    Which PSU?

    I'm getting conflicting estimated wattage at ASUS & pcpartspicker

    Build

    Asus Maximus VII Gene
    i5 4430
    Asus GeForce GTX 760 2GB DirectCU II
    G.SKILL Trident X Series 16GB (2x8GB) DDR3 2400
    2 x HDD 2TB SATA 6.0Gb/s
    1 DRW

    Any recommendations?

    hi Noots, welcome to ROG.. anything 750wat + will do the job nicely, going above 1000wat is a waste of money,, If your thinking about doing water cooling go with a 1000wat, here's a couple of good psu's that will do the job.. If you want a nice clean build go for a fully modular psu, as you can keep your wiring down to only what you are going to be using..

    Corsair CS750M Modular 80 Plus Gold Power Supply
    Corsair HX850i 80 Plus Platinum 850W Power Supply

    I agree unless your running say a pair of kingpins and doing a lot of overclocking something like a seasonic 860 would do very nicely..

    NZXT X62 | Acer XB270HU | EVGA 1080 ti FTW3

    Secondary: R4BE | 4930K | G.SKILL 2400 16GB | Corsair AX 1500i
    Intel 730 240GB + 480GB | EVGA GTX780 ti sli kpe | Custom H20

    You don't need a 750W PSU for a single GPU system.
    Something like a Corsair HX650W or a Gold 650W Seasonic or EVGA PSU would be fine.
    Intel i7 8700K@ 5.2GHz (Delidded)
    ASUS Maximus X Hero (Bios 1801)
    NZXT Kraken X42
    G.Skill TridentZ@ 4000MHz CL16 2x8GB

    The absolute max power draw on your system is going to be in the 350-370W range...figure in PSU aging and you should get something in the area of 450-500W PSU. Your system should idle fairly low and the efficiency of PSU's drops considerably at the low end, so you do not want to over spec it. (I'm making the assumption you aren't going to want to add additional graphics cards in the future)

    A few suggestions on the system...de-spec the motherboard and RAM and up-spec the processor and graphics card. Also, a small SSD will perform much better than 2 HDD's in RAID, so I'd drop one of the HDD's and get a small SSD.

    Hmm, we see this "minimum PSU" often, just bad advice IMO, some upgrades you don't plan for and Christmas is coming. Get a 750W of good quality. You will be able to sleep nights knowing your PSU is overkill. The PSU will not be in question when troubleshooting. You can upgrade when the time comes. You will lose little when the computer is at idle and the PSU efficiency drops - you are using little power so it does not matter. PSU's generally run best at 80% (assuming a quality PSU) so a 500W will be fine for your rig - provided you do not add anything.
    Good advice on the SSD, nothing improves the feel of a computer more than a boot SSD with your current game on it.

    I haven't decided yet ... but I've been coveting a Lian lin for the past 7 years but always end up with a clunky Antec. Seriously looking at PC-V358A, but my pragmatic side is whispering Corsair Carbide CC-9011069.

    Thank you everyone for your input and advice. This is my 7th build since 2003, and hopefully it will be uneventful like all of the other ones.
