10 Best Power Supplies For Gaming in 2020

If you’re going with a small form factor build, check out the EVGA SuperNOVA 550 GM. It’s a solid SFX form factor PSU featuring 80 Plus Gold certification. Its advertised 550 W output power should be more than enough for most Mini-ITX builds.

The price isn’t really budget-friendly but for an SFX power supply, the EVGA SuperNOVA 550 GM’s price is competitive. Small form Factor components are always selling for a premium and if you consider that fact, this is an excellent budget PSU.

The PSU features a semi-passive mode that will turn the fan down during light (up to 150 W) load. When under heavy load, the fan isn’t loud and reaches about 35 decibels. Do note that 35 decibels are reached very rarely. Only under extreme loads, like when running benchmarks that maximally strain the hardware.

Performance is pretty solid, especially if you consider the price. The PSU offers solid load regulation, just don’t expect miracles here. Efficiency, on the other hand, is pretty high. Overall, this is a pretty solid SFX form factor PSU that should be considered by anyone building a small form factor rig.

Corsair is known for its PC peripherals but the company also manufactures excellent PSUs. The Corsair RMX Series RM550x is an amazing power supply. In fact, if you don’t need anything more powerful this one’s the best power supply for a gaming PC you can get.

It features amazing performance, no matter how hard you push it. Efficiency is superb for an 80 Plus Gold PSU. This one is capable of trading blows even with 80 Plus Platinum models, which is a respect-worthy achievement. Load regulation is among the best in the class.

The Corsair RMX Series RM550x operates completely silent up to 250 W loads. Once the fan starts running expect the noise not to cross the 20 dBA limit, another excellent achievement. You can only hear clearly it under extreme loads, but that happens only during stress tests and not in real use.

Even the price isn’t too steep for what you get. Overall, if you need a regularly sized PSU in the 550 W category, look no further. The icing on the cake is the 10-year warranty offered by Corsair.

FPS is a known PSU manufacturer that builds power supplies for many different brands. Many PSUs featured in this piece use FSP design and components. FSP also manufactures power supplies under its own brand. The Dagger Pro 550 W is the company’s solution for Mini-ITX builds.

The PSU features 80 Plus Gold certification but it doesn’t offer excellent performance. Efficiency is solid under low load. But under normal and heavy loads, efficiency is low compared to the competition. Load regulation, on the other hand, is excellent.

Even though the FSP Dagger Pro 550 W boasts semi-passive mode, it is pretty loud. The fan can reach up to 40 decibels when under heavy load. And that’s under normal operation, not when running stress tests and benchmarks. Overall, this is an okay PSU but there are much better choices out there.

be quiet! is a company known for its silent PC cases and silent CPU fans. But be quiet! also makes quiet power supplies and be quiet! Pure Power 11 600W is one of the best in the company’s portfolio.

The PSU features the company’s signature black-with-orange-details design that’s pretty unique in the PSU market. It gives the be quiet! Pure Power 11 600W unique looks that set it above the competition.

Other than that, this PSU features semi-modular design and 80 Plus Gold Certification. Its main feature, the silent operation even under heavy load absolutely delivers. The PSU is quiet as a mouse until the load goes over 400 W. Under heavy load the fan reaches just 17 decibels, which is a superb result. The only scenario where it goes over 20 Dba is when running stress tests.

Efficiency is solid, it completely justifies the 80 Plus Gold stamp. Load regulation is satisfying but it could be better. Performance could also be better, but it’s far from bad. Also, a 5-year warranty is okay but competitors offer longer warranty periods. Overall, be quiet! Pure Power 11 600W is the best silent power supply you can get right now for a price that won’t break the bank.

EVGA Supernova 650 G5 is a solid 650 W PSU that features 80 Plus Gold certification. The PSU looks nice. As is the case with the be quiet! Pure Power 11 600W, this one also features brightly colored fan cover.

When it comes to performance, this PSU is a solid competitor but not the best in the class. The semi-passive mode makes the PSU completely silent up until 20 percent load. From there, the fan turns on and it can become really loud when under heavy load. Under 80 percent load expect 35 to 40 decibels, which is a steep noise level for a power supply.

Efficiency is very good and completely justifies the rating. Load regulation is tight, one of the best in the class. The PSU handles variable loads – usual scenario in real-world usage – really bad. Overall, this is an okay PSU for the money but it suffers from low overall performance and a really noisy fan. At least EVGA offers a 10-year warranty, which is always nice to have.

The Cooler Master MasterWatt 650 is an affordable PSU for those who need a reliable Power supply for a low price. This power supply has 80 Plus Bronze certification. Low price point also means semi-modular design and uninteresting design. Cooler Master offers a 5-year warranty with this PSU, which is okay for a budget model.

When it comes to efficiency, this PSU shows excellent efficiency for its 80 Plus Bronze rating. The semi-passive mode works for loads up to 15 percent.

The PSU if fitted with low-grade capacitors, which could become an issue in the long run. Load regulation is good for the price, just know that higher-priced models can deliver much tighter load regulation. Overall, this is an excellent budget PSU that should be powerful enough for almost any configuration.

This PSU features 80 Plus Platinum certification and its performance and efficiency are on par with the rating. In other words, both are brilliant. Its max load surpasses the rated specs by 82 W so you can be sure it will run like a charm even under extreme loads.

The semi-passive fan mode doesn’t really work, but that doesn’t matter. Yes, fans are spinning even under light load but they are practically silent until the load reaches about 450 W. Under heavy loads fans stay below the 35-decibel limit, which is a solid result for an 850 W PSU.
