The Seasonic CORE GX ATX 3.1 PSU is a series of fully modular power supplies for home and office desktop PCs. Seasonic positions it as a balance between cost and performance, with 650W, 750W, 850W and 1000W models, 80 PLUS® Gold certification and a seven-year manufacturer’s warranty.
The range supports ATX 3.1, PCIe 5.1 and native 12V-2×6 connectivity. Each unit measures 140 × 150 × 86 mm, and detachable cables let a builder connect only what the PC needs.
Businesses handling personal data also need to consider how quickly they could recover access if a computer failed. Customer records, payroll files and unfinished client work may all depend on that machine. Choosing a PSU is one part of planning the hardware; it does not make a company GDPR compliant.
Imagine a small business that saves its current payroll file on one desktop. If that desktop fails on payday, the person handling wages may be unable to retrieve the information needed to pay employees. Nothing has to be stolen for the loss of access to cause problems.
Article 32 of the GDPR requires security measures appropriate to the risks of processing personal data. It includes maintaining the confidentiality, integrity, availability and resilience of processing systems, restoring access after an incident, and regularly checking whether safeguards work. The UK GDPR follows the same risk-based approach.
That gives hardware reliability a practical place in data protection planning. A correctly specified PSU supplies the computer’s components, but it cannot restore a damaged file, control who opens a customer database or keep the PC running through a prolonged mains outage.
The broader arrangements matter: protected backups, appropriate access controls, encryption where appropriate, and a recovery procedure someone has actually tested. An uninterruptible power supply, or UPS, may also be useful where a power cut would interrupt important work. Whether one is needed depends on the risk; GDPR does not prescribe a PSU brand or wattage.
The amount of power demanded by a graphics card can increase rapidly. ATX 3.1 addresses these short power excursions, while PCIe 5.1 compatibility covers modern GPU power connections.
Seasonic describes testing for excursions of up to 200% of rated power for 100 μs under specified conditions. That figure is a brief test condition. It does not double the PSU’s continuous output.
The updated 12V-2×6 connection uses longer power contacts and shorter signal contacts than the earlier design. Correct installation still matters.
These specifications concern electrical performance. They do not measure how securely a business stores personal data, and they cannot establish compliance with Article 32.
Builders may consider the CORE GX when they want modular cabling and current GPU connectors at the price point Seasonic targets. Designers and video editors can have similar hardware needs to gamers, although their machines may spend the working day rendering projects for clients.
Seasonic supplies native 12V-2×6 connectivity and a cable from the PSU’s 16-pin output to two 6+2-pin GPU connectors. This allows compatible older graphics cards to remain in use when the PSU is replaced. Check the cable inventory for the exact model before ordering.
If the computer also holds business records, keep access to those records restricted to authorised users. A family member using the machine for games should not automatically have access to client files. That separation is a matter of accounts, permissions and working practices.
Begin with the entire system, including the CPU, GPU, storage and cooling. Check the recommended PSU capacity from the graphics card manufacturer, then account for future upgrades.
Seasonic lists these outputs:
Its power calculator can help estimate demand. Compare the result with component requirements, connector availability and a sensible allowance for changes.
An office PC used for email and documents has different needs from a workstation with a demanding graphics card. Buying the largest unit does not provide extra protection for personal data. Once the electrical requirements are covered, consider whether the remaining budget would be better spent on backup and recovery arrangements.
The native cable connects a compatible graphics card directly to the PSU, with 16-pin connectors at both ends. Seasonic rates it for up to 600 W. The connection also supports compatible graphics cards with the earlier 12VHPWR power socket.
The cable rating does not represent the available GPU budget. The processor, drives and other components draw power from the PSU’s total capacity too.
Fully seat both plugs and check that their retaining latches engage. Leave sufficient clearance for the cable without tight bends or sideways force against either connector. Only use the supplied cables or replacements explicitly approved for that PSU model.
Document component replacements and investigate unexpected shutdowns on business machines. Repeated faults need attention before employees start accepting lost work as normal.
The CORE GX ATX 3.1 carries 80 PLUS® Gold certification. Seasonic quotes 90% efficiency at 50% load, consistent with the Gold threshold at 115 V. Efficiency varies with operating conditions; the rating does not mean every workload reaches that figure.
Cooling comes from a 120-mm hydrodynamic-bearing fan with S²FC control. Its speed responds to cooling demand. The OptiSink™ design uses a revised circuit-board layout, smaller MOSFETs and heatsink components to leave more room for airflow and heat dissipation.
Those features are relevant to a PC that spends hours running office applications, rendering video or processing data. They do not certify data security. Nor does a long warranty tell a business how quickly it could recover its files if the unit failed tomorrow.
The CORE GX line offers modular cables, modern GPU connections and several capacity options in a compact ATX format. The units are 140 mm deep, which can help when space inside the case is limited. Black and white versions are available, depending on local stock.
For an organisation processing personal data, the purchase should sit alongside a few practical questions. Where are the records stored? Who can retrieve a protected backup? How long would recovery take? Is there another authorised way to access essential information while the desktop is being repaired?
The Information Commissioner’s Office explains that recovery times depend on an organisation’s systems and the potential harm to people when their personal data becomes unavailable. There is no single recovery deadline for every business. Record the results of recovery tests and fix any weaknesses they reveal.
The Seasonic CORE GX ATX 3.1 offers modular cabling, current power connections and capacities from 650W to 1000W. Choose the model around the computer’s actual requirements and planned upgrades.
For GDPR purposes, its role is limited to the hardware supporting the system. Personal data also needs appropriate access protection, recoverable backups and tested procedures for dealing with failure. A sensible PSU choice fits within that work; it cannot complete it.
