Best PSU For Ryzen 7 3700x Reviewed

Budget Pick

EVGA 500 W1

Best Power supply For 3700x Budget Pick


Brand: EVGA | Output:500 Watts | Weight: 4 lbs | Dimensions: 5.51 x 5.91 x 3.35 inches

If you are running a 3700x, the EVGA 500 W1 is the best budget PSU for your 3700x. I understand building a PC on a budget is not a piece of cake; you must think about everything carefully.

Choosing the product is much simpler because every PSU EVGA produces 80+ energy efficiency. The price and warranty length are closely related; if you want a PSU from EVGA with a 10-year warranty, be prepared to pay more (the same is true with other matures, for obvious reasons.)

I like how the installation process was straightforward. All praise to the Labeling they have done for various parts. Because of this labeling, I had an easy time connecting every cable without any hassle.

Make a list of your connectors and confirm that the supply has a connector for each one. There are plenty of connectors in this supply, so you probably won’t need more than what they offer.

This power supply has a huge fan that automatically regulates speed, so it is quiet when operating under light to moderate load. It can become noisy under many loads, but not more so than any other 80+ supply I’ve used. On the back of this supply is an off switch.


Solid performance

Pocket friendly

Plenty of power

Quiet operation


Looks might bother build enthusiasts

Low amperage


Overall, If you are running low on budget and need a quick Power supply for your 3700x, then the EVGA 500 W1 is all good. However, the odd-colored labels and low amperage might not be something good for build enthusiasts, but it works well at this price point. I am all up for this!


Best Power Supply For 3700x High End


Brand:NZXT | Output:500 Watts | Weight: 4 lbs | Dimensions: 5.9 x 5.9 x 3.39 inches

NZXT is a company that makes gaming hardware and is well-known for creating powerful and efficient computer cases. The E500 Power Supply is one of the best mid-range power supplies for the Ryzen 7 3700x.

What I like the most is that the manufacturers have claimed that the internals are made of Seasonic. I often struggle to find PC components that are not too pricey or cheap because you must be lucky to stumble upon a pick that is in the mid-range category and still performs the best.

I didn’t like how the installation part was a bit flimsy for me. In my case, getting this PSU and its cables was a hassle. I didn’t like how the cables were cheaply made like I am paying a premium price and the cables are still flimsy. After a hard work of 2 hours, I put this PSU into use.

I absolutely loved that this PSU came with added DSP and CAM support. I utilized the software to look at the fan curve, temperatures, and profiles. I am happy how Seasonic has worked with NZXT to create a masterpiece.

Now comes the test that we all wait for, which is the noise test. So the PSU was running all okay and didn’t have any noise when the PC was idle. However, under load, this PSU got so loud that it was unbearable for me.


Solid power supply

Added CAM support

Fully modular

Comes with DSP


Flimsy cables

Turns loud under heavy load


The NZXT E500 is good because it has a simple setup along with a solid power supply. However, remember this one gets a bit loud when running under high load, but if you are okay with that, this provides a solid performance.

Best Pick

EVGA SuperNOVA P2 650

Best Value Power Supply For 3700x


Brand: EVGA | Output: 650 Watt | Weight: 6 lbs | Dimensions: 6.5 x 5.91 x 3.4 inches

The EVGA SuperNOVA P2 650 is one of the best value PSUs for 3700x. It is an excellent option that is well designed and can handle even the most demanding gaming machines.

I never support overspending on computer parts, but when it comes to power supplies, I think you get what you pay for. And because the EVGA Supernova is the best premium PSU for the 3080 for this reason, I would advise you guys to buy it if you have some extra cash saved up.

Okay, let’s start with how it appears overall. The PSU has a black matt finish, which I initially found to be kind of appealing. Additionally, I think the construction is stout and will hold up for me for a long time.

The length of the cables was the next aspect I adored. Since this PSU is completely modular, the included cables are absurdly long. And from what I can tell, they can run as long as your PC case does. But some users might not have enough space to accommodate such long cables, which could be a drawback.

Having said that, even though the cables are long, the main PSU cable isn’t as long as I would have liked. For example, setting up the entire setup to the power source was difficult, and that part was a bit hectic.

Additionally, I don’t believe any of you would need to go out and buy cables separately because it comes with a ton of cables. Furthermore, I liked how the cables were arranged in a wrapped mesh.

Furthermore, everyone had access to labels for all the cables, so I doubt anyone would have trouble organizing them. I set up the entire setup in about two hours, and the fit and finish could not have been better.

I then tried using this one in several tests. To see if it reports any failures or not, I first tried gaming over this one. Surprisingly, there was absolutely nothing to complain about.

Also, there were no odd noises made during the operation. Power supplies typically make a lot of noise, but this one was quiet even when operating at full capacity.

There were only two minor issues with this power supply that I could find fault with. One thing is that the power source cable and cord could have been made a little bit longer and of higher quality by the manufacturers.

I can get the same performance with the Corsair RM750x, so why should I spend an additional $100 on this, you guys. Like I should have a good reason for spending an additional $100 on this power supply.


Very quiet

Decent cable length

Easy to install

Lots of power


High profile

Short AC cable adapter


The EVGA 220-P2 is good only if you have enough space to accommodate it. It is not that huge. Yet I believe dimensions might be a bit taller for some PC cases. So, before you order one, do have a proper measurement of your PC case.

Staff Pick

Seasonic Prime PX-1000

Best Power Supply Editor’s Pick


Brand: Seasonic | Output: 1000 Watts | Weight: 6.6 lbs | Dimensions: 6.7 x 6 x 3.4 inches

The Seasonic® Prime PX-1000 is the ultimate power supply in the best power supply category. Seasonic Prime Px-1000 is one of the best power supplies for the Ryzen 7 3700x editor’s choice.

Its superior efficiency, high-quality components, and industry-leading modularity make it a worthy choice for even the most demanding users. This powerful unit is engineered with exceptional efficiency to maximize performance and ensure an outstanding return on investment.

With its advanced, fully modular design, the Prime PX-1000 allows users to expand their system into future upgrades as needs arise. The Prime Series provides an innovative, high-quality upgrade that is easy to install, extremely reliable, and features the highest quality components on the market today.

There is not much to talk about the aesthetics here because they are all simple and back, as Seasonic always does. They do not value visuals but ensure the best performance possible.

Installation was quick and simple. I had no issue putting this one up in my PC case. And I guess this is all due to the modularity of the cables. This also made the cables remain sturdy and organized. And a plus point here was that it came with cable ties, so I had a very easy time winding everything up.

Now, as we are talking about the cables, let me tell you some drawbacks. First, the cable sleeves aren’t something I actually liked. It was made of a flimsy material which annoyed me. Also, the cable length was short. Thank god I had another PC case I could get with that.

Additionally, I loved how the PSU remained quiet. Even under load, I had nothing to worry about noise. But guys, when I had this PSU under extreme load, it made some weird fighter jet noises which was a huge turn-off. But then again, guys, the performance is premium. I don’t mind compromising over the noise part.


Easy to install

Decent modularity

Plenty of cables included

Tons of wattage


Short cables

A bit noisy under load


The Seasonic Prime PX-1000 is a good choice for those who want a powerful power supply with decent wattage. I found the cable length a bit short, but that isn’t much hard to adjust. Also, the noise level was pretty high under extreme load, but the performance was worth the hassle!

CORSAIR RMX RM750x Power Supply

Best No Noise Power Supply For Ryzen 7 3700x


Brand: Corsair | Output: 750 Watt | Weight: 3.6 lbs | Dimensions: ‎6.3 x 5.91 x 3.39 inches

Many of the readers complained to me about their PSU making a lot of noise. So I thought, why not give you guys a PSU that is one of the best no-noise PSUs for the Ryzen 7 3700x.

I’ll start by mentioning the incredibly sturdy construction of this one. Additionally, I was happy to discover it was on sale because the performance is worth much more than $90!

I liked the all-black construction because my PC case is black overall, and I was looking for a black PSU, so this fit the bill. While I don’t believe everyone needs to make aesthetic changes, my PC case was clear, so I preferred its black presence.

The installation process came next, and unlike my previous PSU, this one had very clear instructions for connecting cables. Can you believe that every cable arrived with labels and that I had no trouble organizing them?

The built-in cables were also fantastic because SATA cables had multiple connectors, which made chaining easier for me. I had been looking for this in various PSUs for years, but I couldn’t find it.

The testing phase was currently the most crucial. I tested it by rendering videos and playing games, and the PSU continued to function without any reported crashes. Everyone detests it when their PSU fails while gaming, but with this particular one, I really enjoyed myself.

I tested the noise component last but not least. Guys, I am not purchasing another PSU that makes a noise similar to a fighter jet. To cut a long story short, this PSU’s noise level was extremely low. Although it isn’t completely silent, the noise didn’t bother you.

You guys must be wondering what this power supply’s drawbacks are. So, besides the cost, this power supply doesn’t seem to have any drawbacks. Even so, the cost is reasonable because it serves as a power source, and I don’t believe we should cut corners here. However, some of my colleagues might consider this a high-end PSU.


Works well with overclocked 3700x

Completely modular

Runs quiet

Highly efficient power supply


A bit pricey


The Corsair RMX series RM750x is a wonderful powerful supply with up to 75o wattage. However, the price is a bit high but you can expect to pay this for a powerful power supply.

Cooler Master MasterWatt 750

Best Mid-Range Power Supply For Ryzen 7 3700x


Brand: Cooler Master | Output: 750 Watt | Weight: 4.4 lbs | Dimensions: 5.51 x 5.9 x 3.38 inches

If you have just $80 in your pocket, then the Cooler Master MasterWatt 750 is the only PSU you need to go for. This mid-range power supply covers the needs of those who just want to make the most out of their Ryzen 7 3700x and get the most out of their hard drive.

This PSU performs well under pressure. There is no issue gaming or performing demanding computing tasks, but I specifically looked for this item because I wanted a silent PC build.

The PSU makes an abrupt Swirling sound when the PC begins to work while it is idle. Throughout the day, this incident occurs repeatedly. Incredibly annoying. According to some Reddit forums that I’ve read, there is no way to avoid it. This is much worse than some low humming, in my opinion.

It is a good power supply unit to power your computer; it is important to note that it is a medium-performance power supply unit that successfully feeds your computer as long as you calculate the energy-intensive components.

Although it is made of high-quality materials, the cable is very thick and makes it difficult to move around inside the cabinet, especially for models with 24 pins for the mother and 4+4 pins for the processor (CPU).

It is unquestionably a good power supply, but take care—even if you have extra power—I do not advise using it to aggressively overclock your CPU or GPU. Under heavy load, this PSU can get extremely hot and can even burn out.


Quiet operation

Semi modular

Delivers decent power

Easy to install


It might get hot at times

Not for overclocking systems


The Cooler Master MasterWatt is a decent PSU of mid-range price. It has a lot of praiseworthy features. But remember, it might get hot at times. A good cooler along this PSU will do that.

Thermaltake Smart RGB

Best Good Looking PSU For Ryzen 7 3700x RGB


Brand: Thermaltake | Output: 500 Watts | Weight: 3.3 lbs | Dimensions: 5.9 x 5.5 x 3.3 inches

If you have a compact PC case with little space, you don’t have to worry about anything. This is one of the most common issues many of my readers report, so I will introduce you to the best compact PSU for Ryzen 7 3700x, the Thermaltake Tough Power GF1.

For systems with 3700x, it has an astounding 80-plus gold efficiency rating, which is more than enough. And because it is one of the most energy-efficient PSUs available, I was genuinely pleased with the final result.

The label won’t be upside down if you top mount it because the logo is on one side backwards, making installation easy. Long and of decent quality, the cables. It has three 8-pin connectors for those installing GPUs requiring three power connections.

However, I encountered some issues when attempting to unplug the 24-pin connector of the motherboard from the power source. I eventually came up with a workaround, but if I had to disconnect it, it probably wouldn’t have been possible.

It is beautifully packaged, very quiet, and entirely modular. It comes with a top-notch bag for keeping extra cables. I must admit that the quality of the bag really impressed me. It proves that they gave quality a high priority when designing this product.

This power supply seems to have sufficient response time and accuracy to maintain component satisfaction. I found that overclocking still had issues and wasn’t completely trouble-free. Since then, the system has never hung or had any other odd issues.

It has a clean, minimalist cable design, which I found appealing. There are as many cables included that are designed to fit into the ports on this PSU. The ASUS Toughpower GF1 stands out from many other PSUs on the market thanks to Smart Zero Fan.

This particular fan can only operate when the load exceeds 30%. Sounds fantastic! Fortunately, this causes the PSU to operate quietly without making any unnecessary noises. Unfortunately, after about 8 hours of intense gaming, the PSU started running a little hot and made strange noises.


Super silent

Stable power supply

Affordable pick

Decent cable organization


Heats under load

Messy cable organization


I cannot think of a single drawback for this PSU. Its modularity, potent performance, and small size make it ideal. It is, therefore, the best 3080 compact PSU. There were some issues with the cable organization, but everything was fine. Guys, remember that this one can get a little hot when under a heavy load.


Without a Power supply unit, your system will be a blank box. As a Ryzen 3700x is a powerful and robust system, it needs a specified kind of PSU equipped along it. Hopefully, I have provided enough Power supply units for you in this article.

You can choose any pick available according to your PC build and requirements. If you are still unsure, let me share my favorite ones:
