Solved Will this power supply be sufficient?

Specs: Windows Phone 8.1
I am in the process of building a new budget based PC (for both gaming and general usage and some video editing here and there) I have every part picked out, however I am indecisive over whether or not the PSU I picked out will run this system without issues, so looking for either a yay or nay in the PSU I decided on (haven't bought anything yet) or suggestions, need to keep the PSU at or around $50, my original choice was a Corsair 430 watt semi modular, what I will be running hard wise is:

AMD FX 6300 95w
GeForce GTX 960 2GB
2x8GB DDR3
2x80mm fan
2x120mm fan

Plus obvious keyboard/mouse, USB headset, etc

I know there are PSU calculators out there, and that is great, most state around 380 watts needed, however that leaves me with just at or just shy of ~50 watts extra, no plans on overclock in the near future or upgrades in 6 mos to a year, and if I do decide to upgrade at that point I'd have no issue.with a psu change as well. Any recommendations?

I don't put a lot of faith in wattage calculators. The 2 biggest power consumers are the CPU & graphics. You already have the CPU listed as 95W; the graphics is 120W. The majority of that power is pulled from the +12v rail, so figure about 18A for the two.

The Corsair 430W is a solid choice & it's on sale for just $20:

But if you wanna play it safe & have plenty of reserve for future upgrades, go with this Corsair 600W for just $37 after rebate, but you'll have to act fast:

BTW, you don't need all those fans. Choose a case with the PSU mounted at the top, put one 120mm exhaust fan in the rear & be done with it. Front intakes aren't necessary & side panel fans should be avoided.

All good advice by riider, above. I was of the top PSU school until my last build. Top mount cases are getting harder to find. I picked up a nice bottom mount at the local Micro Center. Bottom mount is OK as long as you have a large fan (120/135mm) in the rear at the top. No side fans.

I agree. Bottom mounted power supplies are fine as long as you have a good strong exhaust fan rear near the top. If you have a crowded case with a bunch of hard drives then a front intake fan may help. Tops fans are only needed if HWMonitor shows higher temps than you like. side fans should always be avoided. The difference between a cheap 120mm fan and a good 140mm ball bearing high CFM low Db fan is maybe $6. to $12. so getting that one really good fan is always worth the difference and will save you in the long run (you probably won't need a second fan, won't need to replace it possibly ever, and probably save valuable components).

You have to be a little bit crazy to keep you from going insane.

Alright thanks for the advice, yeah I was more just worried that it wouldn't be sufficient for what I am running (as I said, basically if I decide to do an upgrade at a later point then I will upgrade the PSU as well, right now it's more budget oriented so as long as everything runs smoothly I'm good for now), thanks for the info on the cooling as well, I figured I most likely would not require that many fans, just out of curiosity whats the reasoning behind not having the side mounted fans?

Side fans just disrupt the front to rear flow of air.
