Hi i have just bought an msi gtx 670 oc edition. I have a powercool extreme power 450w PSU which is:

ATX 12V V2.2 Design guide compatible
has ATX 20+4P, 12V 4+P, 6P, 8P, SATA connectors

I have an amd fx-4100 3.6 ghz cpu

nope, it doesnt have enough wattage and PSU seems generic so it will probably fry at full load.

The minimum PSU for the GTX 670 is 500w with 30Amps across the rails, Unfortunately you have a cheap PSU and its actual Power output will be a lot less than stated if you want to run it continuous. Running cheap PSU's at full load just frys them fast. Agreed with above post as its an OC edition it may need that little extra power when running at full load so a 550w + PSU is what you need (try to get at least a bronze certified one if budget allows).

Depends on where you are.

The issue is that cheap PSUs tend to fry the rest of your computer when they blow.

Dont scrimp on a power supply trust me. Most computers I repair are due to someone overloading a crap PSU. Best case scenario is the PC will run for a time (not at its full GPU potential) then without warning you will get system crashes/freezing followed by the PC not booting (PSU dies in a good way). Worst case is you playing a game then POP it blows taking out your CPU or popping capacitors on your motherboard (usually the voltage regulators for your CPU).

Actually, yeah. That's a good one - the new CM ones are actually decent.

just to confirm (i don't want to get anything else wrong again) this will work with my m5a78lm-lx motherboard and rc 335u case right?
