PSU cable extensions

Hi,

I have a Seasonic prime gold 850w, which has 750mm PCI-E 18AWG cables, and 610mm 18AWG 24 pin cable.

I ordered Phanteks extension bundle which are 500mm 18AWG cable.

So in total that is 1250mm for PCI-E cables and 1100mm for 24 pin cable.

Is this cable length ok with the extensions? It is quite long in total.

Thanks

It is fine. I have used cale extensions for years with no problems. I even made my own molex extensions that are just over 2m long and they work fine as well.

Thanks for reply, hm I read some bad reviews of the phanteks ones on another website, I think I will go with the cablemods instead.

Mine are Phanteks and the quality is excellent. The kits even come with cablecombs.

Mm not sure why on another retailers website, there are about 5 reviews saying that the cables damaged their system, or crashed system then they removed the extension cables and their PC was ok. After reading that it has now made me worried about them + they are too long, so I ordered some other ones, maybe those problems are rare I don't know, but still bit worrying, I think it could be because they are too long and causing voltage drops or something I don't know. Maybe a bad batch as the negative reviews are all around the same time which was december.

All I know is that I have this kit and have had zero problems with it.

The 24 pin cable is 500mm plus my psu's 24 pin cable at 540mm = 1040mm.
The 8 pin cable is 500mm plus my psu's 8 pin cable at 540mm = 1040mm.
The pci-e cable is 500mm plus my psu's pci-e cable at 580mm = 1080mm.

Then there are my beastly 4 pin molex connections that are 2100mm long each that are plugged into my psu's 515mm molex lead giving a total of 2615mm. These are powering my water pump, fan controller from which there are a further six 2m 3 pin fan cable extensions to my radiator fans. I even had six 2 way splitters on the end of these so I could run push/pull on both rads at one point. All of these have given me no problems.

All I can think of is that there was a faulty batch as you assume, they were using poor quality psu's or user error. For all we know they may have plugged them directly into the psu's modular cable ports in which case they were lucky they didn't blow up their psu's and other components.
