[Gadget] Zalman ZM-VPM1: VGA Power Consumption Meter

Zalman ZM-VPM1: VGA Power Consumption Meter

I just discovered this cool gadget: the Zalman’s ZM-VPM1. The ZM-VPM1 is a VGA power consumption meter (wattmeter in short 😉 ) for your graphics card. The ZM-VPM1 comes with a gender converter you plug between the graphics card and the PSU that allows the ZM-VPM1 to measure the voltage and current intensity in order to get the power consumption.

Zalman ZM-VPM1: Gender converter

According to the docs, the gender converter seems to support only 6+2pin. So either two gender converters are required for cards with two 6-pin or 6-pin + 8-pin power connectors or two ZM-VPM1, one for each power connector…

And what about the power consumption at the PCI Express slot level?

    yeah seems the design team didnt put too much thought into this product. 6+2pin isnt enough..aswell as the pci-e power

    would probably be cheaper to hook up a digital multimeter..and calculate it manually!

    I’ve read that the PCIe slot delivers 75W of power, so just add that value to the value displayed by the gadget.

    I will buy a power meter for 1Gb DDR-5 ZOTAC GeForce GTS450
    but it has a capacity of 258 watts (max) and the device has a range of 10 ~ 240Wt
    will operate GeForce GTS450?
    thanks for the help 🙂
