Is it secure to purchase any type of PSU cable extension?
Power supply cable extensions are completely safe when purchased from trustworthy companies. I wouldn't choose random brands on Amazon; you need to ensure they're of good quality since a lot of current will flow through them. CableMod and BitFeenix are both great options.
Hey there,
Ideally you should stick to the cables that come with your PSU. Otherwise there might be problems. Most makers make this clear in the manual.
Do people still use them? Yes. Are they safe? I wouldn't risk it.
While I don't agree with what was said, if you have something like a Corsair RMX850w and can find a compatible cable from Corsair, then it could work.
Sorry, but it isn't always completely safe.
Especially without understanding why the question is being asked.
There are numerous ways to make mistakes, which could lead to unintended consequences.
I need to accept our differences on this.
As noted before, it’s obvious in most manuals that today’s PSU’s are included. They don’t promise your PSU will perform as intended, or they might fail if you use unsuitable cables.
If you take this approach, your warranty is compromised.
I understand your perspective. I don't personally rely on cable extensions since I see them as an unnecessary risk, yet I've noticed many people using them without issues. Take care, my friend.
You're likely to receive varied responses to that question. There are suggestions about modifying the wire color or extending a cable that isn't long enough. I use them, it's your decision, but opt for quality over the cheapest options and keep it short.
My initial cable mod had a loose pin. It was straightforward to find its correct position and reinsert it into the socket, then test with a multimeter. Even premium items can contain production flaws. Ultimately, these devices are mostly assembled by hand in certain factories in China for both OEMs and aftermarket cables.
I remember an instance where we struggled to access the BIOS—it would simply restart. It turned out the brand new power supply had a faulty SATA/Molex cable connection; removing it resolved the issue.
I recommend buying extensions only from trusted suppliers that offer fully modular power supplies, replacing the original cables. A superior choice is to get a power supply with standard cabling that fits your ergonomic needs. Extending cables and adding connectors creates more failure points and increases power loss. It's best to steer clear of this approach, especially with high-performance devices where appearance matters most.
I agreed with everyone that if it can be helped: buy proper modular cable and modular cable kit that has a longer cable if need be. But if this is going to be a cosmetic addition for a non modular PSU to a mostly stock power build, it would be fine as long as you buy from reputable brands or reputable local cable builder. I personally went with the latter.
