Hello fellow partpickers, i'm building a build for a friend, ive got all the parts picked out, except for the psu, he doesnt want to spend to much however because of his budget (about 80$ for the psu) i am stuck between 2 the https://pcpartpicker.com/part/evga-power-supply-110b20750vr a nice B2 EVGA power supply, but only semi-modular, i would'nt mind modular, so i'm thinking of this one: https://pcpartpicker.com/part/evga-power-supply-220gs0550v1 im not sure if the GS are alright, but assuming it is, its only a 550w, i think my build requires 650w, i am planning on OCing his cpu to 4mhz, anyway i used this website to calculate, however i dont know if its a trusted website...

build: http://uk.pcpartpicker.com/p/p89GFT

website: http://powersupplycalculator.net/ it recomends a 500w psu at the most with Cpu at 4mhz and Vcore at full, (i honselty do not know what that is... i know what it is but i dont know how to calculate how much i will be using ...)

i am planning on OCin my cpu to 4mhz

... Well, your wattage should drop then... (current CPUs are measured in GHz, not MHz)

According to this site ( http://www.realhardtechx.com/index_archivos/Page362.htm ) you should have a min of ~850w for dual GTX 770's. As such, I would recommend getting a PSU from this list, depending on how much you'd be willing to go over budget... http://uk.pcpartpicker.com/parts/compare/evga-power-supply-110b20850v3%2Cxfx-power-supply-p1850bbefx%2Cxfx-power-supply-p1850xxxb9/
