    what would the power draw be on the systems below.. im thinking of using a single PSU using a Phanteks Power splitter, to allow me to remove the SFX PSU and cables and add another Fan

    PC1
    Intel i7 8700k
    Gigabyte Z370N ITX Motherboard
    16gb DDR4 3000mhz
    GTX1060 6gb
    2x 128gb M.2
    3x 256gb ssd
    1x 385gb ssd
    Superflower 550w gold PSU

    PC2
    Intel Hex Core Xeon E5-2643 v3 @3.4ghz
    Asus X99-MWS Matx Workstation Motherboard
    64gb 2133mhz DDR4 ECC Ram
    GTX1050ti
    256gb m.2
    1tb HDD
    Silverstone 500w Gold SFF PSU

    Case. Phanteks Mini-XL

    That Xeon can be rather hungry, so would count that PC needing fair 200W.

    Anyway if you're intending running wires from other PC to another if there's anykind notable distance between them, then wiring should be thicker than standard thickness to minimize voltage losses.

    You'll need 24 pin Y cable and whatever CPU (4/8pin) auxiliary cables, then wire the pwr pins in parallel to the power switch cable. Should work lovely

    ok you guys are missing the point, I can get the power splitter no worries , I juist need to no the wattage for a single psu

    Are you going to use them both as gaming PC or will that second be purely some HTPC or work PC?
    Especially if you're going to upgrade graphics cards that can cause notable power draw increase to current.
    So tell more precisely about what you're going to use both of those PCs.

    I’d say at full consumption you'd be looking at around 800 Watts.

    Processors are 95w and 135w respectively
    Graphics cards are 120w and 75w*

    So you're at 425w there giving 125w for everything else. Fair enough, everything else doesn't draw much power but I'd say you're far too close.

    *These are just rough figures pulled from Google so don't take them as gospel. Just giving you a rough idea.

    Worst GTX 1060 actually peak at 140W
    https://www.techpowerup.com/reviews/ASUS/GTX_1060_STRIX_OC/24.html
    But with only one HDD there and with mATX and especially ITX motherboards being more frugal 50W less should be more than enough for other parts.

    Also simultaneous gaming on both is rather unlikely and anyway would't load CPUs fully.
    Some heavily multithreaded rendering loading CPUs again wouldn't do much to GPUs.
    So 750W would be easily enough.
    Same for 650W unless both PCs are going to run simultaneous 100% CPU+GPU load.
