I currently use a Delta 550W PSU with my core 2 quad q9400, 4870 1gb, x-fi titanium, 2 500gb hdd & a DVD writer. Also I have 5 120mm fans running with it & without any problems. But I was just thinking of upgrading to a new GPU at the end of this year, it might be a gtx 570 or 580.
So my question is, will my Delta 550W be able to pull a GTX 570?
Asking the question because, I have seen the geforce website saying that minimum PSU wattage is 550W for 570. So if my delta can pull it off, then I would not go for a new PSU, as my delta one is still new & has warranty. But if I have to get a PSU, now will be the time, so gotta know fast.
Also, can anyone tell me, how good is the Corsair TX650W PSU? I found someone selling via Arif vai, which was brought from abroad, 1 yr used with a regular office PC & according to them, looks like new, selling at 6k. Can anyone tell me if it would be safe to take that PSU? longevity & stability to be considered, remembering I have an UPS running well. Asking this because, if it is good enough, I may take it, which will give me the option to think for a GTX 580.
