Dear Community,

My power supply died and I had to replace it with a different one. I noticed that the 6pin pci cable used to power my gpu was different than the one before. The one on my previous power supply had 6 wires connected from the power supply to the 6 pins. This one has 4 cables and a yellow cable that loops 2 pins together (see pictures). What is the difference in these two cables and can I swap one out for the other. or should I buy one such as the previous one I used?

Kind regards,
Shandor

NEVER use PSU cables from another PSU - it can damage your components.
Don't worry about the wiring on the new cable, it's fine. The middle pin on lower row is not connected as per standard, but it usually get's +12 V instead, that's why new cable has it connected with the other +12 V line.

One more question. So I had done as you said and thanks for clearing it up for me. I asked the question because I noticed my gpu crashing way more often than before since the change of psu (the old one was 400W and the new one 600W). Do you know what could be a possible cause for the problem?

I would like to add that for the time being I have my case open since I was worried that the wiring might be incorrect or that the new power supply was creating too much heat for the gpu.

Thanks for your help!

Judging by the pictures you posted alone, the new PSU might be of lower quality then old one, which could be the cause of more crashes. However, if you had GPU crashes with old PSU and still have them with new one, good chance is its the GPU that has problem.

Well the old PSU just died (made the fuses in the house pop and didnt do anything afterwards) when trying to boot last week. It was a crappy one provided by medion (the manufacturer of my pc) since I wasn't into building a pc myself back then. And i replaced it with a corsair PSU, so I would think that the quality must be somewhat better right?

Not all Corsair PSUs are great, some of them are mediocre too. But indeed I would expect any Corsair PSU to be not worse then some prebuilt junk. However all their good units have x50 watts, so if you got 600 W unit it must be one of worse ones. Let me guess, it is CX/CXM with green label?

I might be missing something, but it doesnt seem like it is.
It is this one: http://www.coolermaster.com/service/support/model/RS-600-AMBA-D3/
which is the Silent Pro M600 - 600 Watt 80 PLUS Bronze Certified Active PFC Power Supply.

Ah, but that's Cooler Master, not Corsair.
Well, that model got 9 out of 10 mark on Jonny Guru review, so we can assume it's quite good. So back to the problem with crashes, if your previous PSU abruptly died while working, it could cause your GPU have more trouble then it had before.

Okay finally I am getting somewhere. Thanks for all your help thus far, let me explain the situation as clearly as possible and maybe you can help me find the proper solution. So the computer died when trying to turn it on for the first time that day. It had been off for the last day or 2 since I was busy studying. At that moment when I tried to boot the pc it immediately turned off (never really booted). So I tried plugging it into a different wall socket and thats when the fuse popped and the computer stopped working after that.

I would like to know your thoughts on this and whether overclocking could solve the problem or not? or maybe you have a better idea. Thanks in advance

What kind of crashes exactly you experience now? Is is computer freeze (forcing reboot) or game/program crashes but computer still works afterwards or it just powers down/reboots straight? Was it happening same way with old PSU? Does it happen only when gaming/stressing machine or when idle/just browsing internet too?

With the old PSU it actually never crashed. On very rare occasions a game would stop working, but I could just relaunch the game and continue afterwards. It wasn't at all a problem.
Since the new PSU, crashes only happen when playing games. Other stuff works fine. The following happens: so I am playing the game (might be for a few minutes might be for less) and then the screen turns black. I can hear the windows error sound (same as when a game crashes or something) but the screen remains black (my display mentions that no source could be found). The only way to solve it as far as i have figured out is to reboot the entire computer. After reboot it works fine again until I launch a game. Then it crashes again after a minute or sometimes 10.

You're going to need to list full system specs to get any real help here.

The silent pro is an ok unit, you'd hardly rate it 9/10 nowadays though (that review is circa 2009) & it's really a 500w psu not a 600w one in real terms.

It is however better than anything medion/akoya have ever used in their prebuilds though.

F*ck. The problem is, unfortunately I read online that medion locks their motherboards so you cant switch gpu's and I cant afford a full new pc right now (student problems). Anyways, thanks for all the help! Really appreciate it!

These are the current stats from my pc: https://www.ultraimg.com/image/MsEe
and YES I know this graphics card is outdated, but it worked perfectly for the games I play before the PSU died and I changed it out. And as of why I havent upgraded, I cant (medion doesn't allow it and i cant afford an entire pc upgrade, im saving up though).

Thanks in advance!

Alright, thanks for your advice! I am going to try and borrow someones gpu to test at first and if it works I can buy one. Really gets my hopes up :).
Would the MSI GeForce GTX 1060 Gaming X 6G or the MSI GeForce GTX 1070 Ti Gaming 8G be able to be powered by my cpu? Or perhaps even an MSI Geforce GTX 1080 Gaming 8G?
