right now i have a radeon 9800 pro graphic card. the problem occurs when i play games such as Counter Strike and Rakion and not while im watching videos. While in gameplay, the game suddenly freezes and the sound effect constantly plays over and over. Recently the same problem occurs but the screen turns black. And even my case fans blink occasionally.

Hi,

Oldmn has a pretty good theory on this one. Why not list the brand name and wattage of your power supply? This might help us to pinpoint some issues that you are having.

Hi,

I found this information on your power supply:

+5v:25a
+3.3v: 20a
+12v: 15a
-12v: 1a
-5v: 1a
+5vsb: 2a

The model number is kc400

I don't know anything else about your rig, but this power supply with only 15a on the 12 volt rail is very, very weak even when performing at it's peak. I would suspect that it would not be powerful enough to pull your rig and video card. Might want to post what else you have like motherboard, cpu, drives so we know more about your setup.

Hi,

IMO, way too much power needed for 15 amps on the +12 rail. Your power supply just does not seem strong enough to cut it. That would be my best guess.

Hi,

That could be part of your problem. Take a can of air and make sure that it is clean and see if it will go. Otherwise, I would replace that thing, because you might damage the card if it gets too hot.

Similar problems, Radeon 9800se Crashes

Hey
I've just purchased a new Radeon 9800se (256) graphics card and I'm having similar problems. I've tried keeping my compiter as cool as I can, by taking off the case panals and sticking a household fan in front of it (lol) and still it crashes. Having reading many peoples problems many people are saying that it is a lack of power supply which is causing these problems. This is the same model of power supply I have, Thought that this pic would be of use as it has all the specs on - so my question is, Is my power supply too weak to run this graphics card? A speedy responce would be greatly appreciated, Thanks on advance.

Hi hounddf2,

It is very hard to tell since we don't know what computer you have that takes how much power. However, with that card, I would never try to pull it with less than a quality 450 to 550 power supply. When I say quality, I mean either an enermax or Antec power supply. Don't ever get an off brand that sells for 50 bucks, or you will regret it.

The ATI 9800 takes a bunch of juice to work properly and the power supply you have only has a total of 13 amps on the 12 volt rail. That is not much.

Other than that, we can kind of look at your issues if you want to start a new thread and that way you will get more help. If you do that, send me a PM with the thread link and I will take a look at it. If you post a new thread, please post your computer specs, plus this link you just posted.

@ hounddf2
Welcome to TSF:smile:
You didn't post your system specs, but I would guess that your PSU is underpowered for your system unless it is 5 or more years old, in which case you might be better off getting a new one anyway.

My new favorite PSU to recommend is the Antec SmartPower 2.0 SP-500 500W. At ~$76 delivered, it is the cheapest quality PSU I've seen. You may find it cheaper if you search a bit. Don't waste money on cheap generic units. Get a quality unit that will last you and not cause problems.

Keep us posted with your progress

Hi,

Please has suggested the Antec 500 as a great buy and they are. He has given you good advice.

I am using the Sonata II case with an Athlon 3700+ San Diego chip and it has an Antec 450 that came standard with the case. It runs like a charm. I also have an Antec Sonata I rig for my spare computer with an Antec 380 in it with a Pentium 4 2.8, and it works well. However, for the more powerful CPU that I purchased, I moved up to the larger power supply. I just think that you need to go higher if possible so you won't have to do this again in a few weeks when you want to add something to your box.

I would also suggest you take a look at the Antec 550 which is about as good as it gets for the price range. Might want to check out Newegg.com or ZipZoomFly.com and see, because they have been running specials for the past couple of weeks on these supplies (darn, why don't they run specials when I need one) that are high quality. Again, don't settle for anything but an Antec or Enermax because of quality issues.

Post back if you have questions or we can help in any way.
