Seasonic VERTEX GX ATX 3.1 Spec and Price in Canada
The gold VERTEX: the same 160mm ATX 3.1 chassis, the same 135mm fluid-dynamic-bearing fan and hybrid fan control as the platinum PX, at 90% efficiency at half load instead of 92%. It ships at 750W, 850W, 1000W and 1200W with a 12V-2x6 cable included, and carries Seasonic's twelve-year warranty. For most single-GPU builds this is the VERTEX to buy — the PX's extra efficiency point rarely pays for itself over the life of the machine.
Prices exclude GST/HST.

What owners and reviewers say
Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Uses high-temperature-rated Japanese capacitors, deliberately over-specified to sustain above its rating.
- Supports the latest power standards with a native high-power connector, and load regulation is among the tightest tested.
Commonly criticised
- Quality comes at a price, and it is hard to find in stock.
