Hi, Thanks for taking the time to search for info. I have found the source of the problem by disconnecting power to various components until the PC powered up. It was the Blu-ray writer. So I swapped the data cable for a brand new one out of the box and a different power cable and it booted up. I did connect both the four pins to the motherboard even though all are curved squares on the left four pins but did connect without having to force it. I did read on a forum with someone with the same problem and they was advised that the curved squares fit into just a square hole no problem. I was following the instructions in the motherboard book but they didn't specify this Thanks again

Yeah sure, Its :- [h=1]Asus M5A99X PRO R2.0 AMD 990X (Socket AM3+) DDR3 ATX Motherboard[/h]EVGA Supernova 750W Fully Modular 80+ Gold Power Supply Im also using :- RAM HyperX 4GB 1866MHz DDR3 Non-ECC CL9 DIMM XMP HyperX Savage x 2 CPU [h=1]AMD Piledriver FX-8 Eight Core 8350 Black Edition 4.00GHz (Socket AM3+) Processor[/h] GPU [h=1]Asus GeForce GTX 750Ti OC 2048MB GDDR5 PCI-Express Graphics Card[/h] and the case [h=1]Corsair Carbide 500R Midi Tower Case[/h] Regards

Connecting power to CPU Now im having problems with connecting the CPU to the PSU. My motherboard has an 8 pin connection that looks like this :- Where the 'C' is the slightly curved hole and the 'S' is for the Square hole C S S C S C C S However the cable that is plit into two looks like this :- With the left cable matching the left part of above :- C S S C Bu the right part just being all curves C C C C So wouldn't match up. I tried just connecting the left part only but when I press the power button a light apears and goes off straight away and doesn't power up. So do I need to buy a different cable or could I possibly have a faulty PSU? Thanks again

Such a shame, the PSU is in the way so doesn't quite fit even though there are holes designed specifically for 120mm and 140mm fans. Looks like ile have to keep it to the top as exhaust after all

Yeah, seems a bad idea to have one of the top ones intake. I was thinking a better idea would be to keep the two front fans and large side fan as intakes, the rear as exhaust, one of the top fans (one at back of case) as exhaust but move the othe top one to the bottom of the case blowing up. That way shouldn't interfere with the CPU FAN. Does this sound like a good idea? Thanks again

Currently building a new PC and would like some advice on best fan configuration. I have the Corsair Carbide 500R, which has two 120mm Front Intakes, One 200m side Intake and a 120m Rear Exhaust Fan. http://s5.postimg.org/dba33tqh3/20150823_193412_HDR.jpg http://s5.postimg.org/5xup4v6fb/20150823_193443_HDR.jpg I have also purchased two 140mm Corsair SP140 fans that I have installed at the top of the fan, set to exhaust. http://s5.postimg.org/69c5hmmvb/20150823_193422_HDR.jpg However im thinking it may be better to have one of the top fans as intake, leaving the one nearest the back at exhaust but the other one as intake. I have a large air cooler that has an intake fan installed onto it. So im thinking may be better to have the air from the top just to the right and above it as intake, which will suck the air in and then directly to the cooler. http://s5.postimg.org/wrusqcll3/20150823_193401_HDR.jpg Or will that be odd and best to leave it as it is? Thanks in advance James
