I recently purchased a new gfx card and psu. All was looking well during the fit, i thought i had everything connected properly but when i tried to power it on no luck. i did some testing (unpluging and repluging stuff mostly) and i found out that when the 4pin connector isnt connected to the motherboard my computer powers on. However i dont get any display on my monitor. I am desperate for help right now.

Also the 4-pin connector is actually 6-pin but it still slots into the 4pin socket near my cpu just fine.

EDIT : [MY PSU](http://www.corsair.com/builder-series-cx600.html)
EDIT: [motherboard](https://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&dlc=...)

I tried my old psu again with the onboard gpu to make sure i havnt fried my motherboard during the setup and everything seems to work fine. Please help i really have run out of ideas :S

Please make sure you are plugging the correct cables into the correct slots.
The 4 pin connector you are referring to is the ATX CPU power. No 6 pin connector should go in that slot, those are usually PCIe cables.
You should have a 4 or 4+4 pin cable that goes there. Again double check. Also if you could post a picture of your PSU cables that might help us to point you in the right direction.

Hope that helps.

I will try and take pictures with my phone and put them up as soon as i can. Will also double check everything is in order, i actually thought it looked odd having the pci-e in that socket.

Some, but not all, PSU's will label their cables. One of mine does, the other doesn't but if it does it should say cpu, pcie, etc. You def do not want a PCIe cable going into cpu slot, could cause damage.

Well its was running for about 20mins, i was downloading gfx drivers when a loud noise started coming from the psu fan. I restarted the system but the noise is still persistent. My computer works fine but the noise definitely doesnt sound healthy :S
