Does my motherboard support 105w TDP CPUs?

[BS8619]

Hi. I have an Omen 30L and just upgraded the CPU to a Ryzen 9 5900xt. It says it has a TDP of 105w. But my power consumption is 65w. Am i limited by my motherboard or my PSU or what?? Thanks

Welcome to the HP Forum.

Maybe I am misunderstanding but it sounds like you did a successful 5900X upgrade.

You would have to provide a specific product number to possibly check MB specs. HP Support sites have been spotty lately. It may be difficult to check your PC's MB specs.

You're good to go if you did a successful 5900X upgrade and the PC is doing fine.

TDP is calculated by CPU manufacturers and CPU cooling manufacturers using their own metrics. The formula used to calculate TDP varies by manufacturer. Noctua uses a different way to calculate CPU power requirements for their CPU air coolers.

The PSU can cause instability if it can't provide enough watts to the CPU and the graphics card.

Inadequate VRMs located around the CPU socket can cause instability.

Any MB manufacturer can use BIOS limits to lock upgrades to specific TDP CPUs.

Thank you for the quick reply! Its an Omen 30L Desktop GT13-1xxx. 

edit: Just realized its a hana 8876

The cpu works but its performance is horrible without full power

My pleasure.

The Hana MB supports the 5900X.

Did you upgrade the HP included CPU cooler when doing the 5900X? HP matches components based upon the CPU config. at purchase.

So the MB VRMs are capable of providing enough power to the CPU socket.

The BIOS would have limited options, so doing PBO in the BIOS is probably not an option.

You could try Ryzen Master to tweak CPU and memory performance.

Gt13-1xxx is a generic PC ID. What PSU do you have?

Did you upgrade the graphics card?

Maybe the HP stock PSU can't handle the load if you also did a GPU upgrade.

But you would generally see an unstable PC if the power supply is inadequate.
