Is it safe to cut off the daisy chain part of the GPU cable?

[Mahbub]

Is it safe if I cut off the piggy tail part of the GPU cable and tape it? is there any risk? This looks very odd so i want to do it. I can't afford a sleeved set now and I have an NR200P cabinet which is small so I do not want to increase clutter by using an extension. Help. Thanks.

Why do you want to do that? Cut it and GPU doesn't work!

You could just use 1 cable, and plug both 8 pins in.

Nope .its a 3070ti not safe to use single piggy tail cable.

Why wouldn't it be safe?

[Dukesilver27-]

It'll be fine, why would it be unsafe? Pretty much every manufacturer have those 2x8pins cable, if they're unsafe, why would they produce it?

they produce the piggy tails for lower tier cards.. 3070ti draws 290w max. and a single PSU PCIE cable delivers around 260w or something. so 3070ti are one of those you need 2 cables to run.  

 

yeah it's safe to cut it off.. i used a side cutter and got them as close you get to the 8 pin bracket. if you want you use some silicon paint on the ends, but ... that was me so it was still black.. and non conductive.

I've seen a lot of people run 3080s with single 2x8pins, if this is unsafe, companies wouldn't produce these cables, as it is a potential lawsuit for them. Some manuals does not even tell about how many cable is needed for a 300W GPU or 200W CPU.

 

According to the standards from PCI SIG, 1x8pin supplies 150W at max, 75W from the PCIE interface, but this does not translate to the cable. The cables itself could far exceed this standard, hence the 2x8pin cables. 3x8 pins could be supplied by 1x8 pin and 2x8pin cables, it's been used by a lot of people.

 

Miners have been using 2x8pin cables for GPU mining for years, if it is unsafe, we would have seen the news everywhere.

it is not unsafe.. it's just that max draw at the GPU end is 150w pr 8 pin plug, 6 pin is what.. 75w.. that's perfect for one cables. but some cards that draw ca 250w .. will need more than 1 8 and 1 6 pin connector.  

but if your cards draws above 200-250w .. one cable will never manage and you need 2 cables for 2 8 pin to get 300w..

may i see a  picture

[Stahlmann]

If it would be unsafe, why would PSU makes take the risk and include them anyway?

 

I've been using a single cable with the pig tail for my 2x8 pin 3080 since i got it in 2019 and it's been working fine pulling 320-350W under load.

don't have one here, with a needle you should be able to disassemble the first plugg as they are hooked in to the plastic, you can remove it where it's crimped to the plug, and replug it. 

my PSU came with extra without piggy tails.. but have done it for customers that didn't want it there.

i don't know if should go through the lengthy process of plugging out and replugging to just cut the extra wire with a scissor and tape the end

yeah, side cutter as far down into the plug is faster

 

search for liquid electrical tape on your local part store to isolate it.

okk.. btw will it void warranty

for that cable probably.. if it's modular. if it's nonmodular for the entire unit.

I made a post earlier in the PSU forum, and the replies were basically that I'm an idiot and it's my fault for not checking before purchase. In my case it's about not having an included single 8-PIN cable in the set.

Those who have supercharged high-end cards would appreciate a 2x8-PIN, no doubt about it. But thats only one segment of the market. Right now, at this moment, my local retailer sells EIGHT releases (four Radeon and four GeForce). Within that, there's multiple variants by all the brands.. MSI, Gigabyte, Asus, Sapphire, PNY etc.. I'm not going to count them all but it may be up to 50 different products that DONT need split cables

It's quite bloody clear that its a HUGE trend these days for DIY builders wanting to show off their rigs. Just look at the massive range of current cases that have tempered-glass panels.

And the whole point of a fully modular PSU is to minimize cable clutter. Having ONLY daisy-chained (or piggy-tailed lol) cables is entirely at odds with modularity.

I've been speaking to my PSU manufacturer, and theyre going to send me a single cable. I've implored them to consider this as a regular inclusion for all of their products in the future, not just a one-off to me. I was planning to buy another one at the end of the year, so we'll see whats in the box... in all fairness though, I wouldnt expect a company to roll out a revised accessory kit in such a short timeframe, but I'll keep an eye on them over the next year.

those deep into modding get the pin out on each contact map, or just measure it and build their own cables without the piggytail. 

or you get some from cable mod or similar companies, or more common cable extenders, those are all without piggytail. 

 

since cables without pigtails is it's own market.. i don't think they will ever change accessory kit..

LOL don't start on me with that ! I seriously considered making my own cables recently (I was into electronics a loooooooong time ago) until I woke up to myself and realized how catastrophic one mis-wired lead in the ATX cable madness would be. As recently as four days ago it got into my head again and I spend ages looking for a local paracord supplier. Fortunatly, I didnt find one. I really should stay away from grand plans (and the internet) when I've had a few wines.

I think I won't cut off lol. I am ok  with the wire looking a bit ugly in order to have mental peace

get cable extenders..

except that my case is NR 200p.. very small.. getting extensions will create more chaos inside the case

if you need cables that are for an exact lenght.. order from cable mod or similar companies. these swap out the entire modular cable. you can even get contacts that are angled 90 degrees.. pointing up or down.. your choise.
