![]() I have not seen anything about the molex connector being unable to withstand a 75w pull, but I need to make sure. More importantly, a SATA cable with molex header should be fine, right? It goes directly from the PSU using the SATA/PERIPHERAL port to the connector on the card. Is that not right? If it is the connector, then theoretically, could I not have a 6-pin cable coming from the SATA/PERIPHERAL port on the PSU directly to the 6-pin on the risers? I would likely need a cable like that made at somewhere like CableMod though. I thought that with SATA, the problem is with the SATA 15-pin connector, not the whole cable itself. You can check them out for yourself below (I believe you can see them without having an Amazon Japan account): Unfortunately, the risers did not come with any manual. Any and all help will be most appreciated! Sorry for the long read but I have been going in circles for three days all over Reddit, Tom's Hardware, and the Internet. I have seen confusing info about the 6-pin port being better than molex, but I think that may have been because some adapter with molex was involved, so I need a straight answer about how to directly connect these risers to my PSU and whether my powering method for the 3070's is also safe. I have only read SATA is bad to power risers with without getting a fully clear answer on whether my cards are powered properly on one VGA cable to dual 6+2 and whether the 4-pin molex port on my risers is the way to go for powering them, completely ignoring the 6-pin port on the riser card All I need is peace of mind that I don't have a fire hazard in my guest bedroom. If someone knowledgable confirms that what I did with the dual molex cable works, I was going to just have CableMod make two molex cables with the dual connectors for my PSU (their Japanese store makes custom cables for the SuperFlower PSU) and be done with it. Regardless, that still leaves two cards to power risers for. I have a third riser card connected to the molex connector, but I am worried the cable may not be rated high enough for the wattage if it has SATA connectors on it (or is it only the SATA connector itself that is the problem?). The only other cable the PSU came with is a peripheral cable that has one molex connector and two SATA connectors. Since I heard two risers can safely be powered by one cable, I have two of the three molex connectors connected to two riser cards. I currently have one cable that splits into 3 male molex headers. That being said, which is the correct option? There are no cables that go from the 6-pin port on the riser to my PSU's SATA/Peripheral port, right? So far, it seems the answer is the 4-pin molex on the riser. The risers came with the usual 6-pin to SATA adapter cable, but we all know SATA is a fire hazard waiting to happen, as I have seen the Reddit bot remind people in every thread I have read, and have also seen countless warnings here on the Tom's Hardware forums. I have the usual risers with two 6-pin ports, as well as a molex connector. Now, assuming that part is not a safety hazard, I really need an answer about the riser cards. Otherwise, having only 9 VGA slots on the PSU, I could never power 5 or 6 cards. ![]() As far as I have seen (though want clarification), it is safe to have both of the GPUs 6+2 ports connected to the PSU's VGA PCIe port through one cable (VGA PCIe to dual 6+2 pin headers). ![]() My cards are all connected to the PSU via a splitter cable that came with the PSU that has two 6+2 pin headers. My PSU is a Super-Flower Leadex 1600 Platinum. ![]() I am set up with an ASUS Prime Z390-P motherboard running GPUs. After searching about 60 threads from the past two years, and not finding a straight answer anywhere, I thought it was enough due diligence to warrant registering and making my own post with my setup and seeing if I can get a clear answer to avoid a future house fire with my rig.įirst, the part I am mostly sure is okay but want to check before I get to the part where I can't find any clear answer.
