Will this psu be alright?

[WahabA]

Not so long ago, I made a topic asking about PSU wattage. I figured that I might need 850-watt PSU or something like it. I realized I might upgrade some things, later on, so I thought I'd go with 1000 watt.

I have just found a

"Corsair RM1000i Power Supply - 1000 Watt - 135 mm - 80 Plus Gold certified" for 160 dollars.

 

But is 80 plus gold certified alright to keep a desktop going for years? I have watched both JayzTwoCents & Linus video on power supplies, yet I still feel kinda uneducated on the topic.

And if this power supply is alright, and will function properly. Can someone help me understand how to choose a proper PSU anyway?

 

I have a list of the parts i might use down here, not sure if that would help.. 

CPU: Intel I7 9700K

GPU: 2x 2080 in SLI (Zotac amp extreme)

Motherboard: Z390-F

Ram: 4x8 GB G.Skill TridentZ RGB Ram (Going to upgrade to 32 GB, in the near future)

Memory: Samsung Evo 860, 250 GB + Seagate Barracuda, 2TB 3,5'

Cooler: Nzxt Kraken X72 (I'm planning to replace the 3 fans, with 3 RGB fans from Corsair)

Fans: 4x RGB fans from Corsair

 

Besides that, I have monitors, keyboard and basic stuff like that.

80plus Gold only denotes efficiency, not quality. 

 

However, the RM1000i is an amazing PSU, and should be fine for your build for a long time.

Yes

the rmi and rmx series are great, but you really don't need that much. this build would be about 600-700 watts, so 850 would be more than enough

Well, how do I know? I've tried to figure out how much the individual parts need in power, but I just don't get:

1) What do platinum, bronze, and gold even mean for PSU's

2) How do I know how much the individual part of my pc might need?

3) What is the difference between all these different series of PSU's?

The 80+ certification is for efficiency. Nothing else. It meets certain efficiency targets at unrealistically low ambient temperatures. And bait and switch isn't that uncommon for manufacturers. It says nothing about how good the PSU is.

You don't need to care about the individual parts. For the system power consumption, you can look at reviews. For a rough rule of thumb, take the GPU TDP and add 70-100W. That should give you the power draw under a gaming load.

Between the RMx and RMi? The RMi has a FDB fan instead of a rifle bearing one, it has support for Corsair Link, and it has multi rail.

I am kind of understanding some of the terms now. Thanks for the help, I just wanted to make sure that I didn't buy something really bad, I've always had great experiences with Corsair. But assuming I'm using a lot of money for this, just had to make sure it was alright quality. I'll buy it now, thanks for the help!!
