Do you have access to extended length modular PSU cables suitable for SFX PSUs?
Do you have access to extended length modular PSU cables suitable for SFX PSUs?
I own a new SFX PSU for my PC. My previous unit wasn’t modular and I never faced length issues, but the new one is modular and the Molex and SATA power leads are both too short—just about 3 inches. I’m considering using SATA power extenders instead, but that would look bad and would eliminate the cable management benefits of a modular PSU.
The SATA power leads don’t have enough space between the plugs to reach from my DVD drive to my hard drives, which is really frustrating. Right now, my DVD drive and hot-swap enclosure aren’t powered, and managing the cables is a real headache because I had to work hard to figure out what to do next.
What I could do is add a lead for Molex and a SATA power lead with about 3 inches more space between them, plus a bit more gap between each connector. Or maybe just two 3-inch extensions, like those Corsair Type-5 models?
Anyone have any idea if this is something that exists or if it can be custom-made?
PSU is Corsair SFX SF-series 750W
Thanks for your help.
ATX 2.4 or ATX 3.1 model?
If it's ATX 2.4, compatible power cables for CableMod C-series Type 4 can be used instead of original ones.

For ATX 3.1 or custom needs, the configurator lets you design your own SATA power cable.

Using the custom tool, you can choose connector positions and details like length steps, color, and paracord wrapping.
Thank you
I'm in the UK but I don't mind importing something if it saves me messing about making up cables myself like I thought I would have to, does anyone know if there is a site in the UK that does this? because I can't seem to find anything
My PSU just says ATX 3.0, not 3.1 or 2.4? here's the photo's of the box:
there isn't an option for SF750 3.0, would I pick 3.1?
Corsair offers longer Type 5 cables. For SATA models refer to the provided link. This specific model measures 30"/75cm. All Type 5 cables can be found on their site.
Thanks a lot for the links. I'm unsure if they're suitable since the Molex and SATA connectors are too close, but it's better than my current setup. I might be able to find them for sale in the UK.
Yes, ATX 3.0 and 3.1 are practically identical. The main change lies in ATX 3.0 supporting 12VHPWR by default, whereas ATX 3.1 uses a 12V-2x6 connector (an evolution of the earlier design).

CableMod also has a European branch, providing shorter and cheaper shipping options. Their EU store includes a custom cable configurator:

Ahhh, OK, so the wires are the same but the sockets have a change, I guess this has something to do with the pictures that came up a lot on reddit a little while ago of melted GPU power plugs? I was interested, thanks for the link
great stuff, thank you for your help
Yes.
Melting 12VHPWR connectors was a HUGE issue, especially for RTX 4090 owners. This issue actually continues on to this day, not as severe, but still.
IMO; it was bad move by Nvidia to try and squeeze 4x 8-pin PCI-E connectors all into one, much smaller 16-pin connector (12-pins to carry power, 4-pins for sense).
As far as i've heard it, idea was to reduce the power connector socket footprint on the GPUs. But given that how beefy modern GPUs are, i don't see much point behind that argument. And on the flip side, AMD Radeon GPUs still use the standard ATX power connectors. Only Nvidia GPUs (namely RTX 40-series) have the new 12VHPWR and 12V-2x6 connectors.
Nvidia has pushed the new power connector for 2 generations now. It started with RTX 30-series, where the connector was essentially same as 12VHPWR is, with same pinout. But with a diff that the RTX 30-series connector didn't have the 4-pins for sense. But did have the 12-pins for power still.
IMO, Nvidia should revert back to standard ATX power connectors. Since those work and well. I don't see why to complicate things and make something worse, which otherwise works fine.
I’m getting the details clearer now. Coming from someone who rarely spends money on new things, I wasn’t sure what those connectors were or what they did. But after researching how the wires work in the PSU I have, I understand better. The 12VHPWR plug is a 3mm pitch Molex micro-fit, and while it claims to handle the same current as regular connections, that’s not accurate. Making things smaller actually increases heat buildup, not just from resistance but because there’s less space for cooling. On modular PSUs, the wires use Molex micro-fit on the back, so I’m curious which side of the cable would be more likely to overheat first. Luckily, my system won’t need much power, so melting wires probably won’t be an issue. Yes, it does seem odd—there’s plenty of room on GPUs, and small plugs make it hard to hide cables inside connectors, which might explain why people still stick with the old style.
True. Usually, it has been the one on the GPU side. And that too due to not 100% perfect plug-in (partial insertion). This is also due to the reason that most GPUs are horizontally in the PC case and to close the side panel afterwards, the power cable has to do solid and severe bend. This, side panel pushing against fat bending power cable can dislodge the power cable from the GPU connector, thus making partial insertion and that has lead to the cable melting in most cases. Things with 12VHPWR cable are so delicate that many (if not all) brands that supply these cables (e.g PSU brands, custom cable brands) have put out in-depth guides on how to properly use the damn thing. E.g here's CableMod's guide: https://cablemod.com/12vhpwr/ GamersNexus covered this melting connector issue in-depth, with several long and in-depth videos. I'm not going to link them all here, you can look up others if you like, but the best one of them would be this one: View: https://www.youtube.com/watch?v=ig2px7ofKhQ In that video Steve managed to get the connector to melt. Proving the issue and it's severity. While most of the world thinks it is user error, by not inserting the cable fully, thus making it melt; the same isn't with the ones who repair electronics on daily basis. Alex, founder and owner of Northridge Fix, who has to replace the burnt connectors on RTX 4090 GPUs on daily basis, can tell from experience that the connector melting isn't user error. One of many Alex'es RTX 4090 repair videos: View: https://www.youtube.com/watch?v=nplGX4SqABw There are more RTX 4090 repair videos if you look it up from his channel. I think the main issue here is Nvidia's pride. They developed a new power connector, didn't test it in-depth, released the "iffy" connector on the market and when it was established that the connector is bad, rather than reverting it and going back to the trusted and known to work 8-pin PCI-E connectors, Nvidia instead released an "updated" version of their connector, now called 12V-2x6. Over the years, there have been other "innovations" with power delivery within PCs. Some more successful than others. To name some of them: Corsair Shift Further reading: https://www.corsair.com/us/en/explo...t-...d-to-know/ Idea with this is, that PSU power connectors, rather than coming out from the opposite side of main power input, are coming out instead from the side of the PSU. Look the Corsair's announcement for images. Corsair claims that it helps to improve cable management. Well, it does, but only in specific use cases. Namely only then, where there's enough room behind MoBo tray, to reroute the power cables. But since most cases have little room behind MoBo tray, there are only select few PC cases, where such PSU can be used. And PSU must be install with fan down. Else-ways, the cables will come out of the other side, where usually transparent side panel is (when PC case has PSU shroud, PSU can't be installed fan up at all). Seasonic Connect Further reading: https://seasonic.com/connect/ Seasonic's way to improve cable management. With Connect, Seasonic actually relocated the production of +5V and +3.3V rails to the Connect unit, making PSU's own footprint much smaller. But as with Corsair Shift, Seasonic Connect also has select few PC cases where it is compatible. Intel ATX12VO (12 volt only) Further reading: Idea with this is, to move the +5V and +3.3V generation from the PSU to MoBo. Whereby PSU only converts AC to +12V DC and feeds it forward to MoBo. MoBo then has to take +12V and make +5V and +3.3V out of it + having power connectors on it to send it along (e.g SATA and MOLEX). On one aspect, this makes the life for PSU manufacturers much easier, since all they need to do, is converting AC to +12V DC. But on the flip side and where i think it is a bad move, MoBo manufactures now have to implement the circuit to transform +12V into +5V and +3.3V. I don't have much faith in that, namely due to the lack of experience of MoBo manufacturers taking this over. I'd rather let the power delivery to be made by PSU (since PSU manufacturers have decades of experience) and MoBo be as it is now. On top of that, Intel ATX12VO would make MoBos to cost far more and with latest MoBos, the real estate on MoBo PCB is premium. There's more space on ATX MoBos but micro-ATX and mini-ITX MoBos would struggle a lot with this. E.g here's one such ATX12VO MoBos: https://www.msi.com/Motherboard/PRO-H610M-12VO H610 chipset, so barebones as it gets. Power connectors wise: no 24-pin ATX anymore. Instead 10-pin ATX + 6-pin PCI-E is in place of it. Also has 8-pin 12VEPS for CPU and only TWO 4-pin molex for SATA. Two connectors for SATA power are way too little. Even my PSU has six power connectors for molex/SATA and my PSU isn't that high wattage either, only 650W unit. So, i don't think the Intel ATX12VO would gain any ground in enthusiast PC building. Maybe in OEM/prebuilts (e.g Dell).
