Situation: I have an i7 2600k oced just on 4.1ghz with 1.175v only, 240 GB 840 samsung SSD, HD westerdigital 64 Mb buffer 1 TB, 16 gb of ram, 580 GTX , 700 W true power sirtec PSU. MSi-P67A-c45 mainboard . Asus Xonar STX
Yesterday, i restarted this system and for some reason it wouldn`t get to load windows or wouldnt show up my Starup Logo from MSI . It just wouldnt do anything. I started to remove piece by piece from my computer, until i reached the HDD ! . WHen it was the HDD to be removed and checking to see if he was the problem, the system started to boot up , and even Load windows on the SSD . I thought it was a cable problem, so i took the cable from another PSU that i have in another computer @ home, a sata cable from that i3 system which had a 500W Antec neopower, and a power cable that came str8 from that antec psu to power the HDD. It woulnd boot with those new cables ALSO ! i mean the ones from the 500 Antec Neopower. So i took the HDD and put it in the i3 system, with teh 500W neopower antec psu. THE I3 SYSTEM WITH 500W newpower booted with the HDD that caused me problems on the I7 system. Ok so i was wondering whats wrong ?.. Again since my head was telling me tha cables are the problems, this time i took the 700w PSU sata and power cords and use them on the 500W newpower PSU. I had a very big surprise . I saw a magical smoke comming from my HDD.

My 1st question is: arent the cables the same ? on all PSUs ? or.. what i did wrong ? right now i have o buy a new power cable and a new HDD to throw them on the i7 system.

My 2nd question is: i had a chance to insert the cable that powered the HDD, in a wrong hole in the PSU? I dont understand why the hdd burned when i took the coord from 700W psu and put it the 500W and toasted the HDD.

PS: one more thing, when i took the cord from the 500W computer and put into the 700W computer, that 700W computer the i7 , wouldnt even try to power the system, but when i .. took the 700 W cable and put into the i3 system on the 500w PSU , thats when the magical smoke happend. Now im worried if i damaged my 700 W somehow. I dont even know from where to buy a psu cable or what kind of psu cable.. orrrr uh.. i really am worried i dont know what to do.
 
This is kinda confusing. Are both PSUs modular? With the same cable connections? Did you just swap power cables or did you hook up the HDD to the power from the 500 w. psu while the HDD was still installed in the one with the 700 w. psu? Or are you using a SATA to Molex power adapter?

I hope that the HDD was backed up?

both psus are modular, and i just swaped those modular cables between them, and i.. power off the HDD while it was working , unplugin it on i7 , and then put it on i3 system with the modular cable from the i7 psu, and i burned it :( the data was NOT backed up totally.... meanwhile i bough a new PSU 800 W corsair GS800 and a new WD 1 tb gb HDD :(
 


OK - Did you check to see if the wires and pins were the same polarity on the PSU end of both cables? I don't know if the PSU connections are industry standard or proprietary. If proprietary, that could be your problem, even though the cables seemed to fit.

a RL friend told me the same thing today, he thinks that the polarity might be switched and thats why i burned the HDD/ Atm i cannot check if they are reversed i can just google, because im running things on my computers :( but i have some questions.
1. the i3 rig is up and running for 24 hours now. Im wondering if he got damage somehow or he will get damage in future because of the HDD incident.
2. The i7 now, has a new PSU and a NEW hdd . I also am wondering the same thing. He might have problems in future ? because he was the first the rejected the HDD.
 


I seriously doubt that either computer was harmed by the HDD. PSUs have built in over current protection and the data cables are an industry standard so no way to mess that connection up. The HDD also has built in protective circuits. Fzabkar has indicated the probable source of the "Magic Smoke", above.

Indeed , they were different lol i checked ! WHY THE ..... :( oh god.. i thought it must be a standard or smth... :( Same holes , same shape, perfect trap :(


BUT ! before i burn that HDD, why the i7 system refused turn on ? and why the i3 system accepted the hdd and could work normally with it ?
