GAMDIAS is a well-known brand in the sphere of PC power and cooling components, focusing on innovatively crafting gaming hardware. This company was founded in 2012 in Taiwan. This Taiwanese manufacturer has gained international recognition for creating promising gaming components that fit within your budget. They have innovated new technology for their PC power and cooling components.
Today we will discuss the Kratos M1-750W PSU from GAMDIAS. This is not what you would call a flagship PSU, as it does not fall into the elite class of components; it is a low-quality PSU. It is more of a mid-range PSU that can help you afford it. Based on the build quality and specifications, it is a PSU that balances power and performance equally. The RGB lighting gives it the look of a gaming device. It currently costs $59 USD on Amazon. Everyone knows it was released in 2019, so it has been almost 5 years. You might wonder why we are writing about it. The reason is that it is still, to this day, a very popular gaming-looking PSU that remains within the budget of many gamers.

Box sections
In the box, we can see that it is well described regarding the PSU. All of the core features of the unit are printed on the front, with detailed information on the sides and rear of the box. The box itself is sturdy, but there is no additional packaging inside to protect the unit, which is merely wrapped in a nylon bag. This will help to carry the PSU and protect it from bumps due to consistent vibrations.
External Body
The Kratos M1-750W has a very unique body structure that is visible even with the lights off, featuring the company logo pattern on every side of the chassis, except for the top. The chassis measures 140 mm long, adhering to the ATX design guide recommendations, making it compatible with any ATX-compliant case.
GAMDIAS has placed their large stickers with electrical unit specifications written on them. Simple decorative stickers featuring the company and PSU series logos can be found covering most of the surface area on both sides of the chassis.
As we know, the Kratos M1-750 is not modular, so the side of the chassis is entirely plain. On the rear side, it has an on/off switch. There are two more switches: one that cycles through lighting patterns and another that toggles the unit’s “silent mode” on or off.
The main selling point of the Kratos M1-750W is its well-designed RGB lighting. Although the RGB LEDs are all inside the fan’s hub, they are fairly powerful and crisp, creating a strong visual effect. This PSU’s RGB is very colorful, and if you want to change or customize it, there is a switch for that, allowing customization if the unit is connected to a compatible motherboard or LED controller (5V Digital RGB Header).
Internal body
The Kratos M1-750W has a large fan made by PowerYear, a very well-known Chinese company. The PY-1225M12S is a 120 mm fan that features a sleeve bearing engine and has a maximum speed of 1800 RPM.
The OEM behind the GAMDIAS M1-750W is Andyson, an OEM that we encounter infrequently, but they typically do a fairly good job at designing mainstream and performance platforms. This unit is based on a modernization of a platform that has been around for quite some time. While it may be very simple by today’s standards, it is also a proven design with zero potential for surprises. Furthermore, the internal wiring and PCB layout are designed to minimize electrical noise and ripple, resulting in cleaner, more stable power delivery to your PC components.

On the secondary side, we can see the four power transistors that generate the DC rails: three form the 12V/5V lines, while an independent circuit handles the 3.3V line. This is the first unit in several years that we have seen without DC-to-DC circuitry on the secondary side. The 3.3V and 5V lines are generated via a group regulation scheme, with the controller monitoring the 12V and 5V lines as one.
This approach can become a significant problem in modern systems, where there is very little to no load on the 5V line, throwing the 5V rail well out of the design guide recommended limits. All of the secondary side capacitors are supplied by Jun Fu as well. Many users may be wary of Jun Fu as a supplier since we rarely see them inside PC PSUs, but Jun Fu is actually a very reliable capacitor manufacturer, better than what we typically expect to find in a low-cost design.”
