General Information

DUT Information

BrandGamemax
製造商 (OEM)Sohoo
SeriesGX
Model NumberGX1050
Serial Number
DUT NotesNo -12V Rail, despite the label saying it has one. During OCP testing under normal and cold conditions, the +12V rail reached 127A (>145% load) without shutting down. This forces us to not provide an ATX v3.1 compliance.
