Is a 550w power supply enough?

Good day!

This is my second time posting in this forum and I am still a newbie regarding PCs.

 

It has been a month since my father and I bought this PC (we haven't bought a GPU yet due to the crazy prices right now). Everything is fine until I thought about the power supply we bought, which is a Corsair TX550. I'm currently worried because the PSU we bought may not be enough once we're able to buy a GPU. I've tried power supply calculators like Cooler Master, BeQuiet and Outervision, but I can't still figure out whether this PSU is already enough because other people say that some PSU calculators are exaggerated. I really want to be sure if this PSU is enough so that I can decide whether to save for a new one or not. :( 

Here are the specs of my PC:


Processor: Intel Core i7 8700
Motherboard: ASRock Z370 Extreme4

RAM: G.Skill Ripjaws V 16GB 2400MHz (2 sets of 2x4GB)

CPU Cooler: Cooler Master MasterLiquid Lite 120 (1 fan)

Case Fans: Raidmax R120TP (I have 3 of them, I might add another one soon) 

HDD: Seagate 1TB (7.2K RPM)
SSD:  Adata SU800 256GB (I will buy this along with the extra fan soon)

Optical Drive: Asus 24x Internal DVD-RW 

GPU: Asus ROG Strix GTX 1080 Ti OC (This is our target GPU but we don't have it yet)

I don't have other accessories like RGB strips or what. I don't and I won't overclock anything too.

I usually use my PC for 14-16 hours per day.


Thank you.

it's fine. It will reach 90% of capacity at most (with heavy OC), still safe for long periods of use.

The TX550M is fine.

 

Also, buy the SSD now and HDD later, not the other way around.

Got it. Thank you!!

So, does this mean I don't have to buy a 650w or a 750w PSU?

Yes lol, if the power supply is any good it usually means it's rated for 24/7 operation at it's full rating as long as it does not surpass it's temperature limit.
