my psu seems to have burnt out my mobo, 3 harddrives, and my cpu. luckily my main drive seems to have survived. the mx 100 however did not and i seem to have identified the point of failure and just need some assistance in identifying the chip as well as how i might be able to repair it. im a newb when it comes to this stuff so please explain things to me in detail when ti comes to testing and repair. i saw the post of the person whos mx100 failed however he seemed to have a less obvious problem than i do. any help is greatly appreciated. thank you. pictures below

I believe it's a power IC. Probably this one: https://www.aliexpress.com/item/32532393392.html

But, don't be surprised if there are other burned out components.

There are some errors in that thread, so make sure you read it all.

The visibly damaged chip is a TLV62080. Note that these PCBs are poorly protected (or not protected at all), so an overvoltage tends to do a lot of damage, most of which isn't visible.

BTW, judging by the damage in your other threads, you appear to have done this:

Warning: do not interchange modular PSU cables:

That doesn't look right.

"JAGR" is a TI "5-V, 1:1 (SPST), 2-channel general-purpose analog switch", p/n TS5A2066DCUR.

i believe the unit that is visibly burnt is an rau unit. not totally sure on that though. was hoping for some confirmation. thank u guys for responding i appreciate it

I was looking at the item listing title which said it was RAU marked (which is what I searched for). I see that the picture is different, I never actually looked at the photo on the aliexpress listing. Looks like the component can be obtained directly from Texas Instruments here: http://www.ti.com/product/TLV62080/samp ... #samplebuy

i would be lucky if that is the only thing fried. do u think this can be done with a soldering iron and solder paste? or do i have to use a hot air gun?

which one of those should i buy? im a little confused because they have different model numbers

what is the difference between the TLV62080DSGR and the TLV62080DSGT?
