Hello I have recently acquired a used pc from a friend and was wondering if it is possible to enable sli on it

it has 2 gpus
A gtx 1650-super
And a gtx 1650

it has a i5-2500

and an hp 1494 mainboard

I'd like to use sli so I can run games on a 5 monitor surround type setup.

No it does not work. SLI was an technology, but was never able to drive more displays than one single of the two GPUs could drive. Only performance was better. but it had lots of problems, so avoid that.
You also didn't have twice VRAM, but the same data in each card.
GTX 1650 is quite weak. I would suggest you to get something like this for 5+ displays:

ASRock Radeon RX 5700 XT Taichi X 8G OC+

A stronger card with 5+ Display out in parallel - I must search a bit, there might be one.

On Nvidia you are "limited" to "only" 4 displays, except for pro cards.

Not quite - asus 4090 and 3090 cards has 5x display outputs.

I had a 3090 with even six outputs, but you can use only 4 at one time. It is design limitation by Nvidia.

Are you saying that 4 displays limit is PER GPU or PER SYSTEM? I would hope that limitation would only be PER GPU because if you had multiple GPUs then I wouldn't understand why you couldn't use 5+ display simultaneously

and when I say that I should clarify I mean just basic display driving. I'm not talking about gaming with a 5 screen wraparound IMAX like experience. so what I'm getting at is the OP could drive 5+ display with those two GPUs....right? But they wouldn't be able to get to their goal of using 5 displays for an extended display setup for gaming

Per GPU as stated in Nvidia specs. Using SLI does not work, as one will be the master with all outputs and the slave(s) just for rendering.
But if you plug in more GPUs and use them in parallel (no SLI) that could work.

The OP should just connect the 5 displays on both cards and report back. The 1650 doesn't even support SLI, but it wouldn't help at all since SLI would limit to 4 displays then.

The gpus are in parallel but when I try to run games across all 5 screens it's extremely laggy but when I only use the screens hooked up to 1 card it runs smoothly

I will look into upgrading to a single, more powerful gpu.
