Hey guys I have a serious question. My friend wants me to him with a new GPU. I have suggested him a GTX 750 ti. He thinks that the GPU won`t fit onto his PC. I am just double checking.
His PC isn`t old.
He has an AMD Video Card

HERE IS THE INSIDE OF HIS PC

Thank you! It is safe to assume that your system does not pull more than ~155W at load, add 75 to that and we are looking at ~230W draw at full load. The 350W PSU should be able to handle it just fine! Happy gaming!

A fair point, but that can be dealt with later. Primary issue is finding out if the motherboard is compatible with a PCI Express card since that was TraxNInja20's question in effect.

Greetings!

Upon close inspection of the pics, it appears the system has an FSP Group 350W power supply, and the motherboard does have PCIe slots for the graphics card. Some specs would help, but I think you will be OK with the GTX 750Ti for it will pull its power straight from the PCIe slot without needing a separate connection from the power supply (which I doubt the FSP has). It appears this is an OEM computer and not custom built and often there is no additional power connectors for they were not required for the design of the system. The 750Ti is a great choice for these kinds of systems for they afford plug and play without having to upgrade the power supply.

In short: Should work fine.

Hope this helps!

p.s. Please clean that computer before it fries itself...

Whether a GTX 750i will physically fit inside the system case is another matter, it may be a compact or SFF case rather than a full-tower or mid-tower. Plus, the GTX 750Ti is a "dual-slot" card so that's another factor which may prohibit it's use on some motherboards, especially those fitted to pre-built systems.

I can't tell from your pics.

As far as I can see from pictures 7 and 9 in the photos, it appears to be a mATX motherboard in a mATX sized case (4 PCIe brackets on the case) with nothing plugged into any of the PCIe slots. So dual-slot won't be a problem. There are many iterations of the 750 Ti, and some are large and require a separate PSU connection, but many are quite small and will not require extra power, so as long as you aim for one of that variation it should be fine for the smaller ones won't extend past the width of the motherboard, and in the case in the pictures there is plenty of clearance all the way to the front of the case (picture 9).

p.s. I would also add an exhaust fan on the back of the case to contend with the added heat from the 750 Ti.

I can see from the last image that the motherboards PCI express slot runs at x16, which is good. Going forward, further info on the motherboard make and model would be required.

However, I am slightly concerned that the current power supply does not have enough amps on the 12v rail to equip the GPU (GTX 750 ti) with enough power. I have read you need around 20 amps on the 12v rail; for the GTX 750 ti. The current PSU has 16 amps on a dual 12v rail, single 12v rails are always best going forward in potential upgrades. Therefore, I see a new power supply will be needed.

On a side note, a can of compressed air would be good on clearing out all the dust within the CPU heatsink and around the system 😀.

Nice catch! I hadn't looked that closely at the PSU. You are correct, a 750 Ti requires 20A and the PSU is only providing 16A. There is a real issue there. The PSU will need to be upgraded to run a 750 Ti....However, upon closer inspection, it appears the power connection to the motherboard is not a standard 24 pin (common for OEM builders to utilize proprietary wiring designs), which would make upgrading the PSU nearly impossible without some funky hacking and splicing. We may have hit a dead end with this one.....

I would agree (Adept) with the motherboard issue looking at the images again.. Looks like a 20 pin or some odd customized connector. So upgrading the PSU would not solve the issue either.

Looking at the system it looks stock i.e shop bought, which when I was getting into PC's, I went for that approach too.

Even though it would probably cost a bit of money. I would suggest thinking about potentially building a new system (Your friend), it would be the only way to get you started in potentially upgrading for the future.

However, if you still want to upgrade to a GPU; temporarily. I would suggest getting a GPU that does not require 1. Additional power from the PSU and 2. only pulls its power from the motherboard. These types of GPU's are mainly for home-entertainment systems, but can still play some games. I remember having a ATI 5450/ATI 4350; showing my age 😀, when I was a noob at computers, however that was all I could upgrade to, due to the limitations of other hardware.

The negative about that is typically, it will not deliver brilliant performance in games. However, it will be able to play more simple games like the Value series of games etc...

That's probably the best I can produce out of this question, unfortunately.

Y'know, this has really got me thinking and so I have been digging a little deeper and it appears the 20A thing is a little confusing. I have found others calculating amperage through Watt requirement. The 750 Ti is as 60W card, which when divided by 12v, gives us an approximation of 5A of draw. This makes sense to me and makes me think that maybe the system can actually handle a PCIe powered variant of the 750 Ti. This may actually work!

Doing a little more digging...I have not been able to find truly verifiable evidence of the 20A requirement outside of forum discussions...

Just found this post and I am feeling quite strongly that it is correct for the math makes sense for electrical draw...I am a journeyman electrician on the side and this math is correct for every other power consideration I have ever worked with:

http://www.tomshardware.com/answers/id-2607904/gtx-750-amp-requirement.html

In short, a PCIe powered GTX 750 Ti will work in this computer. The PSU is rated at 350W (though it is likely to under-perform a bit being in an OEM build), which should be ample for if the 750 Ti is pulling 60W, that leaves 290W available for the rest of the system and I doubt the CPU, RAM, and drives are yanking anywhere near that much. Even if the card pulls the maximum of 75W from the PCIe under load, you should be fine.

I mean I am no electrician, so I'll leave that side to you :). However, in my opinion when I see a PSU brand that I do not recognise, I would be weary about putting too much load on the 12v rail, as it is most likely going to be a cheap-ish PSU and designed for those stock components in the system; with some additional head room.

Nevertheless, if it was a 350 watt PSU from Corsair etc.. I would probably say yeah that would be fine, just because the background of Corsair presents good quality PSU's.

However, that's just my opinion. But I trust your math. 😀

@Seaweed Monster: Your opinion is totally valid!! I also fall into the same category of thought as you regarding the PSU...unknown brand=distrust🙂 By capability it should be fine, but it is an excellent point to consider the quality of the PSU. In this case there is no PSU upgrade option, so the only thing to do is to install the graphics card and monitor how it is working with the system (stable under load) for the first few days/weeks. It is a junk power supply, but it has worked this long and the overhead should be sufficient. If there was an upgrade path for the PSU, I would definitely be pointing them toward an EVGA, Corsair, etc. 🙂
