A full grid of every 1000W supply on local shelves helps you cut through marketing and compare on the metrics that actually matter for a high-watt build: efficiency tier, connector standard, warranty, and cable type.
Quick Answer
For a 1000W build, the decisive specs are an 80 Plus Gold or Platinum rating, an ATX 3.1 rating with a native 12V-2x6 connector, and at least a 7-year warranty. Expect SA pricing from roughly R2,800 for Gold units up to R5,500 for Platinum fully modular models.
Reading The 1000W Feature Grid
Group the field by efficiency first. Gold units cover most needs and offer the best value; Platinum and Titanium cut heat and running cost for buyers who run heavy loads daily. Then filter by connector: a native 16-pin cable rated for 600W is essential for current high-end GPUs.
Warranty length is a strong proxy for build quality at this tier. A 10-year warranty signals premium internals, while a 5-year unit suggests a budget platform.
Value Tiers For SA Buyers
Around R2,800 to R3,500 you find solid Gold units suited to a single high-end GPU. The R4,000 to R5,500 band brings Platinum efficiency, quieter fans, and longer warranties for buyers planning years of heavy use. Spending past that rarely improves a single-GPU gaming rig.
FAQ
Which efficiency tier gives the best value at 1000W?
80 Plus Gold offers the strongest balance of price and efficiency for most builds. Platinum pays back only with sustained heavy daily loads.
How important is the warranty length?
Very. A 7 to 10-year warranty usually marks a higher-grade platform and protects an expensive component over a long build life.
Do all 1000W units include a native 16-pin cable?
No. Older ATX 3.0 stock may ship with adapters. Confirm a native 12V-2x6 cable before buying for a current GPU.
1000W list by warranty length first; it reliably separates premium platforms from budget rebadges at this wattage.
