Corsair HX850 PSU Review

One of Corsair’s newest PSU households is the revamped HX sequence, which contains four fashions with capacities ranging from 750W to 1200W. All of them attribute completely modular cabling, 80 PLUS Platinum and ETA-B certifications, and quiet operation under the toughest conditions.

The largest distinction between the HX and pricier HXi fashions is the earlier’s lack of a digital interface, which suggests they don’t get the benefit of partial fan administration and monitoring by way of the Corsair Link software program program. But the HX PSUs do embody Corsair’s Type 4 cables, that features additional filtering caps and further sense wires on the 24-pin ATX connector. As a end result, we rely on increased ripple suppression and tighter load regulation compared with the supposedly higher-performance HXi fashions. We do think about that Corsair will rapidly start bundling the Type 4 cables with its HXi sequence as successfully, though, to close this uncommon effectivity gap.

Interestingly, the HXes aren’t cheaper than the HXis, notably when you check out the lower-capacity variations. When this evaluation was written, the HX850i supplied for merely $10 higher than the HX850, making it a no brainer for fanatics wishing to control the flexibility present’s fan profile and monitor its effectivity. 

We already reviewed the HX1200 and HX1000, so now we have now a reasonably good thought how the HX family performs. Today we’re turning our consideration to the next-in-line HX850. It’s extremely efficient ample to accommodate a high-end PC with higher than two graphics enjoying playing cards and a potent CPU. Because the HX850 has just a few EPS connectors, it won’t face any compatibility points with motherboards needing higher than one EPS socket, each. In our opinion, all 850W PSUs must be organize this way. But it appears as if not all of Corsair’s rivals agrees.

Specifications

Besides its 80 PLUS Platinum rating, this PSU moreover carries the ETA-B and LAMBDA-A+ effectivity and noise certifications from Cybenetics. Its excessive working temperature for 100% output is prepared at 50°C, as a result of the ATX spec dictates. In addition, the PSU is roofed by all obligatory security choices, along with OTP and OCP on the +12V rails (when various +12V rails are enabled by way of a swap positioned on the once more).

The cooling fan is comparable one found on all of Corsair’s high-end vitality supplies. It makes use of a fluid dynamic bearing and has a low most tempo, so even in worst-case conditions it doesn’t make so much noise.

Finally, a 10-year assure is one of the longest overlaying an affect present. Only Seasonic supplies one factor longer: its Prime fashions attribute 12-year safety.

Corsair serves up close to 71A on the +12V rail, 3A for the 5VSB rail, and 150W most combined vitality for the minor rails. The 5V and 3.3V rails of similar-capacity PSUs usually aren’t as sturdy. But we have now moreover noticed that, usually, their OCP triggering elements are moreover set very extreme.

There are two EPS and six PCIe connectors, along with 16 SATA and six peripheral ones. Corsair’s cable measurement is satisfactory. However, we cannot say the equivalent for the house between SATA and peripheral connectors, which is just too small.

Power Distribution

There is a swap that lets you choose between one +12V rail or various +12V rails. Across the HXi family, that’s achieved using Corsair Link software program program. However, as a result of the HX fashions do not need a digital interface, a definite technique had to be used.

The +12V rails can ship as a lot as 40A each in multi-rail mode. According to Corsair, each specific individual connector has over-current security, so no more than 40A goes by way of any given cable.
