yet, permanent damage.

The MSI MPG A1000G PCIE5 PSU ticks all the right boxes and then some when it comes to being the best PSU for gaming for a current and next-generation gaming PC build. The 1000W PSU is ATX 3.0 compliant and comes with a native 16-pin 12VHPWR connector. It is capable of providing the full-spec 600W that the connector is capable of driving, making it an excellent PSU to get for an RTX4070TI/4080/4090 GPU.

The MSI MPG A1000G uses excellent internals but arguably goes into something of a fan overdrive when it comes to higher power loads, a common theme for most ATX 3.0-compliant PSUs. This results in audible noise from the PC if one is in a quieter setting. However, the inverse is true if users are running a low load thanks to MSI's Zero-fan mode on a sub-50 percent load with the MPG PSU delivering excellent power without making any discernable noise whatsoever.

As PCI-E 5.0 becomes a more easily available standard, many competitors have lowered prices as newer entries come at different price points, also sporting the newer 12VHPWR connector and being ATX 3.0 compliant. MSI's offering does seem to be one of the more well-received of the dozens of new options on the market. It offers both the new connector and compliance with some of the newest standards. It also happens to be trading at a 15% discount on top of its already reduced price, further cementing its position as an excellent, future-proof PSU for gamers.

It does see competition from significantly lower-priced alternatives with similar specs. This does make it a somewhat less appealing option, even as it comes with higher ratings to balance out its higher price, which should affect its being a top pick in more budget-oriented builds.

Cons

• Somewhat noisier operation when under load compared to competition

$128 at Amazon$135 at Newegg$200 at Walmart

The GIGABYTE GP-UD1000GM PG5 1000W PSU is another of the best PSUs for gaming that is compliant with ATX 3.0 and a native 16-pin connector that allows it to power all the latest and greatest RTX 4000 series GPUs with ease. Priced at just $150 for a premium PC brand, the UD series PSU by Gigabyte checks all the right boxes and some of the wrong ones as well.

While the GIGABYTE GP-UD1000GM PG5 does pass ATX 3.0 specs, it doesn't really go the extra mile. Teardowns tend to show that despite the extensive 10-year warranty, the components inside the PSU are somewhat wanting and result in higher temperatures and noisy operation, making this budget PSU a tradeoff that would work well for most users but may leave power users wanting to consider another option altogether.

The GIGABYTE GP-UD1000GM PSU sees more price cuts as it edges down closer to a sub-$120 price tag at multiple retailers, making it a much more budget-centric PSU than most direct competitors. That's even as it handles anything up to an RTX 4090 with ease, offering a native 16-pin power connector in tow with the rest of the system. This alone allows users to consider grabbing a relatively inexpensive yet compliant option off the shelf for a high-end PC that should handle all current-generation upgrades. And of course, the money saved on the PSU can be invested in other parts of the build.

Those on a strict budget will find that the MSI MAG A850GL PSU checks all the right boxes and makes the right compromises. Even though it's a budget-friendly offering, it comes with everything gamers would need, including an 80 Plus Gold rating, ATX 3.0 compatibility, PCIe 5.0 support, and 850W of power. It has a fairly compact form factor and is fully modular.

The MSI MAG A850GL can handle power spikes from both the CPU and GPU, thanks to its reliable and stable performance output, which is certified by its Cybenetics Gold certification and a gold rating. Under load, the 120mm fan is capable of keeping the PSU cool without getting too loud, which is in part because of the tuning, but most importantly, because of the fluid dynamic bearing.

While 850W may seem low on paper when looking at the competition, it is sufficient for even an RTX 4090. Most RTX 4090s at stock settings will work just fine with an 850W PSU until you decide to push your hardware further and overclock the CPU and GPU. Even then, unless they are both under peak load, 850W should be enough.

Seasonic Vertex GX-1200 1200W PSU

Silent, Efficient, Well-Engineered

$200 $244 Save $44

The Seasonic Vertex GX-1200 is a 1200W PSU that is ATX 3.0 and PCI-E 5.0 compliant as it features the new 12VHPWR connector that powers the latest RTX 4000 series GPUs in addition to premium-grade flat cables and a fluid dynamic bearing fan for quiet operation even as it tightly regulates voltages across the 12v, 5v and 3.3v rails with a 10-year warranty in tow as a testament to how highly confident the Taiwan-based PSU manufacturer is about its product quality.

Cons

• Much more pricier than its direct competition
• Competes with Platinum/Titanium PSUs in its current price range which tend to be more efficient

$200 at Amazon$200 at Newegg$200 at Walmart

No high-end PSU for gaming list is truly complete without a Seasonic product listing, and the Seasonic Vertex GX-1200 1200W PSU makes it very difficult to keep it off. It comes with a PSU tester as part of its neat package while feeling like a premium product thanks to its build quality and finish as well as the internal quiet-but-efficient fluid dynamic bearing fan on display. With a comprehensive 10-year manufacturer warranty coupled with one of the best quality cable sets that the industry currently makes, the Seasonic GX-1200 is a compelling purchase to make for most end-users who continue to put much stock in the brand's penchant for making some of the best PSUs in the industry.

At the same time, the PSU is considerably more expensive than its direct competition in the sub-1000W-1200W market. In fact, it comes closer to its platinum or titanium competition in terms of overall pricing, which might make the case for spending a bit more to get a more efficient PSU instead of an appealing one.

The Seasonic Vertex GX-1200 1200W PSU has seen its previous price cut nullified since Game Rant last looked at it, making it a relatively expensive investment to make yet again, but one that should pay off over time. Given the PSU manufacturer's penchant for delivering excellent PSUs in the past, this does not necessarily have to be seen as a negative. As one of the few PSUs on the list that ships with its own PSU tester inside the box, the attention to detail of Seasonic is second to none, earning them a dedicated consumer base that swears by their products and cementing Seasonic Vertex's position as one of the more durable PSUs.

The slightly lower capacity GX-1000 1000W PSU also packs the same features while trading at a small discount versus the pricier 1200W variant, offering decent value for money at multiple retailers while meeting the needs of most PC gamers and enthusiasts.

• Negligible OTP protection (if present)
• Earlier units seem to have shipped with a defective or poor QC'ed 16-pin GPU connector

As one of the few PSUs for gaming in the market that offers dual 16-pin PCI-E Gen 5 power connectors, the Thermaltake Toughpower GF3 1650W PSU has its work cut out for itself as it aims to deliver as much as a whopping 1200W across two connectors. However, it does get noisy fast, despite its efficient design and high-quality components. The good news is that it's hard to max out this PSU on current hardware, but if users do find a way, it will surely be a noisy affair.

Backed by a solid ten-year warranty, however, the Toughpower GF3 does have a lot to offer if one is in the content creation business or somehow has a reasonable explanation for wanting two RTX 4080 or 4090 GPUs on the same system. It does comply with ATX 3.0 and is available at a reasonable cost. This is not a mean feat by any measure and credit must be given to Thermaltake where it's due.

The Thermaltake Toughpower GF3 1650W has dropped in price slightly since Game Rant last took a look at it, primarily due to more affordable options coming into play in the mid-tier and high-end PSU markets, which are also ATX 3.0 compliant and offer the newer 12VHPWR connector natively. At its current price, it offers astounding value that should, in principle, allow users to run two RTX 4090s in parallel if they need to, making it a powerful fringe-case offering for users needing immense amounts of power or simply future-proofing for the next generation of GPUs.

Users opting for this may want to consider investing in a third-party extender, given the penchant for Thermaltake's own cable to be considerably stiffer than most of its direct competition.

• Excellent amount of power available on a single +12V rail to meet modern GPU needs
• Native 12VHPWR connector on the PSU, a rare offering for the limited-options SFF PSU market
• Much better efficiency than most of its competition with a Platinum rating

Cons

• More expensive than standard ATX-sized alternatives

$270 at Amazon

If the PSU needs to be fitted in a smaller ITX or mITX case that can not house a full-sized PSU, then users must often turn to an SFX or SFX-L form factor offering. The Silverstone SX1000R Platinum is possibly the most complete package one can opt for currently for a Small Form Factor (SFF) build. Being a bit on the expensive side, the Silverstone SX1000R Platinum has a fully modular design and is SFX12V 4.0 (effectively ATX 3.0 spec) and PCIe 5.0 ready. It uses all Japanese electrolytic capacitors that it claims offer better reliability.

Silverstone also offers typical protection measures including over current, over-voltage, short circuit, over temperature, and more. The SX1000R Platinum has an all-black design with large Silverstone branding on one side. It comes with all the key cables. The company says it has a mean time between failure (MTBF) of 100,000 hours, which is effectively ~11.4 years of continuous use, making it a very real possibility that the PSU would outlast most, if not all, of the components it is paired with. With a 0 RPM fan design at loads of up to 200W, this also makes it an excellent SKU to pair with higher-end HTPC builds for users looking to redo their home theater setup, where the silence is a bonus.

For users needing a more budget option, Cooler Master has an excellent 850W PSU that also offers a native 12VHPWR connector for newer RTX 4000 series GPUs while costing nearly half the price, Silverstone's more premium option commands, making it a great mid-range option that can handle GPUs up to the RTX 4080 with ease in most cases.

Buyers who have already zeroed in on a PSU purchase for their system might also want to get a new PC case to go with it. The Game Rant team has an excellent guide to help make a better investment in a new gaming PC or long-overdue upgrade.

How To Find The Right PSU

Given that the best PSU for gaming is the most crucial aspect of a gaming PC when it comes to reliability and ensuring components can both function as intended and are protected from damage in multiple ways, one should always aim to get a quality PSU unit. It should meet or exceed a buyer's needs while being cost-effective and as silent as possible.

Wattage: The PSU is the heart of any PC build as it supplies power to the various components. It takes power from the wall and gives it to the different components based on their needs. Depending on the build and the power requirements of various components like the CPU, GPU, and storage drives, a PC can demand a broad range of power going over even 1000W in certain conditions. There are online tools that can help users figure out how much power their particular build would require and then look for a PSU accordingly. Most gaming needs are covered below 1000W with ease, however, and this is factored in with the choices below.

Rating: Power supplies come with ratings that show how efficient and reliable they are. These ratings include 80 Plus Standard or 80 Plus White, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, 80 Plus Platinum, and 80 Plus Titanium. The standard or white-rated PSU can deliver a minimum of 82% efficiency at 20% load, 85% at 50% load, and 82% at 100% load. On the other hand, a titanium-rated PSU can deliver a minimum of 94%, 96%, and 94% efficiency at 20%, 50%, and 100% load, respectively.

Form Factor: PSUs come in ATX, TFX, SFX, or SFX-L. Most full-tower or mid-tower ATX cases can accommodate most of the PSU sizes, but the same cannot be said for small form factor builds. These builds will need to use an SFX or an SFX-L power supply. The smaller size doesn't necessarily mean a lower wattage, as there are SFX and SFX-L PSUs in the market that can output 1000W or higher.

Modularity: Some PSUs allow users to attach only the necessary cables to avoid clutter and a potential cable management nightmare. These are called fully modular PSUs. Some power supplies come with key power cables connected to the PSU board that are non-removable. Modular power supplies are easier to work with, but they are typically more expensive than non or semi-modular PSUs.

FAQ

Q: What power supply capacity is needed to run an RTX 4080?

The RTX 4080 Founders Edition requires at least a 750W PSU. Game Rant recommends going for at least an 850W PSU, if not a 1000W unit to allow for future-proofing/upgrades down the line. But if buyers want to be as specific as possible about the limit, a high-quality 750W PSU should suffice for an RTX 4080.

Q: What power supply is recommended for an RTX 4090?

Nvidia's official specs for an RTX 4090 GPU state that a minimum of 850W is required. Some AIB partners that offer overclocked versions of the same recommend a 1000W PSU. It would be a smart play to go for a 1000W PSU just to cover all bases and allow some leeway in terms of power draw if needed.

Q: What is the recommended PSU to run an RTX 4070TI?

On paper, an excellent 700W PSU might be more than enough to power an RTX 4070TI, which is rated by Nvidia to have a Total Graphics Power of 285W. Nvidia's own recommendation sits at 700W, but it can't hurt to go a bit higher in order to get more efficient operation from the PSU as well as future-proofing a PC for further upgrades down the line. A 750W or 850W PSU is what Game Rant recommends for the RTX 4070TI.
