ATX 600W vs TFX 300W Comparison
Form factor and fit
The ESGAMING 600W Non-Modular ATX Power Supply uses a standard ATX form factor. Its dimensions are 5.51 inches in length, 3.15 inches in width, and 5.91 inches in height. This size fits most standard desktop cases. The ESGAMING 300W TFX Power Supply uses a Flex ATX form factor. Its dimensions are 6.69 inches in length, 3.35 inches in width, and 2.56 inches in height. This smaller profile is designed for ultra-thin desktops, mini ITX models, and small enterprise servers. You must choose the form factor that matches your case. Standard cases require the ATX unit. Small cases require the TFX unit.
Wattage output
Power capacity is a major difference between these two units. The ESGAMING 600W Non-Modular ATX Power Supply provides 600 watts of total power. This higher output supports more demanding components and multiple drives. The ESGAMING 300W TFX Power Supply provides 300 watts of total power. This lower output is suitable for basic systems, NAS units, or low-power builds. If you need to run high-end graphics cards or many peripherals, the 600W unit is necessary. The 300W unit is limited to lighter loads. Your system requirements will dictate which wattage level is sufficient for your needs.
Cooling fan size
Both units use forced air ventilation but differ in fan size. The ESGAMING 600W Non-Modular ATX Power Supply includes a 120mm cooling fan. This larger fan can move more air at lower speeds, potentially reducing noise. The ESGAMING 300W TFX Power Supply includes an 80mm fan. This smaller fan is required to fit the compact TFX form factor. A larger fan often provides better thermal performance and quieter operation under load. The 120mm fan in the ATX unit offers a cooling advantage over the 80mm fan in the TFX unit. Both fans are auto-thermally controlled to adjust speed based on temperature.
Modularity
Cable management differs significantly between these two models. The ESGAMING 600W Non-Modular ATX Power Supply is non-modular. This means all cables are permanently attached to the unit. You must manage the length and routing of unused cables inside your case. The ESGAMING 300W TFX Power Supply is also non-modular. All cables are fixed to the unit. Neither product offers modular or semi-modular designs. You will need to plan your cable routing carefully for both options. The fixed cables can sometimes make building in tight spaces more challenging. This is a tie in terms of flexibility, as neither allows you to remove unused cables.
Connectors and compatibility
Both supplies provide essential connectors for standard components. The ESGAMING 600W Non-Modular ATX Power Supply includes a 24-pin main connector, a 4+4-pin CPU connector, two 6+2-pin PCIe connectors, four SATA connectors, four PATA connectors, and one FDD connector. The ESGAMING 300W TFX Power Supply includes a 24-pin main connector and a 4+4-pin CPU connector. The data does not list PCIe, SATA, or PATA connectors for the TFX unit. The ATX unit offers more expansion options for drives and graphics cards. The TFX unit is limited to basic motherboard and CPU power.
Which PSU fits your build
Standard desktop builders needing power
Choose this unit if you are building a standard ATX desktop. The 600W output provides ample headroom for modern components. It includes a 120mm fan for cooling and offers multiple PCIe connectors. The non-modular design keeps costs down while delivering reliable performance for typical gaming or workstation setups.
Mini ITX or NAS users
Select this model for small form factor cases. The TFX form factor fits tight spaces in mini ITX builds or NAS enclosures. It delivers 300W of power, which is sufficient for low-power systems. The compact 80mm fan and slim profile ensure it fits where standard ATX units simply will not.
Users prioritizing quiet operation
Opt for the ATX version if noise matters. The larger 120mm fan can spin slower than the 80mm fan in the TFX unit to move the same amount of air. This results in quieter operation under load. The auto-thermal control adjusts speed based on temperature, keeping your build peaceful during idle or heavy use.

Frequently asked questions
Can the ESGAMING 600W ATX fit in a small case?
No, it likely will not. The ESGAMING 600W Non-Modular ATX Power Supply measures 5.51 inches in length, 3.15 inches in width, and 5.91 inches in height. This standard ATX footprint requires a full-sized or mid-tower case. You need ample internal space to accommodate these dimensions comfortably during installation.
Is the TFX 300W suitable for a standard desktop PC?
It is not ideal for most standard desktops. The ESGAMING 300W TFX Power Supply is designed for compact mini ITX and NAS builds. Its 300W output limit may restrict high-performance components. If you are building a standard ATX desktop, the 600W ATX unit provides more reliable power delivery and headroom.
What is the main difference in size between these two units?
The primary difference is their form factor and physical dimensions. The 600W ATX model is larger, measuring 5.91 inches in height. The 300W TFX model is shorter at 2.56 inches in height but slightly longer at 6.69 inches. Choose the ATX for standard cases and the TFX for tight spaces.
Does the ESGAMING 600W support standard ATX motherboards?
Yes, it is built for standard compatibility. The ESGAMING 600W Non-Modular ATX Power Supply uses the standard ATX form factor. This ensures it fits standard desktop builds where space is not a constraint. It prioritizes straightforward installation and reliable power delivery for typical desktop configurations.
Which power supply is better for a NAS build?
The ESGAMING 300W TFX Power Supply is the better choice. It is specifically suited for compact builds like NAS systems. Its small footprint and voltage flexibility make it ideal for these specialized applications. The 600W ATX unit is too large and offers more power than a typical NAS requires.
Are both power supplies non-modular?
The data confirms the 600W ATX is non-modular. The ESGAMING 600W Non-Modular ATX Power Supply features fixed cables. The description for the 300W TFX unit does not specify its modularity. You should assume the TFX model may have different cable configurations, but specific details are not provided in the current data.
Can I use the TFX 300W in a full tower case?
You can, but it is not necessary. The ESGAMING 300W TFX Power Supply is designed for compact mini ITX and NAS builds. While it might physically fit in a larger case, its 300W output is limited. For a full tower, the 600W ATX unit provides more appropriate power and standard form factor compatibility.
