    Will the Corsair HX750 be Enough for My Build?

    I'm building a new system with the following parts. I thought it would be enough at first, but I forgot the GPU is factor-OCed by quite a bit, so I'm not really sure anymore =x

    PSU: Corsair HX-750
    Motherboard: MSI P67A-GD55 (B3) LGA1155
    CPU: Intel i5 2500k (I plan to OC this to 4.5GHz+
    Heatsink: Noctua NH-D14
    RAM: G.SKILL Ripjaws X Series 2x4G ddr3 1600
    GPU: 2x MSI N560GTX-Ti Hawk in SLI
    HDD: 1x samsung spinpoint F3 1tb, 2x WD Raptor WD740ADFD 74gb
    Sound Card: ASUS XONAR_DG 5.1

    Ventilation shouldn't be a concern to me since I'll get getting the HAF 932 Advance, but I'm just worried that my PSU wouldn't be enough for this system.

    Much thanks!

    Lol; yes. it'll be fine. 2 GTX 560 Ti's won't break 350W combined.. 400W maybe OC'd. A 2500K even OC'd won't break 120W. It's more than enough.

    Though; for the price... You can buy better PSUs now.. The HX is a solid PSU; but it's based on an older seasonic platform. (Not saying its bad, but for the price you can get another that's just as good or better).

    DH D14 is a bit overkill but to each their own.

    If you haven't bought the HDD's yet, get a single 128GB ish SSD instead of the raptors.. Trust me it'll be far faster (Crucial M4 or Intel SSD).

    I hate that Case choice btw :P. HAF cases.. Ugh.

    Consider an Asrock Extreme 3 Z68 or extreme 4 instead of your motherboard.. P67 is sorta dated now.. Though it's still usable for sure; Z68 (gen 3 specifically) allows you to upgrade later on with an Ivy Bridge chip, etc etc. Or consider a Gigabyte UD3H/UD3R.

    I bought the raptors 2 years ago, and the spin point last year, so I don't think I'll be purchasing any additional storage soon =S

    I don't see why people would buy a more expensive board to save room for future upgrade to Ivy Bridge when it uses the same socket. Given that I'll be OC-ing my 2500k, the difference shouldn't really be that great. Imo, I only consider it to be an upgrade when it changes socket types. Am I missing something here?

    Thanks for the input though, it made me less anxious =) But sadly, I've placed orders on all those parts already >.> I buy Corsair's PSU mainly for its warranty. This system was an upgrade from an e8400 system I built 2 years ago, and Corsair's PSU was pretty rock solid. =x

    fwiw, I was running the 2500k build in my sig on a 750w psu for a while, and it consumes about 20% more power than the one you are building.

    I wasn't aware this board was cheaper than This board. Lol. :P

    Shame you already bought all the parts.. SSD's weren't affected by the spin point last year. SSD's rip up all conventional HDD's.. It's a hugeeee difference.

    Depends how long the socket stays around for. I have an LGA775 board that regularly runs a mixture of P4s from 2.8 GHz up to a C2D 6300. I think Ivy Bridge is a 'tick' rather than a 'tock' so will be a slightly smaller speed bump but will be a process size reduction and therefore potentially more efficient and/or overclockable.

    Yep, its pretty much perfect for that..

    ...and nvidia certifies it for a pair of 560ti or even 570.
