Will this work together?

Ximon · Mar 25, 2014

It is the first tme that I am upgrading my PC. I have a Dell 545 MT. All the components now which are Intel Core 2 Quad Q8200 2.33GHz, ATI/AMD 3450 512 MB 64-bit, 8GB of RAM(unsure which DDR), DG33M06 motherboard and 300W power supply are factory (how I bought in store) and WIndows Vista 64-bit. I ordered a Sapphire Radeon R7 250 1GB GDDR5 128-bit ( http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8573342 ) and I will be getting a Seasonic S12II 620W ( http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096 ) which will replace the 3450 and the factory power supply, and I want to make sure if all this will work together? Will the new graphics card (R7 250) be compatible with the motherboard and the processor? Will 620 W power supply be enough (will it also have enough on the 12V rail for the R7 250)? Can I replace a 64-bit graphics card with a 128-bit one? If I have a 2.0/2.1 PCIe port, can I put in a PCIe 3.0 graphics card in? Will the new power supply be compatible with the new graphics card, the motherboard, and the processor?

P.S. Sorry for so many (some lame) questions, but it is my first time upgrading a PC, so I rather make sure couple times, than make a bad move, and be sorry. If you need more info on the computer, just ask

All motherboards are compatible with all GPU.
CPU and GPU do not interfere with each other in terms of compatibility.
SeaSonic 620W will definitely do the job, but also an overkill.
PSU do not have compatibility issue with any combination of components, unless it's too little wattage.

It will work.

IDontUnderstand :

By an overkill you mean that it is more than enough? If I will buy it it will still work with the components I described above?

Dark Lord of Tech · Mar 25, 2014

The SEASONIC is a great choice , and the right size , buy it , the extra power won't hurt.

IDontUnderstand · Mar 25, 2014

It will work, but you can save money by going with cheaper PSU like the one suggested by SR-71 Blackbird in the previous post.

IDontUnderstand :

Ok, thanks for clearing that up, I will go with the SeaSonic as it is a reputable brand, and as SR-71 Blackbird wrote, "extra power doesn't hurt". So just to make sure, all parts are compatible and will work together without any problems?

Sorry for so many questions, but as wrote before it is my first time making an upgrade, and I want to be sure, before I do anything.

As long as the card fits your all set.

PSU is perfect fit.

Ximon · Mar 25, 2014

You mean fit the case?

IDontUnderstand · Mar 25, 2014

Yes, and I'm pretty sure it will since it's a very short card in a normal sized case, but the best way to make sure is to measure the case by ruler and look for specs online to match it.

Update: Actually I'm 98% sure that it will fit as the GPU has the same length as its PCI-E slot, therefore it won't even extend further than your motherboard.

Dark Lord of Tech · Mar 25, 2014

The card should fit and i know the PSU will it's OEM sized like the one in his case.

IDontUnderstand · Mar 25, 2014

BTW, if this card will be an upgrade if you can afford it.

I arleady ordered the R7 250, but thanks for the suggestion. Thank you guys so much for your help, if I could I would pick both of your answers as solutions. People like you should work in tigerdirect, because people that are there now, told me different answers for the power supply (from 550W to 800W), and one person even told me that the graphics card will not be compatible with the PCIe 2.0 because the card is PCIe3.0. Again, thank you so much.
SR-71 Blackbird, do you mean physical fitment (size of the card)?

Dark Lord of Tech · Mar 25, 2014

We are all glad to help , thanks for posting on the forum , stop in again if you need more help.

Spread the good word about Tom's Hardware.

SR-71 Blackbird, do you mean physical fitment (size of the card)?

I will surely let others now about this great website.

Dark Lord of Tech · Mar 25, 2014

It's a smaller than average card , should fit.

Ximon · Mar 25, 2014

Ok, thanks.

One more question that just popped in my head, do I need any additional fans?

Dark Lord of Tech · Mar 25, 2014

No , you should be fine

Ximon · Mar 25, 2014

Ok,thank you again, and have a nice evening

.

Dark Lord of Tech · Mar 25, 2014

You too , thanks for coming to the forum for help.

Good luck with the upgrades.
