PSU question for new build

[mappy357]

Hi guys, i'm building a new system and although i have most of the components down i need help with a couple of them, any good ideas and suggestions you guys might have are welcome! here's the current build:

Mobo gigabyte GA P35 S3L
CPU E6750
RAM 800 mhz DDR2 2gigs maybe 4
GC EVGA 8800GTS 320 DDR3 superclocked
SC Creative Audigy
HDD Hitachi 320G/16M
OD
PS
Casing Antec 900
Speaker Logitech X-230

as you can see, i have not decided on a specific optical drive yet. actually any dual layer dvdrw driver would do, if you guys know of any good, fast and afordable ones i'll apreciate your opinion

my main problem is the PSU, i need something that fits in the case without problem and allows room for upgrade in the future (in a year or more i'm considering adding a 8800 ultra or two, depending how affordable it is and how SLI performance jumps, another HDD, and a PCI tv tunner) i have a few PSUs in mind:

Antec true power quattro 850W
coolmaster real power M850W
OCZ Game X stream 700W
silverstone 750W (non modular)
seasonic M12 700W
thermaltake 850W tough power

as i understand it, going by wattage alone isn't wise, the Amps provided to the 12V rails and the stability of the PSU are just as important, and PSUs with less 12V rails is prefered, but i dont have much knowledge nor experience with PSUs so I'm kind of lost here.

Again, thanks for any help you guys can give me, and sorry for the lousy english, it is not my native language.

As for optical. Any Samsung, Lite-On, NEC on Newegg in the $30-$40 range would be just fine.


For a PSU, I can tell you already realize how important it is. I can tell you that you cannot go wrong with Seasonic, they are all I use. A little more pricey, but some of the best PSUs you can buy. I have the S12 650W from them, SUPER quiet and very reliable. Dropped $160 on it at Newegg. I chose this one because I too have the 320MB 8800GTS but I know I will eventually upgrade to either the 8800GTX or something more powerful in another year or so. I know that my PSU is more than capable of handling it. For the money I cannot reccommend a better PSU.

Hope that helps.

Thanks Deuce I had heard great things about Seasonic but I did not know if 700W is enough, but i see theat the specs of your system are very similar to what i want to build and you had the same considerations when you build your system, thanks a lot for your help!

My PSU is PC Power

Two PSU's that will serve you well are.

I second deuce pro-Seasonic stance. They are the most efficient PSU's I have seen, and I can't hear them when the computer is running.

Get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151028

You shouldn't need more than this, and it is more efficient.

PC Power is at Seasonic's level, but I have less experience with them. I can't speak against them.

thanks a lot guys, i think i will go with the seasonic. cant wait to assamble this one!

It surprises me that no one reads the specs on these things.
The PCPower is better, cheaper and has a better warranty

I don't care if that PSU is better and or cheaper. I know that the S12 is more than enough for my current and future needs and I really trust the manufacturer. Its more efficient and super quiet, and it makes me feel good knowing that the PSU that I have is probably not going to let me down. I do plan on taking this PSU along with me on my next build.
