Dell Optiplex Won T Power On. - Dell OptiPlex 755. The current Optiplexs may be hardly upgradable but can still take a GT 1030 and may be a few others.

It does depend however if you have an Energy Star 40. The LED indicator on the PSU helps identify if the power issue is caused by the power supply unit. Dell Inspiron XPS OptiPlex Precision and Vostro desktop computers include a power supply with a integrated self-test BIST feature that helps diagnose the health of the power supply unit.
Not so in this case.
The Optiplex model is for business use not suitable for gaming or upgrading Mary G also said in a post no video Not true. Video can still be played on them. Dell Inspiron XPS OptiPlex Precision and Vostro desktop computers include a power supply with a integrated self-test BIST feature that helps diagnose the health of the power supply unit. So just about 90ish of the time when a desktop wont power on a new power supply is the fix right.
