A couple of questions about my Build

[Scoutdrago3]

Hello everyone! Heres my build:

-Rosewill BLACKHAWK Gaming ATX Mid Tower Computer Case, come with Five Fans, window side panel, top HDD dock

-MSI R7850 Twin Frozr 2GD5/OC Radeon HD 7850 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card

-ASRock H77M LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard

-Crucial Ballistix Sport 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model BLS8G3D1609DS1S00

-Intel Core i5-3450 Ivy Bridge 3.1GHz (3.5GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 2500 BX80637I53450

-Seagate Barracuda STBD2000101 2TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Retail kit

Is this build all right? Will I have any problem with the compatibility of any of these parts? Also if something might be better for compatibility then please tell me. Also what is the best PSU for this build? Most people say you shouldn't just get the max wattage needed but you should choose carefully. Thank you

Also will I need a CPU cooler or will the 5 fans that comes with the case be fine?

Sorry for so many questions, this is my first PC build, as you can probably tell by now

EDIT: Ok I found out that the 3550P is not compatible with the H77 so I changed it to the i5 IvyBridge 3450.

EDIT: That website was perfect, I have no incompatibilities, but will I need some type of cooler, I already have 5 fans. Also what is a good PSU, the total voltage was 294W

Also can you direct me to a normal ATX? I have the i5 3470 'Ivy Bridge' 1155 socket processor. I currently have the H77M(Micro).
Thanks
