CORSAIR HX series power supplies give you extremely tight voltage regulation, quiet operation, Platinum-certified efficiency, and a fully modular cable set. Credit subject to status, UK residents only, Box Limited acts as a broker and offers finance from PayPal Credit. The new HX850 comes with a full list of protections including short circuit, over voltage, over current, over power and over temperature protections. About 20% of the units we have tested seem to have found the sweet spot of 1%-2% regulation and the Corsair HX1050 is right in that sweet spot. within its nominal load range (20% to 100% of the unit's capacity) and gave us fairly good efficiency readings under low loads.

As a result, we expect better ripple suppression and tighter load regulation compared to the supposedly higher-performance HXi models. Because the HX850 has a couple of EPS connectors, it won't face any compatibility problems with motherboards needing more than one EPS socket, either. Since the fan doesn’t turn on until it’s needed, you’ll enjoy virtually silent operation at low and medium loads. In addition, the PSU is covered by all necessary protection features, including OTP and OCP on the +12V rails (when multiple +12V rails are enabled through a switch located on the back). This result however does not mean that the unit’s certifications are false, just that it received its efficiency rating with an input voltage of 110 VAC, under which the 80Plus directive is slightly more lenient.The 135 mm fan responsible for the cooling needs of the HX850 is the Corsair NR135P, a fan we frequently see in the company’s high-performance PSUs. GHz, NH D15, 32 GB DDR4 3200 GSKILL Trident Z RGB, AORUS Z390 MASTER, EVGA RTX 3080 FTW3 Ultra, Samsung 970 EVO Plus 500GB, Samsung 860 EVO 1TB, Samsung 860 EVO 500GB, ASUS ROG Swift PG279Q 27", Steel Series APEX PRO, Logitech Gaming Pro Mouse, CM Master Case 5, Corsair AXI 1600W Titanium. We can see that the plastic sheet on the fan above means the air is directed towards the SR MOSFET's, temperature thermistor and the secondary capacitors.

The easy-to-install, fully modular setup on the Corsair HX850 Platinum PSU allows you to combine the low-profile cables provided for a great-looking build.Add in the seven year warranty and for many it was a no-brainer that this was the power supply to have for mid-range systems. You can toggle the rail modes using the switch on the PSU, In the SINGLE position, the full output capability of the power supply’s +12V rail is available to any and all connectors, while on MULTIPLE each connector has Over-Current Protection so no more than 40A of current can be delivered to each cable.
