I've had experience using the Fisher & Paykel Simplus at high pressure and find it works well for me. It might be a combination of my face shape as well as the mask but it's great. I found it online after speaking with some lovely staff at a Friendlies Independent Living store... they told me it was cheaper online than instore. https://cpap.friendlies.com.au/fisher-paykel-simplus-full-face-mask-large.html I'd suggest if you have questions to give them a call for advice - they're super helpful and I've been getting sleep results since using the Simplus.
