Max Output: 1600 Watt | Efficiency: 80+ Titanium | Type: ATX | Warranty: 10 Year Warranty

Corsair is practically the epitome of perfection when it comes to PC building as it has long reigned over the gaming realm with its hardware. The AXi series is the top-tier PSU line from Corsair featuring the AX1600i which, as the name suggests, is a 1600 watt beast that can pretty much quench the need of any ultra power user. This kind of PSU is not used that often as it can devour more than 1600 watts from the wall socket but nonetheless, it’s definitely one to opt for if you are a power hungry enthusiast.

At the core, the fully modular build boasts 100% Japanese capacitors with 94% efficiency due to the 80+ Titanium certification. It is also the first enthusiast PSU to feature Totem-pole PFC Gallium Nitride (GaN) transistors instead of the traditional silicon parts for optimum efficiency and power management in a small form factor. These not only provide a more efficient and optimized power output but also ensure that the output is ultra-stable.

The Corsair Link software is another proprietary feature that promises power management, monitoring, and control along with the capability to navigate between operation modes such as the ability to alternate between single or multi-rail overcurrent protection (OCP). Some of the primary connectors include a 24 pin ATX connector along with an 8 pin PCIe and other peripheral ports.

The 140mm FDB fans pave the way for a much quieter and smoother experience even under heavy loads. Another significant cooling feature would be the functionality of a Zero RPM fan mode that minimizes fan speed when exposed to lighter tasks.

Corsair AX1600i stands tall among all of the other PSUs in this power range but the credibility and uncompromising quality of Corsair is more than enough to convince you.

2. CORSAIR RMX Series, RM850x

Our Rating: 8.5/10

  • Compact size
  • 135mm thermally controlled fan spins up as needed

Max Output: 850 Watt | Efficiency: 80+ Gold | Type: ATX12V / EPS12V | Warranty: 10 Year Warranty

Another Corsair feature but in a lower power range is the RMX850x with an 850-watt regulated output. This wattage is more economical and reliable for power users as it is a drastic downshift from the 1600 watt monster featured previously but can support most high end builds without breaking the bank. The size of the unit is subtly compact and weighs adequately as compared to its competition.

It features the same 100% Japanese capacitors with 80 plus gold certified efficiency, backed by the overall design. The 160mm length of the body ensures that this unit is compatible to fit inside most of the modern cases that you can come across today.

The installed cooling solution features a 135mm thermally controlled fan which is automated to spin as per the requirement and output. The fans are tuned to produce a low noise footprint even under high loads along with the conventional Zero RPM mode that Corsair offers to provide one of the most impressive and silent experiences that you can come across along with the precision built to max out the output while keeping the temperature at the server-grade of 50 degrees.

The connectors include the basic 1x ATX along with 2x ATX/EPS 12V, 6x SATA, 6x PCIe accompanied by some peripheral and floppy drive controllers. Whereas this might set up a gold standard among the most suitable PSUs for your power inclined needs while maintaining the wattage sanity.

Corsair RM850x clearly lists as one of the best 850 watt PSUs that you can come across today and it is definitely worth your time and money as Corsair give out a 10-year warranty with their PSUs to ensure customer satisfaction and quality deliverance.

3. Seasonic FOCUS Plus 750 Platinum SSR-750PX

Max Output: 750 Watt | Efficiency: 80+ Platinum | Type: ATX12V | Warranty: 10 Year Warranty

Seasonic Focus SSR-750PX is your best bet at stumbling across the best 750 watt PSU in this range. Even though Seasonic might not be that well renowned but still fares pretty well against its rivals that include models from Corsair and other big guns. There are numerous additional features that make this worthwhile and put it ahead of its competition.

A prominent feature to mention here would be the compact design with the 140mm depth that can easily manage its space inside most housings. It stands at a certified efficiency of 80 plus platinum which offers an output of 89% at 100% load. This would definitely save up a lot of energy in the long power run of your PC by feeding off significantly lesser from the socket.

Similarly, the connectors are gold plated and include 1x ATX, 2x CPU, 4x PCIe, 8x SATA, 3x Peripheral and a floppy drive controller respectively. All of this makes it an entirely diverse PSU to consider because it can easily power up a mini utility center while conserving resources. The cable-free connection design is where the back panel and the Printed Circuit Board (PCB) are connected via a copper plate instead of cables.

It also features a Hybrid Silent Fan Control that works around the principle of three regulation levels, fanless mode, silent mode, and cooling mode. The fanless mode is an intriguing concept where the fan does not kick in until the unit crosses 30% of its load capacity. And it also effectively generates enough output to power multi-GPUs without maxing out or overheating.

Seasonic SSR-750PX combines power with precision to make it one of the best mid-range units that can power your next setup to ensure a remarkable experience.

4. EVGA 500 B1

Our Rating: 7.5/10

Max Output: 500 Watt | Efficiency: 80+ Bronze | Type: ATX12V / EPS12V | Warranty: 3 Year Warranty

EVGA has been in the limelight for a while now with its exceptional range of products that are more directed towards the mid-range consumers. The 500 B1 is the ideal mid-range PSU that you can get under 500 watts. This power output is adequate enough to assure that your everyday tasks would never suffer along with some other plus points that you can attain with this unit such as powering a moderate GPU.

500 B1 is a non-modular form factor with a very minimalistic layout that features a compact design which can technically fit inside any case you would come across. It is proven to be very cost effective in terms of build quality and features an 80 plus bronze certification which translates into an overall 85% efficient output under typical loads.

Since it is a very budget friendly unit, EVGA definitely had to cut some costs and they accomplished so by not including the Japanese capacitors that can be usually found on other high-end comparable PSUs. 1x ATX, 1x EPS (CPU), 2x PCIe, 6x SATA, 3x Peripheral and 1x Floppy Drive are the conventional connectors that come with it.

The cooling system offers a very minimal setup as it is not a power-packed unit so it is less likely to be at the risk of overheating and the double ball bearing fans are optimized to function at near-silent levels. High amperage single rail establishes the room for a better more power efficient output along with a free power on self tester which might not turn out to be that effective but definitely worth a try.

EVGA 500 B1 is your one-stop destination if you are on the lookout for an economical yet featureful PSU as this would surely elevate your experience.
