The intermediate polar EX Hydrae was the subject of an extensive multiwavelength campaign in May-June 2000 built around a million second EUVE observation of the source. We present results of the EUV to hard X-ray component of the campaign derived from quasi-simultaneous EUVE, Chandra, and RXTE photometric and spectroscopic observations. Emphasis is given to the Chandra HETG spectrum, which shows strong emission lines of H-like O, H- and He-like Ne, Mg, Si, S, Ar, and Fe, and L-shell Fe. Line strengths are used to constrain the temperature and density of the emitting plasma, thereby constraining models of the accretion column.
