Will a 450gts work in thsi system?

[zaknafiend]

I have a pc I built myself with an intel core 2 duo riding 2ghz, 2gb ddr2 and an nvidia 7900gt. I was thinking of buying an nvidia gts 450 but the problem is my PSU is an Antec Smartpower 450watt. please let me know if you think this psu could handle the load from this system with the gts 450 in it.
thanks.

Hello,

I don't know which Core 2 Duo you got, but if you have a very low end one, you might get a bottleneck with the GTS 450, especially if you buy a pre-overclocked one like the Asus GTS 450 TOP. Overclocking your CPU might prevent this problem though.

Also, your PSU seems a little bit on the low end for that card. I'd consider getting a 500-600 watts power supply just to be on the safe side.

Here's a list of power supplies from best to "worst" :

Seasonic SS-560KM
CORSAIR CMPSU-550VX
COOLER MASTER Silent Pro M600
OCZ Fatal1ty OCZ550FTY

Hope this helped,

thanks man, I know i should get another one, but my question was if it was Possible without hurting hardware to run it with this psu

A 350 watt powersupply should be able to handle a core 2 duo and a gts 450.

I would recomend overclocking your processor since it will be bottlenecking the card, but your power supply should be fine.

It depends on the age, but that's a very bad psu.
It's do-able, but I would highly recommend switching it out for another psu.

Then why would Nvidia recommend a PSU of 400w minimum to run this card ?
For example, the Asus gts 450 TOP can pull 125-150 watts, and that a Core 2 Duo pulls 65 watts minimum. That's 190 watts, without counting the HDDs and motherboard. I'm not saying that your 450 watts PSU wouldn't work, I'm just saying that running a PSU close to its max capacity is never good for its longevity, or its efficiency (your power bill). If you got a 500-600w PSU, you let yourself room for upgrades, if you decided to get a Core i5/i7 for example.

ok, guess i'll get it and if it overheats/shuts down on me i'll get a new one
will it hurt the hardware if it draws too much poser/cuts out, etc?
thanks for all the help

just on a side note - been researching my new build a lot lately and a lot of people suggest waiting with investing into GPUs atm anyway because of GTX 560 coming out in the beginning of the new year and even if you don't get it, it's possible if not probable that you will save yourself some cash if you wait a few weeks (some people suggested it should be out before 20th of Jan or so but that's speculations)
with this in mind may be investing into the PSU as suggested above will be a good option and then you can wait a bit and have both components upgraded for just a fraction more.

Plug ya system into this

Manufacturer recommendations are always conservative because a 400 watta PSU from a reputable supplier can be a safe buy whereas a 550 from a Kingwin / Rosewill would not.

bottom line is that it will work and your good to go.
period..

thanks man, that's what i was looking for. however if i can survive my 7900 atm i may go for another psu when the gtx560/gtx570 SE come(s) out. but there are some 450s on sale atm that are hard to refuse.
