How much wattage does the Noctua NH-U12A take?

How much wattage does the Noctua NH-U12A take?

Are you asking what its power draw is or what it can handle for TDP?

Hello , ReHaq , I found this information for you.

https://noctua.at/en/products/cpu-cooler-retail/nh-u12a/specification

Make sure you read the top line , socket compatibility , I have the NH-D15S , that is slightly bigger , just look at the measurements of these fans they are huge so make sure it will fit in your case.

I have the coolermaster half x tower and the company who built it refunded the cost of 2 top of case fans as they said their was not enough room which seems strange because upon receiving the rig their looks to be more than enough room.

3.36w max.

Im not sure if i have a big enough power supply, and i wonder how big the jump of power use is from the stock amd ryzen 7 2700 cooler to the Noctua NH-U12A

Your power supply is so bad, that you're concerned about CPU COOLER FANS?!

I think there's some misunderstanding going on here...

Your cpu, and especially the gpu, have a far greater impact on psu load than some mere fans.

Post your PC's specs and the make and model of your power supply, please?

The power draw from that CPU cooler will have no effect. In essence you are trading out 1 fan, from your current cooler, for 2 fans. Each fan will draw like 4W of power and will not make any difference. With a 550W PSU you have the minimum wattage needed for your build to have some overhead. You will be just fine.

How much headroom do you think i exactly have?

How much headroom do you think i exactly have?

Ryzen 2700: Around 140w at stock - closer to 210w if overclocked: https://www.techpowerup.com/review/amd-ryzen-7-2700/17.html

RTX 2080 Dual EVO: Find out the max power limit of your gpu. Download and run Gpu-Z: https://www.techpowerup.com/gpuz/
Click on the Advanced tab, then the drop-down box, and on Nvidia Bios. Note the max power limit from there.
I couldn't find the bios for your exact gpu, but I'll be using the power limit from the following gpu for my example: Asus RTX 2080 Dual OC - Non Evo (270w)

25% of headroom for everything else in the system...

140 + 270 = 410. 410 +(410 x 25%) = 512.5w
210 + 270 = 480. 480 +(480 x 25%) = 600w

Between 512.5 - 600w. But those are worst case scenario numbers. You're not going to draw that much normally - those numbers are from stress tests.

Those numbers that techpowerup has is Whole System Power with a 1080Ti. During their gaming loop with Witcher 3 the 2700 is at 351W. This not a case where you are adding 140W + 270W + X = system power as Techpowerup already has the full draw calculated with their benchmarks.

Well, crap... I totally missed that.
Down vote my answer, would you? I really slipped up there.

No worries, I don't know how many times I have misread something. Happens to everyone.
