Just need to be reassured that this will run my system at peak performance when gaming , i initially thought to get a higher wattage model but i thought this will be enough , Also i am going from an Alpine 750W power supply to this model i have linked below but i wanted to know if my new 550W Can handle my system for awhile without straining and blowing up on me if yes then how can it handle my system if it is 200W Lower than my old one and how much wattage roughly would i have spare , i have used this (eXtreme Power Supply Calculator Lite) but i am still not sure if it is accurate enough.

This is the new PSU i have bought :


AMD FX 4100 3.6GHZ Black Edition
Asus M5A78L/USB3
Kingston Hyper X Blu 2x4GB DDR3 1333MHZ RAM
Asus Nvidia Geforce GTX 550TI 1GB PCIe 2.0 X16
Seagate Barracuda 1TB 7200RPM SATA HDD
SATA Optical Drive DVD-RW-CD-RW Combo
TP Link Wireless Network Card 150MBPS PCIe x1
2x 120MM 2000RPM Blue LED FAN
OLD DC Fan Contoller Which says it uses 12V?

Yes no problem the XFX is built by seasonic and will handle your system no worries.For a system with a single GeForce GTX 550 Ti NVIDIA recommends a minimum of a 400 Watt or greater power supply with a minimum +12 Volt continuous current rating of 24 Amps or greater and with at least one 6-pin PCI Express supplementary power connector.

Yes it can handle a 650 ti with ease.As much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have an or several dedicated video card(s). As a general rule of thumb, you are aiming for the highest number on the 12V line.If you want to learn more about power supplies check these links out
