I'm not sure if I misunderstood if this was a question but here you go:
With 230VAC RMS line voltage the rectified DC voltage will be: √2 x 230VAC = 325VDC
The boosted (PFC) voltage depends entirely on how the PFC controller works so that can't be calculated without tracing the whole circuit out and reading datasheets.
P.S: The PFC circuit is normally off when the unit is in standby mode.
