I just bought a PowerColor 7850 2GB GPU from ebay.com
This model : http://www.powercolor.com/global/products_features.asp?id=449#Specification
for $70, (upgrade from my MSI 6450)

And my psu is a MX-F1 350w psu and it has "6P PCI-E"

Now when i was putting my build together on pcpartpicker it says
"1 additional PCI-Express 6-pin power connector is needed." but on the PowerColor website it says it only needs one?

(I bought the computer already build amd fx-6300,msi 6450,350w,4 gb g skill ddr3 1600 blah blah for $270. I know the gpu is the most important to upgrade first and a 7850 was the perfect for my 350w psu.)

this website shows 289 watts system load, sometimes your gpu may need a spike of power and it wont have it, if you want to add more things or plug in fancy peripherals it will be brinking on 350 watts, i would upgrade your PSU, and you have no chance of overclocking it.

it is also a tier 4 PSU which is pretty unreliable. its not even 80+ certified, you should upgrade it. http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html


can i have a link to your pcpartpicker build?

+1 to replace that PSU, being a tier 4 unit it must reach around 60-65% efficiency at its best, if you're lucky the GPU will run but when on load it will throttle itself due to lack of enough power giving you a low performance, get a better quality unit, at the very least tier 3 550w+.

yes, you will save on power bill alone. you also dont risk frying your components due to a bad power supply.
