Title: Modular PCIe connector to PSU is a little loose Post by: adaseb on June 09, 2016, 01:25:16 PM I am talking about the blue end pictured below. If you wiggle it a little it moves, is there anyway to make the connection more solid to the PSU?
I noticed that one of the modular cables was at a slight angle and the cable was a little hotter than the other one. http://www.corsair.com/Media/catalog/product/h/x/hx-txm_cable_pci-e_k_1.png Title: Re: Modular PCIe connector to PSU is a little loose Post by: philipma1957 on June 09, 2016, 03:55:55 PM I am talking about the blue end pictured below.

I will try to photo what I mean. check for melting no melting in this psu https://i.imgur.com/4OgG9MS.jpg no melting in this cable https://i.imgur.com/sUWfcTY.jpg here is the hard part copper wire this one is 24awg and it is too fat but it was handy for demo https://i.imgur.com/fNSigaU.jpg one wire in one socket now the row of four are all the same so do the row of four sockets and the row of 3 are all the same do the row of 3 sockets when you do this no loose wire from row of 3 can touch row of 4 or short same as no wire from row of 4 can not touch row of 3. this is why this fix is not code but it works if done correctly. https://i.imgur.com/75epDsQ.jpg Title: Re: Modular PCIe connector to PSU is a little loose Post by: Unacceptable on June 09, 2016, 09:34:23 PM So the wire strand acts as a shim between the plastic "housing" & the inner connector ???

Title: Re: Modular PCIe connector to PSU is a little loose Post by: adaseb on June 10, 2016, 04:33:31 PM I think the only solution here is maybe to stick some small pieces of paper on both ends to the blue connector doesn't sit at an angle.

I noticed that one of the modular cables was at a slight angle and the cable was a little hotter than the other one. http://www.corsair.com/Media/catalog/product/h/x/hx-txm_cable_pci-e_k_1.png Gently and very gently bend the pins in the back of the PSU off centre by a very small amount. Use a small jewellers screw driver. Plug will then push in and make a better contact. If you are feeling brave, use a molex extractor and drop the female terminal from the receptacle on the free lead. Inspection under a magnifying glass will show the seam where the pins are folded. A gentle squeeze with some plyers and some practice will close the terminal back up and improve the connection. All crimps of this type wear over time. The industry could not have picked a worse type of power connector to use for mining machines. When they come loose they get hot then burn out. They are changeable but I find it best to use a rework station on the of PCB end and use the hot air to replace the sockets in one go. Good luck!

Replacement of them is best but many people do not have the gear. Or like me some have older eyes that do not see close well. He could buy a cable from the psu company. Some companies do sell replacement cables Title: Re: Modular PCIe connector to PSU is a little loose Post by: adaseb on June 11, 2016, 06:10:35 PM I am talking about the blue end pictured below.

Some companies do sell replacement cables I don't think its the cable because I tried different cables from different PSUs, it seems this issue is from the male end on the PSU.

Then gently bend the pin in the PSU socket half a mm. It will have an instant effect. My SP20's had the same problem and this cured them all.

Opposite the way its leaning ? yes but depending on how the pin got off set you could snap the pin no melting in this psu see all my pins are lined up are yours all lined up? is the one set of pins in the psu all just off by a little compared to the other sets of pins? or is just one or two pins off on the one psu socket? https://i.imgur.com/4OgG9MS.jpg Title: Re: Modular PCIe connector to PSU is a little loose Post by: adaseb on June 13, 2016, 09:08:53 PM To the naked eye, it looks perfectly straight.
