![]() You try to avoid theoretical maximums for production. Typically, power supplies supplied half that for peripherals (5A for both comes to mind). Molex, LLC and TE Connectivity (TE) will collaborate on the launch and promotion of select new connector and cable assembly products that enable the growing number of high-speed applications required as data centers evolve with hyperscale models and increased virtualization. With the 14 AWG cable, you could get 11A on 12V circuit (Pins 1 and 2), 132W, and 11A on 5V circuit (Pins 3 and 4), 55W. And OP 44A/connector.įrom SuperUser (but no reference to external source) Is this a floppy disk connector to the power supply?: Increase wire size to 14 AWG and you do get 11A/pin. The most popular connectors from JST, Molex & Hirose are also possible for connecting the 18650 battery to your applications with ease. Odds are that no actual circuit will have 18A sourced due to other factors. ![]() There are other factors: Ambient Temperature. All applications should be tested by the end user.Īs in designer is responsibe. are intended to be a guide in the selection of a connector family. That is 18A supplied and 18A sunk (Ground). 36A per connector theoretical maximum, if 105☌ and 30☌ are maintained. With every circuit energized, for a 4 in-line connector, with 18 AWG wire is 9A/pin. Derating connector due to adjacent conductors. The female connector is usually found on the end of a cable, and it slips inside of a. Table shows number of circuits vs size of wire. The Molex connector is one where the male/female terminology is a bit odd. The maximum current that can be carried is a function of the maximum temperature of the housing (105☌) and the maximum temperature of individual connection (30☌) (and maximum temperature of wire insulation) (and length of wire) (and ambient temperature). Through a collaborative process, Molex can help users develop a complete solution for board-to-board and blind-mate applications using the best combination of PCB-mount, cable-mount, and in-series adapters. The problem is a little bit more complicated than that. Molex's SMP subminiature connectors offer excellent performance from DC to 40 GHz. So 4 pins at 11A/pin leads to the 44A of OP. However, it appears that the power specifications still only allow for 75 watts from the socket and most devices obey this constraint.Max. However, my understanding is that PCIe 2.x+ requires that the slot be capable of delivering 150 watts of sustained power. I can't seem to find a hard source and since I'm not a PCI-SIG member I can't check it against the data sheet. PCIe 2.1 and 3.0 can deliver 150 watts when using a 16x slot.Ĭan you please post source of "PCIe 2.1 and 3.0 can deliver 150 watts when using a 16x slot."? PCIe 1.x and 2.0 allow for 75 watts of power to be drawn from the motherboard itself when using a 16x slot. Higher power cards should always use dedicated PCIe connectors. However, this is safe for low power cards only. Since your 7770 will only draw a few watts from the auxiliary power connector, it is safe to couple it to a 40 watt Molex connector if you so desire. ![]() Since the 7770 is rated at 80 watts, it needs a power connector to make up for the 5 watt shortfall. The AMP Netconnect from Tyco Electronics topped the honors list registering. PCIe 2.1 and 3.0 can deliver 150 watts when using a 16x slot.įor compatibility reasons, many GPU manufacturers will only ever draw 75 watts from the socket itself, drawing the rest from the dedicated PCIe power connectors. ![]() 6 pin PCIe connectors are rated to deliver 75 watts each. Molex connectors are rated to deliver 40 watts. The pc seems a bit louder when using the pci-e from the psu rather than the moleex, but maybe its just using the right amount of power now? I don't know But should I use this connector, or the 6pin that comes with the power supply? The molex helps me save room in the case but i don't know if using molex is safe. I have this psu - My question is just that I bought the Sapphire Radeon 7770 and it came with a 4 pin molex-6 pin cable.
