Hello,
i have a core 2 duo e 84oo processor in my computer which takes about 65 w (checked in wikipedia) currently there is a power supply of 305 w installed in my computer. i read that gtx 550 ti needs about 110 w.would my current power supply be enough?a 400 w power supply has been recommended for this card.for the record i am successfully runing an hd 6570 card which also need 400 w power supply (read on amd.com) i am gonna write down the model of power supply actually i have a dell optiplex 755 so its a dell power supply model no.l305p-01 dell p/n:nh493

450 to 500w is a recommended not a requirement in some cases depending on how power efficient the card is and what quality PSU you have, will determine if it will work. But in more cases than not its better to have at-least the minimum.

I want to say yes, but you might end up getting and and not being able to use it until you get a new psu.

Ill do some more research what gpu is your 6570 is it an oem or a 1gb or 2gb give me all details you can about it

Accoarding to this the 550 ti is going to use more than 2x the power sooo I think it might be a no go on the buy until you get a new psu. If it was somewhat close like within 10-20% id say maybe but the difference is too much here.

by yours you mean the 6570 even if they are a little different yours is using maybe a little bit less, this is just a possibility but they should be just about the same.

ok what if i buy the 550 ti and try to run it on my current pc? is there any risk involved? i mean i may buy the card and if it does not work i may use it latter when i am able to get a new power supply.i can use my 6570 till then but i want to be sure that testting the card on my current system wont do any permanent damage.i hope u get my point
