which psu wattage do I need?

[ʙᴜɴ.ᴇ]

Hi, building a pc.

Intel Core i9 9900k
Asus Rog Maximus X Hero Z370
Nividia Geforce 2080 ti
32gb 2666Mhz Ram
Corsair Hydro H100i GTX
500gb ssd
4tb sata

What power supply unit do i need to power this safely? I want some leeway in what power is used to power my peripheral's which include a lot of music equipment.

thanks!

I would get a quality 750w PSU.

[_I_]

for a single cpu and single gpu, a quality 600w is more than enough
80+ bronze or better by a reputable mfg

the diablotek 1050w would have problems with most systems

I suggest doing your own research, just to make sure. Do you intend overclocking? Maybe not w/2666 ram.

I'd buy a 1000W. But an 800W tier 1 at least.

The 9900k can use 250W itself.
The 2080ti w/bios tweaks up to 360W if you can keep it cool. W/o tweaks 260W.

That's 510 - 610 W for just those two components.if the wattage figures are correct. Realistically it should be a lot less.

Add in water cooling, mobo,etc.

On tomshardware some people are saying 1200W, 1600W for sli.

edit - I didn't add anything for music equipment.

I am inclined to agree with Omega on this one. 750Watts is enough. It leaves room for a future motherboard, CPU and RAM upgrade. Get a fully modular unit if possible. and a case that mounts the PSU on the bottom so you can maximize cable management.

+1 750w
EVGA is a good way to go

[Missing Spartan]

750W should be all you need but if you do intend to overclock you might want to look into an 850W maybe.

Then I advise you stop garnering your technical information from tomshardware

The 2080 ti is a very power hungry GPU, and same story with the i9. This machine will easily pull 500w-550w from the wall.

This is my spec, and use a Corsair RM850x PSU, no issues what so ever..

CPU: Intel Core i9 9900K @ 5.1GHz
CPU Cooling: NZXT Kraken X62, AIO Hydro with RGB Lighting
GPU: MSI GeForce RTX 2080 Ti Gaming X Trio
Memory: 32GB G.Skill Trident Z RGB DDR4 @ 3500MHz
Mobo: ASUS ROG Maximus XI Code Z390
SSD: 256GB Samsung 950 Pro M.2 PCI-e 3.0 x 4 NVMe
SSD: 1TB Samsung 860 Evo
SSD: 500GB Samsung 840 Evo
HDD: 4TB WD Red
PSU: Corsair RM850x Full Modular 80 Plus Gold
Case: NZXT Phantom 630 White Edition Full Tower
RGB NZXT Hue+ with 4 LED Strips

Cooling:
4 x Corsair 120mm Blue RGB Static Pressure in push/pull config on the Kraken X62.
3 x Corsair 120mm Blue RGB Air Flow front intake.
1 x Corsair 140mm Blue RGB Air Flow rear exhaust.

The 2080Ti actually uses less power than you might think, a lot less power in fact than my long in the tooth 980 Ti when gaming / under load, about 70w less.

I just ran a power supply calculator tool that is provided by #1 IT research company. (I'd can't tell you who because I'm a dentist.) The estimated power draw was 700W.

I ran an overclocked config through the coolermaster power estimator. The result was 682W. Without overclocking the 2080ti, the result was 585W.

Coolermaster recommends running a psu at 90% load (but I wouldn't).

I recommend you to buy a watzmeter and measure power consumption in your own. You talking huge BS you have read somewhere but never measured yourself. Early provable.

A Z370 Motherboard only has 8 Pin EPS which can deliver in theory up to 235W. There is no way that the 9900K pulls 250W itself simply because the motherboard can't deliver it in the first place. Beside that, even an i9-9980XE has a TDP of 165W and fors not actually consume that much.

The GPU and pull 360W even tho remotely in theory possible. You would have to modify the card to actually do that. I know you read it on tomshardware but the reason that they can measure spikes of that is the energy saved in capacitors what does not measure the actual wattage pulled from the PSU.

No RTX 2080 Ti I measured would come with the worst efficiency calculation over 250W power consumption.

In the end those are theory measurements with high end overclocking boards - with his motherboard he won't even be able to reach 500W power consuption. 650 or better yet 750W for the efficiency is way more to be on the save side without overspending on a PSU he can't make use of

Here's a video of an i9 pulling 250W:

I have a digital link psu, no need for a watzmeter, even if I could find someone to sell me one.

Gamers Nexus is where the 2080ti power info came from and supported by Reddit, not Tomshardware.

https://www.reddit.com/r/nvidia/comments/9jsh9n/2080_ti_ftw3_has_the_highest_power_limit_by_far/

The psu power recommendation came from Cooler Master.
http://www.coolermaster.com/power-supply-calculator/

You should send them all an email and tell them they all talking BS.

[Washell]

It's well known that all psu calcs provided by psu sellers are bs and will grossly overestimate consumption. We wouldn't be telling coolermaster anything new. If they were to reply honestly, it'd be "We know. It's on purpose in order to sell our more expensive, high margin units. "

As for the reddit thread, from a quick read, those are theoretical maximums supported by the board and bios. Not actual attainable and useful consumption figures. As in, you need to overclock and overvolt it to near death to get that. The gpu, as people mention in that thread, will stop running reliably long before that. As such, it's not a useful number to base a psu purchase on.
