My computer runs slower with new graphics card

videogamerpc · Oct 26, 2017

So I installed a new graphics card on my pre built Dell inpiron 3847 and it seems like it downloads updates and video games slower. It's not a gaming PC but I checked out YouTube and people have upgraded the model to play games. Corsair has a video as well. Here's what I did.
Installed a Zotac Nvidia GTX 1050 ti 4gb into a
i5 4th gen
3.20 GHz
Intel Radeon graphics driver
8129 mb ram ( I think originally it's 1tb)
300 watt power supply
It is a pre built off the shelf computer. I called Dell and they said I couldn't install a graphics card because it could damage it but YouTube says otherwise that's why I did it. I did not buy a new power supply since the gpu has a minimum requirement of 300 watts. Did not buy more ram. I did not uninstall the Intel(R) Radeon hd graphics driver either, I didn't see an option and supposedly I didn't need to.
So here's what I gathered might be the problem.
1: I didn't uninstall the Intel Radeon
2: I do need a better power supply?
3: maybe install a ram?
4: Dell is right and I should take it out and build or buy a gaming computer.
NOTE: I did play a video game after I installed it (PUBG) and it ran it just fine with no lags or problems. I did do research and decided to do it.
This is a pre built not meant for gaming just a home computer.
I hope tech savvy people will give me some advice or answers but either way I'm not mad i just wanted try something new and now I know more about building a PC.
Thank you.

> 2: I do need a better power supply?

depends on the graphics card. 300 sounds low. depends on what else is in the system. the right way to do it is to add up the watts of every component (the MAX wats not average) and then figure you need to be above that. some gaming cards put allota load on a ps, and dell likely put in only the ps needed to do the job right for the configuration as sold.

however the card you mentioned doesn't need "and extra plug from ps", it gets it's power through the pcie slot

as far as speed goes ...

why not run run the software that came with the card that shows all the voltage power consumption fan speed AND video refresh rate? also the intel tool for the i5's stats as well. that may supply some insight (and help you see if your watt calculation is right)

btw never "take advice" off youtube. consider it an "idea" and research if the idea works with your own thinking (ie, do your homework when creating a system: which includes pin level compatibility and mobo configuration, power consumption, drivers, and sometimes atx case fitment of parts being able to fit in the case)

post some results you see that might give a hint to others what might be going on

for all i know your driver upgrade "didn't go right" and it's just a win10 driver issue

I would recommend upgrading the PSU to a good 450W unit like a Corsair CX450M.

The OEM Dell PSU's are normally pretty weak, especially the lower wattage units.
