Hey Everyone
So i made the classic ignorance error of mixing cables between power supplies. I used cables from a corsair rmx550 with a thermaltake tough power XT 875w. The result was when I tried to initial power on, the system flashed on then off, then on then off. I fried my h110i, and 2 of my seagate barracuda's now have a no spin condition. Based on reading and testing Iam assuming that I blew the diode/s but wanted to double check iam not a complete idiot and check some things over.
So the idea Iam getting with the diodes is they create temporary shorts to ground in the event of over voltage spikes ( e.g. supply instability, initial powerup etc) however in the event of sustained over voltage they can blow, and at rest will be a constant short to ground. In this event, doing continuity tests between input pins and output pins I should be seeing total or near total continuity to ground, right?
My theory was always that the 12v and 5v got switched, in theory in this event, 5v to the 12v diode would produce nada, no shorts etc since insufficient voltage. Howeer 12v to 5v line should result in the diode 'blowing' and shorting to ground.
Testing what I assume is the 12v diode (it tracks to the 12v pins), I still get a diode reading, meanwhile the 5v diode ( marked AE and has continuity to 5v pins and common) is a total short.
So, In order to recover my data, in theory all I need to do is, desolder the 5v diode then use a truthworthy supply etc to pull the data off the drives.
Am I on the right track here or am I way off? Also from reading I know it can be a real pain to desolder surface mount components with a solder iron vs hot air station. and guess which I have :\ Can supply photos of the area Iam looking at if interested.
