Best 650W Power Supplies to Buy (ATX 2.0 & 3.0 Options)

Best 650W PSUs Feature Image

Introduction

With the exponential rise of powerful and pricey components over the last year, we’ve seen a huge increase in top-end high wattage power supplies. It seems the market has quite literally ‘gone mad with power’ with PSUs over 1000W popping up here and there in order to supplement some of the best graphics cards and CPUs we’ve seen in quite a long time.

But what if you’re not in the market to build an enthusiast level PC? For consumers looking to build something more mid-range or perhaps even budget, the need for a 1000W PSU is quite unlikely. At this level, the vast majority of users are looking at 650W or 750W to power their build, or even lower if you’re restricted by budget.

We’ve covered a number of 750W options in the past, so today we’re going to be delving into the best 650W power supplies to buy. We’ve covered a range of options from budget selections, all the way up to top-end ATX 3.0 designs geared towards the latest generation of graphics cards.

Suggested Article: Best 750W Power Supplies to Buy (Budget, Mid-Range & High-End Options)

Our Recommendations

1. MSI MAG A650BN

👑 The best budget PSU.

MSI MAG A650BN

Introduction

First off in our roundup is MSI‘s MAG A650BN power supply. This particular unit is one of the best options on the market for those on a much tighter budget. It is a little bit lacking on the features front, so additions like RGB, PCI-E 5.0 support, or even modularity don’t appear on this PSU, but this is ultimately to keep the price down.

There isn’t much to be said on the features front, consumers get access to a rather cheap option sporting an 80+ Bronze efficiency rating, alongside a low-noise fan. This PSU comes with all of the standard protection mechanisms to keep your components safe, and is super simple to install, as you don’t need to worry about choosing cables. We’d recommend this option to consumers looking to get into PC building for the first time, or for those that can’t quite afford the pricier but more feature rich options!

Things We Like

Don’t have to choose cables: Most consumers would argue that non-modularity is a bit of a loss. And it is on the cable management front, but if you’re a first-time build that would rather avoid choosing cables, the non modular design means you can plug in all of the cables that you need, and stuff away the ones that you don’t.

Low-noise fan: Picking out a PSU that whirs and buzzes as soon as the load reaches a certain level is frustrating. However, consumers won’t need to worry about this at all, as the A650BN features a 120mm low-noise fan that has specific sleeving and bearings to reduce any annoying extra noise.

Things We Don’t Like

Sports an 80+ Bronze efficiency rating: Although the efficiency of this PSU is better than nothing, if you’re the kind of consumer building a mid-range system with higher power consumption you can be losing a fair bit of power as heat, or noise due to the weaker efficiency.

Doesn’t do much for cable management: To argue the other side of the non-modular design, it really doesn’t aid consumers looking to build a PC with clean cables. You’re effectively forced to cram your cables into the PSU chamber or any channels due to the mess that comes with non-modular designs.

Summary

MSI’s MAG A650BN is the weakest power supply when it comes to features, and even efficiency, but as an oxymoron it has great value for money. If you’re a first-time builder that is just looking to pick up the cheapest option that will ‘do the job’ then the A650BN is a great choice. You may have to upgrade later down the line, but the strong warranty and solid price point makes this an excellent option for an entry level PC!

2. EVGA 650BQ Bronze

👑 The cheapest semi-modular PSU.

EVGA 650 BQ Bronze

Introduction

Next up is EVGA‘s 650 BQ which is a power supply that we’ve recommended a number of times in other roundups. Needless to say, the 650 BQ shares a similar story to the aforementioned A650BN from MSI, but this unit offers semi-modular cable support. What this effectively means is, your motherboard (24-pin) and CPU (8-Pin EPS) will built into the power supply, so you won’t be able to take them out of the unit.

For your peripheral and SATA connectors, you’ve got plenty of free reign when it comes to plugging in cables. If you’ve got a one or two connector GPU, you can plug in two to make cable management much easier, and this goes for any other devices you decide to install. The BQ Bronze also comes with a power on self-tester, which allows consumers to easily diagnose any issues with the power supply by conducting a jumper test. This ensure that the power supply works which is a nice add-on to come included.

Things We Like

Comes with a PSU self-tester: If you run into some issues with booting, or your power supply isn’t working as expected, you can attempt to diagnose the issue with the included self-tester. This jumper attachment connectors to the motherboard power, ensuring that the PSU turns on and hasn’t been fried.

Simpler cable management: Although this isn’t a fully modular unit, the addition of some modularity makes cable management much easier. Consumers can choose their cables for peripherals and other devices allowing you to zip up cables, or place them into various channels exactly how you want to!

Things We Don’t Like

Weaker efficiency rating: The 650 BQ from EVGA offers an 80+ Bronze efficiency rating. Whilst this will help when it comes to heat and noise levels, consumers pushing their PC a little bit harder will see more power lost as noise and heat.

Can be difficult to pick up at times: EVGA is renowned for creating excellent power supplies, and due to this, the demand can be quite high. This means that PSUs such as the 650 BQ Bronze can be particular difficult to pick up at times.

Summary

EVGA’s 650 BQ Bronze is another power supply with a reasonable price point that makes it ideal for consumers on a more restrictive budget. The support for some modularity allows users to install the majority of cables entirely as they choose, making cable management much easier. And the addition of a power on self-tester provides a way for consumers to diagnose their PSU if there are any problems.

How Do You Choose the Right Wattage?

As we’ve alluded to in the introduction, the increase in powerful graphics cards has caused a subsequent rise in the number of high wattage power supplies. Without knowing where to look, and what PSUs to pick out, a first-time builder might assume that 850W or 1000W is the modern standard required for a build today, but this simply isn’t the case.

CX650F Power Connectors - CX650F Review

The best way to get a rough idea of how many watts you’ll need, a good general guide, is to use your graphics card. AMD and NVIDIA will recommend a minimum power supply requirement in accordance with the total graphics card power, which gives you a rough estimate for power consumption. Your graphics card is normally the most power hungry component of the bunch, so this can act as a generalised guide on how many watts you’ll want to aim for.

Another solid way to figure out your wattage requirements is by using an online configurator. If you’re shopping for parts, you might have heard of PCPartPicker which is a website that we use all the time when fitting out builds to put together. Not only does PCPartPicker solve compatibility issues and show you prices, but it will also tell you what power supply to use too. For example, if you’ve picked out an RTX 4090, but you’ve opted for a 500W PSU, PartPicker will tell you instantly to pick a higher wattage option. There are other online configurators too, such as Cooler Master’s power supply calculator, which offers a similar experience, but just for PSUs.

There are a couple of factors to consider which might change your wattage requirements too. Upgradeability is the biggest one. If you plan on picking out some more powerful parts in the relatively near future, picking out a PSU with 100-200W more than your minimum is good practice, this just gives you plenty of space for higher-end components. Overclocking is another consideration too. If you plan on pushing your CPU past its rated clock speed, this means it will naturally consume more power, which could go above your total PSU wattage if you’re not careful. These factors are definitely worth considering before picking out your PSU.

Is 650W Enough for Modern Components?

As we start to look at lower wattage options there are more restrictions imposed when it comes to component options. Although many of the new components that we’ve seen in the past year or so are relatively power efficient, there is a line that needs to be drawn. Luckily 650W PSUs aren’t entirely at the budget end of the spectrum, but you might need to increase your wattage if you’re looking to build something at the top of the mid-range bracket, or perhaps a more enthusiast PC.

3050 + TD300 Mesh MWE 650 Gold

In terms of modern components there are a plethora of options available for consumers looking to build a mid-range or budget system. NVIDIA’s recently released RTX 4070 has a 650W minimum requirement, which is a solid graphics card for the price point, and perfect for a mid-range build. You’ll need to be careful about which CPU you pair up with this graphics card, as you don’t want to go above the rated wattage. On your CPU front Intel’s 13th-Gen range, such as the Core i5 or Core i7 options will also be perfect when paired up with a 650W PSU.

Although is guidance is a bit vague, and entirely depends on the components that you’ve picked out, I feel the vast majority of consumers have a plethora of component options if you’ve picked up a 650W PSU. You are primarily limited to the mid-range bracket, but this means you can build a 1440p or 4K capable gaming system, potentially with some legs in productivity applications. Just be aware that there are limitations in terms of component options, and going above your rated wattage can be dangerous and even damage your build.

Why You Can Trust Us

Before delving into the recommendations we wanted to clear up why you can trust our thoughts and the components that we pick out. Our team of PC hardware and gaming enthusiasts work hard to ensure all of the latest products we can our hands on are tested thoroughly and go through a full evaluation to see if the product is worth picking up at its given price point.

How We Picked the Best 650W Power Supplies

Power supplies are one of the many components that we get to test on a regular basis by putting them through the wringer in a variety of builds and benchmarks. As soon as we get a PSU through our doors we evaluate the unit’s specs, box contents, cable options, and design to get a well-rounded idea of what’s on offer. Then the PSU gets put into a PC build with similarly matched components to see how it performs. This gives us plenty of insight into installation, size, versatility, and just general usage, which allows us to ascertain pros and cons.

Once we’ve gathered enough information about the component, we then put together our verdict on the overall quality and value. All of our findings are then relayed to our audience through YouTube videos and written content in the form of buyers guides, or reviews. In this content, we attempt to provide a generalised overview of a product, and focus on how it might impact your gaming setup.

Frequently Asked Questions

RR Question Mark

Do I Need ATX 3.0 for My New GPU?

In short, none of the new GPUs on the market need ATX 3.0. All new NVIDIA GPUs come with an 8-Pin adapter which means you can still use your old power supply. However, for cable management perfectionists, picking up an ATX 3.0 PSU is worth considering.

RR Question Mark

What Kind of Components Can I Pair with a 650W PSU?

650W is more than enough for a modern mid-range system. Consumers will be able to pick up components such as Intel’s Core i5 13600K or Core i7 13700K. Graphics card wise, consumers will be able to pick up an RTX 4070 at the maximum, or an RX 6750 XT on the AMD side.

RR Question Mark

Is 80+ Efficiency Important?

Yes and no. It is important in the sense that your power supply should not be outputting an excess of heat and extra noise. But the 80+ rating, should not be your biggest deciding factor in picking up a PSU. We would recommend leaning more towards protection mechanisms and desirable features.

RR Question Mark

What is the Best Way to Determine How Many Watts I Need?

As a general rule, we tend to recommend PCPartPicker, or Cooler Master’s PSU calculator. These will give you recommendations of how many watts you need based on the components that you’ve picked out.
