We present the hard X-ray time-averaged spectrum of the intermediate polar V709 Cas observed with INTEGRAL. We performed the observation using data from the IBIS/ISGRI instrument in the 20-100keV energy band and from JEM-X at lower energy (5-20keV). Using different multi-temperature and density X-ray post-shock models we measured an improved post-shock temperature of ∼40keV and estimated the V709 Cas mass to be 0.82^+0.12_–0.25M_☉. We compare the resulting spectral parameters with previously reported BeppoSAX and RXTE observations.
