an 650w will suffice but the evga currently has a killer price

Price breakdown by merchant: http://pcpartpicker.com/p/tQtjGX/by_merchant/
Power Supply: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($89.99 @ NCIX US)
Total: $89.99
Prices include shipping, taxes, and discounts when available

another best unit would be this

Ok i'll tell you full specs

Processor - Intel Core i7 4770k

Motherboard - MSI A78M-E45 AMD A78 - Want to upgrade motherboard for a full size motherboard what's got 64 GB ram allowed and alot of fan ports

Graphics card - GTX 780

Ram - 8GB Crucial Ballistix Sport

Hard drive - 1TB Western Digital Black

Case - Corsair SPEC-01 - Should i upgrade to a full size case?

CPU Cooler/Fan - Corsair h100i - Would this be good for overclocking the 4770k?

Case fans - Corsair AF120 - I've added these to the h100i as they are very quiet - Should i upgrade? If i do i need quiet don't care about looks

What watt/power do you guys think i'll need and thanks for everyone's help!

Both are the same cards.
The newegg one is refurbished;
"Refurbished products may be unused customer returns that are essentially "new" items, or they may be defective products that were returned under warranty, and resold by the manufacturer after repairing the defects and ensuring proper function"
