Ok, I have an old 350 W PS that came with my case (Yeah, it's actually not a junker despite what I've heard from other people about in-case PSes). Anyways, I am going to be buying a new one soon since 350 W just doesn't cut it anymore. I was looking at the BFG 7800 GS and someone said to make sure you have a 12 volt rail with 26 amps. Now I see on the side of mine and the ones I've looked at what are the 12v ones, and I want to know, which one is the volt I should look at to see how much it has. Additionally, if it's a dual (Or Triple) 12v and one is 18 amps and the other is 20, is that a total of 38 or something else?
Sorry, but these power supplies are very confusing to me. I rarely ever buy them, and these are the reasons why. Also, why are some of the ones like Antecs $170 and they're only 550 W when you can buy a 700 W of a cheaper brand (Thermaltake) for $140 or so? Is it something in the insides of the PS that I won't openly see (Like aforementioned 12v rails and other redundant features and efficiencies)? Are they really worth the extra money and would I notice a difference from a cheaper more watt PS to the more expensive slightly lower watt (maybe 100-150 W lower) PSes?
Thanks for any help, I'm totally clueless in the PS department, all I really know is more watts is more power. I hate to say, but previously I've wanted to follow the "Just buy the more expensive one, it's probably better for some reason I don't know or understand."
The power supplys from companies like antec and enermax are the realieble and stable kind. Of course you can buy one from thermaltake but I have heard some bad stories about those. Anyway antec is a really good brand and a 500W ore higher will serve you well.
Ps. Sine you are looking at a 7800GS im guessing you got AGP, why not take a look at the X1950PRO?
I'd go with an X1950 Pro as well, if you're on AGP. If you're not on AGP then there's no real reason to be thinking about a 7800GS anyway.
Well the thing is my price goes from $189 (with mail-in rebate) to $290 with no rebate. Quite a heafty chunk of change more and I still need a PS which is going to run me in the $100 range.
I take what n0e says way too seriously

Not a bad way of thinking,as long as the more expensive one has less bling. Nice paintjobs and gold plated fangrills are pretty useless.:)
Yeah, I could care less how it looks if it powers all my stuff and it isn't too noisy or hot.
Mine is behind 3mm of aluminium, so looking good is pointless. It is quite nice though...purty blackness. :p
But back to the topic, how can I tell about the 12v rails when there are two of them or three?
I don't know the answer, but to be honest the rule that you've always gone by still applies - if you pay for a decent PSU, you get a decent PSU, and it'll work.
Alright, I suppose I'll just do that then. Really wish I knew though lol. Kinda feel stupid just buying and hoping it does what I want. Thanks for the help though.
