Seasonic PRIME Fanless PX-450

Power Efficient PSU

The PRIME Fanless PX series of power supplies use fanless technology to eliminate noise. This is especially important in situations that require a quiet operation.

It is made of high-quality components and features a modern circuit design and fully modular cables. These also allow for more cable management. With the PRIME Fanless PX-450 PSU, you can finally enjoy the quiet operation of your system.

While this power supply is fairly inexpensive compared to other fanless power supplies, it still does have its drawbacks.

For one, its fanless design means that you can use only the cables that you need. Additionally, this fanless power supply will keep your computer cool and clean. This system is 80 PLUS Platinum-certified and comes with a twelve-year warranty. It will not break the bank, but it is definitely worth the money.

This power supply features 80+ Platinum certifications, 100% modular design, and completely silent operation.

Its regulated output voltage is within a tight range, and the power consumption is below 0.5 percent. This power supply is ideal for high-performance systems and can power configurations with the most demanding components.

Because it uses passive cooling based on heat dissipation, it is quieter and more efficient than other power supplies. It also helps you save money on your utility bills by reducing energy consumption.


The EVGA 750 GQ ATX12V and EPS12V power supplies have a single +12 V rail and can provide up to 62.4 A of output.

They also feature an Eco mode and a single-phase design that eliminates unnecessary wires. Moreover, the unit's active clamp circuit layout and ECO mode allow for silent operation during low-to-moderate loads.

The GQ series is EVGA's answer to the price-conscious consumer. EVGA 750 GQ power supplies come with 80 Plus Gold certification and a five-year warranty. They feature a 750-watt capacity and an 850-watt capacity.

However, they do not include over-temperature protection and do not offer ripple suppression. These power supplies aren't the cheapest options on the market, so it is important to consider the features that are important to you before buying one.

If you're in the market for a new power supply, you've probably already heard about the W1 and N1 lines.

While they are both entry-level power supplies, they are still highly efficient and compact. Corsair offers a great selection, including the RM series, which is very quiet. You can even purchase a replacement for your old power supply with the EVGA 750 GQ.

EVGA also offers a 10-year warranty on its power supplies, which is uncommon among PSU manufacturers. This warranty covers all models, though sometimes you can get a promo that adds an extra two years.

EVGA T series power supplies are among the best energy-efficient options on the market. Additionally, some good power supply makers include Super Flower. This is the best way to determine which power supply is right for your needs and budget.

Considering the price difference between the two, it's hard to choose between the EVGA 750 GQ and Corsair 750 GQ. For the price difference, the SuperNOVA P2 features a more powerful fan, and Corsair's fan is smaller but louder.

Both units feature an excellent warranty and come with excellent reviews. The Corsair RM750X has better warranty coverage than EVGA.

Corsair SF750

The CORSAIR SF750 80 PLUS Platinum SFX Power Supply is a remarkable and extremely power-dense PSU for the most cutting-edge small-form-factor PCs.

Featuring a silent and ultra-efficient design, this power supply is equipped with a 92-mm fan. Premium electrical components such as 105-degree Japanese capacitors ensure optimal thermal performance.

This powerful power supply is compatible with most top-tier SFX builds and is even suitable for large ATX cases. However, because it is extremely powerful, it is quite expensive and will cost a pretty penny.

It should be a no-brainer for high-end PCs but may be too expensive for some budget-conscious users. Regardless of the price, this SFX power supply is definitely worth the investment.

Its impressive efficiency levels have made it a top choice for power supply units for gaming systems. The SF750 Platinum has achieved a high efficiency rating of eighty percent at full load. This impressive performance is made possible by the presence of an active PFC.

The Corsair SF750 Platinum's power factor is 0.99, which means it uses less power during the idle state. It also meets the ERP standards, so you'll be getting the best out of your power supply.

While the Corsair SF750 is highly efficient, it's not the best choice for a low-end gaming build. For a lower-end build, an ATX power supply can be added to a smaller case. Then again, the SF750 is very small and takes up less space than its 750-watt counterpart.

Also, many SFX power supplies can be added to an ATX case with a bracket. Regardless of the power supply's size, the best power supply for your gaming system should be able to handle high-end GPUs and other components.

Thermaltake Smart 700

With an A+ LAMBDA rating, the Thermaltake Smart RGB 700W is the most energy-efficient PSU available. It has an enviable compact build, comes with cables already attached, and boasts a 700W rated capacity.

The Smart RGB 700W is a great choice for gamers because of its 256 color RGB Cycle and 10 LED Light Bulbs. It also boasts an 87% efficiency rating and is 80 PLUS certified, which means it will be the most efficient PSU on the market.

The Thermaltake Smart RGB 700W PSU is a fantastic choice for those on a budget. With a price tag under PS60, it's the perfect match for the majority of enthusiasts.

Its single +12V rail eliminates voltage distribution limitations, providing powerful, stable power to your CPU and VGA. The Smart RGB 700W is also one of the most affordable PSUs on the market.

Despite the fact that it doesn't earn a bronze efficiency rating, the Smart RGB 700w is still a power supply worthy of a high-end gaming system. It boasts good efficiency levels, and its 750W capacity is more than sufficient for most needs. It also comes with a five-year warranty.

In addition to its efficiency, the Smart RGB 700w is quiet and has a low noise level.

With an 80 PLUS Certification, the Thermaltake Smart 700 is a highly affordable power solution for gamers. Thermaltake offers 80+ Certified models and a five-year warranty.

The newest generation of Smart 700 has a Quad Output field-programmable power supply and supports the NU2 sPS5000 App. This makes Thermaltake Smart 700 a highly flexible, convenient, and reliable power supply for gamers.
