flipswitch Posted March 1, 2013 Share Posted March 1, 2013 Hi All - new member here. Coming at you with one that completely baffles me. So let's begin the story: I had a TR2 RX 750W for about 3 years, two weeks ago, I press the power button (pc was completely shut down) and BANG! (literally) - then (naturally) the PC refused to turn on. Sniffed around - smelled like something burned inside the PSU. So I pick up a spare Codegen (can't see a model # on it) 475W from my spares pile, slap it in (no gfx card, etc), and it works fine. So I shopped around a bit and settled on a Corsair AX850. Installed the Corsair, powered up, everything went absolutely smoothly. (Everything - all components reconnected). Next evening when I get home, PC refuses to turn on. A little red LED on my motherboard was on (it's usually on once the PSU is connected), and nothing smelled burnt. So I pulled out the PSU (completely out of case, not connected to anything) and did the paperclip test - it came on for less than a second (fan only just started to spin) and came back off. Been trying to get through to Corsair TS, but figured I could write a post in the meanwhile. Right now, I have an Omega 600W (another spare I found) in the PC, and everything's running just fine (but no PCIE conn). Anyone have any ideas? Is my PC allergic to high end power supplies? :/ Let me know if more detail is needed. I really hope someone has an idea of what's going on. I think just not knowing is killing me more than losing the PSU(s? - kinda hoping the Corsair magically starts working ) Link to comment Share on other sites More sharing options...
flipswitch Posted March 2, 2013 Author Share Posted March 2, 2013 Just btw: -No overclocking -Running through a Tripp Lite SMART1000LCD 1000VA (UPS & Voltage Regulation) -And now to eliminate the PCI-E (because the lower end PSU's didn't have the connector) I've fashioned a dual molex to PCI-E adapter and hooked the Radeon back up; running through it about 15 mins now, no problems. (Running through the Omega) Any ideas guys? Link to comment Share on other sites More sharing options...
flipswitch Posted March 2, 2013 Author Share Posted March 2, 2013 Btw - sleeping, hibernating, restarting and cold booting working fine. And all voltages look fine from AIDA64 afaik CPU Core - 1.17-1.36V CPU VID - 1.18-1.2xV VBAT Battery - 3.22V DIMM - 1.58V North Bridge Core - 1.14V North Bridge VID - 1.13V South Bridge Core - 1.20V GPU - 0.95V GPU VRM - 0.95V / 2.00A GPU +12 - 11.94V Link to comment Share on other sites More sharing options...
peanutz94 Posted March 3, 2013 Share Posted March 3, 2013 Try using it without your UPS. Corsair recommends a pure sign wave UPS and that unit you have is not. So it may cause issues with the PSU. Really i believe all your issues are just pure coincidence. What are the voltages for your Corsair PSu in the BIOS. Just need the 12v,5v and 3.3v readings. everything else is irrelevant.
