The Eco edition to the 9800GT draws 40% less power then a normal 9800GT. Now if this is true, this also means I should be able to use this in my Dell PC that comes with its 305W PSU.

What do I need to look out for on the side of the PSU to confirm that the amps/rails are enough to juice the PSU aswell? (The config is in my sig.)

Thanks.

305 watts / 22 amps combined on the 12v rails is plenty for the low power 9800.
The only issue, other than the P4 choking the performance of the card, may be the age of the psu.

Yeah, mines only a 18a. O well.

Your Dell PSU has a total of 22A, not 18A because you have two +12v rails. To calculate how much amps you have total, you would take the maximum amount of watts that both +12v rails can handle and divided by 12.

264 Watts / 12 = 22A

You should be able to use the low powered 9800GT without problems and it looks like a single bracket videocard. You should be fine.

P.S. I have the same Dell 305W powersupply.

Wow, how did you figure out the specs of the PSU? :)  I spent ages on google trying to pull up some info.

^ He opened the case and read the stickered-chart on the DELL PSU.

I also used to have the same PSU, 18amps on 12v1 and 18amps on 12v2, 264wattage total coming out to 22amps combined output.

It's fairly decent for a Dell...as he said, the main issue is aging and degraded capacitors.

Hi, alright I just went out and got the card, and I'm useing it right now as I type. I'm just worried to be honest. I'm worried I'll blow out the GPU along with everyone else. I know you guys have said its OK, but hmm.

any more advice? Should I be this worried? I wanted to start a game to begin playing, but I don't want to right now.

Sorry for being a little crazy.

Hmm, I'm having a strange problem. When I'm trying to play CoD4 it freezes up after 5 minutes of gameplay. For example, it begins ti freeze, will stay like that for around 5 seconds then unfreeze, then freeze again. It will repeat this till I restart the game.

Any ideas?

Anyone? I also tried attempting to play HD videos on YouTube and the thing stalls/freezes/lags like hell when doing so.

I also installed/updated to the latest drivers. Hmm...

Ummm...That shouldn't happen.
See Gfx card temperature.

Well it may be a possibility that the 305W PSU is not providing enough power.

Check your card in friend's or your relatives PC that has a larger PSU.

Try underclocking the card with rivatuner and see if the problem goes away.

What if your powersupply was 300W will it matter?

Is it a Dell 300W? Or any 300W? If so... DO NOT DO IT! I had a 550W ColorIT PSU that I thought was fine but it fried out my entire system! I cheaped out. And paid big. Just like everyone else that would tell you the same. I never thought I would become a part of that croud :sarcastic:

On the side of the PSU, it should mention amps. Mine was 18A amps (22A in total, but thats another story.) Look for the highest figure in amps, and report back that figure as this is what is important, and not watts. If you have the PSU in a machine that was running low spec hardware, you may have a PSU with really low amps.

Also, are you sure you have the Zotac "Eco" GPU? this is inportant as a normal 9800GT will suffer and could fry out.

No it dosn't matter about watts. As I said... I need to know the amps to tell you if it will work with your PSU. Just take of the side and take a peak... If it says 18A or anything higer on the 12V rail, then pat yourself on the back and enjoy your new GPU. If anything lower, I wouldn't suggest it for 300W.

If you give me the model number of your Dell, I can tell you straight away. (Dimension XXXX?)

You make life difficult... You own a Inspiron Desktop 531. Problem is, I can't pull up any specs on the PSU other then it being 300W. You need to tell me the amps.
