New PC need help on Power supply......

Hello all, I have Dual core 2 E6400, 3 gig of pc-5300 ram, 160gig WesternDigital harddrive, asus quietrack cd-rom combo, P5N-E SLI mobo, CPU cooler Fatal1ty FS-C77, 5 80mm fans with LED, 8800 gts 320mb xfx OC'ed, Sound blaster Platinum Fatal1y X-fi sound card... I dont think is a pain in the butt how big of a power supply would i need to run all this and leave room for a 30% safe guard?? I have my eyes on a hiper-R 580w Powersupply would i be able to run this and leave room for other add's??? Thanks..

That corsair is an amazing unit, but this is a better deal. Another top quality unit (PCP&C) with 49A on the 12V rails for the same price!

Thank you for comments and thoughts i will upgrade with a bigger PS with more Amps toward the rail, and yes hiper is a known company here in europe and not much in the states since the company is based in England, i am american but living here in russia and its very difficult here too find a decent PS for the price im telling you... In the USA ive done my PC shopping on neweggs and loved it but here its very hard.... Thanks again for the info...
