Buying a used gtx 480....

[amuffin]

Hey guys, I found an ad on craigslist and I have already emailed the guy about the purchase. Its a evga gtx 480 for 200 dollars and was used in his gtx 580 sli rig as a dedicated physx card. Can someone list the amperages in order to power this card? Btw this is for a second rig that has a rocket fish 700w psu in it with: http://www.hardwaresecrets.com/article/Rocketfish-700-W-Power-Supply-Review/556/6 these amperages. Im not sure if they will power the 480, or im just too lazy to search up the amps needed to power the card....or I can buy another power supply. So this is for my second rig that has an: i5-2500k, gigabyte z68x-ud3h, 16gb ram, 1 250gb hdd, 3 fans, a cd drive. Would the 480 hog too much of the power so the system won't boot? Thank you for reading my post.

Should be fine as long you don't do some heavy overclocking. It'd be cutting it close though.

Wait whats the amperage for the 480? The rocketfish psu has 18amps for 12v rail.

[/strike]@amuffin that psu is ok for gtx 480 what is bad in this psu amperages is enough![strike]
ahhh! sorry didn't see the AMP 480 requires 42amp on a +12v rail

@amuffin that psu is ok for gtx 480 what is bad in this psu amperages is enough!

Yeah well its an average psu, but i got it for free, so im not complaining!

It is a little over 20 amps to run the card max full load. Rockfish is horrible when it comes to quality.

$200 is too much for a used GTX 480.

Some say it's comparable to a 570, maybe, maybe not. Power hungry, hot, noisy and how's that warranty?
Caveat Emptor.

Some math
Rocketfish has 509W combined on 12V rails. This equals 509/12 = 42.4 A on 12V rail combined.
509/700*100 = 72.7 % of total wattage comes from 12V rails. That's awfully low when good power supplies can produce more than 90% of their total wattage on 12V rails.
I wouldn't recommend using 480 on that PSU.

 

[amuffin]

well is it worth running it on this psu? I guess we will have to find out.

 

[amuffin]

What if I get an antec high current gamer 620w? I am sure it has enough, as it can power a gtx 580.

 

[xtreme5]

of course 620w is enough.

that psu is absolute crap and I highly doubt it delivers the specs it promises, its going to be an absolute gamble with a gtx 480 running in your system imo Id get a new reliable unit before proceeding with the gpu upgrade... the antec 620w unit would be a much better choice

 

[jjb8675309]

Rocketfish is absolute scrap metal I would not run the risk of ruining/degrading components

AW THE GUY TOOK HIS ADD OFF! Oh well :/
