urgent!!! HELP

[Nickolp1974]

trying to determine if my gfx has a problem, just tried my lads gfx in my machine and no probs, now i need to try mine in his, but his psu only has 1 6pin and i need 2 8pin, now without stripping my machine is there any way that i can just use my 8pins connected to gfx, and let his do the rest??????????

Yes, but you'd need your psu to be running. They start up via the 24 pin

thx for quick response, on mine can everything be left plugged in?

There might be, you could take the 24pin connector on yours and use a paper clip to short circuit two of the pins (google it can't remember which two, middle two normally). This it will start the PSU without having to be plugged into the motherboard) but I wouldn't recommend it, as I don't know what if the PSU will be able to regulate the power without being plugged into the motherboard.

Don't you have any 4 pin molex converters?

no i dont and i dont fancy plugging my card into a £30 450w psu!!!!


the power from the psu is it controlled at all via the mobo/cpu?

i have 1 6 to 8 pin converter on me

am i right in thinking that the gfx card bios determines what it draws from the psu?

totally disconnect your PSU from YOUR PC and only connect up the graphics card that is in his, you want to short the green wire on the 24 pin connector to any ground (black wire) also in the 24 pin connector, do this before you switch on his PC

the motherboard has no control over the PSU, the devices that are connected to it do, hence why you want to disconnect everything else from the PSU otherwise everything will be drawing power that doesn't need to

thx guys for your replys, well i gave it a go, got power there but no joy. now his pc wont boot, put his gpu back in mine its not that, what could i of done? would clearing cmos help?

 

[Nickolp1974]

after inspecting carefully my lightning installed in his pc, realised that it was not inserted fully due to the pcie catch on his asus p5qe. this is because there is a plate above the pcb which stops it going in all the way.

cleared cmos that did nothing, left pc on for 20 mins, all heatpipes on cooler and mobo are cool to touch, could i have blown his psu or broke his cpu/mobo doing what i did???
