I'm starting to think i'm not getting enough juice from my power supply. before when i was running my 6600 gt i was using a 5200fx. anyways, when ever i'm on my desktop and start to move around the cursor it starts to skip around and move all laggy. games play pretty decent but i never got this experience with my 5200fx.

btw, i'm using a ultra x connect 500 watt power supply, shouldn't it be enough power?

Your power supply would entirely depend on what hardware you have, there is a formula for how you figure out how big a PSU you will need **although i dont know it off hand sorry** and as a rule of thumb for me it if it works out to 500w then i go with 550 or 600 **just examples**. It also will depend on if you overclock also, i believe , not sure on that point as i dont OC **YET **

I can't see you having power issues with a 500W system unless you have like 6 HDD connected, 7 case fans or a really funky w/c setup (or phase change). I run an Ultra Xconnect 500W too, I have 2 IDE HDD, a DVD writer and ROM, an x700, 4 case fans, a Hardcano13, and a whole whack of USB stuff attached. No problems although my rails are lower than what the review sites have. Oh well.

And power issues don't make the mouse laggy lol. Did you rebuild your system after you put the new vid-card in? As well, make sure you have your AGP in the BIOS set to 8x or Auto, not a lower setting. Personally it sounds more like a driver issue / windows issue than anything else.

It COULD also be spyware/adware, or errant windows processes. Antivirus can cause huge CPU spikes causing ghosting, etc. It also could be your video card is on the way out or over-heating. My old 9800 pro started artifacting, and ghosting and crashing after I oc'd it and cooked something. Yay for big-store return policies and dummie techs who just nod and smile when I say artifact.

So in a nutshell... lots of things it COULD be, I don't think your PSU is one of them though.

I don't think it's ur PS. I agree w/ the advice above ^^^^. But just to calculate power needs heres a linky to the calc program. http://forums.pcapex.com/showthread....er+supply+calc
