Best 400 – 600W Power Supplies

If you are building a low or medium end gaming rig, then this range of power supplies are best suitable for your computer system, and this is preferred by most of the newbie gamers.

Even if you have installed high-quality video card just like RX 580 or GTX 1070, then also an efficient stable 550W power supply will do just fine for your gaming system.

So, my advice to you is to not go with high power supplies unless you are building an extreme gaming rig containing high-end graphics card and next-generation CPUs.

1) EVGA SuperNOVA 550 G3 Power Supply

EVGA SuperNOVA 550 G3 Power Supply
EVGA SuperNOVA 550 G3 Power Supply

 

The first one on the list is EVGA SuperNOVA 550 G3 Power supply. These G3 Series power supply offers the next generation performance and features with the smaller size only a 150mm long making them some of the smallest type of power supply in the market today.

In addition to that, a new hydraulic dynamic bearing fan offers better and quieter operations with an increased lifespan.

It comes along with EVG ECO mode giving you almost no noise in low or medium load. The design of this power supply already take the efficiency of G2 Series model and make it even better with improved power efficiency and low ripple.

This power supply has over 80 PLUS Gold rated efficiency with modular design and comes up with the award-winning warranty of 7 years and 10 years.

If you are more likely to do overclocking, then I would suggest going with a little bit higher quality and more expensive PSU as this one does fluctuate at higher clocks.

Without a doubt, the EVGA SuperNOVA 550 G3 power supply is not only suitable but also the best power supply for gaming pc in the market.

Pros
  • 5.9” deep smaller chassis
  • 80 PLUS Gold certified
  • 7-year warranty

Seasonic G Series 550-Watt SLI Ready Power Supply
Seasonic G Series 550-Watt SLI Ready Power Supply

 

Something to know guys before I move on to the detailed review, Seasonic is an actual manufacturer, most of the power supplies you buy are manufactured by someone other than the label on the front of the box.

On the other hand, Seasonic designs, manufacture, package then sell the power supplies you are buying from them. So by any chance, you make up your mind buying this Seasonic power supply for your gaming pc, then you already know they are the real manufacturer of it.

Seasonic G Series comes with 80 Plus Gold Certification which means the power supply can provide 87% efficient at 20% load, 90% efficient at 50% load, and 87% efficient at 100% load.

This is a semi-modular power supply which means that the connectors everyone needs, every time they build the system are hardwired whereas the connectors that are not required to be fixed every time while building the system are not connected by default.

It has DC to DC converter design that gives you almost full access of the output power supply because what the DC to DC design doing is actually taking the 12V and down converting it to other voltages.

It also offers smart and silent fan control to maintain the proper cooling of the components which I really expect from Seasonic, as they were the one who pioneer the feature on the back of the power supply where you can turn the fan off for the 50% load on their 80 PLUS Platinum 1000 watt unit, unfortunately, that feature is not available in this model, but you can still enjoy the proper cooling with the smart inbuilt attached fan.

How to Pick the Right Power Supply for Your Gaming PC

When it comes to power supply there is so much amount of Spec information and general information available in the market. In this Buying guide, I am going to talk more about the generalized side of how to buy the top power supply for gaming PC.

Wattage Power

How to pick the correct wattage power supply? this is the tricky question especially for the first time builders who might be not familiar with how power hungry some of their components in the computer system are. Once you chose the correct wattage power supply for your system after that the rest of the tasks of building a gaming rig relatively gets simpler.

So without further ado, let’s talk about power consumption and how to select a better power supply.

There is a common misconception in the market that power supplies are based solely on TDPs (Thermal Design Power), no doubt this is a good way of having a rough idea about how much power your system needs, but it’s not an assured thing.

Let say if you have a CPU of TDP 91 watts, it doesn’t mean it only consumes 91W. In fact, if you might overclock the CPU, it might consume 150 Watts.

So you can understand how TDP and total power consumption are somewhat proportional, as you increase the total power draw, the heat output must increase, but there is a small margin of losses are there as nothing is 100% efficient.

So, in summary, adding TDP is actually an underestimation of total power draw which actually not make sense. So here are some general things to know for deciding the best wattage power for your system.

Firstly, you need to know that there are two most power hungry components in your PC is Graphics card and your CPU. So when it comes to picking the PSU, you want to refer to these first, and then adding other things also such as gaming load, editing load, and torture load.

Depending on what you do, your power consumptions will vary. If you play video games on a daily basis, you are probably pouring more power than you are adding on a daily basis. Usually, video editing and graphics editing will leverage your amount of power supply needed, but in gaming, the use of graphics card and CPU is almost 50-60%, so you require more optimization of power supply in those conditions.

After gaming load, we have torture load in which the actual efficiency of the system is checked. The torture load is the maximum unrealistic workloads applied to the CPU/GPU to ensure that under the worst case scenario those components will be stable at given frequencies and voltages.

So a gaming workload is a pretty much safe estimation of what is the wattage of your power supply should be, but I also recommend choosing the power supply higher than the torture load.

So there is a right way to determine how much power your build will pull from the power supply under any workload. Use a watt meter take up the difference between the output and the power supply and boom that is how much power your system point under any given load. Keep in mind that some of the power will get lost in the inefficiency of the power supply itself, somewhere in between 80 & 90% of that is used by the system.

Modular Design

Reading through the entire article, you stumble upon the word fully modular power supply and semi-modular power supply. Actually, it is an important aspect to choose the best power supply.

In earlier days the cables from the power supply were just coming out from all the places, it can be seen as an octopus, but jokes apart, that bunch of cable wires is hard to manage which cause the clutter inside the entire power supply and the chases as well.

But the modern day power supplies adopted the Modular and the semi-modular design, the Modular design is the one in which all the cables are not hard-wired, you can use only those cables that you need while creating your gaming rig, and on the other hand, in semi-modular design, there are a number of wires that you don’t  plug or unplug on a daily basis are hard-wired and rest are by default free.

Benefits of a Good Power Supply

Having a good power supply will give you many benefits, including:

Prevents damage to PC: Having a top quality PSU will protect your internal components of PC from shorting out and thus provide an increased lifespan of all the internal hardware components.

Cutoff electricity bill: A high-efficiency power supply can reduce your electricity bill, which can make a significant impact if you are a serious gamer.

Provides Future Compatibility: If you decide to upgrade your PC in near future, or you would like to overclock your PC, in that case, you won’t have to buy a powerful PSU to provide to provide the stable power supply.
