    Default Radeon RX 590

    Hi,

    I'v read some reviews on this GPU which say that it's quite power hungry, and actually it has an 8 + 6 pin slots for the power supply..
    Should I use 6+2 and 6 to power it up or 6+2 is enough?
    I don't intend to use this build for gaming generally, it might be tho very rarely.

    The video card may not start without both connectors plugged in.

    Yes, the video card is power hungry when you're gaming.

    The average maximum power consumption is 245w, with peaks up to 300w for a few milliseconds once in a while. It takes around 50-60w from the pci-e slot, and the rest of around 200w is taken from the extra power connectors.
    So let's say it takes 200w through the extra pci-e connectors when gaming. In theory, each connector is perfectly capable of even 300w or more through it (through the 3 pairs of wires, each pair capable of 100w+), but according to the standards, a pci-e 8pin allows for maximum 150w and a pci-e 6 pin allows for maximum 75w.
    So in theory, the video card would pull around 100w through each connector , or 150w through the pci-e 8pin and 25w through the pci-e 6pin connector.

    In Windows, when you're not gaming, browsing stuff etc, the power consumption is around 15-30w.

    For reference, RX 570 cards peak at around 175w and RX 580 cards peak at around 225w (one pci-e 8pin required)

    Most of the time I'll be on Linux, I didn't pay much attention to the card when I choose it for the build, mainly it was as a "backup", if I need to work with videos , or rarely gaming (on windows).
    Sometimes I don't boot windows for months...
    Hopefully on Linux it will basically be idle. Good to know that it won't boot if both pci-e aren't connected.

    I think that's not correct. The card can boot up with 2x 6pin connectors. Though it will shut itself down if you put gaming load on the card.
