You would be just fine. The 8400GS is not a power hog, only needing about 3A worth of 12V power. Dell PSU's are usually quite high quality. I wouldn't doubt that you could pop a 9500GT or HD4650 in there without a hiccup, and they are both available in low-profile versions.

^+1...your PSU can handle more than a 8400GS...
IF you are planning only for a 8400Gs for now then dont change the PSU...
Change it only if you want to add a more powerful card - anything above 9500GT/maby 4670 or above...

Up to a 9600GT should work. I think a 4650 would be pushing it.

^+1 Yes...
4650/4670 both dont require additional power connectors as the 9600GT which implies it draws less power...

How come 7300GS uses more power than 7300GS SLI? Doesn't sound right. And I didn't know that a 4850 used more than 1.5 times the power of a 4830.

Rags, you talkin about the chart I linked? If so, I tend the think they got the 7300GS and 7300GS SLI backwards or something. I'll get the text version of that chart linked as soon as I find it...

This version displays 4850 as 110w and 4830 as 85w. And the 7300GS SLI uses almost twice the power as the 7300GS. So I guess this is the real deal. The first post, the image version, was wrong.

Power meter while im typing this ....... : 155W
Power meter when im playing GTA4 ... : 400W

This is with 10fans, OCed, WCed C2D with a BFG GTX285 OC2.

Youll be fine with the PSU for a 8400 card. If you really want to play some games youll be better with a 9600 or 4650. at least.

If you go higher youll need a better PSU.

Mark updates the text version fairly often. The guy who did the image version made it based on Mark's original findings. I don't believe it's been updated for some time now.

Mind you, on their forum it clearly states that all the power ratings are not actual ratings Mark has measured himself, but rather ratings calculated on data given in reviews by tech sites, namely xbitlabs.com. Most are spot on, and some seem to have a minimal margin for error. Still, there remain a handful that seem as though they are still just a little ways off.

Your right Razb !

Exemple of my computer :

P5Q with E6850@3.6 (1.45vcore)

Idel ........................................... : 155 watts
LOAD 100% (ex. prime) ............ : 225 watts
GTA4 ( about 90% cpu + GPU ) . : 400 watts

We can say that my CPU use 70 more watts when 100% load is applyed and that my GPU seems to use 175 watts when on load. Its pretty near to what this chart is telling.

Just remember that the 2 most Energy eating parts are your CPU ( ++ if OCed ) and the GPU unless you have a 9600 and lower that are not power angry.
