So you should be careful when it comes to picking the right PSU for your system. The best power supply should also have features to save your system's parts including the power supply itself , in case something goes wrong with your electricity supply or other components.
If it doesn't, it's clearly not the best power supply and is putting your other expensive PC parts at risk. You'll also have different concerns, of course, depending on whether your power supply will be pushing a monster mining rig, an always-churning workstation, or a basic productivity or gaming PC. First, figure out your wattage requirements. You can calculate roughly how much power your new or upgraded system will draw from the wall and look for a capacity point that satisfies your demands.
Several power supply sellers have calculators that will give you a rough estimate of your system's power needs. You can find a few below:. A few years ago, all graphics cards on the high-end of our GPU Benchmarks hierarchy were very power hungry. But this has changed with Nvidia's recent architectures. Check the physical dimensions of your case before buying.
But many higher-wattage PSUs are longer than the typical 5. If you have a particularly tiny or slim PC case, it may require a less-typical and more compact SFX power supply. We have picks for this form factor below as well. Want a clean build or working in a tiny case? Consider a modular power supply. Modular PSUs let you only plug in the power cables you need and leave the rest in the box. On the other side, it has a more-aggressive fan profile, so its noise output is increased.
In the US market, you will only find the CWT version, which is made in Vietnam instead of China, so it avoids the tariffs and keeps its price tag low. Read: Corsair CX Review. Another decent alternative if your budget is low, you need more than W of capacity, and you aren't that concerned about efficiency or some fan noise under load is the Corsair VS You may also be able to save on these or other PSUs by checking Corsair coupon codes.
It would be nice if Corsair added a second EPS connector in this unit, but most folks will be more than satisfied with the connection options. Read: Corsair RMx Review. It also has a silent operation, thanks to the relaxed fan profile, despite its compact dimensions.
The build quality is high, and the provided warranty meets the competition's offerings. Finally, the two EPS connectors provide compatibility with the high-end mainboard, but they should be installed on dedicated cables—all in all, an excellent power supply. It wasn't easy to deliver a better product than the existing RMx , but Corsair managed to do this, and the new model achieves notably better performance.
Compared to the previous model, it loses in quietness, but you cannot call it noisy with 28 dBA overall noise output. Modular power supplies come with one big upside and one downside. The upside, obviously, is that modular power supplies are easier to work with. The downside is that modular power supplies cost more than non-modular power supplies.
So, some first-time builders who are working with a tight budget may have to choose between paying more for a modular power supply or saving money and getting a non-modular power supply. So, the bottom line is that, whether or not you should get a modular power supply will come down to how much you have to spend on a new build or upgrade, and if you have a tight budget, whether or not you are willing to sacrifice some convenience and aesthetics in order to put more money towards other components.
So, in short, yes, you need a solid power supply if you are planning on building a gaming computer. You could just as easily get a decent WW power supply.

Really, the power supplies in this range are monsters and are best suited for enthusiasts looking to build extreme setups.
With W of power, an 80Plus Titanium rating, and Learn More. Now, though, it seems like every power supply they make is winning awards and being raved over. The W T2 sports a whopping Essentially what that means is that the Corsair AXi is one of the most efficient power supplies on the planet and rightly deserves a spot as a tier 1 PSU.
It delivers the stable output you expect from the Seasonic Prime series. The built-in mm fan and year warranty set it apart from others in this category. The fully modular cables give you full control over your build, and the gold-plated connector terminals give you increased overall power efficiency by lowering transmission resistance. Seasonic achieves their near perfect violate regulation under 0. While it is pricier than its predecessors, it comes with a year manufacturer warranty which is one of the best the industry.
There is the P2 version platinum that costs quite a bit less, though, that should work well for most users. The T2 comes with a very respectable And, with a year warranty you can rest assured that this will be the only power supply you have to buy for the next decade or so….
It is a very efficient unit unless tested at higher ambient temperatures and loads. Corsair succeeded with a highly efficient and well-made product—and at an affordable price for what it delivers. At the high end, this PSU is aimed at the serious gamer. In terms of performance, it operates efficiently even at low loads. The overall design is mean without going over the top.
And, these units will give you plenty of headroom to build a ridiculous setup. With Again, I could also include the SuperNOVA P2 on this list, as it will offer similar performance, but it has a lower efficiency rating and so I wanted to include the best option possible. Ultimately, though, the W T2 offers an incredibly efficient power supply that has the ability to run just about any dual video card setup you could possibly want to go with.
Or, in other words, EVGA is so sure of the product they are selling, that they are betting on it not failing after an entire decade of use. And, despite not earning as high of an efficiency rating as the EVGA unit listed above, it does come in at a lower cost.
Another phenomenal power supply for all of you Corsair diehards out there is the Corsair AX It comes with 71A on the 12V rail, a 7-year limited warranty, and a fully modular design… or, in other words, even if you want to build the best gaming PC possible with a single video card or even dual video cards , then this unit will be more than enough for your needs. It has 70A on the 12V rail, it comes fully modular, and it achieves the 80Plus Gold rating.
It also comes with a 7-year warranty. Ultimately, it is another solid tier 2 PSU option to consider if you need the best power supply for gaming. So, that makes PSUs in this range great for anyone who wants the option to upgrade in the future. However, even if you do want to use a high-end video card like the RTX Ti, a quality watt power supply will give you enough power as well.
EVGA has a ton of quality power supplies in the W range. Ultimately, though, with But, that also makes it quite a bit less expensive as well. It has 63A on its 12V rail and will power any single graphics card setup out there and just about any dual graphics card setup as well. While the SN P2 does come with the higher Platinum rating, 80Plus Gold rated efficiency will still suffice for the majority of system builders.
Corsair is a popular brand for a reason and they do not lack for a large crowd of loyal fans. So if you are one of those loyal fans, the Corsair RMx is definitely a solid option…. The one downside, though, is that the unit is not fully modular. We originally had the SeaSonic S12G unit here, but it has since gone out of stock. No worries, though, as the SeaSonic FOCUS is essentially the same power supply, but a bit newer, and it is semi-modular instead of non-modular.
This power supply has 62A on the 12V rail and comes with a 5-year warranty. The semi-modular design is also a nice addition and will help anyone who wants to have really clean cable management. It also comes semi-modular and with a 5-year warranty. And, since Corsair typically has excellent customer support for their products, if something should go wrong, you can rest assure that they will take care of the problem. So, if you want to save even more money, you definitely can.
EVGA has pretty much dominated this list… and rightfully so as their SuperNOVA line of power supplies are well-made, extremely efficient, perform well, and are affordable for what they provide. At W it provides 45A on the 12V rail, which is plenty for just about any single card setup. They may cost a bit more, but higher certified power supplies tend to be more reliable than others. Luckily, most manufacturers offer warranties.
Reliability, customer support, warranty, and manufacturer reputations are among the first things you should look for when choosing the best power supplies. Since there isn't exactly a single solution that makes sense for every build, we decided on several categories to fit the needs of most PC gamers.
For each, we also took into account budgets, compatibility, unique features, and design. Our top selections were made based on a combination of the criteria listed above and overall efficiency ratings.
While it isn't by any means the all-telling solution for PSU performance, the 80 PLUS certification program provides some form of standardization and expectations for efficiency. More efficient PSUs mean less heat and lower energy consumption. It pays to future-proof against any upgrades further down the line. A modular PSU will allow you to add extra cables as needed or remove unused ones to free up valuable room inside your case.
This is handy if you've got your heart set on a beefier graphics card or want the flexibility of being able to add other peripheral connections later. However, you can absolutely make do without, as even semi-modular or fixed cable designs will do the job just as well if only with a few extra cables lying around.
You can usually tuck these into the back of your PC case to keep them out of your eyesight. As a word of warning, compatibility is a significant factor when it comes to power supply units. Even if they are from the same manufacturer, not all PSU cables will be universally compatible either, complicating things further.
If you absolutely must splinter from the cables included, have a look at your PSU's PIN connectors and make sure your cable set has ones that match to avoid any unnecessary frustration and breakages.
