I want to upgrade the processor of a desktop. The desktop is Inspiron 580s by Dell. The motherboard is named in the PC as "Dell inc a00".
I also have the serial number of the motherboard, but I don't know if I'm supposed to keep that information private or not.


How can I check which processor is compatible for my motherboard?

It turns out I was wrong, my motherboard's name is Dell 0c2kjt.

After some research I found out some compatible processors. I picked Intel core i5 760. However, that processor requires 95 wattage which is 22 more Watts than the current processor. Also, the new processor does not have integrated graphics card, so I need to add one graphics card. I managed to find one that consumes little watts, only 19. This means that changing the processor and adding the video card will increase wattage by 41. The Power Supply Unit is rated at 250 Watts max.
I will also need to change my CPU fan. The new one consumes 10 watts.

Now my question is, how do I find out how many watts my motherboard and current fan consume? I can't find that information anywhere. I need to know this, to know if my current PSU is compatible with the upgrades.

Do you have any manner of actual budget and alongside that, what type of use case is this PC for? Where are you shopping?

Hard to recommend doing any manner of update to a system bound in first gen Core.

My budget is 30 US dollars. That is enough to buy the three components I specified. The GPU has 0.5GB of memory and 650Mhz of core clock.

This PC will be used only to browse the internet, watch 1080p videos and images and sometimes do backups of 500GB at most of data.

Considered a fresh OS install?
What OS is it?

Lol, I was also going to ask what OS you are on?

Windows 7 Ultimate N. I'm still researching Wich OS is best for me. I want Windows though.

I don't think a fresh OS install will help, as it doesn't has any program installed, other than basic things like a browser or Paint.
The drive isn't used at near it's maximum capacity, and there aren't too many files nor folders.

I would consider your trying one of the lite versions of various Linux distro on this. It will still be slow, but less overhead should make it run a little better, and it will be more secure. W7 is basically dangerous to run at this point on a PC with no power to also run AV even if another program was installed.

You should save your $30, save up a few more $30, and look for a used business platform from Dell or HP in the 4th gen at minimum, and really as new as possible at this point. Even that is OLD, but makes a world of difference. $100 could go a long way here.

Windows 7 Ultimate. Dare I ask where this $400 OS license came from?

But....any ad blockers? A lot of times, ads can bring a poor CPU to its knees.

Thank you for your help, but I really need to stay with Windows. This isn't a PC for me, it's for someone else who doesn't want to buy a new PC.
I will try installing AVG antivirus I think the PC will run it easily.

I don't know where it came from, because I don't own the PC.
No ad blockers. Are there someones you suggest?

With this units proprietary motherboard and build, changing to an SSD is the only "real world" performance improvement you can make hardware wise. Anything after that is just throwing away good money on nominal improvements...at best...that would be better used toward a new box. Just my friendly. 👍

FWIW...I stretched my 775 build for 14 years before replacing it.

What is your current processor?

Intel core i3 550. The main reason I want to replace it with i5 760 is because of the cores. The i3 550 has 2 cores and 4 threads, while the other one has 4 cores.
When I'm browsing the internet the PC is at normal speed if I'm using only 1 tab. It slows down when using more than 1 tab.

Right now I'm wondering if I should acquire the i7 870, because it has 4 cores and 8 threads. I'm not sure if faster octa core speed will help.

Hey there,

Hmm. I think you are slightly missing the point the others are making. Other than the SSD and ram, as you've done, nothing else will help your issue. Do not waste any more money on it.

The other question is, you do realize that even with an AV app, because you are running Windows 7, the PC will be open to major viruses, trojans, malware, and ransomware? You should not give this to someone as it may actually compromise their privacy in a major way, if they are browsing on the internet.

The processors are not that different.
Here are the passmark ratings:
i3-550 4 threads total rating 1609 single thread rating 1339
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i3-550+@+3.20GHz&id=739
i5-760 4 threads total rating 2630 single thread rating 1292
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-760+@+2.80GHz&id=773
i7-870 8 threads total rating 3131 single thread rating 1383
https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-870+@+2.93GHz&id=832
The total rating happens when all threads are 100% utilized.
Not a likely occurrence for desktop work.
The single thread performance is the more important metric for desktop work.

I see so little difference that a change does not look like it would be effective.

How much ram do you have?
Is it running in dual channel mode?
CPU-Z will tell you.
If you do not have at least 8gb of ram in dual channel mode, that could be your problem.

Why is the single thread rating higher with the i3? With turbo speed the i5 reaches 3.3Ghz, while the i3 reaches 3.2Ghz.

According to this other website, the i5 has slightly faster single core speed.

4x2GB of RAM, CL9 and 1666Mhz. According to the manual, the motherboard does not support more than 8GB of RAM nor more than 1666Mhz.

Passmark is the result of many individual users.
There will be some variation in results.
Userbenchmark is considered as junk science.
Regardless their comparison is comparable.

I think you are as good as you are going to get with your current setup.
