Sure, it's generally fine if your motherboard's power draw is 5 watts over its maximum rating.

I swapped the Xeon E5-1620 for an E5-2690 and noticed the new CPU pushes your motherboard's power limit by five watts. With good cooling in place, this isn’t a major issue—it feels like a small overclock. Given how pricey these LGA2011 boards are, it’s worth checking stability first. If everything holds, adding a heatsink to the VRM might help keep things safe.
I used that setup for many years with an FX 8350, but it was noticeably more than 5 watts. You should be okay.
The CPUs have power limits of 130W and 135W. Your motherboard is designed for 130W only? That seems a bit insufficient for turbo performance. Could you share the exact motherboard model where the power rating is listed? If so, there might be a way around it by setting the power limit to 130W or less.
The team is currently using a Dell 8HPGT workstation board, which Dell states supports processors up to 130w. https://www.dell.com/support/article/us/...on?lang=en It’s a frustrating board that forced me to re-pin an ATX power supply to fit its unusual standard. On the positive side, it’s proven reliable for Blender and secondary gaming, and it performs very well. I also have an Asus model, but it has some socket damage, so I’m considering purchasing one of these cheaper options if needed: https://amzn.to/2REJoEE. Thanks everyone!
Dell adheres to the TDP as its long-term power cap. I'm uncertain about performance with an unsupported CPU. I'd like it to cap power usage at 130W, which would likely result in a minor drop in turbo clock under certain conditions but shouldn't be significant. It seems similar to what I've seen before—it's worth experimenting with. So far, I haven't used it much; I just used some extra ECC REG RAM that was available.
Dell's X58 boards were designed for 130 Watt CPUs, but they performed well above that without issues. An example shows a T3500 running all six cores at full speed with a TDP increase to 180 Watts—this difference is unlikely to cause problems. As long as the BIOS identifies your new CPU and loads properly, everything should work fine. If it fails to recognize the CPU, it won't display a message and will remain unresponsive in the BIOS screen.
