Quick Answer

Benoni builders should shortlist 1000W PSUs from R2,200 at Evetech — the right capacity tier for RTX 4080, RTX 4090, and high-core-count CPU builds. Corsair RM1000x and Seasonic Focus GX-1000 are benchmarks at this wattage, both 80+ Gold with 10-year warranties and full modular cabling.

Who Needs a 1000W PSU in Benoni?

Any Benoni builder pairing an RTX 4080 (320 W TDP) or RTX 4090 (450 W TDP) with a CPU above 125 W needs 1000W to stay safely under 80% rated load during simultaneous CPU+GPU stress. This build profile is common among gamers who also run video rendering, AI workloads, or streaming from the same machine. At 1000W, a Ryzen 9 7950X (170 W) + RTX 4090 (450 W) build pulls ~680 W peak — 68% load, in the efficiency sweet spot.

80+ Gold vs Platinum: Which to Choose

80+ Gold achieves 87–92% efficiency at 20–100% load. 80+ Platinum hits 90–94%. The real-world difference at SA electricity rates (approximately R2.50/kWh) for a system running 6 hours daily: Platinum saves roughly R130–R200 per year over Gold. Over a 10-year PSU lifespan, that's R1,300–R2,000 in electricity savings — competitive with the R400–R600 price premium. For heavy daily use, Platinum pays for itself.

ATX 3.1 and the 12V-2x6 Connector

Current RTX 40-series GPUs use a 16-pin 12VHPWR or 12V-2x6 power connector rated at 600 W continuous. ATX 3.1-compliant 1000W PSUs include this cable natively. Avoid using adapter cables from an 8-pin PCIe bundle to this connector — several high-profile cases of connector overheating occurred with early RTX 4090 adapters. Native cable is safer and ATX 3.1 compliance confirms the PSU meets the current standard.

FAQ

What's in stock for 1000W PSUs at Evetech for Benoni delivery?

Evetech typically stocks Corsair RM1000x, Seasonic Focus GX-1000, and MSI MEG Ai1000P among 1000W options. Availability varies — check the current listings on Evetech's website. Benoni is on the East Rand in Gauteng. For current delivery times and costs, see our delivery page.

Is a 1000W PSU worth it over an 850W for an RTX 4080 build?

An RTX 4080 build with a mid-range CPU draws 500–550 W peak, putting it near 65% load on an 850W PSU — acceptable. However, the R200–R400 step to 1000W buys headroom for a future GPU upgrade without replacing the PSU. If budget allows, 1000W is the smarter long-term investment.

Are 1000W PSUs bigger than 750W units?

Often yes — higher-wattage units typically run 160–180 mm deep versus 140–150 mm for 750W models. Confirm your case's PSU bay depth before ordering a 1000W unit, particularly in compact mid-towers where clearance is tight.

TIP

between two similarly-priced 1000W PSUs, pick the one with the longer warranty — a 10-year warranty versus 7-year reflects better component quality and gives you peace of mind for the full platform lifecycle.
