llo! I have recently attempted a computer build with components I was recommended during a previous thread I had made back in december (which is linked at the bottom of this thread). I finish my build using all of these parts and turn it on, and you could guess that to my surprise it did not work. All fans were rotating and it sounded fine until it wouldn't display on the monitor. Then, after at least 30 seconds of it not displaying it shut itself down. I continue to do this three times and the same result happens every time. Then I notice that the GPU's plug did not have the correct connector to power it plugged in.

I was using an old PSU for my new build, which would previously used in my old computer, which is a Stealth Xstream 2 PSU 700W, and I was reccomended to use this in my new build.

The rest of the parts I used: http://uk.pcpartpicker.com/p/2lPEJ

The thread I opened: http://www.tomshardware.co.uk/answers/id-1934259/buildi...

Another thread I opened: http://www.tomshardware.co.uk/answers/id-1993695/operat...

I am unsure what to do now considering the computer does not work without someone else's advice on helping my getting it working. If you feel it was the power supply that I need replacing could you recommend me one by using the information I have given in the previous thread + the parts I was previously recommended. I am kinda in a bit of a muddle so to speak.

Thanks for reading this thread. - Matthew

So what you are saying is, you are not getting display and the PSU doesn't have 6 pin PCI-E connector/s for GPU right ?

Now are you planning to buy Be Quite 600W PSU or already owned it ? If you already owned it then I am sorry to say its not a good PSU.

Remove the GPU from system, plug the monitor to on-board VGA/DVI port, see if you can get the display !

We will continue from there on.

So, are both connectors (6 pin and 8 pin) plugged in the video card currently? It is not clear from the text.

At the moment I do not have the be quite PSU 600W as I have the Stealth Xstream 2 PSU 700W, which I am using from my older computer. I will have to attempt to do what you said at later date but will do it soon and will get back to you if it works.

Another question though is about the wattage In that is 700W of power too much for the system I am building? I am afraid of damage to the machine. If so, could you recommend me a PSU to buy which will work with my GPU? At this moment, the PSU (Stealth Xstream 2 PSU 700W) only has a 6 pin connector to plug into the two slots for the GPU. I need a 8 pin and 6 pin connector for this GPU from the PSU.

Your PSu is really OK.
Stronger PSU will not damage your system. The computer will draw for it as much as it needs.
Please check carefully the cable connectors of the PSU, accordin all sites I've seen (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) there should be 1 x 6-Pin, 1 x 6+2-Pin, these 6+2 must be joined to form 8 pin that should go in the 8pin card slot.
6+2 pin PCIe should look like this: http://www.pcper.com/images/reviews/690/15-PCI-E.jpg

First of all don't buy that 600W PSU, get this one if you need: solid as a rock :

PCPartPicker part list / Price breakdown by merchant / Benchmarks

Power Supply: XFX 650W 80+ Bronze Certified Semi-Modular ATX Power Supply (£70.86 @ Aria PC)
Total: £70.86
(Prices include shipping, taxes, and discounts when available.)

Secondly you can use any bigger PSU (1500W) it wont damage your system, it will take as much as needed by the components, no more than that no less than that, so don't worry about higher wattage PSU's.

GTX 770 is a 230W card on max load and requires 1 x 6 pin and 1 x 8 pin connectors. A 650W PSU will be enough for your entire build cause the system will never use more than 450W max.
