Even for ocing cause the psu calculator said 489 watts

The calculator is wrong as all PSU calculators are...

There's very little room in that card for OCing and without it it gets to 350W of entire system power consumption http://www.hardocp.com/article/2015/09/21/xfx_r9_390_double_dissipation_8gb_video_card_review/10

 

Thought I'd throw in a 390X (so the higher-end card that uses more power) and an overclocked 5960X reaching 342W under load https://www.guru3d.com/articles_pages/msi_radeon_r9_390x_gaming_8g_oc_review,8.html

So i can take the 550W aswell with no problems cause it will run pretty heavily with my setup

There's no issues to worry about. There's literally 0% chance that your system is using more power than a 5960X and a 390X.

TDP != power consumption.

ah ok thank you. Cause so many sites say 360 watts

Btw the XFX one has one 6 and one 8 pin so 275W tdp. My sapphire one has 375

What...?

 

As I said, TDP is not equal to power consumption.

Yeah i understand but my sapphire 390 can potentially draw more power pecause two 8 pins

No, that means it has a higher power threshold. There are GTX 960s with dual 6-pins and yet they use less power than GTX 970s that have single 8-pins. The pin layout only loosely correlates to how much power the card draws.
