PSU cables - same manufacturer, different lines

[chrisr34000]

Hello,

I have two Seasonic PSU's. One is a Seasonic Prime TX 650W (SSR-650TD) and the other one is a Seasonic Prime Titanium 650W (SSR-650TR). Are the cables of these two PSU interchangeable? Or do I need to be very careful not to mix them up?

Thank you for your help.

I would keep them separate - at least until verified they are interchangeable. You might contact Seasonic and ask. Or, if you have a decent multimeter, you could check all the pins.

Note the component end of each cable will be standard as they must comply with the ATX Form Factor standard. It is the PSU end where there could be some differences. I suspect you are fine, but, again, I would verify first.

i have used different wattage cables, within the same manufacturer.

i swapped a Seasonic Focus+Gold 750W , for a Seasonic Focus+ Gold 1000W

they have different PCIe cables (the 1000 w has full flat PCIe cables, but the 750W has capacitor tipped PCIe cables), but the others looked the same. so i swapped the PCIe cables, with the correct ones, & used all the others, & it works fine.

im just sharing my experience. it would be foolish to Advocate cable swapping, but i have done what i posted above, & my system has been fine for a long time.

The manual for each PSU should have a pin-out description for the PSU side. Open each manual to the corresponding pages and look at them side-by-side to see if they are different.

Different manufacturers might be different, sometimes the same brands using different manufacturers are different too, but that is less often.

This is true and what I find most frustrating. I wish the ATX Form Factor standard would develop and adapt a standard for modular cables. But I doubt it will ever happen. Proprietary means bigger profits for the makers - at the consumer's expense.

my brother was putting together a pc about a year ago. could not find the cables for his 850w evga psu and grabbed some from another evga psu that was 750w. little while later he pressed the power button and the gpu went up in flames.

point is, evga, seasonic, corsair just slap their logo on the product. someone else manufactures the unit. there are different manufacturers for the different wattage and tier units within a brand. cables are different between manufactures.

a short while back i bought a pre-build pc.. it came with a decent modular gigabyte power supply but no spare cables.. i couldn't find another suitable gpu cable which i now need and have ended up buying another complete 850 watt supply just because the pre-build came with no spare psu cables..

Unless you can check for sure that the pinouts are the same don't do it.

Ok, thank you for your advice.

That is really sad. I would have contacted the computer builder and demanded the unused cables. I can only hope the unused cables were omitted by mistake and not on purpose.

We always provide the client with any left over cables in a labeled bag inside the motherboard box, with instructions to keep them safe, and separate from other supply's cables.

i did contact them a couple of weeks back.. they said i should have had them and they would try and find me some.. i dont have much faith in ever getting them so just bought another supply.. in todays ever increasing prices the price i paid was a good one and buying another psu solved all and future cable problems i might have..

Well, IMO, it is always nice to have a spare PSU on hand anyway.

I would call them again and remind them. If nothing after that, it is probably a write off.

It's not just nice. I say it's a necessity if you build or tinker at all with computers.

Indeed, my CX 650 has been demoted to backup PSU, Prime PX-750 is the new king of my case.

I agree. This is especially true too, if you are the de facto family/neighborhood computer guru.

part of my thinking when i just thought f-ck and bought another psu because of the missing cables..

....point is, evga, seasonic, corsair just slap their logo on the product someone else manufactand....cables are different between manufactures.

This is absolutely correct. The major Chinese PSU manufacturers (OEM's) and especially from the cradle of the worlds largest PSU production area around Shenzhen, sell directly to anyone with a minimum quantity order. The usual drill: Then the placement into a "Outer Case" and packaging designed by a western based marketing company. It's common to find identical models marketed under many different names and labels and with just restyled exteriors.

Most brand name distributers are without their own production and it is frequently that a manufacturer (OEM) change is made based on better pricing and production costs to simply further increase profits. There have been cases whereby early PSU review samples were manufactured by one company and the following mass production by another. The mark-up or resell value by the branding companies is also extraordinarily high as unlike many other hardware components PSU performance cannot easily be measured by the regular consumer. That's another reason why so many brand distributers featuring the sale or availability of so-called specialty engineered PSU's. So as to all PSU purchases it should come down to the branding suppliers known free back shipping RMA processes, available 24-hour customer services reponse and the warranty length offered.

For a minute I thought I just had a cable mixing problem, but we all know that the real problems are in just simply selecting the right PSU in the forest of Chinese OEM's.

Seasonic is actual manufacturer making their own PSUs.
(except for outsourced lowered quality than predecessor S12III, which just should be dropped from line up)
IIRC they unified their modular cabling between PSUs something like half dozen years ago and before that original Prime serie.

Anyway pretty certain their support would fast confirm in what PSUs series cables are compatible when asked.

I agree. This is especially true too, if you are the de facto family/neighborhood computer guru.

Why not add workplace into pile?
That's where my previous spare/test PSU ended up for regular job:
HP etc market PC in foreman's office had that "want to keep sleeping at morning" booting problem in last autumn and it was starting to take many minutes to get POST started.
So I told him of PSU being the first suspect and that it would be easy to test. (assuming standard PSU&connectors)
Few days later I did half hour overtime after work swapping my test PSU into it and next morning PC had booted up at first press of power button.

The mark-up or resell value by the branding companies is also extraordinarily high as unlike many other hardware components PSU performance cannot easily be measured by the regular consumer.

Doubt mark-up in branded PSUs is anywhere near gaming stuff like those headsets costing more than headphones from actual audio makers...

Because PaulieG already said "if you build or tinker at all with computers". I was adding on to that.
