We present a 100 kHz optical parametric chirped pulse amplifier (OPCPA) developed for strong-field attosecond physics and soft-X-ray transient absorption experiments. The system relies on noncollinear potassium titanyl arsenate (KTA) booster OPCPAs and is pumped by a 240 W, 1.1 ps Yb:YAG Innoslab chirped pulse laser amplifier. Two optically synchronized infrared output beams are simultaneously available: a 430 {\mu}J, 51 fs, carrier-envelope phase (CEP) stable beam at 1.55 {\mu}m and an angular-dispersion-compensated, 125 {\mu}J, 73 fs beam at 3.1 {\mu}m.
