Or the low profile AMD 250

It's 80 euros, it's too much for me. Also need something in Europe. Will my PSU of 305w haddle them?

What are the prices on the following:

AMD 7730 low profile

Nvidia GTX 640 low profile

Anything lower than those cards and you won't see much improvement in performance.

Your PSU will be able to handle any of the cards listed above.

You better measure it! The CPU cooler is in the way of most of the longer cards out there. You dont need low profile but the length is a concern.

The minitower version of the 755 DOES need a low profile, as does the SFF 755. The Mid tower 755 is the only one that can accept a normal expansion card I believe.

Sff needs low profile but I don't think the mini tower does. If so, It still needs a shorter than normal card

hans_pcguy · Apr 25, 2014

I thought 755 came in USFF, SFF and Mini Tower.

Just checked there are 4 versions Usff, sff, mini tower and mid tower. And YES you do need a low profile. I have used many of these motherboards in different cases and they NEED SHORT video cards. Make sure you measure. Not extraordinarily short cards but most good cards are too long. Not really too long but if the cooler sticks up more than a half an inch towards the back it wont fit. I believe they will also only supply 17 volt to video card without the extra power plug. I have used SOME Radeon 4670's on these, but I have one now that wont fit. All Radeon 4650's that I have used have fit. I don't know how big the newer Radeons are but if they have the heat sink/cooling fan towards the back they will not fit.

You could also use one of those flexable pcie extenders. You would have to fabricate a way to mount it in there but then you could use a regular height video card also. I have done it before.

I was looking and reading, and the end I am confused with exact form factor.

There is no Mid Tower, look below and identify yours

MT - 7.5 inches long single bracket and a few other parameters
SFF and DT - low profile single bracket
USFF - not upgradable.

Power Supply upgradable only for MT.

Can we provide links to Amazon UK, what is approximate conversion between pounds and euro?
