Shivarn Posted December 1, 2010 Share Posted December 1, 2010 Ok, so i recently bought myself a Corsair TX650 power supply for my computer. The reason was my last psu which had about 850watts was at its peak of life left over. It didnt have enough to a HD3870 x2 radeon gfx card. Ive had this computer for 3 years now. I also bought a new card Radeon HD 5770 to replace my old one. The issue is after connection my PSU to my computer, My PC just randomly shuts down at a certain time when running a task which requires to either to use the graphics card or even leaving the computer on for a while. I had tried different solutions such as possibly using the cable converter which came with the graphic card which lets u connect 2 4 pin power port cables, and it did the same thing. I also tried using the PSU PCI-E cable for the graphic card and still did the same thing. I tried many different things like removing extra parts such as 1 slot of ram, my wireless adapter, even my cd rom drive. no luck. I have noticed though, majority of the time, its because its running a process which requires more power usage on the MB and GFX card. Once i unplug the GFX card and use standard integrated, it works fine which is bringing me to a point stating that maybe the gfx card is overpowering the psu which is causing the whole system to randomly shut down. Another possibility i think is maybe i did my wiring wrong, although I've checked it and triple checked it, I don't know whether I'm missing something or connected a wire wrong or something. Although i did only buy the product after doing a massive amount of PSU calculations and whether or not 650watts is enough for my system, and almost every answer i got back was that it should be more then enough. But like i mentioned, after i tested it, it didnt sound like it was enough. I havent tried reverting back to my 850w PSU yet because I havent got access to it as i left it at my brothers house. But I hope someone can help me. Maybe im missing something. http://img87.imageshack.us/i/img0076c0.jpg/ http://img87.imageshack.us/i/img0077te.jpg/ http://img89.imageshack.us/i/img0078e0.jpg/ http://img715.imageshack.us/i/img0079yy.jpg/ Hope this also helps.
