What have i done?

[hardtofindinthefuture]

So i have a GTS450 that i wanted to test out, and use it with a 1x to 16x pcie adapter

 

So this is what i did

And when i power up the PSU-CO PSU the gpu fan starts to spin but when i powerup my PC the GPU fan goes at MAX SPEED and sounds like a get engine and the PC didn't boot (well i only waited for like a min but still)

 

Oh yea i also replaced the thermal paste on the GTS450

 

SO what did i potentially fuck up?

pci e pcb should never be connected to a external psu directly,  it gets 75watt powr from the pci-e lanes

 

using an external psu to power ur gpu isnt a bad idea, just dont friggen connect it to ur pcb lol , that (sata poweR) thing is where u fk up and probably kill the gpu, a 16x card wont work on a 1x slot, but the other way around it will btw

it can actuall dmg the pcie lane / card, seen it happen

Ok i have the GPU in now, connected directly in the PCIE x16 slot powered by the other PSU, there is no video, trying to download drivers for it now using intel HD

 

I don't think its dead because its being picked up as "unknown device, VGA compatible" in device manager.

Did you look at the diagram? He's using a 1x to 16x riser cable/PCIe adapter, which is how miners etc make multiple cards work in one system.

 

 

 

You did connect your monitor to the GTS450 and not your still to your PC when you're waiting for it to boot, right?

It's also not connected directly to the psu, as its connected to the riser, connected to his pc.

of course well yes and no

one cable is on Intel HD and another in the GTS450 (i have 2 monitors)

do not connect the riser's pcie power booster plug to a different psu than the pc is on.

I don't think you can use both at the same time.

HOLLLLLLLLLYYYYYYYYSHHHHHHHEEEEEEEET it worked for a second while installing graphics drivers, so i know for a FACT the GPU isn't dead!

ye but he connect a external psu to the pci-e lane , pci-e lane should be fed by main psu

thats exactly what i just said aha

 

same time

[hardtofindinthefuture]

well because of all this work, time to do some testing with the GTS450!

Thanks for the advice @Valkyrie Lenneth if not i woulda blown my GPU!

=P  just change the sata power thing to ur pci1 to 16x from ur main psu, instead of external  , having the pci-e power connectors from external psu is fine, but pci-e should remain from main psu ( 75watt anyway )
