Hi Guys!

I'm building my first PC. I need help if my PSU would suffice to my components.

Motherboard : Asus ROG Strix Z370-G (Wifi AC)
Processor: Intel i5-8600k
RAM: G.Skill Trident Z RGB 3200mhz 2x8GB
GPU: Zotac Amp! Extreme 1080ti
SSD: 250GB 850 Evo
HDD: 2TB WD Green
CPU Cooler : Corsair H110i
LED : Deep Cool RGB 350
Fans: 3 140mm, 1 200mm

Power Supply
Seasonic S12II 620w 80 Bronze

I also wanted to OC my cpu and gpu, just in case needed.
I'm wondering if the 620w can handle it already?

Comments/suggestions are much appreciated!
Thanks in advance!

Regards,

Hi.I would suggest at least 800W PSU to be sure that you will have some spare power.If PSU is working almost at full load all the time it will reduce lifetime of it.Better have to take more powerful power supply so it could work at non-full output load.
Let’s see,what other people here aren’t thinking of this.

Then I need to resell this asap. Thanks for your advise!

When I run stress tests(CPU and both GPU are at 100%) Corsair link shows I have almost 700 Watts usage(689W).Maybe your PC will drain 450-500 Wats,depending on OC you will make,but having only about 50-80 Watts left is not so good.Remember that what is written in PSU doesn’t mean you have 100% of this power in output,only 90-94% of this.It depends on PSU quality.

Seeking assistance for my first build
