Hi,

I have "Cooler Master eXtreme Power Plus 500 PSU" and "Asus GTX 550 Ti GPU".... and the Graphic Card is recognized with problems by OS, and it's using generic VGA driver at 800x600, also the screen shows horizontal lines like a n old tv with bad signal.

The PSU specs:

Total Output: 431W

Output: +3.3V@22A, +5V@25A, +12V1@18A, +12V2@18A, -12V@0.5A, +5Vsb@2.5A

Rails: 2



The system requirements for GTX 550 Ti:

A minimum 400W system power supply (with 12V current rating of 24A)


I need to know if this PSU can handle this GPU.



Thanks in advance...


Luis

In theory it should work, but coolmasters powersupplies arent real good and it might not put out what it says

Your PSU should be able to handle that GPU.

Questions:
1. What is your OS?
2. Why are you running on the generic VGA driver? You should install the nVidia driver that comes with the card in the CD or downloaded from nVidia site.

Hi, Thanks for the reply..


1. My OS is Windows 7 64 bits

2. I didn't install the generic VGA driver, it's installed by default since the graphic card is recognized but with problems. I've installed the driver in the cd but it doesn't work because the GPU is not properly recognized.


Other specs in my PC:

- Intel DP43BF Desktop Board
- Corsair CMX4GX3M2A1600C9 DDR3 2x2GB kit RAM
- Intel Core 2 Duo E6750 2.66 Ghz
- Maxtor 250 GB HDD and Samsung 1 TB HDD

Did you connect the 6-pin PCIe power connector from your power supply to your graphics card?

Download drivers from nvidia site:

Hi,

Yes I did it. But I'm afraid this 6-pin PCIe connector belongs to a 12V rail that only has 18A instead of the 24A required by the GPU.

Can you post the link where it says the 550 Ti requires 24 AMPs.
nVidia site state the maximum GPU power for 550 Ti as 116W which at12V puts the AMPs to just about 10AMPS total.

This specification can be readed on one of the sides of the box...

I'll posting an image soon...

24 amps sounds more like what you would need for the whole system, with a GTX550TI installed

Hi,

here is the picture where can be clearly readed:

Does it mean that my PSU have to meet this requirement ?

That refers to the whole PSU & total for 12V. Your PSU have +12V1@18A, +12V2@18A so your PSU comply.

Can you give a screenshot of the part which state your graphics card is not properly recognized? device manager?
Also, can you try updating the driver via device manager also by automatically searching in the web?

Here is my PSU specs:

http://imageshack.us/photo/my-images/208/img01718201205...


Through investigation I found that the current rating formula is I=P/V (I=current, P=power, V=volts) so, for my PSU, substituting values is: I=360/12 => I=30A. So the total current rating for my PSU is 30A. But it is possible that it could be less than that, due to the quality of that PSU. Maybe less than the 24A that the GPU need. It is possible that is what's happening ???... or it's possible that the GPU is damaged ?


Tomorrow I'll be sharing the screenshots...


Many thanks for your interest randomkid!!

Cooler Master PSU quality is not stellar but not that bad either. So if it is powering up the PC, it is unlikely to be the cause of your GPU not being recognized properly.

Anyway we wait for the screenshot... we will know better from there.

If it was your power supply at fault, your computer would randomly shut down and show bad performance when put on load. Power supply issues don't cause drivers to malfunction. It's not your power supply at fault here!

Did you try reinstalling windows? You said you had 2 HDDs, why don't you try installing windows on that other HDD and see if it's fixed?

You haven't mentioned if you have downloaded an installed the latest Nvidia drivers. I would start there.

Yes. I have tried everything. Installing all drivers from Asus page, and from NVidia page, and some old drivers I have too. And always the same...

Do you have a friend with a PC? Maybe a relative? I'd try the card in their PC, because it sounds like it was faulty.

The OS was initialy installed in Samsung 1TB HDD, and I reinstalled it in Maxtor 250GB HDD. And the problem remains. The problem is not with OS, I think is something related with hardware or somewhat related with PSU.

I'll be posting screenshots soon...

Yes, maybe this weekend I'll be testing it in a friend's rig. I'll be posting the results..

Hi,

I was testing things with "Asus GTX 550 Ti" in my system.. I realized that installing the latest Nvidia and also the recomended Asus drivers crash the OS when loading or simply don't send any video signal when it suppose to show the login OS screen. However, installing some old drivers I have, for example 275.27 version from Nvidia, the OS do start, but not with the Nvidia driver, instead the OS uses generic VGA driver at 800x600. This happen when all the time the screen is displaying this horizontal lines everywhere.

I realized too that printing screen for save an image doesn't capture this awful lines I see, so I took some pics with my phone:

7- http://imageshack.us/photo/my-images/708/img01726201206...

Maybe next week I'll be testing the GPU on a friend's rig... I'll be telling you..

Thanks guys

Oh man... that looks awful. Have you by any chance tested the monitor itself with another computer or changed the cables? Specially since the print screen does not capture the awful lines, it may be indication that the graphics card render the image properly but not displayed correctly by the monitor.

Does the computer run fine wit the intergrated graphics? if so, its almost garunteed a driver or GPU problem

The monitor is well, I have an old Geforce 8600 GT, and works fine, the monitor is at least 4 years old, so it must be the GPU, maybe the VGA connector of the GPU is damaged or something.

Maybe I should buy a VGA to DVI adaptor to see if the DVI sends the same signal. It shouldn't be so expensive..

I don't wanna buy another PSU if my current PSU can do the job

The MOBO doesn't have integrated graphics, but I have an old Geforce 8600 GT and works perfect

There you have it. If the old GPU runs fine, than the new GPU is faulty.

It could be the PSU, but that's very unlikely.

Call the GPU Manufacturer, and tell them it isn't working. Make sure to mention that you tried a different GPU and it worked fine.
