[SOLVED] What is the best psu for this lenovo pre-built pc

[Legendary1]

Here's the model number : 90LX0002IN
i want to change psu so i can add the better gpu

 

[Legendary1]

Case seems to be small and i don't have knowledge on pc building, i just want to upgrade the psu to the better one

 

[Lutfij]

You can't! Why? Because the motherbaord in your prebuilt has a proprietary connector, even if the PSU is in a TFX form factor. The person in this video:

was right to upgrade the ram and storage but the GPU will only result in the system blowing up. That system wasn't meant for higher powered components(since it's work environment is for light work at home or at the office).

Gt 1030 won't work on this power supply? i heard it needs only around 30watt
There's no way i can change the psu?

You will need a low profile graphics card that will run on pcie slot power only.
You should be OK with a GT1030 using the existing psu.

IF any GPU which doesn't require extra power than the PCIe slot works, then the best GPU to get would undoubtedly be a GTX1650

existing psu is around 180watt. just wanted to do causal gaming
so it is fine with Gt1030?

In theory, yes.
But the case has little ventilation and a GT1030 is a big jump in capability over integrated graphics.
I don't think I would test the assertion with only a 180w psu.
The i3-9100 processor has a TDP of 65w.
A pcie slot maxes at 75w leaving precious little left over if a max 75w gtx1650 Is installed.
I think a GT1030 would be a fine upgrade.

Oh thanks for replying and help

Do i have to remove DVD to save watts for rest of the system? will it have some issues such as low watts for main components?

Other parts than the cpu and gpu use minimal power.
No need to disable anything.
I might suggest that if you do not have a ssd for windows that you upgrade.
It will make everything you do so much quicker. And, yes a ssd will use a tad less power than a hdd and will generate less heat.
If you use a samsung ssd, the conversion is very simple using their ssd migration app.

I wouldn't worry about ventilation as my Zotac GTX1650 barely reaches 65C (unless CPU overheats) but the power consumption may be a problem.

Anyway, I was wondering if casing of a prebuilt could be raplaced. Is it possible?

 

[Legendary1]

You mean to replace the case? then yea, it is possible

 

[Ziadul87]

I'm not sure if that 180W PSU will provide all of that on the +12V rail. So I guess, if possible, you should change the casing, get a 400-500W PSU and then a GTX1650/RX570.
Even if you run GTX1030, I'm not sure if there won't be random shut downs under load. (My 192W pre built PSU shuts itself down after 2-5 mins of load even with GTX 1650).
btw, how much are you willing to spend on the upgrade?

I can attest to replacing the casing. I was on a HP Pavilion Power pre-built that had way too powerful components for what the case is apparently designed for (i7-8700, GTX 1060 6GB). It was a baking oven.

Got tired of it, bought a Z390 Aorus Pro motherboard, a new PC case with a mesh front for airflow (be quiet! Pure Base 500DX) with some ACTUAL case fans, a new CPU cooler and proceeded to move every single part from the pre-built apart from the mobo into the new PC. It was a fantastic decision. New casing alone dropped temps by about 15C.

Of course, now I'm moving to a B550 Aorus Pro board, Ryzen 9 and Noctua NH-D15. At this point, the only thing carried over from the prebuilt still in my rig would be the Sandisk X400 SSD.

I would NEVER have been able to make these upgrades on that prebuilt, which is why you should look into either getting a new casing for your current components BUT ditching the mobo for a non-OEM one, or saving up for a new system entirely.

 

[Ziadul87]

With 4 GB of RAM, you won't be able to play many of the new titles. So, a good GPU might not be so useful without a RAM upgrade. But then comes the question whether your mobo allows additional RAM slots. You are probably looking at a costly overall upgrade 🙁. Your choice is more limited to what your budget allows now

Replacing the case would fix the psu problem?
200$ - 250$

Ram isn't problem at this moment. i have opened my pc and it have one ram slot there and inserted a 4gb ram

i just want to remove this crappy psu from my life or new causal gpu which can run at least all games in low settings or medium

Then , get a PSU for around 50$, a GTX 1650/RX570 for 150$ and spend the rest on casing.

New psu will support this motherboard?

You can't! Why? Because the motherbaord in your prebuilt has a proprietary connector, even if the PSU is in a TFX form factor. The person in this video:

[Ziadul87]

if you can't get a new PSU, then no point in getting a casing or a GPU. You could try the GTX 1030 (No guarantees). Not much to do if power supply is limited 🙁
as i said, if you're looking to upgrade, you're looking at a costly upgrade.
btw, getting prebuilds is a bad idea. best to build yourself a PC
