Tier-S Best Power Supply for Gaming PC in 2020

best power supply for gaming pc

With each passing day, there’s something new in the stash for gamers; especially, GPUs and CPUs. A dream gaming pc includes probably everything groomed and latest and brings in a seamless gaming experience. To be honest, a power supply is an integral part of your system, let’s say a magical ward that protects your PC from voltage spikes and fluctuations. The same power supply also provides ample power to your gaming pc with a withstanding efficiency. But this concept is restricted and tucked in the box because no one takes it seriously. A bad power supply can ultimately lead to your gaming system’s downfall: an immediate death warrant. Well, that’s the reason why we will be discussing the best power supply for gaming pc.

I still remember lodging in a Redragon’s local PSU in my gaming system. After a couple of months, my whole system was in Dante’s inferno. Like there was a weird trail of smoke billowing out of my system, and suddenly everything went black. Then I did some research and came to a conclusive end that, as long as your PSU is from a notable brand, you are in safe hands. This story is just a small piece of a larger puzzle, where each day, hundreds of gaming systems experience a serene death. If you do not want that to happen to your beloved and shining gaming system, follow these upcoming steps.

How to choose the best power supply for gaming pc?

The foremost step is to cherry-pick a power supply that fulfills all the added ratings of your component. Let’s say your CPU, GPU, motherboard adds up to 450W. For future-proofing your PSU, you would need around a PSU of 500W or higher. If you go with a rating that just matches the threshold (read: boundary) rating, then the chances of your system dying is an all-time high. Maybe, your system won’t even turn on. To counter this problem, you can use online power supply calculators for the addition of individual ratings and know about the recommended PSU for your system.

Now comes the need for selecting the best possible rating for your power supply. Well, considering the international rating system, you get to cherry-pick from:

  1. 80 Plus
  2. Bronze
  3. Silver
  4. Gold
  5. Platinum
  6. Titanium

Let me remind you, these ratings are not fundamental ratings that you can get; since the gaming horizons are ever-expanding. But for the sake of simplicity, we’ll go with these. After choosing the best power supply brand, it becomes imperative for you to select one of these ratings. The 80 Plus rating represents the overall efficiency of your PSU at 80% or above. The titanium rating is the best in the list since it ensures that around 87%-90% of the power generated is supplied to your components. In plain terms, less power is dissipated as heat. Well, the efficiency is also measured in discrete levels: 20%, 50%, 70%, 80% and 100% loads.

It’s worth mentioning that as long as the efficiency of your PSU is high, the heat generated in your components will also remain at bay. On top of that, you need to consider individual brands and what sort of customer service they pitch in because I have come across a couple of crappy Cooler master supplies that have negligible reliability.

Editor’s pick

Corsair AX1600i (Editor’s pick)

Corsair AX1600i

I’ll be honest with you! I deliberately substituted a humungous power supply in the list that goes up to 1600W. Well, it’s indeed an overkill, but have you heard of the Nvidia’s announcement about the RTX 3000 series? In the reveal, the graph showed that the RTX 3090 would, collectively with other components, require at least a 1200W rated PSU. Some enthusiasts will buy the latest GPU; hence, the reason for pitching in Corsair AX1600i is the editor’s pick in the list. The power supply is fully modular, which means not only will it power on your motherboard, but also other components like fans, coolers, peripherals, and a lot more. Not to mention, the PSU is 80+ Titanium, which means that the power generated will be used up by 94%. Only 6% will be lost as heat.

To be honest, it’s a huge difference marginally when compared with bronze and standard-rated PSU, where the loss as heat goes up to 16%. On top of that, it’s recommended to use the PSU on an ATX build because of its size. In addition to that, the PSU makes use of gallium nitride transistors for enhanced efficiency. The included fan is also designed to run at low-noise levels, which means although you will be running an RTX GPU, the overall noise produced will remain at bay.

Pros
  • Can turn on beasts components
  • Fully modular with external connectivity
  • Uses Titanium rating
Cons
  • Extremely expensive
  • Huge

After Corsair and Cooler Master, Antec is one of the reputable brands for PSU. If, by chance, you don’t get your hands on either of the first two, then Antec should be your resort. Well, Antec HCP-1300 is a 1300 watt power supply with a Platinum rating. The rating allows the PSU to produce higher efficiency rates; for example, with platinum rated PSU, you can go up as high as 90%, which is an amazing score. 90% percent efficiency means that only 10% is lost as heat. Not to mention, Antec HCP makes use of high currents, which means that the resistance in the wire remains at bay. On top of that, the PSU is full time modular, which means that you can plug in any device as long as they have connectors for a 24-pin slot, 

4+4 pin slot, 8-pin slot, Molex, SATA, floppy, and OC link.

The PSU’s overall size is decent, which means that you can slot it easily in standard ATX cases. Do you know what’s surprising about Antec HCP? You can use the OC-link given at the back to connect two Antec PSUs. This ultimately leads to collective added power from two PSUs. For example, you can get a 2600W supply with two Antec HCP-1300, which is truly withstanding. You also get to hold a 7-year warranty, which is enough to sustain the product’s credibility.

Corsair RMX RM1000X

Corsair RMX RM1000X is a wonderful and working PSU. Well, 1000 rated PSU are generally enough to turn on your RTX and Core i9 builds, but you need to up your rating game for something bigger than that. The Corsair RMX RM1000X is an 80+ Gold rated PSU, which means the PSU’s overall efficiency is above 80%. It’s a little disappointing to see that the efficiency is directly related to the amount of load on your PSU, which means that the overall efficiency will be different on 20%, 30%, 50%, 70%, and 100%. So, do keep that in mind before purchasing the PSU. Not to mention, the transistors in the PSU can withstand the temperatures up to 105 degrees Celsius, which is commendable, in my opinion.

It’s worth mentioning that the fan uses zero RPM mode, which means that the noise levels will remain at bay. Other than that, you can use modular DC cables to extend the overall load on your PSU.

Cooler Master MWE

I know that people will call me a fool for inserting a cooler master power supply. To be honest, the hate is discouraging because, at times, units can be turned out to be faulty. There are a couple of Cooler masters units that are crappy and faulty; that’s the reason why people do not buy the cooler master’s PSU that often. But believe me, this one is different because I have personally used it for like four years before changing to corsair. The PSU is 80+ Gold rated, which means that the efficiency levels pitched in by the PSU is time high.
