Hi guys,

kinda need your inputs here

i'm currently building my new gaming system with R3 2200G, Sapphire RX 580 Nitro+ (factory overclocked at 1411 Mhz core clock)
, 2x4GB 2665MHz RAM, SSD, HDD

i'm still hesitant on the PSU part, Sapphire recommends a 500w PSU, but i have one experience when i was trying the same GPU to my old setup (pentium gold 5400, 2x4GB 2133mhz ram, and Silverstone Strider Essential 500w 80+ white)

there was one occassion where my PC reboot itself during game (it was the division). and i think it was my PSU incapable of handling the RX 580 because all was fine when im using RX 570 the past few months.

so should i go for PSU above 500w?

i'm planning on Seasonic S12-II 520w or Antec Neo Eco Classic 550w Bronze

does 550w will gives more headroom compares to 520w?

because i saw some RX 580 cards even have PSU recommendation at 600w (e.g. Powercolor Red Devil 8gb)

Sapphire official pages says the power rate of Nitro+ cards is at >235watts, does it means it will not go beyond 235watts in power consumption by any case?
 
A good 550w should be enough but the fact is the 580 can spike to 280w for miniscule periods of time.

This can be detrimental on lower end psu's.

The antec is the better choice of those two, although in all honesty its still close to only being just enough power wise.

So do you think 600w is the safezone for RX 580?



How about Seasonic M12 or Antech neo ECO II variant, i think they are newer version of each PSU i mentioned earlier?

Also waht do you guys think about these options?

Enermax LEPA 650w Modular N650-MA
XFT XT series 600w
Enermax Max Pro 80+ 600w
Thermaltake RGB Smart 600w 80+ white
