Best 650W PSU

Do you also belong to the clan that never prioritizes the power supply unit as CPU and motherboard? If yes, then right now, you might have no idea what to buy because a PSU was the last thing you thought about while looking for a PC. Let me tell you one thing. Buying a high-end PC is useless if you do not invest the same time and money in buying the PSU. Mostly the power supply units are neglected and bought at the end when the budget is tight. Many people buy whatever they find without doing any research. Such products are often low in quality and reduce the life of your CPU. A power supply unit is as critical as a CPU. So, you need to be very careful while buying it. Just keep in mind, your CPU deserves the best power supply unit and most likely the one with a higher wattage.

Higher wattage hurts nobody, and it is always a good decision to buy upgraded PSUs. So, the best 650w PSU will be a great option. And if you are looking for 500w or 600w, then I would recommend a 650w PSU because experts say that you buy a higher PSU than the one required. A 650W PSU has shown 90% efficiency under testing, so it is a big yes for me. When buying a PC, you expect amazing performance from it, and let me break this to you. The performance of your PC solely depends on the PSU. So, think out of the box and go for a higher wattage PSU. Below I have compiled a list of the best 650W PSU, so you do not have to do a lot of research. Let us begin!

Corsair CXM 650W

Best Budget 650w PSU


Brand: Corsair | Form Factor: ATX | Output Wattage: 650W | Efficiency Rating: 80 Plus Bronze | Modularity: Semi-Modular


Amazing built

Neat cable system with no hassle

Easy installation


May face voltage issues at SATA port

Corsair is widely used and trusted by the tech community out there. This brand has been very consistent in the past years with the quality of its products. It has always improved features and performance. Second, on the list is our cheapest option the Corsair CXM 650W which is the best budget 650W PSU. It is from the CX series, which will amaze you with the specifications of its models. Especially the 650W CXM, which comes with a 4th Generation Intel Core processor.

Many consumers out there think that they do not need an 80 plus certified PSU. That is incorrect. To have an 80 plus certification in any category should be the bare minimum for you to look for. Having at least 80% efficiency is the lowest you should be going for. Efficiency below this is not worth it. The CXM 650W holds the 80 Plus Bronze rating. It will deliver an efficiency of 80% to 85% at loads of 20%, 50%, and 100% making it the best 650w 80 bronze psu.

This reduces the overall cost of the product and makes it a great “value for money” option. With efficiency as high as 80%, only a small 20% is dissipated as heat. This means that there are meager chances of the system getting heated up due to excess heat. That is amazing. With this one, you get the flexibility of modular cabling, and it is very under-rated freedom, to be honest. The modular cabling involves a reduced number of cables to make the system hassle-free for you. Now you only must bear the cables you need, nothing extra.

Corsair TX650M Gold

Best Gaming 650w PSU


Brand: Corsair | Form Factor: ATX | Output Wattage: 650W | Efficiency Rating: 80 Plus Gold | Modularity: Semi-Modular


Operates professionally even at high temperature

Includes high-quality capacitors

Marked connectors

Longer reliability


A bit higher noise level

Corsair TX650M Gold is bound to impress you with its stellar performance and amazing features. It is a good option on the list of the best 650W PSU and the others I will further share. First, Corsair deserves all the applause for manufacturing PSUs that exhibit highly professional design. The ones which are compliant with most of the consumer requirements, that too with stylish looks.

Nobody gets to see the looks of a PSU but having PC accessories with all those tech feels is every gamer’s dream. The TX650M comes in matte black color, and the design is smart. What makes this Corsair product stand out is the 80 Plus Gold rating. This offers a sky-high efficiency of 87% to 90% at loads as low as 20% and as high as 100%. The maximum efficiency is shown at 50% load. That is all which makes it the best 650W PSU for gaming. The 80 Plus Gold rating is responsible for the negligibly small amount of heat, almost 13% to 10%. So, your system is safe from the harm of heating up.

The semi-modular cable system, like the one I have discussed above, accounts for better airflow. It provides you the freedom of using the cables you desire to make the system look cleaner and more organized. The TX650M features the Rifle Bearing fan, which is 120mm thick yet performs exceptionally well. Corsair has introduced a variety of fan bearings in its products, and Rifle Bearing Fan is one of the amazing options. This bearing provides a greater life to the fan and, in turn, longevity to the cooling system.

Along with its stunning design, it has an 80 Plus Gold rating. This is the best part of Whisper M for me. Efficiency is a very crucial factor, and everyone wants a high-efficiency PSU.

This one, with its Gold certification, is said to provide an efficiency of 92% which makes it the best 80+ Gold 650W PSU. That is a big claim! But there is more to it. The Whisper M comes with all the connectivity options one could have asked for. It offers one 20+4 pin connector, two 4+4 pin CPU connectors. Along with this, you get six 6+2 Pin VGA connectors, four Molex connectors, and a total of 12 SATA connectors. It bears a high-quality fan which is responsible for the low noise produced by this system. It operates at sound levels lower than 18 dBA.

This fan is 140 mm in thickness which improves the airflow across the system. This fan has Fluid Dynamic Bearings, which increase the life span of the PSU. It also provides improved lubrication to the fan, so it works quietly. Also, you do not have to worry about fluctuating voltages. The fan of Whisper M starts working even at 3.5 volts. The heat levels produced are deficient already, and the amazing performance of this fan is the cherry on top. It works perfectly fine for the 8 to 10% heat produced.

The most prominent feature of the BeQuiet Dark Power Pro 11 is overclocking. It helps you to switch between several operations with one click. The offered overclocking options are four-rail and single-rail.

These rails are 12 V each. BeQuiet claims of introducing a virtually inaudible fan in the Power Pro 11. This is the Silent Wings 3 fan. It has 135 mm thickness and has Fluid Dynamic Bearings. Its funnel-shaped opening has improved the overall cooling process. This type of bearing is known for its improved lubrication and producing very little noise making it the best Quiet 650W PSU. It would be right to say that BeQuiet has done a lot to lower noise production. It does not mean that it has ignored other features.

You get everything you desire in the BeQuiet Dark Power Pro, especially the connectivity options. Apart from the 12V rails, you can connect a maximum of four case fans with this PSU. Besides, there are five PCIe connectors to support Graphic cards, etc. The cable system is semi-modular which gives you great convenience and freedom of choice among cables.

Corsair is back on the list with another wonderful option. It is from the RMx series launched by Corsair. This series is an upgraded version of the RM series. This series has launched PSUs that can work efficiently even at temperatures as higher as 50°C. The product under discussion is the 650W version of RMx 2018. This model displays the legacy of excellence that is exclusive to Corsair. What makes it a tough competition for others on the list. Is its cable system for me. It has a fully modular cable system.

Since most of the products on the list have a semi-modular cable system, the Corsair RMx 650W stands out of the crowd which makes it the best Premium 650W PSU. This cable system promises an even better airflow across the system. The flexibility and cable seating options have also advanced in this model. You have more liberty than the semi-modular system when it comes to cables. And if you completely want to personalize the choice of cables, go for Corsair. They have a standard of providing you with the best cable systems, whereas many other leading brands still consider it a luxury.

So, they only provide fully modular cable systems in their high-end products. This cable system has a significant impact on the temperature of the system. It is kept as low as possible to avoid heating up. Since a deficient number of wires are plugged in, installation and replacement are straightforward. The RMx 650W holds the 80 Plus Gold Certification. It delivers an efficiency of 89% at a maximum (100%) load making it the best 650W PSU. At other loads, the efficiency is 90%.

It has a very compact design and is equipped with the SFX Factor. So, it fits in easily for various PC sizes. It is a value-for-money option as it has a lot more to offer. 650 watts might not seem a big offer to many people since higher variants are also available in the market. But it is an optimum amount, and Corsair has efficiently managed to offer it with a Platinum rating at a very reasonable price.

Its design is the lightest of all options, which is a plus point for Corsair. Its fan is the smallest in size on the list, which accounts for its efficient functioning. It is 92 mm in size with Rifle bearings. It has a channel to pump the fluid stored in the reservoir to provide lubrication. This reduces operational noise and power consumption. Also, the SF600 Platinum is equipped with a semi-passive operation, because of which the fan only works at very higher loads.

By going for Eco-friendlier options, you save a lot of energy. It has the standard ATX form factor, which is compatible with ATX, mATX, EATX, HPTX, XLATX, etc. It comes with a single 12V rail. Otherwise, split rails are more beneficial, as seen in the other competing PSUs. It comes with the 80 Plus Platinum rating, which offers the highest efficiency.

I am pretty sure that Enigma G2 has made its place on your wish list, but there is still more to it. With this one in your hands, you do not have to worry about the cooling of the CPU. It bears fans with three cooling modes.

The operation of these fans is very silent. They deliver amazing performance by efficiently reducing the heat. You can also change the cooling modes when the temperature has lowered to a desirable range. The fan’s length is 120 mm, as I have already mentioned that the fan is shallow on noise. Let me add to this. With an average load, while performing routine tasks, you will not hear the fan working. It becomes muted when it has little work to do. That too, without any compromise on cooling quality. Enigma G2 improves the airflow across your system. With capacitors imported from Japan, there is no way this unit shows a technical fault. Overall, It’s the best 650W PSU due to its efficiency rating and good performance.
