How much watts does the Nvidia GeForce 7300GT use?

Question

How many watts does this card use? I know in the box it says for a minimum of 300W, but I know this card does not use this much wattage. Its a EVGA GeForce 7300GT 128Mb. If I put this in my old PC, will my PSU handle this? My PSU is a 160W PSU. My CPU only uses 84W and its a Pentium 4 HT. But anything else connected to my PSU will be a HDD and a optical drive. No I can't get a new PSU because its a SFF PC and there is no PSU that will fit my case, and I got a Dell PC and yall know how Dell PSU are. I already put this card in this PC before and everything worked ok but the only difference was when I turned on my PC the CPU fan spin really fast for 3 seconds and went back to normal. And when is was using the card in full load the PC was running normal to. Thanks.

According to the power supply calculator, you will be using 188w. Your power supply is only 160w. I highly recommend that you don't put the card in (unless you want to risk your PC blowing up).

hi brett
                  the power supply calculators mentioned in the other answers are good ways of indicating the amount of power you need however what you have forgot to take into consideration is the ampage...this is as important as the wattage and if you dont have enough amps on the +12v rail(s) then either your card wont start or it will throttle back the core and memory clock speeds to make up for the shortfall
                  however you can buy small form factor power supplies that will fit in your case,for example the "Logisys SFX / Micro-ATX 350W Computer Power Supply"( http://www.xoxide.com/arrow-matx-300w-psu.html ) ...this is designed for small form factor cases like yours and should fit ok in your case,,,dont listen to all the dell "only use our stuff" nonsense....they say that so you will pay the massively inflated prices they charge,,,this psu for $29 will cost you around $90 if bought directly from dell
                    also check out the Extra Value Micro ATX 300W PSU - 20+4pin, 1x SATA ( http://www.ebuyer.com/product/125004 ) ..this is only Â£16 and with 300watts of rated power its more than enough for the EVGA GeForce 7300GT and with 14A on the +12v rail this is ok aswell
                     however for a real quality sff psu check out the "Be Quiet TFX 300W MicroATX PSU - WxHxD 85x70x175mm"( http://www.ebuyer.com/product/173802 ) and at just over Â£50 this is more expensive than other similar psu,s and with 3 x molex and even 2 x sata connectors this is the one i would buy if i was in the market for a sff psu
                    the cpu fan spinning fast could be a thousand and one things however i understand your concern,,and a psu uses alot of power during boot-up....thats why you shouldnt keep using the 160watt psu,,,,,go with the Be Quiet TFX 300W ...this oozes quality and look the biz aswell
                   i hope this helps,any problems let me know
                               good luck brett   !
