Low Profile, Low Power

I'm having trouble finding a graphics card I can use for my PC, because it is a slim tower, and has a bad power supply. I'm not sure whether the power supply is 250W or 300W. I bought a Galaxy GT9600, but I had to send it back, because after about 2-3 months of use my computer screen would go blank. They are suggesting to give me a GT430 as a replacement, but I current have a 4350, and it wouldn't be much of an upgrade, if any. Can anyone suggest a graphics card that would work to almost the equivalent or better than the GT 9600, that is a low profile and low power card. I was looking at a GT 240, but I'm not sure whether it's good or not.

GT9600: http://www.galaxytech.com/en/productview.aspx?id=46
GT 430 (That they suggested to give me): http://www.galaxytech.com/en/productview.aspx?id=384
GT 240 (The one I was looking at): http://www.galaxytech.com/en/productview.aspx?id=231

If another card is able to be suggested, that isn't said here I'd want it to be under $100.

Anything more powerful than a 9600GT will also use more power. Given that your power supply (PSU) is 250w - 300w, I wouldn't even recommend running the 9600GT. Sure it can, but you are stressing the PSU too much which shortens it's lifespan.

I assume you are limited to only Galaxy products so... the GT 240 is your best choice. It uses less power, but it's also less powerful. Your other option is to buy a more powerful PSU.

Also, when does your screen go blank?

My PC would start up, after about 10-20 minutes my screen would go black, but the computer would still be running, I've done many different things to try to fix it, but nothing worked. Other times it would last for about an hour or two, while I was playing a game, the same thing would happen.

Also, if I were to upgrade my PSU, how would I know which would work with my PC.

I would say the video card is faulty. When it happens in games does the computer lockup or do you still hear the game running?

A "slimline" PC may use a micro-ATX PSU, but it depends on which slimline PC you have. It should have come with a manual that identifies the various components of your PC in a simple diagram. You can also look at the PSU's sticker which might tell you if it is a micro-ATX, micro-ITX, micro-PS3, SFX12, TFX12...

Okay, so your PC crashes. Generally, that can mean your operating system is unstable or your PSU is faulty. Since you have a low powered PSU to begin with to power a 9600GT, then I would say your system is drawing too much power than the PSU can provide.

Generally, that causes the PC to crash, but it can also cause your PSU to overload and die. Sometimes when a PSU dies it can send a surge of electricity to your other components. If you are lucky, then only the PSU needs to be replaced. If you are unlucky then...

I found a PSU call Silencer 500 Dell, it says it will work with my PC, but it's a little too expensive. Do you know what type it is? http://www.pcpower.com/products/description/Silencer_50...

It looks like a standard ATX12V form factor PSU.

What is the brand and model number of your slim form factor PC?

There's a greater chance that it's a TFX12V PSU. I don't think you'll be able to find any with a continuous power rating over 300 Watts.

The Dell Inspiron 530s uses a TFX type power supply. The PCP&C PSU you linked is compatible with the Inspiron 530, not the Inspiron 530s. It comes with a 250w PSU.

At best you can only upgrade to a 300w TFX PSU like the following from FSP Group (who is Dell's primary PSU supplier) for $35 + $9 shipping. It's still a bit lite for the 9600GT, I'd rather use at least a 350w PSU for that.

Can you take a picture of you current PSU's sticker and post it? It should look like the following which is from the PSU I recommended:

At this point, it's starting to seem as though I'll have to get a new computer if I want to do anything with gaming.

You can buy a new PSU like the Seasonic mentioned above; I didn't see it in my search @ newegg, I might have only filtered on PSUs that are in stock. That should allow to play games in the short term.

Buying a new PC is better for the long term especially if you avoid anything that says "slim". That usually means it does not come with a full size ATX PSU. Which means your choice of video card and PSU upgrades will not be limited.

Well, getting off of the subject of new PSUs, how does a GT430 compare to a Radeon HD 4350?

The GT430 is roughly between the HD 4650 and HD 4670 in performance. Another way to put is pretty close to the HD 5570, but not quite.
