Jul 8, 2019 21 0 15 How much wattage does the Noctua NH-U12A take? Solution

ReHaq said: GPU: -GeForce RTX 2080 Dual EVO CPU: -AMD Ryzen 7 2700 Storage: -Intel 660p 512GB M.2 SSD Case: -NZXT H500 Black Ram: -Ballistix Sport LT DDR4 16GB Power Supply: -Corsair TX550M, 550W PSU Motherboard: -ASUS ROG STRIX B450-E GAMING, Socket-AM4 Click to expand...

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.

Are you asking what its power draw is or what it can handle for TDP? Upvote 0 Downvote

Jul 3, 2016 1,192 129 19,740 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.

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? Upvote 0 Downvote R

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. Upvote -1 Downvote

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. Upvote 0 Downvote
