asus prime b250-plus
Technical Specifications
Technical Summary
The ASUS PRIME B250-PLUS motherboard is documented in a repair guide that includes standard appearance, block diagram, power flow, power on sequence, timing diagrams for G3 to S5 and S5 to S0/M0, frequency flow, socket reflow profile, and lead-free BGA rework thermal profiles. Voltage measurement points are provided for key rails including +3VSB_ATX at station PU4001, +5VSB at PQ4002, VCORE at PL1010, +3VSB at OQ760, VDDQ at PL2011, +5VSB_DUAL at PQ4501, and +12V, +5V, and +3V at EATXPWR and K1L51. Signal measurement points cover sequences from S_RTCRST# through O_X1_RST#, with diode resistance values listed for each test point.
