Quick Answer
For a Boksburg remote-work rig pushing an RTX 4080 or RTX 4090, a 1000W 80+ Gold PSU is the right call — units like the Corsair RM1000x (R3,800) and Seasonic Focus GX-1000 (R3,600) are stocked at Evetech and include ATX 3.1 / 12V-2x6 connectors needed by current-gen NVIDIA cards.
Why 1000W and not 850W for a remote-work setup?
Remote workers running a GPU-accelerated workload — video encoding, large spreadsheets with GPU compute, or after-hours gaming — sustain higher wattage draw than a gaming-only machine that idles most of the day. An RTX 4090 alone can pull 480W peak; pair it with a Ryzen 9 7950X (170W TDP) and you're at 650W before storage, fans, or RAM. A 1000W PSU at 65% load runs cooler and quieter than an 850W unit at 85% load, extending component life.
80+ Gold vs Platinum: does it matter for a home office?
At 10–12 hours of daily use, the efficiency gap between 80+ Gold (87–90% efficient) and Platinum (90–94%) translates to a measurable electricity saving over a year. South Africa's electricity tariffs make this more meaningful than in some markets — Platinum is worth the R400–R600 premium if you run the machine 8+ hours a day. The Seasonic Focus PX-1000 (Platinum, ~R4,200) is the step-up option currently stocked at Evetech.
ATX 3.1 and 12V-2x6: what Boksburg builders need to know
RTX 4000-series and RTX 5000-series GPUs use the 12V-2x6 (previously called 12VHPWR) connector. Older PSUs shipped with adapters, but ATX 3.1-native units include a proper cable that handles the full 600W the connector is rated for without adapter risk. If you're buying a 1000W PSU to pair with an RTX 4080 or newer, confirm the PSU is ATX 3.1 native — not just adapter-compatible.
FAQ
Is 1000W overkill for a remote-work PC without a top-tier GPU?
For builds using an RTX 4070 or lower, 850W is sufficient — 1000W adds cost without a practical benefit. Step up to 1000W only if you have or plan to upgrade to an RTX 4080/4090 or a high-TDP workstation CPU like the Threadripper.
What makes a PSU good for 10+ hour remote-work sessions?
Semi-modular or fully-modular designs reduce cable clutter and improve airflow, which matters during extended sessions. A rated MTBF above 100,000 hours and a 10-year warranty (Seasonic) signal reliability for daily heavy loads.
How does Evetech handle PSU warranty in Boksburg?
Evetech offers manufacturer-backed warranties on all PSUs — Corsair and Seasonic both provide 10-year coverage on their top-tier 1000W units. Boksburg buyers can access warranty support via Evetech's national service process without visiting a physical store.
a 1000W PSU, run a quick wattage estimate using your GPU TDP + CPU TDP + 150W for the rest of the system. If the total is under 750W, save the money and buy an 850W Gold unit instead.
