What I'm tring to do.
Measure the current being pulled by my 9800gtx's (two of them) but only the current bing pulled down the pci-e connectors.
Why? the Enermax Pro82+ 525w psu I'm using for my build only has two 6+2pin and one 6pin pci-e connectors and I need 4 pci-e 6 pin.
I'm currently feeding the last pci-e connector with a molex to pci-e adaptor, however due the the cable layout of the Pro82+ this has made neat cableing a real pain.
I'm pritty sure that this psu can feed four 6pin pci-e, seeing as 8pin pci-e are rated for twice the wattage of the 6pin version.
So I'm currently considering modding the cables.
However before I start hacking a working PSU I want to check the actual working amperage.
A clamp meter should be just what I need to check the current flowing along the wires, however I've never used one before and my multimeter skills are very rusty.
Would something cheap like this work? http://www.maplin.co.uk/Module.aspx?ModuleNo=222032
What do I need to look for to measure 12v DC amperage?
