Question about upgrading my PC
Hi guys I was wondering if someone can give me advice on upgrading my PC. A couple years ago I got a Inspiron 3650 as a gift. I recently decided to upgrade it so I can play modern games on it. I had purchased a GTX 1050 ti (dual fan) for it. After inserting the GPU I noticed a six pin connector on the graphics card. I then noticed that the PSU that came with the computer is absolute ♥♥♥♥♥♥♥. It is a 240 watt PSU with only two cable that come out of it and they both connect to the motherboard, meaning that I don't have a six pin connector that can go to the GPU. If that wasn't enough, the PSU is a weird rectangle shape and the case for the PC is built specifically for that type of PSU. Meaning that If I bought a EVGA 500 watt PSU, it won't fit into the case. So my question is, does the GPU require me to add the six pin connector or is that optional? Another question is, will the 240 PSU be able to run the motherboard, CPU that came with the computer, and the GTX 1050 ti without any problems, or do I need to find a case that doesn't require that awkward PSU? And if you guys can find a stronger PSU that fits the case that would be great.

You need to change cases.

> That PSU won't handle an upgraded graphics card. Don't even risk trying - killing the PSU often damages other parts connected to it.

> Upgrading the PSU isn't an option. "powerbrick" PSUs like that are usually specific to one case.

> You can buy a much nicer looking case for peanuts, and that will accept any good PSU. It'll also keep your PC much cooler, thanks to extra fans.

So I checked my house and I actually have an old PC case that can fit a normal PCU. It is from a different manufacturer though. Would I be able to just remove the motherboard, hard-drive and other components into the new case? The Inspiron motherboard is a different shape than the motherboard that was in the old case.

It depends on what kind of board the Inspiron was built with. Assuming it's a standard ATX or M-ATX size(like literally any normal computer) it should work absolutely fine. I can only see it being a problem if Dell used a weird-shaped motherboard for some reason.

A vast majority of computer motherboards are standardised sizes, and use the same bolt-pattern to attach. As a result you can take a motherboard from any large enough case, and put it into any other case that's big enough.

It is large square shape like most motherboards, but there is a medium sized rectangle missing from the corner. Imagine a Square with a rectangular piece missing from the top right corner. That is the mother board that the Inspiron came with. While the old PC was built with a regular square motherboard. Also the architecture of the interior of the two cases are a bit different. The motherboard that comes with the Inspiron has wires attached to it that are for power and other functions. I'm worried that If i buy another case the wires wont fit properly or cant be placed in the correct location?

Here is the link to a Youtube video that has the exact PC that I have. Skip to about 1:00 to see the interior of the PC.

That's entirely possible.

I cut my teeth about ten years ago with a similar experience - my first build was a Dell Dimension I modified with a better GPU and more RAM. It eventually ran quite well, although the board and PSU were both nightmares to work with.

I guess the only thing left to do is try and move the motherboard into the old case. If it fits I'll buy a brand new case.

So I checked and there is absolutely no way that the Inspiron motherboard will fit. So I'm wondering, how important is the motherboard actually? I still have the old PC motherboard. Is it possible to just remover the Hard-Drive, CPU, RAM, and GPU from the inspiron and place it on the old PC motherboard, or am I just some idiot that doesn't understand how computers work?

Question about Cases and Motherboard?
I wanted to know if a motherboard will actually fit into a PC case. I know that the board itself will fit into the shape of the case, but what about all of the ports? The HDMI ports, Ethernet, etc. How do I know if the case port holes correspond and fit to the shape of the motherboard ports? I don't want to buy a case only to realize that the cases port holes don't align with the motherboards.

99% of the PC cases you see on the market are of universal standards so there is no chance of it going wrong, unless you've bought an ITX case for an ATX form factor board i.e. being too small to fit.

The ports on the mobo are covered by the I/O shield. A I/O shield will be included in the motherboard box.

No, It is not possible. You might as well buy a case, get an LGA 1151 motherboard, and throw everything on that. you will have to get new ram.

I'm going to be honest, Dell's are complete garbage basic systems.

You're better off selling the tower, watching youtube videos on how to build a system, save up money, and build a much better one.

I'll explain this in dumbed down terms.

Each CPU depending on generation and other factors can have different sockets, for example. my old I5 2500k had a socket of LGA 1150, while you're CPU's socket is LGA 1151,

LGA stands for land grid array.

Ryzen CPU's use what's called PGA or pin grid array, (difference is the pins are on the cpu not the motherboard).

Motherboards usually always fit, it's the rest of the stuff; especially the power supply and grahics card that can give certain cases trouble. All sites should give measurements, just do your homework before you buy and it shouldn't be a problem. If you get everything and it STILL doesn't fit there's no saying you can't DIY your case to MAKE it fit.

Port holes are on the IO shield, which comes with the motherboard.

To be absolutely honest with you, even if you could transfer a worthwhile number of parts to a new motherboard it wouldn't be smart or cost-effective. A better option would be to retain the GPU, and then build an inexpensive new system around a low-cost Intel Pentium or AMD Ryzen processor.

The problem is compatibility. A motherboard is basically a wafer full of connectors for different parts, unfortunately the ones in production today aren't compatible with either the CPU or RAM from your current machine. Intel CPU sockets aren't backwards compatible - a new Intel motherboard will only accept CPUs from within the current Skylake/Kabylake family.

With RAM it's a case of advancing technology. PCs a couple of years ago were built with DDR3 RAM, while modern ones use DDR4. DDR4 has a different mounting system and the two aren't cross-compatible.

I have it on good authority that this is a non-standard Dell motherboard.

Just read that part about the pins. Whoooo, this machine IS old! I remembering shaking like a leaf trying to get those pins to line up when I upgraded my 486dx and I still bent them a little. You should probably start over and give this one to Valhalla.
