CORSAIR AX1000

CORSAIR AX1000

CORSAIR power supplies are no doubt the best power supplies on the planet you could get and the company charges a high price for their products as well. The OEM for their power supplies is Seasonic most of the time, which is why the quality of their products is top-notch. CORSAIR AX1000 belongs to the flagship AX-series power supplies, which come with high-end features that the low-tier PSUs do not come with. 

ModelCORSAIR AX1000
Continuous Power1000W
Efficiency80 Plus Titanium
PSU Form FactorATX
+12V Rail Current83A

The looks of the power supply are nothing special but it looks very decent due to simple design. There is written AX1000 in large font along with the CORSAIR logo at the side while the top side has only a small CORSAIR logo. You can change the side sticker, as the power supply comes with stickers having other colors.

CORSAIR AX1000 is an ATX power supply having a continuous power rating of 1000 watts. This power supply is also one of the latest power supplies from the company and it has an 80 Plus Titanium and ETA-A+ rating, which means that it has over 94% efficiency on 50% load and over 90% efficiency on any other load. There is a 135 mm Fluid Dynamic Bearing Fan in the PSU which keeps it cool during high loads and can run passively as well, keeping the power supply quite silent.

Coming to the current supply of the PSU, CORSAIR AX1000 provides 83A through a single +12V rail, which makes it highly capable of running high-end multiple-GPU systems, as 83A results in 996 watts of power. Moreover, it has 25A on the +3.3V rail, 25A on the +5V rail, 0.3A on the -12V rail, and 3A on the +5VSB rail. Overall, the combined power of the power supply cannot surpass 1000 watts.

As for protection features, CORSAIR AX1000 comes with Over Voltage Protection, Under Voltage Protection, Over Power Protection, Over Temperature Protection, Over Current Protection, and Short Circuit Protection. This makes it great for those people who are living in an area having a lot of electrical surges.

Coming to connector counts, CORSAIR AX1000 is a fully modular power supply that comes with a lot of cables, resulting in 1 x ATX connector, 2 x 4+4 pin EPS12V connectors, 8 x 6+2 pin PCIe connectors, 16 x SATA connectors, 8 x 4-pin Molex connectors, and 1 x FDD adapter. This means that you can even run two of the most power-hungry graphics cards, even if the power requirement of the graphics card is over 300 watts. If you want to run a Quad-GPU setup, it would be better to go with the higher-powered CORSAIR AX1600i power supply.

Conclusion

CORSAIR AX1000 is the best of the best when it comes to reliability and that is why it comes with a 10-year warranty as well. This power supply is going to be great for enthusiasts who are into extreme overclocking and want supreme stability in their system. With an 80 Plus Titanium rating, you would be having lower heat emission as well compared to other power supplies, although its 135mm fan is capable of handling a lot of heat.

Pros
  • Comes with 80 Plus Titanium and ETA-A+ rating
  • Simple looks
  • Lots of protection features
Cons
  • Quite expensive for mid-range users

EVGA Supernova 1000 T2

EVGA Supernova 1000 T2

EVGA is quite a competitor to CORSAIR in power supplies, despite having a much lower share in the market. Their Supernova series is quite famous and covers a wide range of power supplies having both low-tier and high-tier models. EVGA Supernova 1000 T2 is among the flagship models of the company and comes with a lot of high-end features.

ModelEVGA Supernova 1000 T2
Continuous Power1000W
Efficiency80 Plus Titanium
PSU Form FactorATX
+12V Rail Current83.3A

EVGA Supernova is quite similar to CORSAIR AX1000 when it comes to technical specifications, however, the design of the PSU is quite different. The PSU has a specification table at the side along with the model of the power supply while the top has EVGA Supernova 1000 T2 written on it. The matte texture of the power supply feels really good and it would complement matte-textured casings. There is an Eco-mode button along the area of the connectors, which makes the PSU run as a fanless PSU below a certain temperature range.

Coming to the technical specifications, the PSU comes with an 80 Plus Titanium rating and has a 140mm double ball-bearing fan in it. The PSU can supply 83.3A on the +12V rail, which is even higher than the CORSAIR AX1000, although not by miles. On the +3.3V rail, it has a rating of 20A; 20A on the +5V rail, 0.5A on the -12V rail, and 2.5A on the +5VSB rail.

The power supply unit comes with Over Voltage Protection, Under Voltage Protection, Over Current Protection, Over Power Protection, Short Circuit Protection, and Over Temperature Protection, which is quite similar to the AX1000.

As for the connectors, this PSU is also a fully-modular unit like CORSAIR AX1000, however, the connector-count is lower than AX1000. It comes with 1 x ATX connector, 2 x 4+4 pin EPS12V connectors, 4 x 6+2 pin PCIe connectors, 2 x 6-pin PCIe connectors, 12 x SATA connectors, 6 x 4-pin Molex connectors, and 1 x 5.25″ to 3.5″ adapter.

Conclusion

EVGA Supernova 1000 T2 is a great alternative to CORSAIR AX1000 and it has similar technical specifications, which is why you can buy this PSU instead of AX1000 if you lean towards EVGA customer support, which is often considered one of the best in the league. The warranty of the PSU is also 10 years like the AX1000 and so are the protection features and efficiency rating. 

Pros
  • Uses a large 140mm fan
  • Eco-mode button on the unit
Cons
  • Even pricier than AX1000

Seasonic PRIME FANLESS TX-700

Seasonic PRIME FANLESS TX-700

SEASONIC although manufactures power supplies for other companies like CORSAIR, the company also designs power supplies under its name. Seasonic is one of the largest manufacturers of power supplies and creates power supplies for other industrial solutions as well apart from computers. Seasonic PRIME FANLESS series power supplies are one of the finest power supplies by the company, that are designed without a fan and since fanless design results in high thermals, these power supplies have a very high efficiency rating, to reduce the thermals.

ModelSeasonic PRIME FANLESS TX-700
Continuous Power700W
Efficiency80 Plus Titanium
PSU Form FactorATX
+12V Rail Current58A

Since this is a fanless PSU, the design of the power supply is quite interesting. The whole outer shell of the power supply has large vents to compensate for the performance loss due to the absence of a fan. This not only does work but it also improves the looks of the system. Even on the connectors’ side, there are vents for airflow and there is a small PRIME logo at the top. 

This power supply is also 80 Plus Titanium certified which means that you won’t have to deal with a lot of heat, which is one the reasons that this power supply is functional because, with low-end power supplies, the presence of a fan is a must; after all, lower efficiency leads to high heat emission. For protection, the power supply supports Over Power Protection, Over Voltage Protection, Under Voltage Protection, Over Current Protection, Over Temperature Protection, and Short Circuit Protection. Now for the voltage rails, the PSU supports 58A through the +12V rail, 20A through the +3.3V rail, 20A through the +5.5V rail, 0.3A through the -12V rail, and 3A through the +5VSB rail, where the total continuous power is rated at 700 watts.

This configuration of power is perfect for most of the PC users because most people use a single graphics card and the overall power requirement of the computer is around 300-400 watts, where the efficiency rating of the PSU is highest (40 – 50%) and fanless approach makes the PSU completely silent, which is a great thing for those people who want to build a silent computer system. Moreover, the power supply comes with the longest warranty on the list that is 12 years.

Now, coming to the connectors of the power supply, the PSU supports 1 x ATX connector, 2 x 4+4 pin EPS12V connectors, 6 x 6+2 pin PCIe connectors, 20 x SATA connectors, 5 x Molex connectors, 2 x Molex to SATA 3.3 adapters, 1 x Molex to FDD adapters. 

Conclusion

Seasonic PRIME FANLESS TX-700 is the perfect power supply for most PC users, having a super-high efficiency and silent operation due to the absence of a fan. The power supply power rating makes it excellent for any single-GPU user who wants top of the line performance. If you don’t intend to use multiple graphics cards in your system, this power supply is one of the best you can get.

Pros
  • Silent operation
  • Unique design
  • 80 Plus Titanium efficiency
Cons
  • A bit pricey for a 700W PSU
