Pros & Cons

Pros

  • ✓ Native PCIe 5.1 12V-2x6 cable delivers up to 600W to a single modern GPU
  • ✓ 80 PLUS Platinum certification at 850W output
  • ✓ Matcha dual-color H++ connector shows green until fully seated
  • ✓ Etched flat full-modular cables route more flexibly behind the tray
  • ✓ 140mm case length fits compact ATX and SFF-adjacent builds

Cons

  • ✗ 850W ceiling is tight for a 12V-2x6 GPU paired with a high-draw CPU
