You need a 2x 6pin to 1x 8pin adapter, and it should work with that psu ( the gpu requires 200W max )

@haytham_kamel​ a rtx a4500 would be quite powerful vs the t5600 specs and will be bottlenecked by the cpus (depending on the task), I suspect.

What is the current gpu in the 5600 ? (cpus / ram ?)

@haytham_kamel​ understood. Well, a rtx a4500 would cost way more times the value of the t5600, and be partially exploited as in used. There would be some level of bottleneck depending on the task.

Unless you have a really good bargain chance for a rtx a4500, if your focus is leaping from a k4000 to something in the class of a rtx 30x0/40x0 ( to give you some comparison, your k4000 is more or less 3 times slower than a simple gtx-1600 ), and the focus is on a quadro level card .... I would look for a RTX A2000 , that will be cheap ( used ) and more balanced for your computer ( the card will be bottlenecked too, but will not cost you a kidney like an A4500 ).

To give you a bit of a comparison, an A2000 is in between a RTX 3050 and a RTX 3060ti (for gaming) and will have the professional drivers that photoshop and such will take use of for extra speed

@jesse199x​  The RTX A2000 doesn't require 2ndary power and tops at 70W under full load , while performing practically like a 3060Ti, sort of anyway. Insufficient power is not a factor.

@haytham_kamel​ 

Depends also what you plan on using it for.  Google system requirements for apps/games you use the most.

1. RTX A2000 = 70w
2. RTX A4000 = 140w, 1x6-pin connection
3. RTX 4000 Ada = 130w, 1x16-pin connection (not sure why 16-pin); also saw 6-pin  May have to watch the model you get.  This one is 6-pin.
4. RTX A4500 = 200w, 1x8-pin connection

It looks like they're all compatible with the exception if an ATX 4000 model comes with 1x16-pin connection.  I am questioning the A4500 due to it's 1x8pin connection.

Hi @redxps630 ,

As I might recall from your posts, if a PSU has a 6-pin connector for GPU's, a 6-pin to 8-pin adapter can be used for GPU?  Or am I thinking of 2x6-pin to 1x8pin?

Wanted to ask since I'm not sure about the RTX 4500 compatibility.  Please see above posts.

@haytham_kamel​ 

I did somehow manage to miss that mazzinia said "2x6-pin to 1x8-pin adapter...," making my adapter question unnecessary.

From one of your posts, I was under the impression your PSU just had one 6-pin connection for GPU's.

Hello, 

sorry for taking so long. An A4500 for 800 seems a good price, especially if new open box.

The A2000 doesn't require extra power , the rtx 4000 personally i would discard it from the comparison, being one generation older. The rtx A4000 uses 140W with 1x6pin connector  (so fits your situation without any extra adapter ), while the A4500 uses 200W and requires 1x8pin ( so you need to convert the power cable ). In theory all 3 are ok with that psu, I think.

Now for the other part of the question, the issue is that the cpu and bus is slower than that of a current system, and will prove a limit to obtain the most out of the cards.

Rest of the equation is what kind of programs are you going to run. Cpu intensive that use the gpu, or gpu intensive that don't rely on the cpu , and what prices you manage to get for the various cards.

Personally I would say : what about an A2000 and using the difference to swap the T5600 with something more recent maybe ?

All rtx A cards ( A2000 , A4000 etc ) will work well with the Adobe apps. From the Adobe creative cloud faqs

"For optimal handling of more complex scenes, we recommend the new NVIDIA graphics card technology of the RTX series. Preferably RTX A2000 with 12 GB, RTX A4000 with 16 GB VRAM or a RTX A5000 with 24 GB VRAM"
