SO I find myself with to many choices really, so i figured maybe some with more knowledge then I could tilt my mind a certain direction twords the right power supply of what I need now and the future. Im looking for a psu that will work now of course but also will still be good if i decide to upgrade a few more things like another graphics card etc... anyway here is what I have now, **note I have tried the "power supply calculators" but those do not take into consideration 12V rails needed and such. So I would like something that can handle the card I have now, as well as maybe going sli in the near future as well as cpu, and mobo upgrade in the future. If your bored enough to look through what I have and find a psu for me (no more then $250) I would be very greatful!! I do have a few in mind but... unsure.... thanks for any help!!!!

Not a thing wrong with your current PSU. It has 56 amps combined output on the 12V rails, more than enough. http://www.thermaltakeusa.com/Product.aspx?S=1207&ID=1507

Looking at the pic on Newegg it is a CWT OEM, same as the Corsair TX series (V1). The one time Thermaltake didn't cheap out on a power supply. I would keep it without a worry.

the only problem with my current one is this though.... all 4 of my 12v rails are only 18amps max, my new graphics card says minimum of 38amps on the 12v rail, and since the card only has 2 plugs im only putting 36 amps to it. :( I looked around to see if they make an adapter so i could plug 2 into one = two 12v cords into one type adapter but I was led to believe no such thing exsisted.... is this true? if so... I would like to get a power supply that is partially or fully modular, and has the power for my card and sli in the future :)

corsair has been having great problems with their psu's lately from what I gather....

You are not quit getting this. The card itself does not require 38 amps on the 12V rail, that is a requirement for the whole system (which is why amp recommendations are bogus anyway, how would they know what else is in your system). Your current PSU is more than enough for your setup. It is not like the PSU actually has 4 rails anyway. 4 "virtual" rails maybe.

Any links on that? I am curious.

I always thought Corsair rarely makes crap psu.

Your current PSU will run your graphics card just fine. The PSU's from Corsair have usually been good, but the Builder series seems to be not quite as good as their others. Granted this is anecdotal, go for the Professional or the Enthusiast series power supplies from Corsair for best results. JonnyGuru.com seems to still like Corsair, along with most other review sites, like PC Per and HardOCP.

Thanks for the heads up on which range to choose from Corsair. I usually use Thermaltake if i am on budget and i am satisfied with it.

Not to pick on Thermaltake (I have one in the system I am typing this on), but that is one brand you have to watch out for. Their PSUs range from pretty good to bottomfeeder garbage (Purepower) that shouldn't be put in a system. That is a problem with many brands, even some of the "premium" brands. Antec has had their share of mediocre offerings, Enermax, and Coolermaster as well.

I tend to be lazy when I post here. The only two brands I give blanket recommendations for are Corsair and Seasonic, as they don't have any "bad" PSUs in their line up (overpriced maybe). Almost any other brand, you have to look up specs on each individual offering, find reviews on it, find out who built it, etc. Even the lowly CX430 isn't a bad PSU, mediocre maybe if you look at the idiot reviews on Newegg. 2 builds and one repower so far with that sub $30 PSU, and no complaints.

Here is a list, it is not perfect, but gives a general rundown of what to trust, and what to avoid. It is updated. http://www.eggxpert.com/forums/thread/323050.aspx

and my main point above is you don't see Seasonics and Corsairs on the Tier4 or Tier5 list. They are usually a safe bet.

Interesting, my gaming rig psu is in tier 3 which is a thermaltake litepower 500w. I thought OCZ made crap psu and also they didn't add Shaw psu, which they are the crappiest one. The Shaw fried my friends graphics card and it is the cheapest one you can get in Australia.

well... judging from all the posts... maybe ill hold off then buying a new psu, I still dont quite understand how my current one is "ok" to run though lol, from what the details on the newegg specs say about my card, and what the specs are on my current psu. also yes it does actually have 4 12v rails (not virtual) and as far as the corsair psu's that I was talking about, i had found that a pretty decent chunk of people all had the same problems (in reviews) from alot of different sites... newegg, xoxcide, toms... etc that quite a few only lasted less then a year before dying, or they came doa. I myself like thermaltake... just because my current one has lasted me 3+ years now and I have "beat the hell outa it" so to speak lol... and still is runnin like the day I bought it with no problems.
