Hello,

For ~6yrs my main rig has had a Seasonic X750 power supply, everything had seemed fine. Last week I replaced my old HD7950 with a RX-580 and at first everything seemed fine, then yesterday computer wouldn't boot, after disconnecting power / reconnecting.. it finally started (it would fail by spinning up fans and then shutting off).. there was a RED led on the video card near power connector lit ..

today it also wouldn't boot.. and after messing with it awhile it was still no go.. I dug out a old pc and put card in that and it booted..

so finally I replaced the Seasonic X750 psu with a old Corsair TX650W power supply and it works now...

the seasonic did work the first 2 days?? so what the heck is going on has the Seasonic died 2 days after getting new card??

I think the PSU is still under warranty ... seasonic says X series bought before sept 2012 have a 5 yr warranty but after have 7 and I bought mine from newegg 9/29/2012..

thoughts? (and yes I reseatted cables / card multiple times it just won't work with the Seasonic anymore

updating this.. I sent seasonic my X750 on rma , they quickly sent a replacement which was a revised version that uses different cables (i received on Friday) I emailed them about my predicament on not having appropriate cables for the RMA unit last night, and they responded earlier today with confirmation they will ship me cables for the km3 model they sent me.

hopefully when new cables arrive i will be good to go ... all in all since sometimes things get messed up along the way, seasonic is very responsive and helpful in trying to resolve the issue..

good company.. good support..

will update with results when new cables arrive.

Hello,

Thank you for your comment and feedback. We will indeed ship you a set of cables asap in order for you to be able to use your replacement. We will keep you updated by email as soon as it's shipped.

Best regards,
 
A cable set has been shipped and I have been told that one cable arrived damaged (loose cable?) if I understood well so we sent this day a new replacement for the said cable to be received within 24-48H.

Best regards,
 
happily I didn't post the "draft" that was saved here last night... because I was ****ing furious...

thank you for sending a replacement 24pin cable.. I'll admit that I was /am a bit irritated by the tone of the 1st reply i got about that cable.. since I'd already wasted 1/2 hour trying to install the RMA power-supply before I realized the cables where different.. this time when I finally got time do deal with this I decided to test the power supply / cables on my table.. and lo and behold a pin was out on the 24pin cable..

I sent email with situation / pic of issue

blah blah without trying to sandbag Seasonic / anyone too much.. they basically asked what i did to f*** up the cable.. AFAIK I didn't do nothin' to the cable.. that is how it looked when i took the cables out of the UPS baggy they came...

from email...
I wonder how you damaged the cable we sent you, was by improper hard pulled?


In building my own pc's / building pc's for friends / family since mid 90s, I ain't ever pulled a pin out of any power connector due to mishandling (I've had a few molex pins fall out..but molex sucks and that is kinda what molex does?).. maybe i did somehow do it? maybe not... far as I know i didn't and 100% I know i didn't mishandle it because all i did was take twist tie off after taking it out of box to try plugging it in to test power supply...

ultimately... I guess I can't complain too much as they are sending a new cable.. but I once again started to try to install the thing and again didn't.... but that email.. leaves a sour taste for me.. honestly ..

meh.... whatever.. when the 2nd cable shows up hopefully I'll actually install this thing.. 3rd times the charm perhaps?
