Can my PSU Chew it???

Pls note that the PSU does' have the ext. connector

I would say that would be pushing it. If it were my computer, I would look for a more powerful PSU. I would also opt for something similar from the ATI 5xxx series which would use less power. The other thing you will want to check is, will it physically fit in that case?? here are some alternatives

Yes, its definitely pushing it and if you did get away with it I'd say you'd need a low power edition I.E Galaxys 9800GT LPE

It's always better to have too much power than not enough, upgrade to a 450~550w Name brand PSU with good railings

The Dell 375W PSU I know of has that 6pin connector. Are you sure it isn't just tucked away somewhere? It also has 30A available on the 12V rail, so you are good with the 9800.

Why buy the 9800GT? There are better cards out there unless your getting way cheap.

Guyz i was getting it used but few of my friends dishonored it so now i am inclined towards a brand new card...

--can u please suggest the best bang for buck Nvedia or ATI (which can also run best on my 375 watts PSU "30A 12v")--

Secondly guyz at my locale it is difficult to find all the Brands (eg. Galaxy) ... the famous ones like "EVGA, XFX, HIS, Palit, ASUS, Inno (crap   )" etc are available... i guess low power edition is difficult to find...

If u can spare a little time and just to be precise these are the list of the GPUs brands and their prices available here.. please select one as per best price, performance and most important my PSU support  :

Thanks for all ur help and time guyz.. i am waiting for ur intelligent replies...  

Rather then list every card out there, please list what cards are available to you. I'm not sure if you can run a 5850 or GTX460, but the 5770 is certainly fine on your PSU. Did you find the 6pin plug?

Am surprised with the 30A on the 12V rail rating on a <400W PSU (that too from Dell).. If you can, get a quality 500+ W PSU which will last you through many future builds and/or upgrades comfortably.. If you can access newegg, then check out the combo deals (PSU + GPU) on offer..

It can just barely do it. (12* 30 = 360) I don't remember who makes it, but it can do the 360W in actual output. Do a search for it, its a pretty tough unit. Seasonic? Delta? Something like that. It should allow him to use a 5770 or GTS250.

Guyz my mind focuses on XFX 5670 512MB DDR5. It's official requirement is 400Watts. Looks tough too.. cheaper than 9800Gt benches are better too (in RTS)... i think it can sure run fine... what do u say guyZ..... hmmm?

Max power consumption is about 50% lower than a 9800GT, definitely not problem for the Dell 375w

ThatZ my point  
so now i am going for it... any last words...?

5750 is better? Not much more expensive last I looked....

It is much better but it's official requirement is 450W... so i think 5670 is better for now... besides this system has a Pentium D 930 3.0Ghz(4MB/800FSB)   .... So what is the need of GPU which at the end bottleneck and produces the same output... therefore 5670 is the way to go 4 now on this built..  
any more suggestions?

You seem to be really stuck on " official requirements ", under full load the 5750 uses slightly less power than the 5670.
