Quick Answer

EVGA exited the GPU and PSU market, but its 1000W power supply designs set a benchmark that competitors have since matched or exceeded. In South Africa in 2026, Corsair, Seasonic, be quiet!, and Thermaltake offer compelling 1000W alternatives that deliver equivalent or superior efficiency, modularity, and reliability.

EVGA 1000W PSUs: What They Were Known For

EVGA's SuperNOVA 1000W G6 and G7 series established a strong reputation for fully modular designs, Gold and Platinum 80 Plus efficiency ratings, and a ten-year warranty that few competitors matched at the time. The G7 1000W in particular earned praise for its quiet operation under load, tight voltage regulation, and compact depth that fit easily in most ATX cases.

EVGA's exit from the add-in card and PSU market in late 2022 meant these products are no longer manufactured. Stock has dried up globally, and finding new EVGA PSUs in South Africa in 2026 is effectively impossible through legitimate retail channels. The good news is that the alternatives available today are in many cases better than what EVGA offered.

Best Corsair 1000W PSU Alternatives in South Africa

Corsair is one of the most reliably stocked PSU brands in the South African market. The Corsair RM1000x SHIFT stands out as a premium alternative: it features a fully modular design with a unique side-mounted cable attachment that simplifies routing in most case layouts. It carries an 80 Plus Gold efficiency rating and operates passively (zero RPM fan mode) under 50% load, making it near-silent during office use and light gaming.

The standard Corsair RM1000x (non-SHIFT) is slightly more affordable and equally capable from an electrical standpoint, with tight rail regulation and a ten-year warranty. Both are available in South Africa at pricing in the R3,800 to R5,200 range depending on current Rand-to-USD movement.

For those wanting Platinum efficiency, the Corsair HX1000i adds digital monitoring via iCUE software, letting you track voltage rails, power draw, fan speed, and cumulative energy use. This level of insight is useful for builders who want to verify system health or optimise for loadshedding UPS runtime by understanding actual wattage under load.

Seasonic and be quiet! 1000W Options

Seasonic manufactures its own PSU internals and supplies OEM units to several other brands. The Seasonic Focus GX-1000 is a fully modular 80 Plus Gold unit with a hybrid fan mode and a ten-year warranty. It is exceptionally well-built and represents one of the best value propositions in the 1000W category available in SA.

be quiet! 's Straight Power 12 1000W and Dark Power 13 1000W are both strong options for builds where acoustics matter. The Dark Power 13 carries an 80 Plus Titanium rating, the highest efficiency tier available, which translates to lower heat output and longer UPS runtime during loadshedding. These brands are well-stocked through South African distribution and typically sit in the R3,500 to R5,500 range.

Thermaltake and Budget 1000W Alternatives

Thermaltake's Toughpower GF3 1000W is a fully modular ATX 3.0-ready option with a 10-year warranty that undercuts most Corsair and Seasonic equivalents in price. It supports PCIe 5.0 16-pin connectors natively, future-proofing the PSU for high-power GPU upgrades. For builders pairing a 1000W PSU with an RTX 5090 or RX 9070 XT, native connector support eliminates the need for daisy-chaining adapters.

Budget-oriented builders can also consider Silverstone or Antec 1000W units in the R2,500 to R3,200 range, which sacrifice some warranty length and efficiency tier but remain reliable for standard gaming builds.

Frequently Asked Questions

Can I still buy an EVGA 1000W PSU in South Africa? No. EVGA exited the PSU market and new stock is not available through legitimate South African retail channels. Pre-owned units exist but come without warranty, making alternatives a safer investment.

Is 1000W enough for high-end GPU builds in 2026? Yes. A 1000W PSU comfortably handles builds with RTX 5080, RTX 5090, RX 9070 XT, or comparable GPUs paired with high-end CPUs. Most flagship single-GPU systems draw 600 to 800W under full load, leaving meaningful headroom.

Does PSU efficiency affect UPS runtime during loadshedding? Yes. A Platinum-rated PSU wastes less power as heat compared to a Gold or Bronze unit. For the same system load, a more efficient PSU draws fewer watts from the wall, extending the time your UPS can sustain your system during a loadshedding event.

What warranty should I look for in a 1000W PSU? Seven years is the minimum for a quality PSU at this price point. The best options, including Corsair RM, Seasonic Focus, and be quiet! Dark Power units, offer ten-year warranties, reflecting confidence in their components.
