    But you know the wattage being used, by looking at the rating plate of the device you have plugged into the socket. So a 2kW electric fire will be drawing 2,000 watts, or using 2kWh per hour.
    Electricity is metered in kWh, not in watts.

    this is for checking the consumption of various PC builds before specifying the correct 12v PSU

    I do not need to know the cost , just wattage BEING used not in Kwh but shown as Watts being consumed
    I have access to at leased 6 online sites that are supposed to "calculate" the total used by inputting the parts , but they vary a LOT


    the types of wattage I will be testing are between 60w and 300w , all via a single 13a plug

    It's the case not for all devices, including a PC that the OP mentioned. For a PC the power varies depending on the regime and settings. PSUs are rated by the max power they can produce and efficiency .
    Electricity is metered in kWh, not in watts.
    You measure the power or the consumed energy, not 'electricity'. The power is measured in Watts (W).
    Devices are called 'Energy Meter' (incorrectly) or 'Power Meter'.

    The power shown on the meter wont be that accurate in choosing a power supply.

    The CPU and graphics cards power consumption will be more of an issue.

    Graphics card may tale 60watts and yet require a minimum of 300watts, but that increases with the CPU and additional drives.

    Some cards require a certain power on the 12v rail also. Some have
    a large 40+ amps on the 12v rail and others have 2 x 20 Amp rails.

    Fit a decent PSU.

    Those meters are horribly inaccurate with certain types of load.
    You plug it in and it shows nothing, your thinking "there is NO way that device uses almost zero power!!"

    thank you , however there are a couple of things I need to mention before walking off and shooting myself


    the PCs I am referring to are the type that have Micro ITX boards , now in an average build they use motherboards that have incorporated video cards.


    the other point to mention is that they use PICO motherboard headers , a clue to their usage might have been in my comments "60 to 300w"


    I need to get a figure of the wattage used , before ordering the correct size of Pico adaptor and 12v PSU


    this is a pico adaptor and a corresponding PSU

    Sorry if I'm teaching you to suck eggs but don't forget that its peak watts that count.
