Cześć, dostałem płytę, która nie startuje (stan wizualny - ideał), wykryłem zwarcie do masy na linii 3VSB, ale nie mam jak wykonać próby zwarciowej. Dysponuję jedynie schematem PDF. Możecie dać wskazówki gdzie szukać tego zwarcia? Może ktoś dysponuje plikiem CAD do Boardview dla tej płyty ?

Boardview do tej płyty jest na forum: schemat-msi-mag-z490-tomahawk-ms-7c80-t64129.html

Niestety, bez próby zwarciowej się nie obejdzie - elementów, podłączonych do linii 3VSB jest zwyczajnie zbyt dużo, aby "bawić się" w ich wylutowywanie po kolei. Zwłaszcza, że należą do nich gniazda PCIe czy most PCH, a pośrednio (przez zworki) także kontroler SuperI/O. Ogarnij sobie (zbuduj, pożycz, kup itd.) jakikolwiek zasilacz regulowany do 5-10A. Najprostszy zasilacz możesz zbudować z transformatora oświetleniowego 12V/100W (toroidalny) i garści popularnych, tanich elementów.
