  • The only enthusiast PSU to use Totem-pole PFC Gallium Nitride (GaN) transistors for superior efficiency in a smaller form-factor over traditional silicon parts

The Corsair AX1600i is the best PSU that you should pay your money to buy. It offers performance in a great way. Its platform is developed at an amazing level providing a peek at the innovative technology of power supply design.

Besides its super efficiency, the AX1600i also can load at a high rate , amazing transient response, a long hold-up time, and unparalleled ripple suppression. Moreover,  it operates  quietly. With the high quality FBD fan, this PSU enabled cooling the system even under hard load . The AX1600i offers the Corsair Link software enabling you to choose between three options of fans: performance, balanced, and quiet.

Pros

  • Full power at 48°C
  • Efficient and powerful energy
  • Load regulation
  • Ripple suppression
  • Hold-up time
  • The Power Ok signal is accurate
  • It runs quietly

Corsair AX 1000

CORSAIR AX Series, AX1000, 1000 Watt, 80+ Titanium Certified, Fully Modular Power Supply
  • 80+ Titanium Certified for the highest level of efficiency and performance
  • Zero RPM fan mode for near-silent operation at low to medium loads
  • World Class electrical performance for incredibly stable voltages and ultra-low ripple noise

I find Corsair’s AX1000 not only the highest possible performance but also quiet operation. So, I strongly recommend you don’t hesitate to take it into account. This 1kW power supply  impressed me by its tight load regulation on all of its rails, amazing ripple suppression, crazy-high efficiency levels and brilliant transient response.

Another feature that I am interested in is that the high efficiency platform keeps thermal loads low, resulting in the fan not needing to work hard and temperatures that are low. That is the reason why the system runs so quietly.

Pros

  • Solid build quality
  • Efficiency is high
  • Selectable semi-passive mode
  • 10-year warranty

Cons

  • Using 16 AWG wires
  • Short distance connectors

  • Zero RPM Fan Mode: Virtually silent operation at low and medium loads
  • Fully modular, clutter free, Para cord sleeved cables: Flexible triple layer mesh Para cord sleeves for easy cable routing and elegant aesthetics
  • 100% All Japanese 105°C capacitors: Premium internal components ensure solid power delivery and long term reliability

The Corsair RM750x is impressive because it offers high quality features while its price is still pretty reasonable. It consumps a low energy of 750W and it is 80 Plus Gold Certified. Besides, it is highly efficient even when fully loaded, up to 92% of energy efficiency.

Moreover, it is equipped with full modular cables, a quiet fan, and durable and strong capacitors. The “standby support” program works impressively accurately. It enables users to start the PCs within 5 seconds from hold-up mode.

The Corsair RM750x not only consumps a low amount of power but also provides an excellent cooling control and good noise management under operating.

Pros

  • It has a small physical size, packed dimension
  • Great power efficiency of 92%
  • Fully modular Cable

Cons

  • 5-year warranty

Corsair CX Series 550

Sale
Corsair CX Series 550 Watt 80 Plus Bronze Certified Modular Power Supply (CP-9020102-NA)
  • 80 Plus bronze certified: High efficiency operation for less excess heat and lower operating costs. Compatibility supports ATX12V 2.4/2.3/2.2/2.01 and EPS12V 2.92 standards
  • Thermally controlled fan: Silent operation at low and medium loads. Fan size is 4.72 inch
  • Semi-Modular: Make your builds and upgrades easy, with clean, great-looking results

I was looking for a PSU that is highly reliable, low-noise, and installed easily, and I searched the name CX Series Modular power supply units. Many users determined it  as a fantabulous option, and I believe they are true. 

The flexible modular cabling system means I only need the suitable cables, and 80 PLUS Bronze certified efficiency allows my PC less excess heat, makes lower noise, and consump lower power. 

Thanks to owning the large-diameter, the CX Series reduces noise even when I am pushing my system hard. In addition, the matte finish, sleeved cables and connectors are all in black make the system look more high-tech.

Target customers of Corsair’s CX line are those who still want a famous, authentic, trustworthy PSU but tight budgets .

Pros

  • High reliability
  • Low noise
  • Easy installation
  • +100 Watt available

Cons

  • Not suitable for gaming purpose

Cooler Master MPY-7501-AFAAG-US

Cooler Master MPY-7501-AFAAG-US MWE 750 Gold Full Modular, 80+ Gold Certified 750W Power Supply, 5...
  • Full modular flat cables: Full modular flat cables are easy to install, reduce clutter, and maximize airflow
  • 80 plus gold certified: The 80 plus gold certification guaranties a minimum typical efficiency of 90 percent
  • Durable and silent LDB bearing: silence technology combines sealed LDB bearings with quiet fan blades delivering a long lifetime of quiet cooling

Although Cooler Master MPY 750W makes me satisfied with its high build quality, longer using time, I have to say the Cooler Master MPY V750 Gold is quite expensive for what it offers.  In spite of the high price, this PSU achieves a satisfactory overall performance, but it is expensive and quite noisy, once stressed.

This unit has a maximum output capacity of 1020 watts which allows your PCs to operate strongly. Besides, it  offers an active PFC model. The 135 mm fan type makes the dimension be quite compact.

Pros

  • High build quality
  • Long hold up time
  • 10 years warranty
  • Fully modular

Cons

  • Noisy when heavy load
  • Connectors have small distance 

Cooler Master MWE Bronze 600 Modular 80+ Bronze

Sale
Cooler Master MWE Bronze 600 80+ Bronze 600W PSU with 120mm Silencio FB Fan, Sleeved Cables
  • 600W ATX Power supply
  • 80 plus Bronze certified
  • Temperature controlled 120mm fan with dustproof LDB bearing

I think Cooler Master MWE 600 Bronze  is suitable for those who are looking for an economic option. This item offers five models with capacities of 450W to 650W but all of them are not equipped with modular cabling so that it can reduce its price. But in general, the quality is good thanks to using DC-DC converters for generating slight and small rails and Teapo capacitors.

This item uses a temperature controlled 120mm fan with dustproof LDB bearing which looks so compact. Moreover, a three-year warranty is not long in comparison with other brands but I think that’s enough. I don’t know much about their real-life performance and how efficient their true output noise is. 

Another interesting feature of the MWE PSUs is the compact footprint, which will allow me to install easily at least to some degree, for the lack of modular cables.

Pros

  • High reliability
  • Low noise
  • Easy installation
  • +100 Watt available

Cons

  • Only 3 year warranty
  • Not in Cybernetics Rating

Sale
Thermaltake Toughpower 1500W 80 Plus Gold Semi Modular PSU ATX 12V or EPS 12V Ultra Quiet Power...
  • 80 PLUS GOLD Certified
  • High Quality Japanese Capacitors
  • Continuous Power Design

I think the price is a big problem when you think of this item. It really costs a bomb. However, I can not deny that it is a very strong and rich featured PSU in this price range.

With such a high price tag I expected a fully digital platform and not an analogue one which just uses an MCU for handling the digital bridge between the PSU and the system.

Pros

  • Operating efficiently up to 49.5 °C
  • Amazing capacity
  • Low inrush current
  • Quality caps
  • Remote shutdown/restart feature

Cons

  • Noisy if computer have to load hard
  • Power good signal is inaccurate
  • Short USB cable

  • 256 Color RGB Cycle with variants including Solid Red, Green, Blue, White, and a LED Off mode
  • 80 plus Bronze Certified

The most feature that impresses me about this Thermaltake Smart BX1 is the solid 256 Color RGB Cycle and a LED Off mode which provides your PC high quality colorful display. This item costs a medium price that is neither cheap nor too expensive. In this price range, it is really worth a try. Moreover, the noise control system works efficiently, so the PC runs quietly at an amazing level.

Pros

  • 80 plus Bronze Certified
  • Better Cooling
  • High Quality Japanese Main Capacitor
  • 10 LED fan with 7 colors.

  • 100% Japanese Capacitors ensure long-term reliability

The 850 P2 is an ideal PSU for a system. Two graphics cards which need less than 300W of power each easily support a couple of super VGA like GeForce GTX 980 Tis, along with a strong CPU. Besides Platinum efficiency, the 850 P2 also reduces mess by using full modular and a semi-passive operation that allows cooling fans to save power as unnecessary. Moreover, EVGA provides a 10-year warranty for its products. 

Strengths of this product is its low noise operation (even under hard conditions), the durable Japanese caps using high quality electrolyte with higher reliability.

Pros

  • Cable length is sufficient
  • The ideal distance between the connectors

The EVGA SuperNOVA 850 G3 PSU is highly competitive, performing high quality, packing higher capacity into small cases of just 15cm depth. And in addition to its smaller dimensions, it also possesses a hydro dynamic bearing in a 130mm fan. I am interested in it’s the innovative cooling fan.

The EVGA SuperNOVA 220-G3-0850-X1 is so strong that it can power a high-end gaming PC or workstation. Fully modular, warranty of 10 years, higher efficiency at 5VSB and a less aggressive fan profile make it be close to perfection in my opinion.

  • Efficient
  • Ripple suppression
  • Load regulation
  • Accurate Power Ok signal
  • Typical load efficiency is higher than 91%
  • Reducing clutter
  • Airflow is enhanced so that cooling is better.
  • 10-years limited warranty.

Cons

How To Choose The Best Psu Brands

best psu brands

When you look for the ideal PSU to buy, there are many factors determining the ultimate choice. The list should include reliability, warranty, and trustworthiness of the manufacturer. And so, it’s important for you to do your research on all the most famous brand names to finally come to which one manufacturer satisfíe your requirements. 

There are few elements you should think of before you make your buying decision:

Suitable Power Calculator For Using Purpose

It’s important for you to find out how much wattage your system requires. You should make a calculation roughly before purchasing. This step will help you get the power supply that satisfies your demands.

best psu brands

It is so common to think that a high wattage PSU provides better performance. It is true but the problem is that high capacity power supplies cost much more than lower ones. And another truth is that most computers don’t need high power.

If you do not have to run your PC at full capacity, I recommend that a wattage of 600 for a PSU is enough.

If you are a gamer, your PC needs a higher power to deal with higher graphics performance. For example, even though your computer can work on 1000 watts PSU, it’s better to look for a higher power PSU for a gaming purpose.

Besides, remember to choose the right brand that provides higher power service on their available products.

Choosing the right size PSU that fits perfectly with your physical case is a noticeably important thing. There are many sizes of PSU on the market. You have to  make sure that your PC case’s physical size is standard 5.5 inches size or longer. You definitely don’t want to buy a PSU that you can not use. For that reason, remember to check the size of your PC case carefully before picking a brand.

Which Modular Power Supply Is For PC Clean Working?

Another crucial element to think over is how to pick the module power supply for the PC to work smoothly.

Ask yourself whether you need a modular PSU that offers a clean build or a tiny one? If you want easily set up by cable-wrapping the wires that are lying and hiding them, you should buy a case having large space. So, make sure that you have to pay extra for a larger space module.

Moreover, a little vast, big PSUs usually have better cooling control systems and often include highly developed components making them more well built.

Have A Look At The Efficiency Ratings

Efficiency figures are remarkably important to consider when it comes to buying a PSU. The PSUs with high rates of efficiency often either consume less energy nor produce less heat. This makes them much cheaper to operate. Look for PSUs that have an “80 Plus” certification signifying that they are at least 80% efficient.

Pick The Popular Brands

Although I put this tip at the bottom of the should-do list,  picking the well-known names of this section is one of the most important things you should follow when thinking of purchasing a power supply. The reliable brands tend to take their “brand name status” more seriously. This means that they will manufacture and supply really quality products that are tested carefully before distributing.

One more benefit of buying PSU from these brands is they offer better after-sale customer service. When their components go something wrong, you can call them for support properly.
