GIGABYTE AORUS P850W Power Supply Review

It has been over two years since we did our one and only power supply review with the GIGABYTE namesake. GIGABYTE is once again stepping up to the plate, this time with an AORUS branded unit, which tells us it is supposed to be "POWER OVERWHELMING." This unit comes from a relatively unknown OEM, so how will this AORUS stack up?


Today, GIGABYTE (GIGA-BYTE Technology Co., Ltd) is up for a trip through our power supply testing program. As a company, GIGABYTE has a longer history than many other companies in the enthusiast DIY realm having been founded in 1986. While GIGABYTE's primary focus has been motherboards and graphics cards, it has branched out in to laptop/tablet design, PC design, chassis, and even a few power supplies. The early power supplies in these lines were not something we saw much of but, hopefully, going forward we will see more and more from GIGABYTE in this realm. Today, we are looking at our second GIGABYTE branded power supply. This is from their new AORUS line and the AORUS P850W (GP-AP850GM or AP850GM) we are looking at today is produced by MEIC.

Xiamen Metrotec Electronic Industry Co., Ltd. (MEIC) was founded a few short years ago in 2007. To date, their products have been almost exclusively in the power adapter realm and not the SMPS realm let alone the enthusiast power supply realm. Obviously, this makes them currently only a minor power supply OEM that is not nearly as well known to users as some other OEMs as its core business focus has been outside of the desktop market. However, with GIGABYTE picking MEIC up as their contract manufacturer, perhaps we will start to see more of them in the future.

But Does It Have A Good Aura?

The GIGABYTE AORUS P850W is just the second power supply we have seen from GIGABYTE. From that perspective, we do not have a great idea of what to expect from this unit. However, the first unit we saw was the XP1200M and that unit was definitely a competitive product in a very difficult market segment. So, while the examples we have from GIGABYTE are limited, the limited examples we have seen give us hope that today's AORUS P850W will be good as well. That said, there is one last small wrinkle to this and that is the OEM on this unit, MEIC, is a relatively unknown manufacturer in this segment (unlike Enhance who produced the XP1200M). That definitely keeps a bit of mystery in the air for today's AORUS P850W. Before moving on to see how a small, but good, pedigree mixes with an unknown OEM, let's see what GIGABYTE has to say about this unit and how it is supposed to separate itself from so many other products:

Taipei, Taiwan, 16th July, 2018 - GIGABYTE, the world's leading premium hardware brand, today announced the release of AORUS P850W and P750W, the first PC power supplies (PSUs) from its premium AORUS brand. The new P850W and P750W bring up 80 PLUS Gold power efficiency silent operation, as well as modular customization, and enhanced durability for gaming enthusiasts, especially those with multiple-GPU builds focused on VR gaming.

80 PLUS Gold certified, the AORUS PSU delivers superior electrical performance at a minimum of 90% energy efficiency, ensuring power waste is kept at a minimum. With less heat and reduced fan noise, gamers with AORUS PSUs can enjoy cool and quiet gaming environment. With optimal support for Intel processors, the power supply is also ideal for achieving reduced energy.

Using 100% Japanese capacitors and premium internal components throughout the design, the AORUS PSU provides users with extended product reliability and lifespan. The single +12V rail ensures the best power output with stability for the hardware, making this power supply ideal for overclocking. The 135mm temperature-controlled smart fan is automatically adjusted according to the actual power usage so even when the power usage is lower than 20%, the fan will automatically activate the stop function to ensure energy saving and stable power supply. The fan uses an ultra-durable double ball bearing design, which offers prolonged product life over 50,000 hours.

AORUS P850W and P750W power supplies not only have built-in OVP/OPP/SCP/UVP/OCP/OTP circuit protection designs but have also undergone rigorous testing of various safety regulations in various countries. AORUS PSUs provide the most stable and abundant supply of power for the system and protect various devices inside the computer to ensure the users have a more stable and high quality experience.

AORUS P850W and P750W both come with a 10 Year warranty, and will be available soon on the market

With that out of the way, let's move on and see what we have to look forward to when we purchase the GIGABYTE AORUS P850W power supply in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
