High efficiency even at low loads, Great ripple/noise suppression, On of the very few PSUs that passed successfully all Advanced Transient Response tests, Very quiet operation since the fan does not spin at low loads and when the PSU's temperature is low, High manufacturing quality, Fully modular, 7 years warranty
Loose voltage regulation at 3.3V, but still within 5% range
The AX850 proved to be a solid performer. Although its voltage regulation was not jaw dropping, +12V and 5V rails stayed under 3% and only 3.3V reached 4% deviation. The high efficiency levels even under very high ambient temperatures, the excellent ri...
Abstract: At the heart of any performance PC is a critical component, without which the rest of the machine can't function. Can you guess what it is? Those who said motherboard... got it entirely wrong. Without a decent PSU, it doesn't matter how stable or overc...
Up to 850W DC output, rated at 50°C, Excellent efficiency (80Plus Gold certified), Stable voltages with good voltage regulation, Very clean DC outputs with low AC ripple, Silent to Quiet during normal operation, Very good build quality with high qual
Using four PCIE cables/connectors excludes using dual EPS connectors
Corsair is well known for producing some of the best PC power supplies on the market today and the AX850 continues that trend. The Corsair Professional Series Gold AX850 power supply delivers very clean DC outputs, with excellent efficiency and good...
How best to put this......the Corsair AX850 is an outstanding entry into the 850W segment that's only real competition, that we have reviewed and is readily available at this time, is the Corsair HX850. The single best, and most distinctive, feature of...
Corsair power supplies have been winning praise from web tech reviewers since day one. The AX850 is certainly no exception. It is a winning power supply in every way — electrical performance is tops, efficiency is high enough for 80 Plus Gold, the bui...
The new Corsair AX850W is an outstanding power supply. During our tests it achieved very high efficiency, peaking above 90%, voltages very close to their nominal values (3% regulation instead of the traditional 5% regulation), extremely low noise and r...
Efficiency just below 80 Plus Gold, Quiet, especially when the fan didn't spin at all!, Decent voltage regulation, Fully modular, Good ripple suppression,
Nothing really bad to say here,
Computer power supplies have come a long way in just the last couple of years. With the implementation of resonant mode topologies and DC to DC converters for non-primary DC output, we've seen efficiency increase more and more. The AX850 is an example ...
Excellent DC voltage load regulation, Low AC noise/ripple, 80 Plus Gold certification, Silent fan control technology, Seven year warranty, Plenty of connectors...
Unexpected efficiency of 83% at 100% DC load on 110 VAC (following the OCC testing methodology)...
Price Per the Watt: Power Supply Corsair AX850 850W at $199.99 = $0.23/Watt (08-2010) The Corsair AX850 performed very well during testing. However, following the OCC testing methodology, the efficiency figures were a little disappointing, especi...
It seems Corsair can do no wrong lately, and if they keep producing quality power supplies like the AX850 and AX1200 then they will quickly earn a massive following....
When we review a PSU range such as the Professional Series Gold and find its top model, the AX1200, to be so exceptional the expectation placed on the rest of the family is huge. In an ideal world people would probably like to see the exact same deign...
