Do I need to upgrade my power supply unit to upgrade my graphics card?

OMEN by HP Desktop PC - 880-109no
Microsoft Windows 10 (64-bit)

I'm owning a OMEN by HP Desktop PC - 880-109no which have a GeForce GTX 1080  Ti graphics card installed as default. I'm considering upgrading that card to the latest card from Nvidia, the NVIDIA GeForce RTX 3090. My question is, can I do that without replacing any further hardware such as the power supply, and if I need to do that, which power supply would you recommend?


I hear that GeForce cards can be run in parallell as well, would it be possible to run my old card parallell with the new one?

The existing card uses 180W and requires machine with 500W PSU minimum




 And the RTX 3090 card uses 350W and requires machine with PSU 750W minimum




Your machine has 500W PSU, you need 750W PSU or at least 500W + 170W PSU(170W = 350W - 180W)


Hope the following link helps you to select s right PSU
