ATX Computer Power Supplies
Models in the Power Supply PC category that use the ATX (Advanced Technology eXtended) standard are at the heart of nearly every modern desktop computer. Their main job is to convert alternating current (AC) into low-voltage direct current (DC) that powers the processor, graphics card, and motherboard. Introduced by Intel, the ATX standard has evolved over the decades to keep pace with the growing power demands of modern components.
A good-quality ATX power supply today offers not only the right amount of power, but above all a range of protections, including:
- OVP (Over Voltage Protection) – protection against excessive voltage;
- OCP (Over Current Protection) – protection against regulator overload;
- SCP (Short Circuit Protection) – short-circuit protection.
ENDORFY ATX power supplies focus on high energy efficiency, which translates into lower electricity bills and less heat output. This allows the fans to run more slowly, so gamers can enjoy quiet operation even during intense sessions in the most demanding titles.
ENDORFY offers power supplies with a range of wattages. We provide 350W models for the least demanding builds, as well as very powerful 750W power supplies and 1000W power supplies for the most demanding gaming PCs.
ATX Power Supply Dimensions
Although the ATX standard defines a fixed width and height, the final overall dimensions of an ATX power supply depend on the design of the specific model. This is a key parameter to consider when choosing a case. Standard ATX power supply dimensions are 150 mm wide and 86 mm high, while length typically ranges from 140 mm to 180 mm (and can be even greater for extremely powerful units).
Most midi tower and full tower cases can easily accommodate ATX power supplies 140–160 mm long. However, if you're planning a build in a smaller case or using an extensive liquid-cooling system at the bottom of the chassis, be sure to check the maximum supported power supply length in the case specifications—it should be clearly stated by the manufacturer.
It's also worth keeping cable space in mind—a modular ATX power supply lets you disconnect unused cable bundles, which significantly simplifies cable management and improves airflow inside the computer.
FAQ
-
What are the key characteristics of ATX power supplies?
Every ATX computer power supply is characterized primarily by a standardized mechanical and electrical design. These models use standard connectors, including a 24-pin motherboard connector, EPS connectors for the processor, and PCIe connectors for graphics cards. Another defining feature is the ability to be switched on and off remotely by a signal from the motherboard, allowing the operating system to fully control power.
-
How do you choose the right ATX power supply wattage for a computer?
An ATX computer power supply should meet the total power requirements of all components, with particular attention to the graphics card and processor. To calculate the required power, you can use online power supply calculators or add up the TDP values of all components. It's worth adding 20–30% to the result to leave some headroom.
-
Do ATX power supplies fit every case?
No. ATX power supplies fit ATX cases (midi tower, full tower) and some larger micro-ATX cases. However, they will not fit in very small SFF (Small Form Factor) or mini-ITX cases that require smaller standards such as SFX or TFX. Before buying, always check which power supply standard your case supports.
-
What efficiency certifications do ATX power supplies have?
Power supply efficiency is most commonly confirmed by 80 PLUS certification. It indicates how much of the energy drawn from the wall outlet is actually delivered to the components and how much is dissipated as heat. The available tiers are: 80 PLUS (White/Standard), 80 PLUS Bronze, 80 PLUS Silver, 80 PLUS Gold (most commonly chosen by informed users), 80 PLUS Platinum, and 80 PLUS Titanium. The higher the certification, the better the quality of the internal components, the lower the electricity bills, and the quieter the device operates. For example, a Gold-certified power supply must achieve at least 90% efficiency at 50% load.
