Power supply units are one of the most underrated components in a gaming PC setup. This is largely due to gamers misunderstanding their usefulness.

However, PSUs can prove to be vital for your PC’s reliability, durability and performance, the three pillars of your gaming experience. Hence, it becomes paramount to choose the best power supply for gaming.

There are a lot of things to keep in mind before opting for computer hardware like a power supply. The first step any gamer should do before buying one is to know their PC in and out. It is then that they will be able to know their requirements.

So, jump into the next section after learning about your PC configuration.


What Are Power Supply Units?

All PSUs are basically used to convert the current from your power outlet before they reach the computer. The outlet current is usually alternating in nature and is not useable by your PC. Hence, a power supply unit is essential for operations.

The converted direct current is supplied to essential components like motherboards, graphics cards, speakers etc. They cannot work in tandem without a power supply unit. Moreover, PSUs also come in handy when the computer overheats or there is voltage fluctuation.

How Power Supply Units Work?

Now that we have seen the importance of having a great power supply unit, let’s see how they work. This vital component is usually found in the form of a metal box placed in a corner of your CPU. It is easily recognisable from the outside as it is connected to the power cord and contains a cooling fan.

PSUs are also called switching power supplies because they use a switcher mechanism to convert AC to DC voltage. The common voltages needed in a PC are 3.3 volts, 5 volts and 12 volts.

Furthermore, the 12 volt supply is used for bigger components like motors and fans while the smaller ones are used for circuits.

Modern power supply units are advanced and as you would know, the whole system can be turned off by using a menu button in the software.

Additionally, there is a standby 5 volt circuit in place which is usually connected to the power button in the CPU. This is in place to let you switch on the power supply and in turn start the whole computer.

A typical power supply unit has small transformers, transistors, cylindrical capacitors and aluminium heat sinks. The transistors take care of the switching while the heat sinks absorb excess heat. Diodes are attached on the sides, which are responsible for converting AC to DC.

Technology has come a long way since computers were first invented and has enabled the best gaming PSU to be a fraction of the size they once were.

The current is usually supplied at 60 Hz and PSUs convert it into a bigger frequency. This allows a miniscule transformer to step down the 220 volt AC input into smaller individual DC voltages.

Factors To Consider While Buying A Power Supply For Gaming

1. Wattage

The first thing you should look for in the specification sheet of a PSU is wattage. Basically, wattage indicates the combined amount of watts that particular power supply can deliver to various internal components. The minimum wattage of a PSU is 300 while some higher end ones come with a staggering 1600 watt capacity.

A potential buyer should always keep in mind that bigger is not always better in the case of gaming PSUs. Although, most gaming PC setups need a lot of wattage, it’s better to check your individual requirements using this online tool.

It really would be beneficial if you don’t spend a ton of money on something you really don’t require.

After getting the exact value of wattage needed, round it off to the bigger near value and look for a PSU with that number. If you plan on adding or upgrading components in the near future, it’s better to buy one with 100-200 watts more than what is recommended.

One important thing to note while looking for wattage on the label is to inspect whether it is continuous wattage or peak wattage. The latter doesn’t tell the complete story. Consider a PSU with a wattage of 500. In the case of peak wattage, the 500 watts are delivered when the demand is maximum for a few minutes.

However, you will find that a continuous wattage PSU will be able to deliver those 500 watts for a prolonged period of time. So, it goes without saying that the best PSU for gaming will come with continuous wattage.

2. Power Efficiency

Now, who wouldn’t want a power supply unit that consumes less power and saves you big bucks on your electricity bill? That’s why prior research to find out the efficiency of a PSU is vital. Moreover, an efficient power supply will also be cool and quiet when throttled.

As we know by now, PSUs convert AC to DC, so that individual components get the correct voltage. During this conversion process, energy will obviously get wasted. Some power supply units waste more energy while some don’t. Consequently, the latter is said to be more efficient than the other.

Thankfully, independent certifiers have created a rating based system that evaluates the efficiency of power supply units. The best gaming power supply will have an 80 plus titanium rating.

That is the gold standard as far as efficiency is considered. However, anything with an efficiency of 80 plus is considered good enough.

3. Rails

The rails are paths through which power flows to the independent components in a PC. Generally, there are two types of rails in a PSU. One is single-rail and the other is multi-rail. As the name indicates, a single rail PSU doesn’t divide the voltage and supplies the full value to a particular component.

However, in multi-rail PSU, voltage is divided into two or more parts. This is usually done by using many connectors and cables. Thus, the single rail system will be able to provide the full power to every component.

On the other hand, the risk is also higher because in case of voltage fluctuation, it will shoot too much current to the components in one go.

This makes the two rail system safe and secure. However, power sharing between two rails can’t occur. If there is a mismatch between maximum amp rating and required amps, overcurrent protection will occur and shut down the system.

So, be aware of your requirements and choose between single rail and multi-rail carefully.

4. Connectors

Connectors and cables are one such factor that do not require too much attention. However, it’s better to be safe than sorry. If you are in the market for a very high end and specialised PSU, you should be fine with the standard.

20+4 is the most used connector configuration. It means that 4 pins are separate and can be used according to your needs.

High end PSUs are special in terms of connectors as they use something called as modular cabling. This allows the end user to fit custom cables and connectors. This is highly beneficial when you need to upgrade your gaming PC by attaching many custom parts to your rig.

5. AT And ATX

PSU’s are generally made for two types of motherboards, that is, AT type and ATX type. Sometimes, you can find Power supplies made for both types, but this is very rare.

Most PC’s these days have ATX motherboards and hence require the same kind of PSU. However, it’s better to check the details of the type of motherboard your PC has and then proceed.

6. Brand

The best Power supply for gaming is usually made by the best and most renowned brands in this niche. If you buy a PSU from less reputed brands, you run the risk of using a product that is made from substandard parts.

Moreover, such brands usually overstate the specifications and features to make the product look good.

Longevity is also a massive issue and should never be compromised on. If you buy a power supply from a reputed brand, it will easily last you till your next PC upgrade or even more than that if wattage requirement of both is the same.

Some of the well known brands are Corsair, Antec and Seasonic.

Additionally, it is also automatic in nature, meaning it gets turned on by itself when the temperature increases or it senses a heavy load. This is definitely one of its better features.

Inside the box you will find a 20+4 main connector pin and a single 4 pin. It does miss out on having both 6+2 or 4+4 pins. This is definitely one of its major drawbacks.

Apevia has also given it 5% tolerance against 5V, 3.3V and 12V outputs. This is also quite familiar in this price range.

Since the power supply unit is using a single rail mechanism, the manufacturer has provided it with protection against common electrical hazards like short circuits, over voltage, under voltage, over temperature etc.

This however doesn’t cover every type of hazard like the PSUs from bigger brands.

Additionally, the weight seems to be quite low at just 2.65 pounds. Even for a 450 watt PSU, this seems low.


17. Letang Raidmax Cobra

Letang Raidmax CobraLetang might not be a very famous brand in terms of power supply units, but this product from the manufacturer is one of the highest rated PSUs in its price bracket.

It boasts of class leading specifications and a very funky looking design suited for gaming PC’s. What else has it got to offer? Let’s find out in the next section.

The power output wattage of the Raidmax Cobra is 700 watts. This is unparalleled at this price point. You can also find 700 watt PSUs for twice or thrice this price.

The efficiency is also class leading as it is rated at 80 plus bronze. This means that at normal load, it can give an efficiency percentage of 85%.

The combination of good power output and great efficiency means that this power supply can punch well above its weight and give competitors a run for their money.

Although the company has not specified the size of the fan being used, users have reported that it’s big enough and can handle all the heat that is produced under peak load. It is also quite by nature and the noise won’t distract you.

Letang has not been able to provide semi or full modularity in this product. However, we should not consider it a drawback at this price point. Moreover, since there isn’t any heating issue or tough installation, modularity wouldn’t have made a big difference.

The system uses a single rail design and Letang has its vulnerability covered by making it resistant to short circuits, over power, over and under volt. It has also provided all connectors necessary like the 20+4, 6+2, 4+4 etc.

Last but not the least, the weight is around 4.2 pounds, typical of most 700 watt power supply units. All of this makes it the best power supply for gaming at this price point.


18. Evga 500BT

Evga 500BTWe have reviewed a long list of EVGA products in this article and the last one is from the lower end of its spectrum. Although it’s specifications might be at a lower level than the similar priced Letang Raidmax Cobra, the EVGA brand name and reliability make it a viable option.

Unlike other EVGA power supplies, it doesn’t have a list of unique features that sets it apart from others but offers good value for money.

It has an output wattage of 500 which is good enough for a mid-range gaming rig. The efficiency is also quite good as it has an 80 plus bronze rating.

This combination will suffice for most gamers. The fan diameter is around 120 mm, this is typical for 500 watt power supplies.

Like most other EVGA products, the product users have not reported any issues in reliability or longevity. Also, the fan is quiet and the system remains relatively cool under intense loads.


19. Coolmax I500

Coolmax I500Coolmax is one of the brands that makes very affordable power supply units. Most of its products occupy the lower price categories. Hence, it is in direct competition with Apevia.

The consumers have received the I500 with good reviews. Also, the specifications offered by the power supply unit is more than enough for the price tag.

The power output from this unit is around 500 watts. This is more than enough for a mid level gaming PC but other features like efficiency and temperature control will not be suitable for it.

One thing that does disappoint is that even though the PSU has a single rail design, the company hasn’t provided protection against under voltage and over temperature.


20. Coolmax 240 Power Supply

Coolmax 240 Power SupplyThe Coolmax 240 is the lowest priced power supply unit on this list. It is very similar to its bigger brother, the I500. The only difference you would be able to spot is in the power output.

The form factor is very basic and doesn’t consist of braided cables, modularity, all black wires etc.

The 400 watt output will be enough to power the most basic gaming rigs. However, it doesn’t have very good efficiency or an automated fan. This might make it obsolete in the coming years.

Also, the company has provided just a 20+4 and single 4 pin. All this makes us recommend this product only for the entry level gaming rigs.

Frequently Asked Questions

1. What is a good power supply wattage for gaming

It’s a frequent occurrence that many gamers overestimate their power supply needs and buy large PSUs that are overkill for their gaming rig. This is usually done on the pretense of being on the safer side or for future upgrades. However, this can lead to more power consumption, reduced efficiency in the long run, increased build cost and operation cost etc.

So, to make it more clear to gamers reading this, here is a general rule of thumb. If you use a beginner level gaming rig, then a power supply unit of 300-450 watts output is more than enough. If you use a mid-range gaming PC then you would need anywhere from 450-650 watts of output from your PSU. However, if you do use a very high-end gaming PC, then too you would not have an output wattage of more than 900 watts.

2. How Long Would My PSU Last?

Like with any other product, it totally depends on the quality of the components used. Assuming that very good quality internals are being used, it would be fair to expect a lifespan of 5-6 years. However,if the warranty of the power supply unit is more than that, it will last as long as the warranty period.

To make sure that you get the best longevity, don’t subject your PSU to loads that it can’t handle. Also, before buying, it’s better to buy from a reputed brand and make sure the internals are of great quality.
