Quick Answer
Pretoria East remote workers running RTX 4080 or RTX 4090 builds should target the Corsair RM1000x (R3,800) or the Seasonic Focus GX-1000 (R3,600) — both are 80+ Gold, fully modular, and include native ATX 3.1 / 12V-2x6 cables for current-gen NVIDIA GPUs.
Tier breakdown: Gold vs Platinum for a Pretoria East home office
The 80+ certification tier affects daily running costs. An 80+ Gold PSU (87–90% efficient) running 10 hours a day at 600W load wastes roughly 60–70W as heat. An 80+ Platinum unit (90–94%) cuts that waste to 36–42W. At South Africa's current electricity tariffs, that saves a meaningful amount over a year on a full-time remote setup. The Seasonic Focus PX-1000 (Platinum, ~R4,200) and Corsair HX1000i (Platinum, ~R4,600) are both stocked at Evetech and represent the tier-up option.
ATX 3.1 and 12V-2x6: what changes for 2024+ builds
All RTX 4000-series and RTX 5000-series NVIDIA cards use the 16-pin 12V-2x6 connector. PSUs without native ATX 3.1 support ship an 8-to-16-pin adapter — functional for moderate loads, but the adapter has caused connector damage at sustained RTX 4090-level wattage (480W+). For a 1000W Pretoria East build, confirm the PSU lists ATX 3.1 native support, not adapter compatibility only.
Cable management for a home-office desk
Fully modular PSUs let you route only the cables you use, keeping the interior clean and airflow unobstructed during 10-hour remote sessions. Semi-modular units (like the Corsair CX1000F) are cheaper but leave the 24-pin ATX and EPS12V cables permanently attached. For a clean desk-visible build or a small-form-factor shelf, full modularity is worth the R200–R400 premium.
FAQ
What size PSU does an RTX 4090 actually need in Pretoria East?
An RTX 4090 has a 450W TDP but can spike to 480W in short bursts. Paired with a Ryzen 9 7900X or Core i9-13900K, total system draw peaks above 700W — a 1000W unit keeps that load at 70% or below for optimal efficiency and noise.
Does a higher-wattage PSU draw more standby electricity?
No — a PSU only draws what the connected components demand. A 1000W unit running a 400W system draws roughly 400W (adjusted for efficiency), not 1000W. Idle/standby draw is typically under 1W regardless of rated wattage.
How does Evetech handle PSU returns and warranty from Pretoria East?
Evetech provides manufacturer-backed warranty on all PSUs, handled nationally. Corsair and Seasonic offer 10-year warranties on flagship units. Returns and RMAs are processed via Evetech's support portal without requiring a physical drop-off.
1000W, total your GPU TDP + CPU TDP + 150W overhead. Most RTX 4070 Ti builds land under 650W total — in that case an 850W Gold unit saves R600 with no real downside.
