My home built PC has a Corsair CMPSU-850TX PS. It has an excessive amount of cables, which I can't imagine in what configuration they would all be used, but only two of those cables are for SATA, with about four connectors each. Because of that, I have to use one of the cables for the optical drives, and the other one for the hard drives (all in a chain), but I was replacing one of them yesterday and it seemed to me that three hard drives getting power from the same cable is a little too much. Two months ago a Western Digital Caviar Black drive that wasn't even two years old died a sudden death making me lose lots of family videos that I hadn't had time to edit yet, so I'm wondering if this had anything to do with it.
Does this make technical sense, does it matter that 3 drives are fed in a chain from the same cable, or is it the same as using 3 different cables? I mean, does the first drive in the chain suck most of the power, leaving less power to the second one, and the same for the second one to the third one?
If I have to use three different cables, are those adapters from regular connectors (sorry, I don't know the exact name) to SATA connectors safe for hard drives? If not, what PSUs in the market come with several cables with SATA connectors?
One last question. Even though this was a highly rated PSU when I bought it over two years ago, I'm thinking of upgrading my PC with a new motherboard, CPU and memory, not the hard drives because they are brand new. But I'm wondering, are high quality PSUs supposed to last several years and it would be safe to leave this one in, or should I buy a new one?
Thanks,
Sebastian
