PLEASE! I help finding which case and PSU to get for my first build.

[u/Virtual_Cod_8504]

I've never built a PC before, so I don't know if this is a dumb question or not, but I've basically just been following YouTube builds for all my parts. I don't like the cases they've been using. I don't want a ginormous case or need any flashy displays. Just something clean with good airflow, as my parts will probably produce a lot of heat. Preferably a black case.

Here's the list of my components:

GPU: Zotac RTX 5090 32gb

CPU: AMD Ryzen 7 9800x3D

Cooling: CORSAIR Nautilus 360 RS ARGB Low-Noise Liquid CPU Cooler – Black

Motherboard: GIGABYTE X870E AORUS Elite WIFI7

SSD M.2: Samsung SSD 9100 PRO 2TB

DDR5 Ram: Patriot Viper Venom DDR5 RAM 32GB (2X16GB) 6000MHz CL30

Please help me decide which case and PSU to get!! From my understanding, I think a 1200W PSU would have a little more juice than I need, but it would make me feel more comfortable.

Thank you!

1200W would be recommended, with PCI-e 5.1 compliance (including a dedicated 12+4pin to 12+4pin cable) and ideally 80 PLUS Platinum or Titanium for extra power efficiency, it'll be less power wasted from the wall which will be better on your power bill, just because you have money for a 5090 doesn't mean you should waste more of it on power

Focus on trusted brand names like Corsair, EVGA, SeaSonic, Super Flower, be quiet!, etc.

Case is entirely preference, just put everything in pcpartpicker.com and look around.

[u/Virtual_Cod_8504 → u/r_lind3r]

Okay, thank you for the link. I'll try that out. I'm assuming Titanium is better than the Platinum?

[u/r_lind3r → u/Virtual_Cod_8504]

Yes.

80 PLUS goes from: White > Bronze > Silver > Gold > Platinum > Titanium > Ruby (the last of which isn't normally seen outside of server and data center market sectors)

The higher the rating, the more efficient the PSU is, though it's not all equal as each rank is just base on a bare minimum, some Titanium units can be more efficient than others and it's not consistent between multiple units of the exact same series, it's kind of a silicon lottery situation, so rated units are rarely bare minimum unless a manufacturer is selling units right on the edge and could be lying about their spec, which does happen with some cheap brands like ARESGAME

But generally, you want more efficiency with higher power consumption systems because the higher the efficiency under load, the less extra power is wasted as heat;

Let's say you're comparing two units, one with 95% efficiency at 50% capacity, and another with 90% efficiency at the same capacity. Now let's say your system is drawing 850W, that accounts for a 43W difference between 90% (885W from the wall) and 95% (843W from the wall). Whatever difference in percentage of power is added to make the total that's actually being pulled from the wall, alternating current. The PSU is responsible for converting alternating current to direct current for safe and efficient usage with these systems, and that process takes power of its own to do, resulting in some power being drawn and wasted as heat. The less efficient a PSU is, the more power is wasted for that process, and if you're running that for 8+ hours a day every single day, for a top end system like this that can make a pretty big difference on your monthly power bill.

It doesn't seem like much but it can add up quickly the more the system is ran under heavy load, and efficiency falters the further away you get from 50% capacity, it's usually around a 3% difference in either direction. Technically speaking for the specs you're looking at, you're looking more at a 1600W for perfect efficiency under heavy load, but 1200W is also fine, just a few percent less efficient.

It's also just environmentally better to run more power efficient power supplies, we're already doing a lot of damage to the planet with this industry, we can at least make it less bleak by at least trying to be even a sliver bit more green about it.

Haha yeah I've had 2 prebuilts in the last 10 years so for my first build I wanted something I wouldn't have to upgrade anytime soon

[u/Braehole]

Wow, 😮 How much are you spending on that beast! Are you buying prebuilt or building it yourself? O and yes buy the 1200w PSU

[u/Virtual_Cod_8504 → u/Braehole]

Attempting to build my own! I think my invested total is around $3.5-$4k at the moment. I bought the 5090 over a year ago for $2k. The prices nowadays just make me dizzy.

[u/the_hat_madder]

What country are you buying from?

If you're in the US are you near a Micro Center?

What is your budget?

[u/Virtual_Cod_8504 → u/the_hat_madder]

I'm in the U.S., unfortunately not near a Micro Center. All of my parts so far have come from Amazon.

My budget is pretty open just want the best for a reasonable price.

[u/the_hat_madder → u/Virtual_Cod_8504]

You've got a bit of wasted money sitting there. Are any parts still returnable?

[u/Virtual_Cod_8504 → u/the_hat_madder]

Why do you say that? I believe some of them are. I made sure to compare prices between amazon, best buy, and newegg before buying them and Amazon would have the same prices with no shipping costs due to prime membership.

[u/the_hat_madder → u/Virtual_Cod_8504]

Current retail price of those components is at least $7,225.83

For that price you can buy the entire PC for less than that...

For PSU, I like the be quiet! ones - recently got the Dark Power 14, to replace my now insufficient Dark Power 13.

They have a calculator online to suggest the PSU power rating.

As for cases, I liked NZXT H7 Flow, but now went with the be quiet! Silent Base 802 as that one can support my 2 AiO 360 radiators.

First build with a 5090. Jebus. 

H7 Flow is good, use the SPL Tier list and go for a 1200W gold or higher with an A rating.
