I do Costco eggs right out of the fridge with 1 cup of water, eggs on a trivet, for 4 minutes at high pressure, 4 minutes release then 4 (or more) minutes in an ice bath. (The 4-4-4 method.) They come out perfect. I have done this in both 8 and 3 qt models.
ETA: Oops, I thought you meant hard-boiled, not poached.
