Contiusa Posted April 16, 2019 Share Posted April 16, 2019 Hi guys, my motherboard has a 12 pin CPU power connector (Z390 UD). I will overclock my i5-9600K to near 5Ghz (custom loop). But my PSU (RM750) has only an 8 pin connector. Does Corsair offer any kind of extension (I saw some individual connectors for sale) or do I need a new PSU? From what I saw, Corsair does not have any 650/750W PSU with 12 pin CPU connectors (which is strange, since nowadays 750W is almost overkill for a regular gaming rig). I won’t buy a 850W plus PSU because my consumption will never reach the point to spin the fan and the PSU heats up my case, as it does now with the RM750, that won’t get to the point of spinning the fan but gets fairly hot inside the case - never really understood the quiet fan feature if it means heat up the case. So I rather be with a 750W PSU (I just have one GPU and it is unlikely for me to have a Titan or any sort of similar card). I've seen posts about the EVGA units, but I rather stick with Corsair or Seasonic (I know that Corsair has several Seasonic units as OEM). I appreciate any feedback.

DevBiker Posted April 16, 2019 Share Posted April 16, 2019 That PSU has 3 connections for PCIe -or- CPU. Depending on the power needs of your GPU, you can get just one more CPU power cable and use that. Link to comment Share on other sites More sharing options...
Contiusa Posted April 17, 2019 Author Share Posted April 17, 2019 Cool, thanks, I found the cable at Aliexpress (for the RM series) and ordered it. I still have one PCIe / CPU connection left to use. Regards, Link to comment Share on other sites More sharing options...

I still have one PCIe / CPU connection left to use. Regards, I highly recommend against using any PSU cable purchased from Aliexpress in any PSU. You cannot guarantee that the cable is actually meant for the PSU in question and in doing so risk damaging the component you plug it into and even your whole computer. This would also void any warranty and therefore you would not be covered if you did indeed damage anything in your computer including the PSU.

Contiusa Posted April 20, 2019 Author Share Posted April 20, 2019 (edited) I highly recommend against using any PSU cable purchased from Aliexpress in any PSU.

This would also void any warranty and therefore you would not be covered if you did indeed damage anything in your computer including the PSU. The problem is, I only found the cable in local US stores. Not even on Amazon. The cable that I bought was also available on e-Bay. The same vendor has cables for the RMX series (or some other model). Do you know any vendor who ships it to Brazil? Corsair's site was asking me an US and Canada address only IIRC. I incur in the risk, but after buying products from Aliexpress for years, what I see is that many of them are just OEMs from known brands (nowadays almost everything comes from China, Taiwan and such). I just bought a rad that seems to be the OEM of EK (double fins, which is not common). In fact I like Aliexpress more than e-Bay - way better tracking system / paying system. I could try and contact Corsair Brazil, but I have a sense they won't order the cable and sell it to me. Am I right? Or it is common for local Corsair support to order and sell these things?

At the very least I would recommend you reach out to the Brazil Support team and see what they can do to help you. suportecorsair.com Link to comment Share on other sites More sharing options...
Contiusa Posted April 24, 2019 Author Share Posted April 24, 2019 I'll try to open a ticket just as a curiosity, but the cable I ordered is exactly the same as the original (same flat black cable, same connectors). It is not a custom / braided cable, so I tend to think it is the same OEM that Corsair and other brands uses. Of course I’ll compare both cables when it arrives. Let’s see.

gato011 Posted May 15, 2019 Share Posted May 15, 2019 I have the same problem, which cable did you buy? Link to comment Share on other sites More sharing options...
Corsair Employee Corsair Notepad Posted May 15, 2019 Corsair Employee Share Posted May 15, 2019 If you guys purchase cables from a third party such as AliExpress you cannot be guaranteed to be getting a cable that is compatible with your power supply. Even if they look the same the cable could be a completely different pinout or using the wrong type of wiring which WILL damage your components. If this happens you are not covered by any warranty and will be out the cost of replacing your damaged parts. Link to comment Share on other sites More sharing options...
gato011 Posted May 15, 2019 Share Posted May 15, 2019 There is a cable of corsair for this problem? Link to comment Share on other sites More sharing options...
DevBiker Posted May 15, 2019 Share Posted May 15, 2019 Look on Corsair.com. They have all of the cables available in packs or individually. Link to comment Share on other sites More sharing options...
