Is this power supply going to be good enough for my upgrades?

I'm about to convert my budget PC into a gaming PC and I have some concerns about the power supply. This was originally a low wattage setup, so I went with the EVGA 400W100-n1-0400-l1. Basically the cheapest "name brand" I could find since I had minimal requirements.
Now that I am doing the upgrades, I'll be using over twice the power.
It is only now that I researched this power supply to find that it is apparently rebranded junk, on top of only being 400w. I thought I could trust the EVGA brand, but I guess not...
I'm wondering if I should just bite the bullet and replace it...

I used one of those calculators to figure out the wattage with my new system, and it says I will be using 275W total with my CPU at 100%, my new 1060 6gb video card, and three case fans. It recommends at least a 313W power supply on the same website.
My concern is the "junk" factor of this power supply and the fact that I'll be running 275W on a 400W unit, that has 75% or less efficiency....Am I worrying too much, or should I get another power supply?

I'd pick up a Seasonic 520W PSU https://www.newegg.com/Product/Product.aspx?Item=N82E16817151094

https://www.amazon.com/Corsair-Bronze-Certified-Non-Modular-CP-9020121-NA/dp/B01MRW2K79 is another option.

Toss in eventual OC'ing, which has gotten much simpler over the years and a new PSU looks even better.

If you are looking to the higher end I recommend https://www.newegg.com/Product/Product.aspx?Item=N82E16817438094. With a 7 year warranty behind the PSU it'll be there for at least a couple of builds with a safety net.

EVGA...and some just not good.

So do you think this "not good" 400W one is too risky to be using with the 275W max power consumption?

I'm assuming that's what you two are alluding to, since you are both suggesting replacements. I just want to make sure before I throw out a working PSU that I haven't yet had issues with lol

I understand I'll eventually want more power and will for sure need it if I do anymore upgrading at all, but I am wondering if I would be taking too much of a risk by holding off on upgrading the PSU? I guess I'm just not sure how much of a buffer builders normally give themselves...

Att his point I'm looking at replacing the PSU after less than six months of ownership, so IF I do need to replace, I would definitely be thinking of not just this upgrade, but how much power I would need on the NEXT upgrade.
The question is, is 650 overkill? Let's say I end up with an i7 and a high end graphics card years down the line...Could I run that with the 520W for 35 dollars, or would I want something like this 650W?

I'd be happy with the 520. Ummmm, so will the PC:D The fully modular PSU will look nicer in the build. You'll only be using the cables you need. But at twice the price I am not really seeing an upside that justifies the G3's price. $35 for a clean slate and you have one for troubleshooting? Works.

Nice. I am fairly certain the warranty is transferable. Sell it or keep it for troubleshooting.
