![]() And good 3mm nylon support filament may help prevent future repeats.Īlso replacing the stiff Prusa power wires. Switching to the most recent Rambo/Einsy box. The reason for failure may be down to strain on the wiring. Molex connectors can work for a long time. Hi, all.Its probably a silly question, but I buy a lot of hard drives with SATA and molex power connectors and I was just wondering if there was any. And caused my power wires to break prematurely. Following my experience with the MK1 prusa, which used ABS filament for cable bundle support. ![]() 16 AWG requires a different crimp tool however the tool being reviewed only supports 18-24 AWG. The supported wire range is from 16 AWG thick down to 24 AWG, which is a good span. Molex connectors are just a shitty design. Two molex > one 6 pin is better, but still bad really. Why designers felt it was better is beyond me. Single molex > 6 pin is very bad, it's asking the molex to draw well above its rated current. ![]() I was very careful to make sure the cable strain relief fittings were tight. The Mini-Fit Jr connectors have 4.2mm (0.165') pitch, with a latch (this is known as positive locking, meaning it cannot work itself loose). Honestly, the SATA power connector is still a terrible connector from a usability standpoint. Rambo mini.output to drive a MOSFET switch which removes the high current switching off the mini Rambo. Some people fit xt60 connectors to replace the molex connectors. Some people bypass the connector and solder the wires directly to pads on the board. Some people replace both sides of the connector. Unfortunately overheating one part can overheat the other and make it less satisfactory and more likely to fail again. Often people replace one side of the connector and not the other. The wire bundles tended to work their way out of the case and put strain on the connectors. Which had cable ties instead of screwed clamps. This can be exacerbated by the spiral wrap insulation used on the first MK2 printers. Problems seem to occur due to poor insertion in the first place. Generally the genuine Molex versions are good. It is almost impossible to estimate what your problem is without knowing something about it.The molex connectors come in various qualities. When submitting a problem, include a complete list of your system components include part numbers, all Power Supply Voltages, and their output ratings. For ATX 12V power connection, it should be greater than 18A. Power supply of 450 watts (and above) is highly recommended for system stability.ģ. ![]() These three connectors connect to the ATX power supply and have to work together to ensure stable operation of the main board.Ģ. Even though the power supply delivers 60A of 12V total power it does not deliver over 15A to any one connector.ġ. There for if all the rails in the power supply are rated at 15A then there is no way for that power supply can supply a recommend 12V rated at greater than 18A to the ATX 12V connector on the motherboard. Yes, I read the specs for the supply that is how I know it does not meet MSI?s recommendations for the ATA 12V connector.ĭid you read all of the industry specifications that manufacture say that the power supply meets? If you read those specifications you find that each of the +12V rail have to be independent of each other and the +12V supplied to the ATA 12V connector must be independent.
