I have no idea how to know if 400W is enough for my computer....

AMD A6-3650 APU W/ AMD Radeon 65XX HD GFX Quad Core Processor Socket FM1 2.6GHZ 4MB 100W Retail Box
G.SKILL Ripjaws X F3-12800CL9D-4GBXL 4GB 2X2GB DDR3-1600 CL9-9-9-24 Memory
Gigabyte A75M-D2H mATX AMD FM1 A75 2PCI-E16 1PCI-E1 1PCI DDR3 HDMI DVI SATA3 USB 3.0 Motherboard
Antec Fusion Remote (with IR receiver, LCD screen and remote)

ATI Radeon HD 3800
4GB DDR3
