1000W PSU short-list for Krugersdorp should be shortlisted around the job it must do. South African buyers should compare wattage, efficiency, protection, and connector support, warranty path, and upgrade room before treating any pick as best.
For Krugersdorp builders, the 1000W PSU short-list starts with 80+ Gold ATX 3.1 units — Corsair RM1000x and Seasonic Focus GX-1000 sit around R2,500–R3,000 at Evetech and cover RTX 4080/4090 builds with 10-year warranties. The MSI MEG Ai1000P at ~R3,200 adds Platinum efficiency and native 12V-2x6 for the ultimate West Rand high-end build.
Krugersdorp sits in the West Rand, home to a growing PC gaming community. An RTX 4090 (450 W peak) paired with a Ryzen 9 7950X (170 W) draws ~680 W under full stress. Add fans, storage, and RGB and you hit ~720–750 W — 75% of a 1000W PSU's rated capacity, exactly in the 80+ Gold efficiency band. Choosing 850W here means running at 88–90% load: safe in theory, but leaves no headroom for GPU overclocking or a future GPU upgrade.
80+ Gold: 87–92% efficiency at 20–100% load. 80+ Platinum: 90–94%. 80+ Titanium: 92–96% but costs R800–R1,200 more than Gold — warranted only for 24/7 render farm or mining use, not typical gaming. For a Krugersdorp gamer running 4–6 hours daily, Platinum gives the best efficiency-to-cost ratio. The Cybenetics noise/efficiency database rates units independently from 80Plus — flagship Seasonic and Corsair units typically earn Lambda-A+ (ultra-quiet) noise ratings alongside their Platinum certification.
RTX 40-series GPUs and upcoming RTX 50-series models require the 12VHPWR or 12V-2x6 connector rated at 600 W continuous. ATX 3.1-compliant PSUs ship with this cable natively — no adapter needed. The original 8-pin-to-16-pin adapters used with early RTX 4090s caused documented connector failures; all new high-end GPU purchases should use a PSU with a native Gen 5 power cable.
R2,500–R3,000 covers quality 80+ Gold modular units from Corsair and Seasonic. R3,000–R3,500 steps into Platinum and ATX 3.1 territory. The extra R400–R600 for Platinum is recouped in electricity savings over a 5-year build cycle for a system running 6+ hours daily.
Yes — Krugersdorp is on the West Rand of Gauteng within Evetech's standard courier delivery zone. Standard delivery takes 1–2 business days; orders placed before noon typically ship same day. Large PSU boxes may require a signature on delivery.
Watch for instability under load: random shutdowns, USB device disconnections, system crashes during heavy GPU use, or 12V rail voltage below 11.8 V measured with HWInfo64. A PSU that crashes only when the GPU boosts hard is typically under-wattaged or has degraded capacitors — time to replace before it takes other components with it.
the 1000W PSU you're buying is ATX 3.1 or just ATX 3.0 — both support Gen 5 PCIe, but ATX 3.1 uses the improved 12V-2x6 connector with better retention and thermal performance than the original 12VHPWR on ATX 3.0 units.

Dead Pixel on Wi-Fi 7 Router is likely a display-path or source-title issue, so check the screen, cable, driver state, and related system symptoms before blaming the device itself.
Industry reports point to another roughly 10 percent Intel processor increase from 5 October, but Intel has not published a consumer price list confirming the scope. South African buyers should treat it as a risk signal, not a guaranteed Rand change.
Put the headphones in pairing mode, open Bluetooth and devices in Windows 11, then add the headset. If it fails, remove the old pairing and check charge, range and drivers.
Microsoft says upcoming Windows 11 work will target memory use on 8GB PCs and improve boot and sign-in responsiveness. There is no public release date or measured uplift yet.

For a stable RTX 5070 starting point, use 1440p, the High preset, Ray Tracing Medium and DLSS Balanced, then measure the base frame rate before adding Frame Generation. Path tracing is a separate showcase mode, not the default.
Microsoft's September release is reported to address 972 vulnerabilities, including two zero-days. The practical response is to back up, secure the BitLocker recovery key, prioritise exposed systems and verify business-critical apps after deployment.
Minecraft frame generation currently means an unofficial Fabric mod, not the same thing as official Bedrock RTX with DLSS upscaling. Check the game edition, loader, version, GPU path and base frame rate before installing anything.
HKC's 27-inch Shield 27Q560 runs QHD at 560Hz or 1280 x 720 at up to 1060Hz. The headline rate is specialised: resolution, sustained frame rate, ports and eventual South African support decide whether it is useful.
