The P2 variants are presently the second most popular ones that are manufactured by EVGA’s with T2 still being their number one product. 

Its line comes with a total of six different PSUs with 650W and it goes as high as up to 1600W. This includes all mid as well as high-level categories. 

As of now, nearly every P2 model fulfills the criteria needed for the 80 plus rating. It offers a flexible cabling system that one can easily adjust as per his system needs. 

Apart from that, it gives you a semi-automated functionality, and the option to customize it completely in case you want the fans to work longer.  


The PSU works through DC and DC converters. It is designed to run for long hours with 50C temperature and is backed by the ATX.  

Coming to the main highlights of this unit, for protection, the OC here is changed by OPP.  However, one of the main drawbacks is the unavailability of an OTP. It is an essential feature in the majority of power supply units that are semi-automated. 

Moving on, this model is also equipped with a dual cooling fan. Considering all the core specifications and features so far, especially the dual cooling fans, they hardly make any noise when your system is turned on. 

Moreover, the overall size isn’t too big either, however, it is slightly expensive than other mainstream PSUs available in the market.

2. Corsair RM550x – Psu for ryzen 7 3700x

Corsair RMX Series (2018), RM550x, 550 Watt, 80+ Gold Certified, Fully...
  • 80 Plus Gold certified for lower power consumption, less noise and cooler...
  • Tuned for low noise operation even at full load
  • Zero RPM fan mode for near silent operation at low to medium loads


This model is probably one of the less demanding power supply units from Corsair. The maximum range for power is 550W and it scores a perfect 80 PLUS Gold rating. Moreover, it comes with a complete modular cable system, and it gives you a powerful performance without being too loud and noisy. 


Earlier, Corsair revamped its RM range by releasing more power-oriented power units that were equipped with a complete digital user interface. This helps users to easily keep a track of all core statistics to handle the fan. 

But now, it seems that creating a more budget-friendly model is the maker’s topmost priority. Therefore, you don’t get any fancy interfaces or circuits in this unit. 

This line features a total of five winning models that are ranked among the best PSUs for ryzen 7 3700x. 

Its power ranges between 550W and goes as far as 1kW. Since this is an elementary level unit, the features are selective but useful. All units under this line feature CWT with Gold efficiency. 

Its design is a modular one and therefore, no cables or wires are permanently attached to the device. 


The fan won’t run if the workloads don’t reach up a certain level. Here, Japanese capacitors are used as the primary ones. Moreover, these capacitors are used in nearly all variants of this unit.  

They help to keep your system more safe and secure. And without it, you cannot experience the level of performance that’s associated with the best power supply for Ryzen 7 3700x. Moreover, it makes the unit last longer too. 

If you opt for power supply units with Chinese capacitors, they won’t give you the same performance as a Japanese capacitor would give. 

Chinese ones work on less powerful electrolytes and therefore, it makes the system age more quickly. And if you are using it in more extreme temperatures, then it is bound to age even more quickly. 

And therefore, more premium ones such as Japanese caps are recommended for power supply units. 


Nearly all minor rails provided are powerful enough to work with 550W units effortlessly. And you can use all kinds of graphic cards no matter how powerful they are. 

The connectors are good enough for running a 550W power supply unit. However, it would have been better if it provided more connectors. 

This unit supports Haswell architecture and OCP with one 12V rail. The fan itself is powerful enough to last for years without any replacements. The dimensions are perfect to fit inside any system. Overall, the body is lightweight and portable. 
  • Compact design
  • Easy to set-up

As of now, the mainstream power supply units from Corsair and EVGA are ruling the market as affordable power supply units. 

However, what experts believe is that newer power supply units are the future choice for gamers and miners. 

With this model, Phanteks has worked on the lines of Seasonic for building a more contemporary power supply model.

So far, the makers have kept three different variants under this range of power supply units. The power ranges between 550W and 750W. And the best part is that all three variants share the latest Gold platform of Seasonic. 

Apart from that, it can easily withstand high temperatures without any noticeable difference in the performance of the unit. 


Coming to the features and specs of this power supply unit, nearly all units are equipped with a set of EPS connectors. 

Earlier, almost every budget-friendly power supply unit that came with a power of 500w or less featured a single EPS only. 

Thanks to constant development and research by the makers, you get a total of two connectors in this model. However, bear in mind that each connector has a maximum capacity of 336W instead of 500W.

Apart from that, with this power supply unit, you get a set of 6+2 connectors that provide power up to 150W. 

And therefore, it can easily work with more advanced models and run with more demanding motherboards which require more power for processing. 

The cables are long and of the right length. Plus, you get a good amount of connectors that run perfectly with this power supply unit. The only thing that the makers could have improved is the space between Molex connectors. 


Nearly all models featured in this line, follow Seasonic’s Plus Gold format.  Moving on to the design and built quality of this unit, it is lightweight and has smaller dimensions. 

It is compact yet sturdy enough to withstand extreme temperatures. Some users may find the limited space affects the airflow or ventilation in the unit. The air filter comes with two separate components. 

Every single component that has been used in this unit is of premium quality and it comes with a brand warranty.

The efficient fan profile is what makes it a strong contender for the best power supply for Ryzen 7 3700x. Besides the seamless performance, the power consumption options are further customized, with constant current protection.

Nearly all PSUs created by NZXT, are premium ones where the makers invest an adequate amount of time in coming up with intricate and long-lasting systems. 

Since NZXT is one such brand that is known for manufacturing commercial power supplies, and now that it has stepped into making PSUs, then you best believe, that you are getting world-class performance at a competitive price. 


The unit that we will be reviewing this time is its C650 variant which is a popular model of the E series. Overall, it offers a more quick, secure, and responsive performance. 

Coming to the system configurations, what you get is three different variants with 850W being the highest power supply. It gives you enough power to run your system seamlessly. 

However, you don’t get any 1000W variants which you get to see in other popular PSUs. For nearly all gaming set-ups, the 500W model works perfectly well. 

Apart from that, this model too is customizable. It comes with plenty of options to tweak up the default system settings. And the best part is, it comes with a long brand warranty. 

You can easily use it for over years. Moreover, it comes with multi-rail OCP with 4+4 pin connectors. 


When building a gaming rig from scratch, picking the best PSU for Ryzen is crucial otherwise you won’t be able to create an efficient gaming system. 

For the past few years, with PSUs becoming quite expensive, it becomes crucial that you pick the right one as per your gaming needs. 

It also comes with a separate carry pouch to hold all necessary wires and cables. 

Apart from that, you also get a USB header to connect your PSU with the motherboard. 

Although, this feature isn’t necessary it does help users to keep a track of their system at all times. 


The availability of OCP is there for 12V connectors. The system does make sounds that are loud and may disturb you a bit. 

However, the overall performance is something that doesn’t disappoint you especially for games that require an adequate amount of power supply to all components of your gaming system. 

This model comes in a pure matte finish. There is no flashy design that you get to see in the majority of PSUs. The overall appearance of this PSU is sharp and minimalistic. It isn’t too heavy or bulky and has a more compact and lightweight body.

Thermaltake has been coming up with some powerful PSUs in recent times. And with Thermaltake Smart RGB 500w, it has certainly come up with a more commercial power supply unit.  


For starters, this unit features a sturdy chassis alongside an efficient cooling system. With 500w, it covers the majority of PCs used in pro gaming. 

It is a more budget-friendly non-modular model. It is a great option for new gamers looking for affordable power supplies to build their gaming rig. 

The RGB lighting works perfectly well with any gaming setup. However, apart from the fancy exterior of this power unit, it has a lot more to offer in terms of its internal components. 


This unit comes with an 80-plus rating but isn’t a standard bronze-rated. Apart from that, it features one +12V rail. 

Since this isn’t a modular unit, nearly all essential wires are pre-attached where you cannot change or modify them. 

Still, what you get is a good mix of different cables. However, we still suggest considering the specs and the recommended power supply for Ryzen 7 3700x beforehand, especially if you are using a modular unit. 


There are a total of ten different LED lights that lights up the entire unit. So far, this is one of the few power supply units that come with RGB lights. 

Apart from that, you also get cooling fans with over 12 different lighting modes. 

This model is available in 500W and 700W capacities which also happens to be the recommended power supply for RTX 2070. All RGB lights are completely customizable. It comes with over 12 different patterns and 200+ colors. 

This unit supports more conventional processors and isn’t too demanding in terms of its power needs. Despite being a powerful power supply unit, it doesn’t cost a lot.

This is yet another powerful PSU for Ryzen 7 3700x from EVGA. The brand is synonymous with making budget-friendly PSUs with SuperNOVA being its most popular unit so far. 


All in all, you get a good model at an affordable price but the makers haven’t compromised on the features or specs of this PSU. 

However, unlike other units, we have covered so far, this one does not have a modular interface. It comes with an 80 PLUS Bronze rating. Apart from that, it does not weigh a lot and has a sleek design. 


Coming to the main specifications of this PSU, this model is also Haswell ready. Although, many users are still skeptical about the exact guidelines for it.

Also, it will mostly attract its core audience which includes other providers alongside engineers. Apart from that, it comes with all the essential protections that you get in mainstream PSUs.  

The cooling fans installed perform seamlessly. However, you don’t get a semi-automated option here. 

The brand warranty isn’t too short and just like other PSUs mentioned in the list, it comes with a 10-year brand warranty. 

Since, the makers claim it to work for 10 years, then you best believe that the system will perform exceptionally well without even any minor lags or malfunctions. 


The 12V rail is powerful enough to run the system where the secondary ones are ideal for mid-range ones.  

Coming to the wired connections of this model, all wires are long and durable where you get a single EPS alongside a set of PCIe connectors. 

Apart from that, you also get SATA connectors. The energy distribution, however, is debatable as it comes with only one 12V rail. 

Just like other models offered by EVGA, it comes in a plain matte body which you get to see in nearly all SuperNOVA PSUs. Apart from that, its casing also has an 80 Plus badge on the front.

This unit works exceptionally well and is designed for those who are looking for a budget-friendly power supply for their new gaming set-up.

After featuring its iconic Titanium and Platinum line of PSUs, these are Seasonic’s updated variants which means you get more power and portability for a similar price. 


Firstly, what you notice in the updated models is a more compact design with the main units with lesser capacity ranging between 550W and 750W. 

Apart from that, what you get is a more convenient set up of cables, making it easier for those who are working with such cables for the very first time. 

Moreover, the basic SATA connector is 3.3 and backs the Power Disable feature. Moreover, you also get a separate tester to power up the unit in case you don’t want to do it with the help of a motherboard. 


Among all the upgrades this model comes with, the best one so far are the fans. It doesn’t make any sounds as the fans run quietly. 

Therefore, it is quite apparent that Seasonic is using the reduced fan levels to make the unit more efficient and responsive. 

Moreover, if the filtering caps were placed internally, it would have been better. Moreover, it would not overheat easily. 

Apart from that, one of the most prominent changes is the modification of the SATA connectors. Firstly, it is SATA 3.3, therefore, you get better SATA support. 

Moreover, it allows users to control the overall power consumption. It is designed to work at 40C and scores a rating of 80%. 


With more and more consumers coming into online crypto conversion, many PSU brands have started to give extra attention to the temperature control of the power supply. While the majority of power supply units offer a standard 10-year warranty, this one gives you 12 years of full warranty support.

With this unit, you can keep a track of the monitor temperatures, control it and simulate the fan curve, based on the option you have opted for.

  • 550W Power Capacity with Powerful Single +12V Rail
  • 80 PLUS Bronze Efficiency
  • 120mm Smart Hydraulic Bearing Fan


Nearly all variants available in these series come with powerful features which makes it a perfect option for those who need an efficient, powerful, and budget-friendly power supply unit for their system. 


Coming to the main features of this unit, firstly unlike other units mentioned above, you cannot disable it. 

Even if you try disabling it then it might be possible that you will end up losing some core features of the system. 

Here, you are also getting a standard 12 Volt rail with 54A. Apart from that, this unit features a solid 80 PLUS rating and holds Bronze certification. 

For PSU protection, you get over power protection, over-voltage protection, under-voltage protection, and short circuit protection. 

As mentioned earlier, since Seasonic is one of the leading providers of budget power supply units, you get premium quality components at a competitive price tag. 

And what you get is a seamless and steady output in a conventional unit.


Those who are looking for an affordable power supply to build their system from scratch can consider investing in this unit. 

The only downside is the sound it makes while it’s working. Those who don’t mind the overwhelming sound can consider investing in this unit. 

Overall, the unit works exceptionally well for the price you are paying for. You get a stable performance throughout where the 50% load for 500w is more than enough for building an efficient gaming rig. 

Apart from that, the warranty period isn’t much when compared with other power supply units mentioned in the list. It has 5-year warranty support which is quite short as all mainstream units come with at least 10 years of warranty. 

Apart from that, you also get options for conversion of SATA. However, for doing so, you will need to invest in extra converters separately. 


This power supply unit is hands down, a multifunctional one. And plenty of options for customization are there, thanks to the modular design. 

The only disappointment is the fans which is probably the only downside of this unit. Apart from that, another downside of this power supply is the limited number of SATA connectors for both HDD and SDD. 

Overall, it is a simple unit to set up, owing to the proper placement of cables. The body has just the right dimensions and will easily fit in all types of systems. 

The body is neither too big nor too small. It comes in a minimalistic design and those who don’t want too many flashy lights in their gaming setup can consider investing in this multifunctional power supply unit.

  • Multiple options for PSU protection
