Whether to upgrade PSU or not

[scoot15638]

Hello,
Im sorta revamping a GM5478 Gateway, new graphics card, new motherboard, and new operating system, I am running a 400watt power supply, i am trying to decide which graphics card i should buy
I know the 128 bit GTS 450's have no problem with a 400 watt power supply, this is the one im looking at

But, i do want to play some newer video games that are coming out on the market and i know this card will do alot better job in the long run.

My question is can i still run that card with my current 400 watt power supply or should i just not bother and go with the cheaper card? Or should i upgrade both my PSU, and graphics card. OR does anyone have a suggestion for a graphics card that is about the same as both of those for the price range......Thanks!


my rig is 2.4ghz quadcore, 500gb hdd, 4gb ram, intel micro atx motherboard.

For some reason i cannot post a picture of the power supply picture, but i am quoting someone
"it does have decent 12V output. It can do 30 amps combined across the two 12v outputs"
it says do not exceed 30 Amps

as your 400 watt stock gateway psu is of unknown origin and supply, i would absolutely change it out first. here's a good choice. http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093

then go ahead and splurge on the 460.

So you know; typically a Delta Electronics DPS-400

I don't have any personal experience with that particular power supply. But it seems to me that there is a concern that it may be a bit lacking for the 450, and that it may lacking even more for the 460..

It's all your call, but my choice would be to drop a known and reputable aftermarket supply of sufficient power in the unit before taking a risk on frying an expensive GPU.

another slightly cheaper alternative;

Will that work for my GM5478 case though? I mean hell, thats pretty cheap 49.99 after mail in rebate, i would perfectly fine in buying now. but i dunno if there would be any cheaper PSU's right now or anything, PSU's are uncharted territory for me.

You really don't want anything "cheaper".
