Hi, I have a dell dimension 8400, with a Pentium(R) 4 CPU 3.20Ghz and nvidia 8600Gt and i want to increase from a 350 watt power supply to possibly a 400 but i dont know if my computer and etc can handle it. Sorry if i didnt add all the neccesary specs.

More about : advice power supply

Why do you need a bigger psu? Are you planning on upgrading another component as well?

I had been having some issues with certain games and chalked it up to not having enough power running to the graphics card. I was told that the graphics card that i have requires atleast 350 so i was thinking that it was not reciving enough power to run it to its fullest. Otherwise if the pc is receving enough power to run then i wouldnt upgrade.

what are your full system specs and psu specs (rails and amps)?

An 8600GTS 512mb uses little over 60w under load whilst an 8600GT uses less than 50w and Dell PSU's have historically always been slightly more 'fruity' than the label would suggest, so what kind of issues have you been experiencing?

Never heard them described like that before :lol: 
But , yes, the 350w is more than capable of powering an 8600GT

Just random frezzes that last a split second. I at first thought it was my wireless but iam getting a constant 65 mbps. I was also told from other gamers with the same graphics card that in cod4 i should get more than around a steady 40 fps with the 8600, but maybe my proccesor is whats slowing me down, its was the only thing that failed on SystemRequirmentslab.com. Oh almost forgot i was starting up my pc and recivied a error that said pci bus slot 1 running in x1 mode dont know if that has anything to do with my issue.

If you are playing online then the split second freezes are more likely ISP/network related than PSU related and the FPS rate in COD4 is likely to be being stifled by your CPU which is getting on a bit by today's standards.

So the frezzes are something that may be solved by a direct connection instead of wireless possibly? And just one last one sorry for so many lol, but the message i got during start up talking about pci slot 1 operation in x1 mode does that have anything to do with my graphics card?

More than likely.

Probably but I'm not sure what, have you checked in BIOS to make sure it's on PCIe 16? or reseated the card to see if that causes the pc to see it as x16?
October 29, 2009 12:30:50 PM

I checked it and it says Bus interface : PCI-E x16@x1
I just recleaned my pc and iam pretty sure that its been seated correctly

There's your problem.
Try a clean driver install ( use a driver cleaner )

Okay, gonna try that now
October 29, 2009 1:24:43 PM

I gave it a clean install and used driver sweeper, also I opend the case and checked the card again and its in there. Iam still getting the PCI Express operation x1 mode.

OK, maybe a cmos reset will do it.
Shut the system down, remove the power cable, remove the battery from the board and switch the jumper from pins 1-2 to 2-3, leave it like that for a couple minute's then reverse these directions.
The jumper is located on the lower right hand corner of the board.
You'll need to reset the time and date after rebooting.

Have you tried looking in the bios for pci-e options? I'm not sure it will have any as you have a dell board, but its worth a try. Also, are there multiple pci-e slots on the board, and if so, which one is your card in?

I looked through the bios and i have a option about an option about pci and pec enabling. I have it in the black slot for lack of a better term its really the only one it fits in, I have had it in there for a while and recently cleaned the pc and now its doing this is it possible that something is physically blocking the slot and the card from connecting ?

There's only 1 PCIE x16 slot on your board, so nothing to worry about as far as having the card in the wrong slot.
Have you recently done a bios or chipset update ?
Which driver version are you using ?

And iam on the 191.07 for the graphics card.
I have never updated the bios or the chipset myself.

I'm not sure this will work, but it might, so I recommend you try this if you haven't; reseat the card, as in pull it out, if you have a can of compressed air, blow out the slot with it (otherwise you can try a vacuum, but be very careful not to actually touch it to the mobo itself), then put the card back in.

Unfourtanetly I have tried it already with compressed air. I cant even see anything in it.

191.07, is this the same driver you were using when you started the thread ? Or did you download it when you did the clean install ?
October 29, 2009 5:26:19 PM

Is your computer still under warranty by dell? If it is, you may want to consider taking it in to be looked at. Honestly I've never seen anything like this before (a PCI-e gpu only operating at 1x while in a x16 slot). I'm sorry to say I'm at a loss for whats wrong. I will research this a little more tonight after work, and I'll tell you if I find anything.

Same driver version diffrent download. Should i try starting the pc without the card and will that possibly give me an idea if its the card or something else.

Pretty sure its not my pcs about 5 years old. Thanks for trying though. Iam thinking about calling nvidia and possibly maybe dell i dont know seeing as how dell loves to suck money out of you some times. Maybe compusa will be able to offer some insight.

If you start the machine with no card it'll probably scream at you.

Best thing would be to try the card in another system, I know not everyone has multiple systems, but maybe you have a buddy with a computer who would let you test it.

One other thing, do you have the original card from the system ?
October 29, 2009 5:33:36 PM

^ Agreed on that. If it checks out ok on the other system, its probably your board, and from the five minutes of research I just did, this seems to be common for dell mobos; most were fixed by reseating the card, but in some cases, only x1 operation was supported.

Lol my luck turns around huh. I actually have a outdated dell laying around so ill test in there.
October 29, 2009 5:35:11 PM

Just a quick question; is this the same gpu that came with the dell, or did you add it later?

I never experienced it on a Dell board and I've had many.
Several months ago I upgraded an 8800GTS ( on an Asus board ) to a GTX260 and had it happened, can't for the life of me remember how I got it working correctly.

That i may but i just moved so its all packed lol. And i just found out the old system i have has no pci slot
October 29, 2009 5:40:40 PM

Do you know anyone who might let you borrow their comp to test your gpu? That would be your best bet right now, just to determine if its the card or the mobo (I'm guessing it's something wrong with the mobo, though, but it could be both).

Not atm unforutanetly. I mean would it help if i gave you a pic of the graphic card's edge connectors?
October 29, 2009 5:48:09 PM

You could try it again; provided you don't discharge static, it won't hurt anything.

I mean it worked up untill couple of days ago,I have proablly had the card for a year.
October 29, 2009 6:15:13 PM

I mean is it possible that it operating in x1 mode is normal? And am I going to experince a decrease in performance?
October 29, 2009 6:18:36 PM

Unless you have a pci-e x1 card then no. So have you only been getting glitches in your games for a few days now, or has it always been like that?
btw; the x1 mode operation will reduce performance in comparison to a full x16 link.

I used to be able to get around 60 fps steady on lowest settings in cod4 and now iam fighting for a constant 35-40 on lowest settings including the smallest resolution. Its only been like this for a few days. Its happen once before a long time ago and i didnt even recognize it and then it went away and now its back. Even the temp is nice its running 50-51 c
October 29, 2009 6:57:35 PM

In cpu-z it says link width x1 and max supported x16 dont know if this helps
October 29, 2009 7:23:06 PM

Besides cleaning the pc, did anything else happen to it (ie. driver updates, any new hardware at all, etc.)?
