Corsair HX 1000i

Our top pick for powering your system is the Corsair HX 1000i. While you could opt for a unit with higher wattage, 1000 watts covers a massive range of devices with plenty of breathing room. We highly doubt that your gaming PC is going to need more than 1000 watts.

This PSU's build quality is top notch and the power efficiency is fantastic. This fully modular PSU also features Corsair Link technology, which can be used to monitor and control the PSU from within your OS very accurately.

Ultimately if you want a high performing PSU that is relatively quiet then this PSU is for you as it's relaxed fan profile keeps noise to a minimum and if this ever malfunctioned don't worry it features a 7-year warranty.


EVGA SuperNOVA 850 (P2 Series)

This 850W PSU from EVGA gives you excellent power with value to boot when you compare it to some of the competition. This PSU has platinum certified efficiency ensuring less power being wasted, lower temps, and a happier system.

The full modularity makes this a great PSU to build with and will allow for some tidy cable management. The build quality as we have come to expect from EVGA is top notch and this PSU features a lengthy warranty should it ever break down.

There is a notable downside to this PSU and that is the price, the higher you climb with efficiency, wattage, and build quality the higher your price. Despite the price, this PSU offers a lot of power and should see most high-end builds through for years but it also adds extra power for those looking to overclock and upgrade their systems in the coming future.

This is a great PSU just make sure it isn't overkill for your system first!


EVGA SuperNOVA 650 (G2 Series)

This 650w PSU from EVGA is a brilliant mid-tier PSU and it is good enough for any of our featured builds. This would supply higher end builds with enough power but it would reach its limitations nearer the very top. Aside from its impressive wattage for the price, it is also certified gold for efficiency. Bronze is an acceptable level but this gold level offers up to 92% efficiency which will lead to less heat being generated and circulated around your system.

This has more than enough power to satisfy most and is a perfect fit for the mid-range builders. It's fully modular too so you can easily tuck away those cables once it's installed and we highly recommend it to anyone!



EVGA SuperNOVA 550 G2, 80+ GOLD

This model from EVGA like the others in the G2 range features silent operation. This PSU is seriously quiet for a 550w and its largely down to being super efficient. The PSU operates in a passive mode until called upon combined with a low-speed fan which adds up to very little noise.

This PSU offers consumers excellent performance and it does it for less than some major competitors too! This is the perfect PSU to power your mid-range system and features fully modular cables for easier building and better airflow. This gold certified PSU also comes with a lengthy 7-year warranty (not that it will break) and for the price is virtually unbeatable.


Corsair CX450M

Our budget option is marginally more expensive than some of our competitor's picks but makes a huge change to the building experience by going Semi-Modular. In addition to being Semi-Modular, the overall build quality seems to be much higher on this PSU than some of its rivals.

The primary benefit that Semi-Modular offers over a Non-Modular solution is that most of the cables can be removed. The only exception is the motherboard power cable, which will permanently be plugged in anyway.

Since you’ll only be connecting the cables you need, your cable management and building process should be much easier. Good cable management allows good airflow, preventing long-term cooling issues within your PC.

Additionally, the 450w may be the lowest of the recommendations, but it’s more than suitable for entry-level PCs, as well as most mid-tier ones.

We’ll cover how to calculate your wattage needs down below, but know that this PSU is a solid option.

Selection Criteria


First and foremost, you need to address the wattage concerns of your PC.

Using the PSU Calculator, you should understand what your power needs are pretty quickly. If you find that the PSU you would like only just meets those power needs, we recommend buying one with a higher wattage to make sure there is no bottlenecking and you have something for future upgrades.

What many people find, however, is that PSU wattage needs for their system are lower than what they think. Run this tool before making a purchase!


Modularity primarily affects the building process and airflow. In short, it has no bearing on your PC gaming experience when you aren’t tampering with your PC.

Semi and Full Modular systems are significantly more convenient. As mentioned it also improves airflow and this is down to not have several cables you are not using clogging up the empty space inside the case. We highly recommend that you opt for a Semi or Full-Modular PSU regardless of your budget.

Efficiency Rating And Meaning

Efficiency rating determines how effective your PSU is at managing power. The higher the efficiency, the less power consumed and the less excess heat generated.


Last but not least is the manufacturer. We’ve put in the groundwork to ensure that all the PSU's on this list come from reputable manufacturers in the industry: Corsair and EVGA.

Some other trustworthy manufacturers include Cooler Master, Seasonic, and Rosewill.

Once you’ve found your wattage needs and ran through this section, you should be ready to make your choice.
