Seasonic Focus GX-1000 ATX 3.1
The Seasonic Focus GX-1000 computer power supply provides gaming and work setups with a stable 1000W output. Its design meets ATX 3.1 and PCIe 5.1 standards, which is key for supporting hardware components with high energy demands. Its power conversion efficiency is confirmed by the 80 PLUS Gold certification, which reduces energy loss and residual heat generation. The fully modular cabling contributes to a clean cable installationand better airflow inside the case. A 135mm fan handles cooling, while OptiSink Design technology further optimises heat dissipation. Thanks to its compact 140mm depth, it's also easy to install in most cases.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the computer's components. It is a good idea to use a web calculator to determine the optimal power output based on your chosen components.
ATX 3.1 and PCIe 5.1 standards
Full compatibility with ATX 3.1 and PCIe 5.1 specifications prepares the power supply for the high power spikes generated by powerful graphics cards and processors. It includes a native 12V-2x6 connector for connecting graphics cards without needing adaptors. This ensures the power supply delivers energy reliably and efficiently, even under sudden and extreme loads.
Seasonic Focus GX-1000 cooling
The patented Digital Hybrid Fan Control technology manages the 135mm fan in three stages. Under low load, the fan remains completely off, and the power supply operates passively. As the temperature rises, it activates a silent mode with low RPM. Only under high load does the control unit switch the fan to cooling mode to maintain optimal operating conditions.
OptiSink Design technology
OptiSink Design technology enhances the internal layout of the power supply for more effective cooling. A newly designed printed circuit board (PCB) combined with smaller MOSFET transistors and heatsinks increases the internal space. This solution improves airflow and the dissipationof residual heat from key components, such as diodes. The result is a lower operating temperature, which contributes to greater reliability and a longer component lifespan.
Compact design of the Seasonic Focus GX-1000
With a depth of just 140mm, this power supply is one of the more compact ATX devices. Its smaller size simplifies installation in computer cases, including smaller form factors with limited space for cable routing. Despite its smaller physical dimensions,the power supply retains its full 1000W output and all its advanced features. The extra free space inside the case also promotes better air circulation and contributes to lower temperatures for the entire build.
Modular cabling of the Seasonic Focus GX-1000
Thanks to its fully modular cabling system, you only need to connect the cables your build actually requires to the Seasonic Focus GX-1000 computer power supply. Reducing excess wires not only makes cable management easier and simplifies assembly, but also minimises obstructions to airflow, which helps to cool the entire system more efficiently.
Comprehensive protection suite
The power supply integrates a complete suite of electrical protections for the safe operation of connected components. The OVP (Over Voltage Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), and OPP (Over Power Protection) circuits monitor electrical values. The protection is complemented by an SCP circuit against short circuits and OTP, which monitors the power supply's temperature and shuts it down in case of overheating.

80 Plus certification in the European market
The 80 Plus certification was created to objectively assess the efficiency of PC power supplies, giving users a simple and clear way to compare different models. On the European market (which uses a 230V mains voltage), there are six levels of 80 Plus certification, each with specific requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
Clearly specifies the maximum computing power performance in watts (W). The most common values include 400 W but some gaming computers have a 1000 W or more.
The physical dimensions of the source determine its next deployment. For classical computers there is the type ATX, but some miniature cases require a source with smaller dimensions (TFX).
This is a list of other functional equipment of the resource. Desired parameters are primarily detachable cables, thermal fan speed control or completely passive cooling.

Je tento zdroj naozaj vo verzii ATX 3.1? V popise ma 3.0, no v parametroch 3.1, avsak pisete, ze GPU kabel je 12PWHR, pricom v 3.1 verzii by mal byt kabel oznacovany ako 12V6+6. Ako je to teda? Planujete naskladnovat aj 3.1 modely silnejsie ako 1000W / s lepsou ucinnostou ako Gold?
