Will the Seasonic M12 700 Watt be enough for my build?

Just a quick PS question:

I've been researching my components for a while now and was all set to go with Seasonic's M12 700 Watt Modular Power Supply. However, I just read some information on www.slizone.com that stated that this PS was not sufficient to run 2 8800 GTX's (superclocked) in SLI.

While I don't plan on going with SLI right from the start, I would like to have the option to do so in the future without purchasing a different power supply.

Can anyone assist me in picking a better choice of a power supply? Or do you think that this one will be enough to run the GTX's in SLI? (The website stated that it could only run the GTS in SLI...)

My 3 criteria for picking one out:

1. Must fit neatly in the Antec P182 without having to remove the bottom drive cage (seeing that I already can't use the top cage due to the size of the 8800 GTX...)

2. Must be modular.

3. The closer to silent, the better!

Here's the build that I'm currently looking at:

Case: Antec P182 SE
Mobo: Leaning towards EVGA nForce 680i SLI
CPU: Core 2 Duo E6700 2.67 GHz (may upgrade this selection after the July 22 price drop)
CPU Cooling: Noctua NH-U12F/Artic Silver 5 (Already Purchased)
RAM: Debating on using either 4GB of Corsair XMS DDR2-800 (4x1MB) or 4 GB of Patriot DDR2-800 (2x2GB)
Power Supply: SeaSonic M12 700 Watt ???
Hard Drive 1: WD Raptor - 150 GB
Hard Drive 2: WD Caviar SE16 - 320 GB
Video Card: EVGA 768-P2-N835-AR GeForce 8800GTX 768MB GDDR3 PCI Express x16 SUPERCLOCKED
Sound Card: Sound Blaster X-Fi XtremeGamer Fatal1ty
DVD/RW and DVD Drives: 1 DVD and 1 DVD/RW
Floppy/7-in-1 Card Reader:Mitsumi
Operating System:Leaning towards 64-bit Vista

Thanks for any help you can provide!

More about will seasonic watt build
  1. That's what I had gathered from the research that I did, but the SLIzone website made me second guess myself. Thanks for the reassurance! :D
  2. I would opt for XP pro. I tried Vista Ultimate and it stank. I would consider going from vista ultimate to windows 2000 an "upgrade"
  3. I would opt for XP 64bit or vista 64bit as you will be sick when you only see 2.5~3.3GB's of RAM. With your GPU it will be below 3GB's on 32bit.
  4. On your question of superclocked GTX just check ultra sli as thats what a ultra is more or less an OC'ed GTX. Here is the lowest watt PSU you should use.

    My question would be not if the seasonic can handle two superclocked GTX's but will it handle 1 G92 comming this xmas?
  5. Have you thought about the PC P&C 750? (not modular) I love mine and it will do 2 GTX in SLI. I didnt have to remove the lower fan either.
    Not sure what prices are like on your P182SE and the Seasonic, but you could switch to the new Antec P190 which comes with 1200watts - that should run 2 GTX's in SLI, I think. hehe
    182SE $200 - 220
    Seasonic $200 - 210
    Total = $400 - 420
    Egg has the P190 for $450.00

    But the 182SE is nice looking.
  6. Yeah, I looked into the P&C 750 and found it to be a really nice looking PS with very good specs. However, I'm doing my first ever build and am trying to make things easier and cleaner by going with a modular PS.

    The Antec P190 is a very good suggestion. I saw that it just appeared on NewEgg yesterday or the day before and it would actually only cost me about $80 or so more (with shipping factored in) to purchase it rather than the P182 SE and the Seasonic PS. I don't know, though...I'm a bit turned off by the look of it as well as the thought of dealing with two non-modular power supply's. I've read conflicting reviews of the P190. One said to use one PS for the Mobo and Video Card's and another review said to use one PS for the Mobo/accessories and the other for the drives. :?:

    Maybe if Amazon doesn't come through with my P182 SE, I may consider the P190 in more depth. (I ordered my case on May 5th for $188 plus free shipping and despite the website always saying that it's 'in stock' it still hasn't been shipped as of May 25th!)
  7. Good point about the G92. I hadn't even thought about that! Since I'm trying to be as future proof as possible (hence my choice of 64-bit Vista), I need to take that into consideration.

    It's funny, because I've noticed that most people around this forum consider future-proofing to be looking out for the next 2-3 years but my current computer (Dell's top-of-the-line model as of December of 1999), has lasted me nearly 8 years with only a couple video card and some additional RAM as upgrades. I'm hoping to get another 8 with minimal upgrades (video card/CPU) out of this rig.
  8. If you want the new system to last you may also want to put off the mobo purchase until the P35's and PCI-E 2.0 which should release next month.
  9. Thanks for the sound advice, Elbert. I'll definately wait and see what new mobo selections and technology are released in the next month or two. I've waited this long, I can wait some more! (I know there's some that say if you use that philosophy you'll always be waiting for something, but oh well!) :D
  10. True that philosophy may cause you to keep waiting but the other side of the coin is it take a rich man to buy on whelm. I'm no rich man is what I say.
