Overview

The best power supply (PSU) ensures that your components receive consistent, clean energy. They'll complete this duty effectively, saving you from wasting a ton of energy while playing. Because of the increasing power requirements of CPUs and GPUs, modern gaming systems require robust PSUs, which is why it's more crucial than ever to choose the best PSU for your system.

Overly inexpensive PSUs aren't worth it. Thus we focused on models you should spend a bit more money on to feel secure. But don't consider that money wasted. The best power supplies are more effective, operate without a hitch, and may be reused in subsequent constructions. This does not imply that all of the PSUs we suggest are pricey. They're not; some of our favorite PSUs cost only $50. A cheap PSU differs significantly from a reputable company and one from somewhere else.

Don't worry about going overboard either; high-capacity PSUs used to be less effective at lighter loads, but this is no longer the case. Of its capacity, if you choose a contemporary Gold or higher, it will be effective at lighter loads (which is good). With its most recent ATX PSU specification (v2.53), Intel has imposed specific low-load efficiency standards, with the bar currently at 70% efficiency and 10W (500W capacity), or 2% of its maximum rated capacity loads.

Along with low-efficiency requirements, Intel's most recent specification also addresses PSU timing issues related to Alternative Sleep Mode (ASM), enabling the system's quick wake-up from sleep mode. ASM uses Microsoft's Modern Standby as an illustration. Although there are currently no motherboards that are ASM-compatible, remember that PSUs can last you for years, so you'll be prepared for when ASM does get popular.

Don't worry if you're still unsure where to begin regarding a power supply; we've evaluated dozens of PSUs and selected our favorites, indicating the kinds of builds they belong to.

1. Corsair RM750x (2021)

Product’s Specifications

  • Manufacturer (OEM): CWT

  • Max. DC output: 750W

  • Efficiency: 80 PLUS Gold

  • Form factor: ATX12V v2.4, EPS 2.92

  • Noise: Cybenetics A- (25-30dBA)

  • Cooling: 140mm Mag Lev fan (NR140ML)

  • Modularity: Fully modular

  • EPS connectors: 2

  • PCIe connectors: 4 (on two cables)

  • Warranty: 10 years

Product’s Highlights

The famous RMx line of power supplies from Corsair needs to undergo some revisions now that the competition in this market category has become much more fierce thanks to products like Seasonic Focus GX, XPG Core Reactor, Super Flower Leadex V, etc.

Since the RMx units in use today only had a three-year production run and offered excellent performance and virtually silent operation, the process is not simple. It's normal for things to go wrong when you try to improve something already good, but happily, this is not the case with the new Corsair RMx line.

Five models in the new Corsair RMx (2021) range are available, with power outputs ranging from 550W to 1000W. The following are the main variations from the earlier models:

  • Increased lifespan using a magnetic levitation fan when operating at high temperatures

  • Modern standby compatibility for high-speed wake from sleep times

  • high performance with light and high light loads

  • Three EPS connectors with 850W and 1000W power supply units

  • Certificates - 80 PLUS Gold

The new RM750x outperforms the older model in terms of performance but at the expense of the older model's near-silent operation in terms of average noise production. Although the new model's average noise output is close to 28dBA and receives a Cybernetics A- rating, you cannot classify it as loud.

The fan upgrade is a very nice feature, to sum up. It increases dependability even in challenging environments where most gun and fluid dynamic bearing fans eventually experience problems. With two EPS and four PCIe ports on two cables, this PSU can support a GeForce RTX 3080 in a strong gaming system.

Pros

  • High overall performance.

  • Two EPS and four PCIe connectors.

  • Highly efficient at light loads.

  • 10-year warranty.

Cons

  • In cable caps.

2. Seasonic Prime Titanium TX-1000

Product’s Specifications

  • Manufacturer (OEM): Seasonic

  • Max. DC output: 1000W

  • Efficiency: 80 PLUS Titanium

  • Form factor: ATX12V v2.4, EPS 2.92

  • Noise: Cybenetics A- (25-30dBA)

  • Cooling: 135 mm FDB Fan (HA13525M12F-Z)

  • Modularity: Fully modular

  • EPS connectors: 2

  • PCIe connectors: 6 (all on dedicated cables)

  • Warranty: 12 years

Product’s Highlights

With its Prime platform, which starts at Gold efficiency and goes up to Titanium, Seasonic struck gold. Several well-known companies, like Asus with its ROG Thor 1200W, Corsair with its AX line, and Antec with its illustrious Signature line, have previously utilized Seasonic's foundation technology in their own PSUs.

Even though they are expensive, if Seasonic could produce more of these units, I would anticipate more brands lining up to source them. Unfortunately, the bulk of customers favors less expensive, low-efficiency power supply. Still, you can be sure that a product is infallible when an OEM is self-assured enough to offer a platform with a 12-year warranty.

The Seasonic TX-1000 power supply has excellent build quality and is a superb product. It uses Japanese capacitors everywhere, including several polymer caps in addition to electrolytic ones, excellent soldering, and a fluid dynamic bearing fan.

The engineers at Seasonic made every effort to provide incredibly high efficiency in all load zones, silent operation, and increased reliability. Performance-wise, this PSU is in the top division because of its excellent ripple suppression, tight load management on all rails without needing obtrusive in-line caps, and lengthy hold-up times. Additionally, the PSU gets some of the highest efficiency readings we have observed so far at light loads, and the 5VSB rail has high efficiency.

The TX-1000 includes six PCIe connectors on dedicated cables, which is an additional benefit. Energy-hungry graphics cards can be powered without a problem, even though using a single cable with two PCIe connectors is recommended.

Pros

  • High overall performance.

  • Quiet operation.

  • High-class build quality.

  • Fully modular.

  • 12-year warranty.

Cons

  • OCP at 5VSB.

3. Corsair CX450

Product’s Specifications

  • Manufacturer (OEM): CWT or Great Wall

  • Max. DC output: 450W

  • Efficiency: 80 PLUS Bronze

  • Form factor: ATX12V v2.4, EPS 2.92

  • Noise: Cybenetics A- (25-30dBA - CWT) | Standard+ (35-40dBA - Great Wall)

  • Cooling: 120mm rifle bearing fan (HA1225M12F-Z [CWT] or D12SM-12 [Great Wall])

  • Modularity: No

  • EPS connectors: 1

  • PCIe connectors: 1

  • Warranty: 5 years

Product’s Highlights

The CX450 is the cheapest model in Corsair's low-cost CX range. The two OEMs that produce the CX models, Great Wall and Channel Well Technology (CWT), employ different platforms to produce the various CX models.

Their RPS numbers, reference designators assigned to each model, are the only method to distinguish them from one another. Fixed wires are used in both designs to keep costs as low as possible. However, they use contemporary platforms with voltage control modules and LLC resonant converters to provide high-quality fans and minor rails.

Such a cutting-edge platform at this pricing range is uncommon. The strangest thing about the Corsair CXM units is that they employ a lower-performance platform despite having semi-modular cables that give the impression they belong to a better category.

Great Wall's version of the Corsair CX450 is more effective than CWT's, especially under light loads, and it features a more effective 5VSB rail. However, because of its more aggressive fan profile, it produces more excellent noise.

Pros

  • Modern platform.

  • Rifle bearing fan.

  • Low price.

  • Five-year warranty.

Cons

  • Non-modular

4.  Corsair AX1600i

Product’s Specifications

  • Manufacturer (OEM): Flextronics

  • Max. DC output: 1600W

  • Efficiency: 80 PLUS Titanium

  • Form factor: ATX12V v2.4, EPS 2.92

  • Noise: Cybenetics A (20-25dBA)

  • Cooling: 140 mm Fluid Dynamic Bearing Fan (NR140P)

  • Modularity: Fully modular

  • EPS connectors: 2

  • PCIe connectors: 10 (on eight cables)

  • Warranty: 10 years

Product’s Highlights

Few other desktop PSUs utilize the cutting-edge power supply technology initially introduced by the Corsair AX1600i, even years after it was first introduced. In essence, the AX1600i combines a totem-pole PFC converter with GaN MOSFETs, allowing it to achieve up to 99% efficiency compared to the most sophisticated conventional APFC converters that can only achieve 96% efficiency. Okay, so those are the technical specifics. You need to know that this power supply is about as efficient as they get.

The AX1600i manages its circuits using two Digital Signal Controllers (DSCs) in addition to the totem-pole PFC. The communication link between the system and the power supply unit (PSU) is a single microcontroller (MCU), which enables users to perform other operations outside monitoring chores like controlling the fan speed profile and choosing between multiple and single +12V rails.

The AX1600i duly succeeds the illustrious AX1500i. Due to Flextronics' use of cutting-edge technology and its digital platform, both units deliver the best performance currently available for purchase. The AX1600i has high efficiency, excellent load control, superb transient response, a lengthy hold-up time, and excellent ripple suppression.

Despite its high capacity, it remains impressively quiet in operation, thanks to the relaxed fan profile and a high-quality FDB fan. Finally, using the Corsair Link software, you're able to choose between three fan modes: performance, balanced, and quiet, so every user will be able to set the PSU according to their needs. You will pay a lot to get your hands on a Corsair AX1600i, but there is nothing else able to meet this PSU eye-to-eye when it comes to overall performance.

Pros

  • Full power at 48°C.

  • Powerful performance.

  • High build quality.

  • Quiet operation.

  • Fully modular.

  • Software control.

  • Amount of connectors.

Cons

  • Expensive.
