Pros & Cons

Pros

  • ✓ Native 12V-2x6 (12+4 pin) cable delivers up to 600W to a single GPU
  • ✓ ATX 3.1 and PCIe 5.1 compliant, ready for RTX 40 series and next-gen cards
  • ✓ Japanese capacitors with rated ripple noise under 30mV
  • ✓ ECO mode keeps the 140mm FDB fan off below 40% load
  • ✓ Fully modular soft flat braided cables make routing and airflow cleaner

Cons

  • ✗ No specific Cybenetics efficiency or noise tier stated in the listing
  • ✗ Over 90% efficiency is quoted only at typical load, not the full range
  • ✗ Warranty length not stated in the listing; confirm with SAMA before buying
  • ✗ Fan spins up above 40% load, so sustained gaming loads are not silent

SpecPicks Verdict

SpecPicks scored SAMA G1000 1000W ATX 3.1 Fully Modular Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. SAMA's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
