Hi there,

I have recently upgraded my graphic card and I wonder if I still can use my old graphic card power combined with the new one. Here are the specs:

New Graphic card: ASUS GeForce RTX 2080 O8G ROG STRIX OC Edition GDDR6 HDMI DP 1.4 Type-C graphics card (ROG-STRIX-RTX2080-O8G-GAMING)

Old Graphic card : ASUS GeForce GTX 980 STRIX-GTX980-DC2OC-4GD5 4GB 256-Bit GDDR5 PCI Express 3.0 HDCP Ready SLI Support Video Card

Motherboard: ASUS X99-DELUXE LGA 2011-v3 Intel X99 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

Power supply: CORSAIR HX Series HX750 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active

If it's possible, do I need to to buy a more powerful power supply?

Thank you

You can install two cards; and your psu will handle both/
But... why would you want to?
The old card can not be combined in sli to boost performance.
And attaching a second monitor to the RTX2080 will not hurt gaming performance in the least.
