I'm getting a "geforce 7800gt video card, GIGABYTE GA-K8NE, and AMD Sempron 64 2800+ soon and I'm wondering if I should stick with my current power supply. The wattage is 580W, but I've been hearing that wattage doesn't make the power supply "decent", but rather something else. (input/output voltage levels?)
Anyways, here's the one I'm using now and it's been working fine for nearly a year:
If that's no good, then is this one worthy enough to keep things running smooth and safe?:
What about this one?
^ it's got the dual 12V and it costs about $89 . Is it worth it?
any help is greatly appreciated.
Yea, allot of people have been talking "sh*t" about the demon ps, but I haven't seen any problems at all. I guess a lot of them were bad, but mine was ok. Maybe it's because I'm using a Power strip made by Monster. It filters the electric current sent through it so that it's clean. Cleaner power keeps the computer's parts running longer I hear.
I found this info on extremeoverclocking:
I don't have any exotic cooling, large disk arrays or flashing lights.Are 2 rails better than 1? Short answer = Yes. It depends on your system as to weather or not dual rails would actually be of any benefit. If yours is a simple system, with no exotic cooling, large disk arrays or flashing lights, then you would probably not benefit from dual rails.
Does PFC play a big role in protection? It corrects the power to run at maximum efficiecy...does this mean less hardware failure?
Here's one with PFC, Over Voltage Protection, and Overload Protection: http://www.newegg.com/Product/Produc...82E16817103924
The only thing is the rails are +12V1@18A, +12V2@15A...so it's around 480W.
