Following @LukeSavenije it's not worth it, there's much better units out there

 

Have you already ordered any of these parts? There's quite a few changes I'd make

You can still get a 9700k if you'd like, but I don't think it's worth the extra tax.

ok thanks for the suggestions, ill probably make some of those changes

Buys overpriced shitty board and tries to save up on PSU...

 

There's no issue with an i7 9700K build specially if your main goal is just gaming since the 3700X falls behind on that aspect but do a better research on the z390 chipset as a whole.

 

Alternatively you could go with Slottr's suggestion but replace the board for the cheaper Prime-P (has the same vrm as the TUF) and a ryzen 5 3600 as it has the same gaming potential of the 3700X and then shift this money you saved into the 2080 Super for better gaming performance.

[RainingTacco]

If you are buying new PSU why would you opt for an old design PSU like this seasonic? Also never skimp on PSU, the 20-30 dollar difference is 2% of the price of your PC,that's nothing.

that sums it up, even leaving some other things out of the way

 

the problem with m12ii evo (based off the famous s12ii), but group regulated units in general is that it isn't made for modern systems, because they didn't have those in mind at the time

 

as the 12v gets hit well with this kind of system, while the 5v stays rather low, the 5v rises to an out-of-spec level as they're regulated together (hence the "group" reg name)

 

with that the s12ii has no UVP on the 12v rail, making it easier to drop down until either OPP or SCP detects it.

 

something like that rmx would work quite well, but i saw a similar psu for 10 bucks less: bitfenix whisper

 

both from cwt, just a different platform, as corsair did a custom on it

Btw, a silicon power A80 or team MP34 costs $5 less but is much faster.

Yeah, I was just lazy and left the SSD they already had in there haha

Well, to answer your question regarding the PSU, I would suggest you to aim for 750W 80 Plus Gold PSU. RTX2070 Super do consume a good deal of power. You can still use 550W PSU just fine, though if you plan to add more cooling (fan, radiators, pump), it may overload the PSU.

https://www.anandtech.com/show/14586/geforce-rtx-2070-super-rtx-2060-super-review/15 314w with a 9900k and 2070 super with furmark. 550w is more than enough.

Yeah, but what if you want to OC? And when you are OCing, you need a good cooler, and that means adding fans and maybe a pump for liquid cooling. I'm not sure about you, but I still use many traditional HDD to store my archives, so that adds a bit (25W per HDD). Like I said, it 'may overload the PSU', though not necessary. When you factor these additional things, you may find 550W PSU is just enough for your system.

 

By the way, having a higher PSU means he can upgrade his system without ever worrying about PSU in the future. Let's say he wants to upgrade to RTX2080 Ti in the next couple of months. He might need to upgrade his PSU too if his PSU could not churn the power for all the components.

 

Also, Higher Wattage PSU generate less heat because their load is low. If you compare 450W PSU and 750W PSU, and your max load is 400W, you'll notice 450W PSU gets warmer than 750W PSU because the 450W PSU load is higher (about 80%) whereas 750W PSU is only at about half load and it can stays cooler.

[MrBrightSyde]

I changed a couple things to the list Slottr made for you. Changed the PSU to the slightly cheaper 650w BitFenix Whisper M that's actually a A+ tier PSU compared to the A tier RMx (not much of a difference in real-world but it's more watts and cheaper while still being 80+ Gold and Fully-Modular) and changed the SSD to the EX920 which is a NVMe m.2 compared to the SATA m.2 drive on your list.

 

Also, you can buy everything off of Amazon (GPU is $30 more though, unless you go back to the Gigabyte Windforce) when they re-stock on the 15th if you want all your parts to arrive at the same time (who likes waiting for the one vital part of their build?)

a good 550w is enough for a 9900k + 2080ti system, overclocked. 

 

so i dont see why you would ever need more. GPUs simply wont exceed the 300w mark as you reach meme territory. same regarding consumer CPUs. 

 

HDDs, and SSDs together with fans use minor rails. together with the fact you wont reach a burning 550w on the 12v means you have overhead.

Closer to 5W per drive. Wattage calculators are bullshit.

I guess for average gamers, they don't need much. I got mine graphic card hogging 320W when I render a 4k video (using Vega 64 by the way). With the LTO tape drives and 4 SAS HDD running at full speed (RAID 10), also using USB-C to power my monitor, 6 PC fans to cool off the PC (I don't have an air-cond room, day time temperature could exceed 36c average), and also to running SQL Database. I can easily hit 550W with my setup.

I think they take the worse case scenario. Older HDD do consume quite a lot of power. I remember one HDD I saw rated max power of 50W. It's 7200rpm high performance HDD 80GB using IDE. HDD since then getting more and more power efficient, and almost all laptop HDD can run on 5V only (Though you need a boost converter to up convert for 12V).

 

Desktop HDD still use slightly higher Wattage than SSD and laptop HDD, though.

You would peak at 550w, which is still fine......

Yeah, and burn it in the process due to excessive heat (The PSU has a fan and functioning, but it's quite warm). Thank goodness my components are intact.

In any case, I still would suggest a 750W PSU, just to be on a safe side.

What on earth are you on about?

 

A PSU doesnt die when peaking at its rated continious wattage. In fact, most do about 20% more before OCP kicks in to protect the PSU and components

 

750w is way excessive for any consumersystem. 650w is really overkill aswell.

PSUs are rated for continuous power. Do you know what "continuous" means?

It means it can only do it once, right?

Nah, it means it can continue to do so, but each time it peaks, suprise mechanics kick in and it may kill your system
