Is this rig compatible?

[Matt430]

I'm quite new to the PC Building world, and I'd like to make sure that everything will work out before I order it. Here are my parts (It's a Gaming Build):

_______________________________

CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600

COOLER MASTER HAF 912

Seagate Barracuda ST31000524AS 1TB 7200 RPM

EVGA 02G-P3-1559-KR GeForce GTX 550 Ti (Fermi) 2GB

SONY Black SATA DVD-ROM Drive Model DDU1681S-0B - OEM

COOLER MASTER eXtreme Power Plus RS700-PCAAE3-US 700W ATX 12V v2.3 Active PFC Power Supply

Intel Core i3-2120 Sandy Bridge 3.3GHz LGA 1155 65W Dual-Core

ASUS P8Z77-M LGA 1155 Intel Z77

TP-LINK TL-WN350GD PCI Wireless Adapter

_______________________________

Also, an extra sort of question, does all the wiring needed come with the hardware and/or the case, or is their some extras that I need to order? If so, please list which ones. Lastly, (as an extra question), how do I get the power button working, the 2 USB ports, and the sound/audio found on the front of the case?

Thank you!

Compatible, yes. Something you should buy, definitely not.

Do you have a budget? I can give you some tips on how to make this better.

1) Dump the 550Ti. Its a pretty terrible gaming card. Its old, uses alot of power, and is not very fast for the price.

2) You do not need a Z77 motherboard for your processor. You can use a H67 motherboard.

3) That being said, I would go with a H77 motherboard and a second generation Intel i3.

4) Pick a power supply of a brand Antec, Corsair, or Seasonic. They are much more reliable than the CoolerMaster you chose.

Can you possibly give me a link for the graphics card you recommended and the power supply, please? Also, I plan on actually updating the processor in the future when I save up some money, if that makes it any more reasonable to keep in the setup. But for certain purposes, if it is possible that you can post some links on the components too, that'd be great.

They're all from newegg. You can get them cheaper elsewhere, but still.

Thanks for the answers! I'll probably still be looking around for graphics cards, though.
