I'm building a new PC, with these specifications, but I'm unsure of which kind of power supply I need and how many watts.


    NZXT S340 WHITE MID TOWER CASE
    INTEL CORE I5-7600 3,50GHZ BOXED CPU
    ASUS STRIX Z270H GAMING
    Samsung 850 EVO 250GB 2.5" SSD
    WD Desktop Black 1TB - WD1002FAEX
    HyperX Fury DDR4 2133MHz 2x4GB
    ASUS Geforce GTX 780 3GB PhysX CUDA(Got this from a friend)

    Upcomming upgrades:
    HUE+
    NZXT KRAKEN X62 AIO 280MM LIQUID COOLER
    5 x NZXT Aer RGB - 120 mm(OR 140 - Not sure..)
    About 4 x NZXT HUE+ LED Strips



If possible it would be nice to be able to switch the cable colors out.

Normally, a GTX780 needs a 6 pin pcie connector for 75w, a 8 pin connector for 150w and the 75w power from the pcie slot for a max of 300w.

Add to that, what you need for cpu and other stuff.
I think the 750w listed in the chart may be overstated.

That said,
I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

The corsair rm750 would be excellent.

Sorry forgot to mention. I got the 780 from a friend for free, since he believed it would otherwise be a waste of money to sell it. How much does GTX780 itself need of watt?





I got the GTX780 for free, from a good friend. Thanks I'll check your links out. Do the 780 eat a lot of watt?


Would CORSAIR PSU RM750X 750W be a good choice?
