Need GPU Advice

The rig I built back in 2008 died on me a few days ago. I needed a emergency computer so I bought a Dell Inspiron (oh man!). It is a 3650 i3 with 8gigs of RAM and a 1 Terabyte hard-drive. It has one PCIex16 slot on the board. I want to put my PNY GT 740 in this machine because the on-board graphics are horrible.

Problem is, I doubt the psu is very powerful. GPU makers tend to pad the specifications and recommend more power then their cards actually need. I believe the psu in this machine is a 240w model and proprietary. The computer has a DVD/CD/RW drive, mouse, keyboard, four 2.0 USBs and two 3.0 USBs. Integrated Sound card, etc.

The PNY GT 740 is powered by the PCI slot, no power connector and it is the 2GB DDR3 version.

Think the PSU will handle it?

Thanks.

My card doesn't have the 6-pin connector, it is powered by the PCI slot itself. As I mentioned in my OP GPU manufacturers often pad the specs due to so many different configurations. I doubt my total system power + the GT 740 would go over 200watts but I am not 100% sure. I'm looking for someone who has experience in this area and has built a lot of machines. Thank you for the reply.
 
The PSU has enough power, the question is whether Dell limited the amount of power available to the graphics card on the motherboard. On my optiplex servers, for example, the PCIe slots will only output 25W. If there's a limit it should be printed in text next to the pcie slot, otherwise you'll probably be fine.
 


So you have a processor that consumes almost double the power, a gpu that consumes more than double the power, and you want to compare the two systems?

Is it a physical limit that cannot be changed or something I can change through the system BIOS?
