Cooler Grasp is a widely known model amongst fanatics. The agency started as a maker of PC cooling programs and quickly moved into circumstances and energy provides, that are liable for most of its current renown. At this time, the agency enjoys world recognition and manufactures a whole bunch of merchandise, however they by no means cease updating and upgrading their catalogs.
Though Cooler Grasp did diversify in direction of gaming PC peripherals and even related furnishings, the corporate stays strongly targeted on PC Instances, Coolers, and PSUs, providing an unlimited number of merchandise in all of those three classes. On the time of this evaluate, Cooler Grasp is providing an outworldish assortment of over 75 PC circumstances, 90 coolers, and 120 PSUs.
At this time we’re taking a look on the new XG Plus Platinum sequence, the newest energy provide household from prolific PC peripherals producer Cooler Grasp. Designed to supply a high quality PSU with an additional sprint of aptitude, the RGB fan (and RGB show) outfitted XG Plus Platinum is a PSU that is not fairly like the rest available on the market. The XG household ranges from 650 to 850 Watts, and as we speak we’re evaluating essentially the most highly effective unit within the sequence, the 850W XG850 Plus Platinum.

Packaging and Bundle
In comparison with a lot of the PC business today, Cooler Grasp is something however delicate with the design of their packaging. The art work is colourful and lavish, mixing geometrical patterns with photos and placing colours. In the end, what issues is that the unit is shipped in a really sturdy cardboard field and guarded by ample layers of packaging foam.
In addition to the standard AC energy cable, mounting screws, and a primary directions leaflet, Cooler Grasp additionally bundles various cable ties and some cables straps alongside with XG Plus Platinum.
The XG Plus Platinum is an all-modular design, permitting for the elimination of each DC energy cable, together with the 24-pin ATX connector. The entire cables are naked, ribbon-like, with black wires and black connectors. There isn’t any floppy connector or adapter.

The Cooler Grasp XG850 Plus Platinum PSU
Exterior Look
The chassis of the Cooler Grasp XG850 Plus Platinum PSU measures 86 mm × 150 mm × 160 mm (H × W × D), which is 20 mm deeper than a completely ATX compliant PSU. The overwhelming majority of contemporary PC circumstances account for the size of such high-performance PSU however the barely prolonged size can nonetheless be a compatibility downside with sure small footprint designs.
Cooler Grasp actually does need their newest PSU to face out from the gang, thus they went with a customized chassis with an embossed left aspect and an built-in fan finger guard. The embossed left aspect will likely be seen if the unit is positioned upside-down on the backside of a typical ATX case. The sticker with the unit’s certifications and specs covers a lot of the unit’s prime aspect.
A typical on/off change might be seen on the rear aspect of the unit, proper subsequent to the usual AC energy receptacle. The perimeter of Cooler Grasp’s emblem is printed subsequent to the change. About half of the entrance aspect of the unit is roofed by the connectors for the modular cables, with a primary legend printed above every connector. Right here we are able to additionally see a small connector for an inside USB cable that connects the PSU to the motherboard.
Whereas the PSU is turned off, the proper aspect of the unit is fully plain and, not like the metallic matte physique of the unit, it’s a shiny acrylic. There may be an RGB show hidden behind the acrylic, displaying the unit’s mannequin and three sensible figures – energy output, temperature, and fan RPM. The PSU must be put in with care as a result of the acrylic might be very simply scratched.
Nonetheless, the true downside right here is the orientation of the PSU itself – if customers choose a case that has the PSU compartment positioned at its backside, they’ll have to choose between showcasing the RGB fan or the aspect panel show. It’s also doubtless that the aspect panel show won’t be seen even when the PSU is positioned on the prime of the case, as many merchandise are designed in order to cover the PSU from direct eye contact.
Inner Design
Cooler Grasp has rebranded the 135 mm RGB fan that’s contained in the XG Plus Platinum unit. The fan has a hydro-dynamic sleeve bearing, which is each quiet and dependable. It has a most pace of 1800 RPM, which is so much for a fan of that dimension however, based on the graphs which can be printed on the field, the fan shouldn’t even attain 1000 RPM below regular ambient situations.
The within of the XG Plus Platinum is not like any platform that now we have encountered earlier than, with Cooler Grasp insisting that this PSU is fully of their very own design. Huizhou Xinhuiyuan Expertise would possibly form of disagree with that declare although. Nonetheless, now we have no particulars relating to the platform or how a lot Cooler Grasp’s engineers have been concerned on its design.
The filtering stage of the Cooler Grasp XG Plus Platinum PSU is textbook, with a complete of 4 Y capacitors, two X capacitors, and two filtering inductors. There is also a relay to bypass the NTC for elevated effectivity. The rectifying bridges are positioned on the primary heatsink of the first aspect’s inverting elements. The energetic APFC elements are hooked up to a separate heatsink throughout the aspect of the unit. Nippon Chemi-Con provides the big 450V/680μF APFC capacitor, which is positioned proper subsequent to a large filtering coil.
On the first aspect of the primary transformer, 4 transistors kind a full-bridge inversion topology, whereas 4 MOSFETs generate the 12V line on the secondary aspect of the transformer. It’s noteworthy that these 4 MOSFETs are the JMSL040SAG by JieJie Microelectronics, an organization whose merchandise we have by no means encountered earlier than. For the file, the MOSFETs on the first aspect (NCE65TF130) are offered by NCE Energy.
The three.3V and 5V traces are being generated through the DC-to-DC conversion circuits. This might have been a typical configuration for any unit with a excessive effectivity certification, with the distinctive attribute right here being that the conversion circuitry is positioned immediately onto the board with the cable connectors as an alternative of stand-alone PCBs. The entire secondary capacitors, electrolytic and polymer alike, are offered by Nippon Chemi-Con and Nichicon, each of that are extremely respected Japanese producers.
