Yeah, as it turns out, different manufacturers follow their own
standard for modular cables, meaning if you have a thermaltake power supply that shits the bed, and you buy seasonic, none of the cables from thermaltake will work. This is the fucked up part, you'll notice how the cables that plug into the power supply are keyed specifically to only plug into particular spots, well the pci power cables are specially keyed so that you cannot physically plug in a cable from a different brand than seasonic, pretty much idiot-proofing you from killing your graphics card. However
, the 24-pin motherboard cable is not specially keyed, and as I found out my computer just wouldn't power on at all with the old cable, and it gets worse, the power cable for plugging into hard drives either via 4-pin molex or sata power have a 6 pin connector that plugs into the power supply, THIS IS NOT KEYED DIFFERENTLY BETWEEN BRANDS
, so the cable perfectly plugs into the power supply between thermaltake and seasonic, the problem?
THEY MOVED THE GROUND WIRE TO A DIFFERENT PIN
You literally would not know the difference unless you compared the occupied pins of the connectors, and god help you if you fucking mix them up because it's not like the cables SAY "seasonic" or "thermaltake" on them.
So yes, if you buy a different power supply you ABSOLUTELY have to use ALL the cables that were supplied with it.
Now you might be asking yourself, "surely they included some kind of warning for something that could permanently damage your hardware!"
Oh yeah, sure they did, in the user guide which despite being fairly thick, only has 4 pages in english, just inside the cover is the table of contents, the next page has an index and in bold font just slightly larger
than the other headers, it reads "WARNING! IMPORTANT SAFETY INFORMATION"
with some bullet points of some very obvious stuff like
>never open power supply, high voltage shocky heart stoppy
>do not jam dick into fan grill
>do not block ventilation
and NOW the really important warning
>USE ONLY Seasonic modular cables provided with power supply unit.
These bullet points all being the same font face as everything else in the index, not bold, not highlighted, no underline.
Apparently that is their idea of sufficient warning.
My graphics card literally came with a postcard with a bolder warning that there's no software cd included, a big square of paper with huge red bold font saying
