The Product

Corsair AX850 Titanium PSU

Of all the PSU manufacturers out there, Corsair is possibly the one that displays great pride in their units. They thoroughly select their components with utmost care to provide everyone with optimal performance in all possible categories. With their AX1600-i, this required the company to enhance and upgrade beyond silicon, thus, transitioning to the use of gallium nitride to keep the 1600-Watt device in a small form factor while simultaneously providing users with top-notch efficiency levels.

Their AX series’ leading PSU brand is primarily reserved for the best units that they produce; so, their latest AX850 Titanium PSU maintains this aspect, moving their sub 1000-Watt AX brand to the period of 80+ titanium – the highest possible efficiency rating that is available for every consumer PSU. This device is also designed to impress and will surely deliver only the best.

The AX850 Titanium PSU from Corsair carries the branding that one would expect from the company; in other words, it’s a very sleek and classy design with silver hints and highlights. In terms of its design, the company put great effort into its style to add an appealingly aesthetic touch to it.

But despite this, the AX850 is made specifically for business purposes, hence, its sleek, classy, and sophisticated design. When looking at the AX850 Titanium PSU, it highlights the brand, Corsair, which comes off as both suitable and subtle for the entire design of the product.

Inputs that are specific for the modular power supply cables are all marked to aid users in ensuring that the proper cables are going to the right places. While some are set in a mirrored design, the top-bank cables aren’t. Though the cables link with a great level of security which is great. The rear portion of the power supply comes with adequate vents to promote passive airflow – one of the company’s designs that has the cooling fan running whenever necessary. The rear has two switches – one for the power and the other for the zero-RPM fan mode. This is generally a more enhanced version of the regular operations which decreases the fan usage.

For the fan’s design, it’s generally nice with an aesthetic design to the case that highly accentuates the horizontal divisions for air intake. This is another touch that adds more sparkle and to the design. Aesthetically, there really isn’t much to the AX850 Titanium PSU’s design, but what’s present on the device is excellence. The Corsair AX850, compared to other similar products, appears more professional and sleek; there aren’t any RGBs on it, but the PSU is just pleasing as is.

A Look Inside the Corsair AX850 TItanium PSU

The AX850 Titanium PSU’s OEM is Seasonic, while on the main PCB, you’ll find a couple of little heatsinks there. Know that the gold PSUs feature an extremely low energy loss, the reason why operational temperatures are low so you won’t need to have bigger heatsinks.

The AC holder makes use of the Yun Pen EMI line filters which include all the necessary elements for the device: an X and 2 Y capacitors, plus two coils and an MOV. You will also find a thermistor together with an electromagnetic relay that bypasses this once the PSU begins to decrease energy losses. This lets it cool down adequately. Close to the thermistor and relay is the ICE-2QR-4765 quasi resonant PWM controller which handles the PSU’s standby mode.

The bridge rectifiers, specifically the GBU-1506, are cooled passively via heatsink. In the APFC, a total of three MOSFETs separates the transitional DC voltage that comes from the bridge rectifiers into consistent pulse sequences.

The two parallel reservoir / soothing capacitors are from Nippon Chemi-Con while the two primary swatches are 60-R160-C6. The PSU makes use of the LLC resonant converter to acquire better and more enhanced efficiency; for the resonant controller, there’s a CM-6901 which is housed on a vertical daughterboard that’s positioned adjacent to the resonant inductor. The controller operates and manages the primary switches in the PWM mode at light loads, while the FM mode at increased loads. Seasonic opted to steer clear from utilizing a built-in transformer so the two transformers are used for the resonant converter, simultaneous with the primary transformer.

In the secondary, there are a number of smaller heatsinks which keep the four IPD-031N-06L MOSFETs utilized for the +12V generation. These MOSFETs are present on the solder area of the main PCB, and are also cooled from a casing via a thermal pad. With two DC-DC converters, the minor rails are generated from +12V. To minimize the distance that the current has to travel to, the converters are placed on the modular PCB. This decreases the loss of energy. The two converters make use of four PD-060N-03L MOSFETs and an APW7159 PWM controller. In the secondary portion and on the modular PCB, you will find a lot of polymer capacitors which guarantees top-notch performance, as well as longer lifetime. One of the few electrolytic capacitors present is from Nippon Chemi-Con and is used in 5VSB regulation.

For the PSU protections, these handle a PS-223 which has been included by an LM-393 Dual Voltage Comparator. The San Ace 120 cooling fan that is present in the CPU is provided by SANYO DENKI. Furthermore, the workmanship and soldering quality of the Corsair AX850 Titanium PSU is really high.
