Corsair, a worldwide designer and supplier of high-performance components to the PC gaming hardware market, today announced the new Professional Series Gold AX1200, AX850 and AX750 fully-modular power supply units, with 80 PLUS GOLD certification.

The Professional Series Gold range of power supplies have been designed from the ground-up by Corsair's engineers to be the highest-performing and most technologically-advanced PSUs on the market. Built utilizing server-grade power train architectures designed for mission-critical levels of voltage stability and reliability, Professional Series Gold power supplies deliver previously unheard-of levels of performance.

No Hotlinking!

Corsair Professional Series Gold power supplies exceed the requirements for 80 Plus Gold certification, delivering over 90% efficiency at 50% load when using a 115V AC input. This increases to over 92% efficiency when used with the 230V AC voltage input specification in Europe. Combined with an advanced cooling design, Corsair Professional Series Gold PSUs are exceptionally quiet and efficient.

To achieve these benchmark levels of efficiency, voltage stability, and reliability, Corsair incorporated numerous sophisticated server-level technologies. These include Zero Voltage Switching and Zero Current Switching technology to eliminate switching losses and reduce EMI, and individual DC-to-DC voltage regulation for the 3.3V, 5V and 12V rails. The use of secondary-side synchronous rectification and an advanced 4-layer PCB results in unusually low levels of ripple and noise.

The Corsair Professional Series Gold AX1200, AX850 and AX750 PSUs feature a fully-modular low-profile cable set. This allows the system builder to use only those cables that are needed, reducing cable clutter and maximizing airflow through the PC. All Professional Series Gold power supplies are able to continuously sustain their full rated output at an ambient temperature of up to 50°C, which means that they continue to provide outstanding performance even at elevated temperatures.

Corsair Professional Series Gold power supplies are provided with a seven year limited warranty, and are backed up by Corsair's legendary customer service and technical support.
 
Did anyone say Sea Sonic rebrand....

They look very similar, will have to look at 80 Plus site to see which is actually better, but IMO the Seasonic 750 is currently the best PSU on the market for most people.
 
True, but i would have expected Corsair to put their own mark on these, something special, i suppose we'll have to wait until we see what cables they have used, or what the noise of the fan is. At least we have a price on the seasonic, if the corsair is a lot cheaper, you have to wonder where the savings will be.
 
I can now confirm Seasonic have not made these units. However due to NDA reasons I cannot confirm who make them.

Also the largest Nordic review/hardware site have posted this about them.

voltages don’t vary by more than 1.5%, maximum ripple was 14mV and the maximum efficiency value was 92.5%

These are shaping up to be amazingly good PSU's.

How secretive :). I watched a video about these PSU and they said they were using a server based PSU design, interesting, im guessing Lineage Power??
The 2 units look very similar though, even the split 24 pin connector, probably would have had to work on the PCB design a lot for a consumer level if it was a server PSU.

EDIT : Redbeard just confirmed over at jonnyG that they are infact seasonic X series based, apart from the 1200W

As mentioned above, they look like they are going to be expensive but I've been after a decent PSU for a while and these might fit.

I like the all black solid look - match the inside of my gaming PC perfectly.

Ah seems you are correct. The 1200w is not seasonic. But rest assured its a quality OEM. One of the best, if not the best!

Did you NDA not apply here after all?

Just curious as to why they didnt use just 1 OEM, if the OEM can do 1200W Gold then surely it can do the lower wattage models.

Suppose they shopped about and picked the best from each level- they are reaching such crazy standards of efficiencysmall differences might mean simple scaling isn't as efficient or cost effective.

Not that cost effective will even be a mild factor here.

As Corsair leaked the info directly, this nullifys any NDA's :p

Plus they gave me permission to leak the info :)
 
Corsair have used the same 2 OEM's in the past but, they have a specific 'recipe' of their own specification parts that go into each PSU. Just because, for example, Seasonic made a PSU for Corsair, it doesn't mean its the same PSU.

Corsair did EXACTLY the same with the H-50. Asetek approached Corsair to take it to market after it didn't sell so well into big SI's like HP under Asetek's "LCLC" name. Corsair upgraded the pump, contact plate and changed the RAD.

In short, these won't be standard rebrands from Seasonic or anybody else. ;)
 
Love the sig, Ace. :)



Next PSU I get will more than likely be a corsair modular, could be a while waiting though (I hope). I assume that most psu's have a lower efficiency rating, 80 - 85%, so these must be something a bit special.
