building new pc, don't know the psu wattage I need.

Hi all.

I have no idea how to find out how much wattage I need. One calculator I tried said @normal 444w, and another said 644w.
My build is by budget, mostly thinking about the gpu.
In my country this costs about $1.420
I don't think I will oc my hardware, because I've never done it before.
At most little gpu tweak when it's getting old, but I doubt it.
I will go for stock cpu cooling to begin with at least. (always been with stock, it works)

Case : CoolerMaster Elite K350
Gpu : MSI R9-280X-GAMING 3G
Cpu : AMD Piledriver X6 FX-6300 3.5GHz Black
Ram : 8GB Crucial Ballistix Sport 2x4GB 1600Mhz
or : Corsair 1600MHz 8GB (2x4GB) Vengeance
Mobo: Asus M5A99X EVO 990FX
or : ASRock 990FX Extreme3
Hdd : WD1002 FAEX, SATA3, 6 Gb/s, 64MB buffer, 7200rpm

  1. Best answer
    You will need about a 600w psu.
    Here is a chart that will give you a good recommendation for a psu.
    Whatever you do, pick only a quality unit like Seasonic, antec, xfx

  2. Yea your motherboard supports up to 220 watt cpu. In case u need it. (Future proofing) guess 250 watts to be safe.
    The graphics card needs up to 600 watts. So I would do an 850 /900watt psu or more. It's always better to have more than to have not enough.
