I have a pc Lenovo A62 , it is prepaired from where I bought it (here are the specs : https://support.lenovo.com/gr/en/solutions/migr-70037 )
CPU:Athlon 64 x2 4800+
RAM: 4GB
GPU:Radeon HD 3100
I want to make it a gaming pc, not something very powerful, because it can't be. I want to make it a decent gaming pc , to play gta v, fps games etc. and not at high resolution and high graphics, I am ok with "low". I want to buy the cpu AMD Phenom x4 9850 and upgrade Ram. My question is : Can I put a gpu in this pc? I was thinking of buying for example a radeon rx 550 or something like that and I don't know if the pc will handle it.

Until we know the motherboard model, no word on whether GPU can be fit onto it or not. If it has a PCI-Express slot, it should theoretically work with anything. But if the slot is only PCIe 1.0 or 1.1, GPUs older than the HD 7000 series/GTX 600 series might not work, but it's not definite.

That being said, the Phenom X4 9850 will probably only barely manage mediocre framerates at lowest settings in GTA V. I don't think it will provide a decent gaming experience.

If you're already spending money, you really should save a little and get a new budget rig with something like an Intel Pentium G4560/G4600, 2x4GB DDR4-2400, H110 motherboard and a RX 560.

But that's up to you and it should somehow work out. Make sure your power supply...

First, not sure if you can use the 9850, found this Lenovo support forum post. The 9850 is not listed in the table of supported CPU's.
https://forums.lenovo.com/t5/ThinkCentre-A-E-M-S-Series/ThinkCentre-A62-CPU-support/ta-p/476261

Physically it might match but maybe the BIOS doesn't support it, I don't know, I cannot find any info. The Phenom X4 9750 is supported though and it is pretty darn close to the 9850 in performance. To be safe, that is what I would go for.
http://cpu.userbenchmark.com/Compare/AMD-Phenom-9750-vs-AMD-Phenom-9850/m2439vsm2967


Next, the specs show that it ships with either a 220W or a 280W PSU, this is quite small. As well, PSU lose wattage capacity as they age. The Athlon 64 x2 4800+ is a 65W TDP CPU while the 9750 is either a 95W (pn HD9750WCJ4BGH) or 125W (pn HD9750XAJ4BGH) CPU. Note the "WC" vs "XA" difference in the part numbers.

https://www.ebay.com/p/AMD-Phenom-X4-9750-2-4GHz-Quad-Core-HD9750XAJ4BGH-Processor/74074596
CPU comparison: http://

Either way you are adding power requirement and I don't think you can stay with your current PSU. Luckily it appears that it is a standard ATX12V PSU and the mobo takes a 24-pin and a 4-pin power connection so getting an aftermarket replacement should be easy. This would be a good choice for a budget PSU.

Your spec link shows that you need low profile, half length cards. You asked about the RX 550, it would be a good pairing for 9750. Here is a card that matches the requirements. Alternately you could look at GT 1030 cards.
https://pcpartpicker.com/product/XPwqqs/msi-radeon-rx-550-2gb-low-profile-oc-video-card-rx-550-2gt-lp-oc

As stated before, this will not handle GTA V or any other CPU demanding games.

The above is all true, and I believe you cannot call that configuration a "gaming PC" by today's standards. For playing older games it should be fine, modern games will have difficulties running smoothly.

So this can become a retro gaming PC, but not a modern one.

I was looking the phenom x4 9750 but I thought why not buy the 9850 or 9950. Although I will not go for 9850 and 9950, cause I can't. I will go for 9750. As for the psu I have a 450w so I don't have any issues with that. Now for the gpu, I can go with rx 550. I know I will have bottleneck because of the cpu, but I have compared these specs at gamesystemrequirements.com for gta v and it is ok at minimum. Can you suggest me any other cpu from the list of thinkcentre a62 that is better than 9750? And , you say that the rx 550 or gt 1030 can be put on this system?

The Phenom X4 9750 is the strongest supported CPU. The 9850 might work, but that's a gamble because of missing support.

And yes, the GPU should normally work, looked it up, the used 780V chipset has PCIe 2.0. So, 99% sure it will work out if your 450W PSU can handle it.

I'll repeat however that while it will just meet minimum requirements for GTA V, most modern games will struggle to run.

First, my ringtone is the Doctor Who theme ;)

The 9750 is the fastest CPU that can be supported on this mobo. Yes, you can likely load GTA5 but it will be pretty awful performance. Other games will probably play better, GTA5 one of the more CPU demanding games out there.

For the GPU, it states in the spec that half length, low profile cards are required. This means more than just the size of the GPU, be mindful of this in selecting a GPU. The one I suggested meets these requirements.
https://www.quora.com/How-are-Half-Length-Full-Length-and-Low-Profile-PCI-slots-different-from-each-other

The RX 550 and Phenom X4 9750 will not bottleneck each other so you will not have to worry about that.

Thank you guys both for all the answers. I really appreciate it. Thank you ZRace for your help on this pc and ,although I didn't want to make a new pc, for your help suggesting me parts for a new one. And ,of course, thank you imsqam for looking up all the details of the mobo and showing me all these sites for buying cpu gpu psu, to compaire cpus, for the supported cpus by the mobo (which I really needed) -I know the game-debate.com site but thank you- and for the details of the length of the gpus. Also thank you for telling me that I will not have bottleneck, which I could not know that.

One last question. I saw the site with the differences between the lengths of the gpus and I saw that the only difference is the size and not something else. Am I wrong? What are the differences and if I get a normal size rx 550 will it be ok or will I have problem? The case is midi-tower, so I don't have any issues with that. I am wondering because I cannot find a low profile rx 550 to buy and I have found this http://www.e-shop.gr/vga-gigabyte-radeon-rx550-d5-2g-gv-rx550d5-2gd-2gb-gddr5-pci-e-retail-p-PER.516860 and I want you to tell me if it will be ok.

Unless you swapped the PC to another case at some point, the Lenovo site clearly states you need a half-length, half height card. So with the original case, yes, you'd get a problem as the card might not even fit.

This link and picture might make it clearer.
https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P6BQSA0
http://cdn1.bigcommerce.com/server5200/0y972n8f/products/2015/images/7746/lenovothinkcentrea_11464_lenovo_thinkcentre_a62__5__59770.1449502629.1280.1280.jpg?c=2

Looking at the picture do you see how the slots at the back of the case do not go all the way across? This is the main physical difference, the bracket attached at the end of the GPU fits into one or two slots and then a screw secures the GPU bracket to the case. Low profile cards have a 79.2 mm bracket height while full height cards have a 120 mm bracket height. As well, the screw is in a different spot. You can't fit the full height bracket into the half height slot. Your RX 550 has the full height bracket.

The real question here is what length of GPU can really be used here. In looking at this picture
http://17c4dcd7f91259d8cc66-f5932f6db0039e8c02f89a70c334ff0e.r2.cf1.rackcdn.com/wp-content/uploads/sites/2/dtr-1957-557x501.jpg

there doesn't seem to be much in the way that would prevent you from using a card which is over the half length spec of 175.26 mm (6.9 inches). There is that heatsink just under the RAM slots but I can't tell from a picture. If you have the clearance and you are not too close to the heatsink then longer cards might be possible.

Couldn't find an RX 550 on your vendor's website but I did find this GTX 1050 Ti
http://www.e-shop.gr/vga-gigabyte-geforce-gtx1050-oc-lp-2g-gv-n1050oc-2gl-2gb-gddr5-pci-e-retail-p-PER.516859

The 1050 Ti will bottleneck somewhat so it is a bit of waste money wise. It will work fine, you will just have unreleased potential in the GPU. But this will max out the performance of you CPU.
https://www.newegg.com/Product/ProductList.aspx?Submit=Property&Subcategory=48&N=100007709%20600038363%20600038364%20601292087%20601292091%20601273511&IsNodeId=1&IsPowerSearch=1

It would be better to get a plain 1050 as they are cheaper but couldn't find one on their website. You can find lots of GT 1030 LP GPU's but they are even weaker than the RX 550. Not by much but weaker.

So we will finish with this statement/question. Are you starting to invest too much money into a dead platform/aging machine? Computers do have a lifespan and should die at some point. You will not get a good playing experience with some games like GTA 5 with this system as it is too weak. But if you are happy with going forward with this plan then enjoy.

I have this excactly case as the picture shows. I measured the size of the space on the mobo at the pci slot and the numbers are: around 46mm from the rear side of the case to the pci slot, around 90mm the pci slot(for sure ;)), around 45mm from the pci slot to the heatsink and around 28mm is the heatsink. Around is 1 more 1 less. Overall from the rear side of the case to the heatsink (without the heatsink) is around 180mm. As for the rear side of the case: overall is 175mm, but until that thing sticking-out is almost 120mm. I think that the rx 550 I showed you will fit, because the gpu is 170mm at length and the rear side of the case is almost 120mm. Please tell me your thoughts now with the numbers I gave you.

This vendor is very good. I buy things from there for over 4 years and I am very excited. I can return things I have purchased the first 14 days and they give me back the money, so if it cannot be installed in the pc I will return it.
