I'm working on building a franken-rig of sorts using these parts http://pcpartpicker.com/p/38nwm

plus the parts I have from an older computer:
8 gb of ddr3 ram
280w Power Supply

pcpartpicker suggests 230 watts, but I assume that would be a little off. Would my current PSU work? (I don't plan on overclocking)

do you have the specs on the 12v rail of that particular psu. this is the part you need to worry about. it should be on the psu its self or if you could list a make/model that would help

Is there any reason that you chose last years model of CPU? Do you already have an LGA 1155 socket motherboard and that is why you chose it?

Im aiming for a cheaper build, this is moving from a dell optiplex 745 desktop with an AMD Radeon HD 6570 tossed in.

The website doesn't list anything specific about the power supply. (Ill take a picture of the sticker on it)

nvidias site recommends a 400w psu, however if you are already running a 6570 they both have the same tdp, 60w. but since you are upgrading mobo and processor i would upgrade the psu as well the 12v rail on the oem psu most likely will not handle the extra power draw

it says your 12v rail pushes 16a max
this is 192 watts max
3570k is 77w
chipset/mem is no more than 84w
650 is 60w

this is 221w on 12 rail you will need a new psu

this is a reliable tier 1 psu with more than enough power for your needs and future upgrades for 50
