Is SeaSonic S12II 520 Bronze enough for this build? (i5-6600k/R9 380x)

Hello, I'm building a pc that has an i5-6600k and an XFX R9 380x in it, this is the full build:

CPU: Intel Core i5-6600K 3.5GHz Quad-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO
Motherboard: Gigabyte GA-Z170-HD3 ATX LGA1151
Memory: G.Skill Ripjaws V Series 8GB (2 x 4GB) DDR4-2400
Video Card: XFX Radeon R9 380X 4GB DD XXX OC
Case: NZXT S340 (Black) ATX Mid Tower Case

I plan on overclocking. Do you think the SeaSonic S12II 520 Bronze PSU would be good enough? or should I go for more (550-650)?
Thank you!

  1. Best answer
    it would be fine without overclocking but since youre overclocking get the 620w version.
    better safe than sorry :)
  2. I would advise against it. Although the seasonic psus usually could safely operate higher than their tag, there have been a decent amount of psu related problems with the 380x. So yes go for the 620, the price difference shouldn't really worth it.
  3. I am pretty sure you would be fine. I am running a 6700k and a 970 OC'd to high hell on the S12 620W EVO and come nowhere close to 400W tdp. If you can stretch its nice but if it means skimping on other parts it is not worth it.

    its not good for a powersupply to run at a 100%/ youve got a quality powersupply.
  5. Thank you guys for your answers, I will get the 620W to be safe.

    The 970 is a much more efficient card when it comes wattage demands. The 3xx line generally is quite consuming.
