PSU Wattage choice.

[RiffoSai]

Hello. I made a pc configuration but i dont know what PSU should i get. Thats what i am thinking of buying: CPU: Intel Core i5-4690K GPU: POWER C AXR9 290 4GBD5-PPDHE Motherboard: Gigabyte Z97X-SLI Intel LGA1150 Z97 RAM: HyperX 8 GB 1600 MHz CL9 DDR3 HyperX Beast(2 x 4GB Case: COOLER MASTER Storm Enforcer CPU Cooler: Cooler Master Hyper 212 

One optical drive and one HDD. In the Case there are 2 fans Front: 200mm Red LED fan x1, 1000 RPM, 19 dBA

Rear: 120mm black fan x1, 1200 RPM, 17 dBA

 

I am really messed up because the video card requirement says 750W. But at diffrent sites for calculating says like 500W.

Video card requirement by companies can be ignored. They over-exaggerate things by a mile. For this a quality 500-550W PSU is enough

XFX 550W is a really solid choice, good quality, seasonic board inside + 5 year warranty from xfx

600W should leave room fro expansion

i woad personaly good wight a 600w fore that gpu  when overclocked(Amd had in mind that you do)said that psu requrment you can go 500W but i wundt recomend it bicuse of cpu (if overclocked it can pull 200W notime and gpu overclocked can go around 300W mark prety easly i waod go wight 600w minimun 1200w max and i woad go wight geforce gtx 970 from nvidia since it has arond 2 fps more in most games has same memory buffer  and leser tdp and power reqaraments fore itself.If you need open CL preformance go amd if you need something like premire or adobe i woad go nvidia.
