DeepCool PX850G: 850W ATX 3.0 Ready Power Supply

PX850G DeepCool

Among the few seasoned professionals in the PC power and cooling component industry still in business today is DeepCool. After being established in 1996, the Chinese company first produced solely coolers and cooling accessories. However, it soon expanded into the PC case and power supply unit (PSU) markets. Even now, DeepCool’s primary concentration remains on PC power and cooling solutions; its most recent attempt at diversification is the creation of input devices and mousepads

Deepcool px850g review


The focus of today’s review is on DeepCool power supplies, particularly the PX850G 850W ATX 3.0 PSU, which is now the company’s best-selling power supply. The PX850G is designed to provide ATX 3.0 compatibility while striking a balance between affordability, dependability, and overall performance. Despite being built on a well-liked high-output platform, DeepCool oddly certified the PX850G for operation at temperatures as high as 40°C.

DeepCool PX850G packing

The packaging for the DeepCool PX850G 850W PSU is simple: a cardboard box with a little bit of flair added by a beautiful ribbon. The device is encased in a nylon pouch and has foam inserts all around it for added protection during transit. On the back, important details and a summary of the PSU’s capabilities are legibly displayed, providing prospective customers with a brief overview of what to anticipate from the device.

In addition to the standard mounting screws and AC power cable, DeepCool now includes four reusable cable straps and a jump-start adaptor for a small added cost. Additionally, a tiny packet with paperwork is there.

The totally modular design of this power supply unit sets it apart from others. It permits the detachment of all DC power lines, including the 24-pin ATX connector. From the connectors to the wires, the cables are all black. Since none of them have sleeves, the overall aesthetic is consistent.

ATX 3.0

The DeepCool PX850G is a new power supply unit (PSU) that meets the latest ATX 3.0 standard.

PX850G DeepCool features

  • 850 watts of power: This is plenty of power for even the most demanding gaming PCs.
  • 80+ Gold certified: This means that the PSU is efficient at delivering power to your components, which can save you money on your electricity bill.
  • Fully modular: This means that you only need to connect the cables that you need to your components, which can help to improve airflow in your case.
  • Fluid dynamic bearing (FDB) fan: This type of fan is quieter than a traditional fan, and it should help to keep your PC cool and quiet.
  • 10 year warranty: This is a long warranty for a PSU, which gives you peace of mind knowing that your investment is protected.
  • Overall, the DeepCool PX850G is a good option for a high-end gaming PC. It offers plenty of power, efficiency, and features, and it is backed by a long warranty.
  • Some reviewers note that the fan can be a little loud under heavy load, but overall, the noise levels are acceptable. Another potential downside is that the unit is a bit larger than some other PSUs on the market, so it may not be suitable for all cases. However, if you are looking for a powerful, efficient, and reliable PSU, the DeepCool PX850G is a good option to consider.

AtX 3.0 power supply

The DeepCool PX850G 850W PSU is contained in a chassis that is somewhat longer than the normal ATX proportions, measuring 86 mm × 150 mm × 160 mm (H × W × D). The power supply unit may be easily integrated into the majority of tower PC cases due to its size; the only exceptions are small and certain HTPC/Cubic PC case designs. The length of the device, in spite of its size, must be sacrificed in order to make room for its 135 mm cooling fan.

DeepCool has concentrated on the PX850G 850W PSU’s external design, which strikes a balance between practicality and style. The company’s emblem is subtly punched on both sides of the chassis of the power supply unit, which has a satin black finish. The integrated fan finger guard is unique from other round guards in that it has a square form. On the top of the PSU is an information sticker that lists its certifications and technical details.

The power switch and AC input jack are usually located on the back of the device, along with a push button that allows you to disable the hybrid fan mode and make the fan run continuously. The modular connectors are located on the front side and are easily identified by their plain white labels. One notable feature is the addition of a turquoise 12VHPWR connection, which adds a stylish touch while highlighting the unit’s adherence to the most recent ATX 3.0 standards.

Inside Out

An FDB engined Hong Hua HA13525H12SF-Z 135 mm fan is included with the DeepCool PX850G 850W PSU. These supporters are well-liked and renowned for their excellence. This specific fan cools an 850W unit at an astounding maximum speed of 2300 RPM, which is rather remarkable for a 135 mm fan.

Channel-Well Technologies (CWT), a prestigious OEM known for its proficiency in creating mid- to high-power output PC power supplies, is the manufacturer of the DeepCool PX850G 850W PSU. Several of the most well-known products ever made use of CWT’s platforms, solidifying the company’s longstanding reputation as a respected OEM.

There are no surprises in the DeepCool PX850G 850W PSU architecture, which is built on tried-and-true topologies. Four Y capacitors, two X capacitors, and two filtering inductors make up the filtering stage, which is marginally improved at the power supply’s input compared to the ATX design guide’s minimum baseline. Two rectifying bridges, each connected to a separate heatsink, are positioned after this.

The primary heatsink, which houses the active components around the edge of the PCB, occupies a large amount of space in the Active Power Factor Correction (APFC) circuits. A diode and two Infineon 6R125P6 MOSFETs make up the APFC transistors. The APFC is equipped with two sizable capacitors (a Nippon Chemi-Con 330 μF and a Rubycon 470 μF) as well as an enclosed filtering inductor.

A half-bridge LLC architecture is used in the DeepCool PX850G 850W PSU’s primary inversion stage. The two power transistors are placed on a sizable dedicated heatsink, a layout that is common in contemporary power supplies due to its dependability and low cost. Six Onsemi 5C430N transistors mounted on a vertical daughterboard make up the secondary conversion stage, which produces a single 12V output. On a different daughterboard, DC-to-DC conversion circuitry control the 3.3V and 5V outputs.

The DeepCool PX850G 850W PSU has many Nichicon polymer capacitors in addition to capacitors made by Nippon Chemi-Con and Rubycon on its secondary side. The PX850G is an all-Japanese product thanks to this combination of well-known Japanese manufacturers, which benefits the company’s marketing initiatives as well as the comfort of its customers.
