This is my first post, and I have a few questions. Recently I purchased a Gigabyte GTX 980 Ti. My computer wouldn't boot, and my symptoms pointed to the PSU, so I purchased a new PSU and everything works.
1) Could anyone speculate why my 980 Ti wouldn't work with my old PSU? It was a Corsair HX650 Bronze-rated PSU I bought in late '09. Before the Gigabyte GTX 980 Ti, I had an EVGA Reference GTX 980, which worked fine. To describe the issue I was having: my PC would attempt to boot for a few second, nothing appears on the screen, and then it turned off (and repeats). After clearing my CMOS I managed to get into the BIOS, but after restarting after making changes in the BIOS, it would go back into a reboot cycle. Once every 10 or so reboots, it would work briefly, but my PC would turn off if tried t enter Windows.
2) On Newegg, I recently had to choose between the EVGA 1050W GS and the EVGA 1000W PS. The PS was on sale so it was the same price as the GS, and I figured having a Platinum rating was probably slightly more important than 50W. But after re-reading JonnyGuru's reviews, I noticed a couple things that made me think perhaps I ordered the wrong PSU. First thing, the GS performed near platinum ratings already, so the difference in efficiency between the GS and PS seems even more minimal than the difference of the 50W. Second, in the hot-testing, the GS seemed to have slightly better ripple suppression by 2-3 mV on the 12V and did slightly better in general on the minor rails. Could these differences be attributed to small variations in the testing, or PSU's themselves? For example, would some PS models have better ripple suppression than some GS models? Or am I just over-thinking things? I'm sure in the end, I'll never be able to put either PSU in a circumstance where I'll be wishing I had either advantage. My initial thinking was that the PS would maybe run quieter. But it's not often I upgrade PSU's, so I like making the right choice.
Thank you guys
