The X-ray properties of Active Galactic Nuclei (AGNs) depend on their underlying physical parameters, particularly the accretion rate. We identified eight reverberation-mapped AGNs with some largest known rates without high-quality data. obtained new Chandra ACIS-S observations and nearly simultaneous optical spectrophotometry to investigate these extreme super-Eddington accreting black holes (SEAMBHs). combined our measurements those other AGNs, which have best-determined masses rates. trend steepening spectral slope between optical-UV, $\alpha_{\rm ox}$, increasing optical-UV luminosity, $L_{2500\r{A}}$, holds true for even most SEAMBHs. One SEAMBHs appears weak its perhaps due absorption associated orientation effects involving a slim disk thought be present in highly systems. correlation $\rm 2-8~ keV$ photon index rate also SEAMBHs, show indices reported AGNs.
