== Step 3: Powering on the card == Assuming you have no shorts anywhere you can go ahead and plug the card into the motherboard and start testing (Alternatively, you can use a Lab Bench Power Supply and a riser to test the card with. Safer for the motherboard and gives you more freedom to move the card around and you get to know the current draw of the card if there is a short). Switch your multimeter to DC Voltage mode and start by measuring the base rails first, if they are present continue to the minor rails. Minor rails turn on in series, if one doesn't start, the next ones in series will not turn on. === Power sequence === The order in which they turn on in most pascal GPUs is as follows: '''5V→ 1.8V→ VCore→ VMem/PEX.''' For example, if 5v does not turn on, everything else in the chain won't turn on either. Hence no fan spin if you have a problem with 5V or 1.8V. If you're missing one of them, check their respective page: * [[5V Rail on Pascal GPUs.]] * [[1.8V Rail on Pascal GPUs.]] * [[Vcore Rail on Pascal GPUs.]] * [[Vmem Rail on Pascal GPUs.]] * [[PEX Rail on Pascal GPUs.]]
