Ok i apologize for being a true newbie here so I wasn't sure where to post this but here is the deal:

I have built my own computer, and over the last few months i have upgraded a few bits, new PSU, new GPU and a Liquid Cooler for the CPU.

However, I must have done something wrong in the process as my computer is really wonky lately.

I finally managed to get the CPU cooled down as it was overheating before, i also managed to upgrade the PSU from 450 to 750W but the air that is coming out of it tends to get hot really fast when i use the computer.

Also my graphics Card is getting hot easy so i Use Afterburner with the fan going manually at 50 while gaming and I feel my computer shouldn't be going hot this easy and i figure i either configured something wrong or i installed something wrong so here is what i got inside the comp right now:

AMD Athlon II X2 245
2x DDR3 Kingston 4096 MBytes
ASUSTeK M4A77TD PRO (Mainboard) (Bios 2301 - 08/11/2010)
Silverpower 750W
MSI HD 7850 1Gb
Microsoft Windows 7

(Please let me know if you need any more information about the inside.)

Do you see anything wrong with my powersupply from the speedfan picture? this picture was taken idle and the CPU and GPU never goes over 50 when gaming (GPU needs Afterburner to manually adjusted speed of the fan to not overheat)

Please let me know if there is something i should try out or if i have tried something because I dont remember half of what i tried at the moment, as mentioned i have been struggling with this for about 2 months.

Just to post something for you, here is the review for that PSU, take a look at the mediocre and see if that may affect you:

The Good
- Superb voltage Stability
- Above 80PLUS Silver level efficiency.
- Ripple? What Ripple.
- Lovely ribbon-style modular cables
- Capable of punching almost 200w above its weight.

The Mediocre
- Quite easy to plug molex/sata connectors into PCI-e sockets....eek

The Bad
- Ugly packaging and specs label on unit.

First off, thank you for the quick reply much appreciated. And I can see how this can be confusing and this is actually one of the things i struggled with. Not plugging it wrong but not being sure if i should use the PCI-E cable coming out of the PSU directly to my GPU or if i should use the PCI-E socket on the PSU and connect a cable from there onto my GPU.

I have tried both and they have given me the same output so I am not sure if it really matters, and i THINK that the reason for it being one cable already coming from the PSU and one optional output and a cable to use if you have multiple Graphic Cards, but i might be mistaken.

I am currently using the cable that is already connected to the PSU

Thank you too for the quick reply!

Yeah It seems like the GPU is the one hogging the power as everything else is just chugging along. So could this all be the quality of the PSU? or lack there of?

See this is my problem, i want to know if my GPU is doing what it is supposed to because I feel that if it had 750W it would be able to do all this without problems. But this is where I also doubt my own skills and may think that I have connected something wrong along the way. Is there a way of seeing if the GPU is giving the correct amount ? And is there a way to see if something isnt getting enough power?

i tried to add a picture from speedfan but i am not sure if it came with at all ill try again:

I just ran FurMark and it went flawless, image below:

Also tried MSI Kombustor, flawless:

any ideas what the problem might be? I am currently crashing while playing a game with the screen going black, buzzing sound and then a reboot.
