Saefir Posted June 6, 2014 Share Posted June 6, 2014 Hi! So I assembled a new computer with the specs: EVGA GeForce GTX 780 Ti Superclocked ACX 3GB Video Card Intel Core i7 4770K Quad Core LGA 1150 3.5GHz CPU Processor Samsung 840 EVO 120GB 2.5" SATA III SSD MSI Z97 Gaming 5 Intel LGA 1150 ATX Motherboard Corsair Vengeance LP 8GB (2x 4GB) DDR3 1600MHz Memory Corsair RM-750 80 Plus Gold Modular Power Supply WD 1TB Blue 3.5” 7200RPM SATA3 Hard Drive Cooler Master Hyper 212 EVO CPU Cooler After I'd assembled it, it worked absolutely perfectly for one day but then, on the second day, the computer wouldn't start from the power button on the case. So I tried turning it on via the power supply switch and the computer would start up for 3-4 seconds before shutting off completely. I'm pretty certain it's the PSU since I did the paper-clip test and the fan only turned for 2 seconds before coming to a halt. But still, is it possible for someone to tell me whether or not it really is the PSU, and if it is do I send it back to the retailer or corsair itself. Also, if I do send it to corsair would I have to pay for shipping and would corsair send me a replacement while my PSU is being shipped or would they have to receive it, test it and then send me a new one/ fixed one? Any help would be awesome :)! Link to comment Share on other sites More sharing options...
wytnyt Posted June 6, 2014 Share Posted June 6, 2014 id recheck all your psu connections,if your psu is like mine,anytime current is interrupted,it will power on 3-4 seconds and then restart normally,,,thats as far as i can advise on this,sorry but in the event of a replacement happens,your quickest option would be thru the vendor where bought. if going via Corsair and under 30 days then they would pay to send you another new one..

jameyscott Posted June 6, 2014 Share Posted June 6, 2014 If I recall correctlly, the RM series does not spin up the fan on start up. So, that isn't exactly the best test. Have you looked at the voltages with a DMM (Digital Multimeter) ? Link to comment Share on other sites More sharing options...
Saefir Posted June 6, 2014 Author Share Posted June 6, 2014 I disconnected and connected the wires again (I've done it a few time before) and it still doesn't work.... Also I don't have a DMM, is there any other way to test it perhaps? BTW thanks for the quick responses :)! Link to comment Share on other sites More sharing options...
jameyscott Posted June 6, 2014 Share Posted June 6, 2014 Hmm. Well, that happened to a previous build of mine, but it ended up being the motherboard (and took the CPU with it) So, that's a possibility. Any chance you have an extra PSU laying around or have a friend that would let you test your system with their PSU? Link to comment Share on other sites More sharing options...
Saefir Posted June 6, 2014 Author Share Posted June 6, 2014 Hmmm I'm thinking it may be a motherboard issue now... Idk... Link to comment Share on other sites More sharing options...
Saefir Posted June 6, 2014 Author Share Posted June 6, 2014 Okay found out what it was. Apparently it was the PSU in the end... one of the coils inside it burnt up and destroyed for some reason 0-0? Anyway it seems, according to my friend's electrician dad, that because of this broken coil, the PSU provides just enough power for the motherboard to start up but when it comes to the CPU and the OS the PSU can't handle it and then shuts down. I'm kinda happy it was the PSU and not the motherboard but thanks for your help guys :)! Link to comment Share on other sites More sharing options...
jameyscott Posted June 6, 2014 Share Posted June 6, 2014 I'm glad you found your issue! It's too bad it wasn't as simple as a slightly disconnected cable. =/ Corsair's RMA process is very simple though, so you should be back up and running quickly!

Saefir Posted June 6, 2014 Author Share Posted June 6, 2014 Did he open up the PSU? Nah he just smelt the back of it and said it was really burnt. Then he ran it through his own DMM to find out it wasn't putting out enough volts for the computer to run. Link to comment Share on other sites More sharing options...
