You firstly need to check if the CPU is compatible for the motherboard you have chosen.
some motherboards are specialy made for intel or amd and can vary in the processors the can handle.
soncondly you need to check if the RAM you are thinking of using will fit into the slots on the motherboard and if the the motherboard can handle this ammount of memory.
thirdly ( is that even a word???) the graphics card. oh joy.
All motherboards have a PCI express port on them unless you buy them for £5.
"Power Supply & Case Cooling - 700W Quiet Quad Rail PSU + 120mm Case Fan"
this power supply might have a 20 or a 24 pin connector.
this is nothing to worry about unless you buy a motherboard with only take 20 pin. most of the new motherboards can take a 24 pin connector but the PSU that you are thinking might have a 2 pin connector. this is nothing to worry about because most motherboards with take 20 or 24 pin connectors. the PSU should be perfect for the power output you will be getting. make sure that the PSU that you get has a special connector for SATA hard drives because it may only have IDE power cables in this case you will need to buy some. they are not expensive. hopefully you do know but also when you will buy the CPU, you should also get a CPU Fan as well, be sure to use the thermal glue type thing to help conduct theheat from the CPU to the cooler.
try and use all of the power sockets for the motherboard that the psu provides to optimize performance. on my desktop, it has the initial 24 pin main power connector and it also has a 4 pin second input from the psu to the motherboard.
If you ask me the system should work together no problem.
email me when you do this and tell me how you got on.
