I am organizing the parts for my dream gaming pc. I know nothing about power supplies or how to decide which wattage is ideal. I plan on overclocking as I am also buying a watercooled case. Here are the parts I plan on buying, feel free to suggest better ones :D 

ASUS Maximus V EXTREME LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Extended ATX Intel Motherboard

EVGA 02G-P4-2680-KR GeForce GTX 680 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card

Intel Core i7-3770K Ivy Bridge 3.5GHz (3.9GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000
BX80637I73770K

Refurbished: Creative Sound Blaster X-Fi Titanium Fatal1ty Professional 70SB088600002-8 7.1 Channels PCI Express x1 Interface Sound Card

Z-Machine LQ1000 Water Cooled Enclosure

Thanks SOO MUCH guys. This is my first build.

:)  This is what I would personally purchase...80+ GOLD and it's fully modular for the price of $109.99; quite a steal!


Thanks, but is this enough for an ivy bridge processor, a high end gpu, and possibly another high end gpu down the line? Would a 1000w modular one be too much/hurt my performance?

Unless you're planning to Quad SLI your 680's, there's no need to get a 1000w PSU :) 

650w will run any Single-GPU card on the market with an OC'd CPU.

**EDIT**

Actually, if you're planning to SLI GTX680's, here's my recommendation -

http://www.newegg.com/Product/Product.aspx?Item=N82E168... 10% off at the moment along with a $20 rebate bringing the total cost near $100 :)  very nice deal at the moment!

Thanks but can you give me the title and/or product number of it because the kind of network I'm on currently blocks redirects so linking to it won't work. Thanks again :D

Corsair TX850V2 PSU if you're wanting to SLI GTX680's

Seasonic X Series 650w PSU if you just want a single GTX680 :)

Seasonic X Series 850w PSU. It's quite expensive at $189, but that's what you pay for in order to get 80+ GOLD efficiency paired with a fully modular interface :) 

It's still worth it IMO, you get the Seasonic brand and all the other bells and whistles along with it.

one more question while i have such an expert :p 

i am water cooling, using a DD12V-D5 Pump Variable Speed by Laing. it says it uses 4 pin molex connectors, I dont see any on my future motherboard, Asus Maximus V Extreme, is that the same as a four pin fan header? it has plenty of those and I believe they are 12V. or can a molex connector or two, or three preferrably, be found on a psu? thanks soooo much

Very nice choice of pump!

Anyways, Molex is a plug that is attached to your PSU, not motherboard, so you shouldn't worry one bit. From the looks of it, the 850w Seasonic unit I listed comes with 4 Molex plugs :)

Hi - I agree with moochan on Seasonic X650 (i just installed mine 3 days ago), but for the next 24 hrs($40 promo code expires) you can get
the Seasonic X750 Gold for $109.99 at
