So i was on my computer today playing Dead Space when all of a sudden it just shuts off by itself. I know I accidentally short-circuited my motherboard a few months ago (forgot to install mobo standoffs to prevent the mobo from touching the mobo tray) so I thought maybe the mobo died... but I decided to check the PSU anyways. I googled how to test my psu and found the paperclip method (remove psu, turn off power, connect to wall socket, insert one end of paperclip into green wire on 24-pin ATX cable and the other end into the adjacent black wire, turn psu on, check to see if psu fan is spinning) so i tried that but the fan did not spin. I just sent an RMA request online to Corsair (i have a 620HX) but the thing is i'm going to need a replacement unit in under 10 days because I go back to college soon. I can't find the newegg receipt for the psu (i think i might have sent it in for a mail-in rebate on something), and on top of that the barcode on the PSU box is missing because I used that for a MIR as well... so am I still able to do the RMA or not? Also, has anyone had past experience with Corsair RMA's? How long do they usually take? Do you think I'll be able to request express shipping? Any advice is appreciated, really. I just want my PC to be up and running very soon
