How long will a 160PSU power a 300W graphics card? And if the PSU powered it before?
Ok last time I put a EVGA Nvidia 7300GT PCI-E on my PC with a 160W PSU, but every thing was running normal, the CPU. The PC did not slow down. The only thing that changed was when every time I turned on the PC, the PSU fan turned really fast and was kind of loud, but it only lasted for 5sec, and the PSU fan went back to normal like if it did not have the card on. I played some games on high settings, Doom 3, Halo 2, GTA San Andreas, and the PC ran like normal.The games ran smoothly. My CPU is a Pentium 4 HT @ 3.20GHz. If this power supply can power this card, and in the box of the graphics card it said for a 300W or greater PSU, AND IN THE USERS GUIDE minimum system requirements are -
Intel Pentium 4/AMD Athlon XP
Available 16 Channel PCI-E Slot
Windows 98SE/ME/NT/2000/XP
128MB RAM Recommended
and in the users guide it did not asked for a PSU. Out side the box has the same system requirements as the users guide but with the PSU requirement. I have Windows XP, 1Gb of ddr2 ram. My PC is a Dell optiplex GX280. AND NO I CAN'T BUY A NEW PSU!!! You know how Dell PSU are. And no I don't have this card on right now in my PC, I have a Radeon X300.

The psu will power it until it fries itself or something else to be honest. When you have a computer that is looking to draw more and more watts from a power supply that doesn't have those watts then you are taxing the PSU past 100% of its normal functionality and eventually it will die because it shouldn't be at 100% all of the time let alone past it's rated 100% load.
I highly recommend getting a new PSU, and since you can't get one now, save up for one. You can easily get a 450 watt psu for under $50 on Newegg or Tigerdirect.
I wouldn't risk losing some of your computer components to an overworked PSU.

The 450W powersupply is very almost good to your configuration... yet i choose you to decide for 550 or 550+ skill furnish becuz in case you completely throttle the skill of your processor and pics card and use all the USB ports availble on your motherboard then this is going to reason issues......
