i got a warning saying my system is underpowered for my new 6600GT card...how much should i get?

Also, which brands are good/cheap?
 
get a decen 500watt powersupply. make sure it has atleast 25 amps on the 12v rail. as far as a 6600gt goes, they take about 75 watts, so on agp thats why you need to plug them in, cause an agp slot can only supply 45 watts. brand wise, xfx and bfg make great cards. pick up an xfx for 150 AR from monarch and pm consumer9000 about his stasis thermal IceStorm, cause its the only FULL memory and core cooling aftermarket solution
 
are you sure you plugged in the power connector?

when i first got my 6600 gt i rushed to toss it in and boot up and completly forgot to plug in the power connector.

i got a warning message once i was in windows saying that your card is not receiving enough power and it has been underclocked to protect other hardware.... please check power connection or replace powersupply with a higher rated one...

anyways, i shut it down, plugged in the power cord and was good to go.
 
oh, you dont have the card yet... where did you get this warning? what are your other system specs?

i have the msi 6600gt, and i love it because of the vivo.
 
ohh, i think he meant powersupply brand. check out the forton blue storms, ocz, pc p&c, antec possibly, but NEVER NEVER go near a ultra powersupply. they = crap
 
The 6600 does not have an auxillary power requriement( assuming PCI-E). I good 400 watter or better is all you will need but you mine as well go the best you can afford so your future proof

I doubt a 6600 GT takes 75 watts, seen as a 6800 GT only takes 55 watts.
 
yea, 6800 takes 55, cause they are based on agp slots. pci-e slots can put out more voltage, and thats why when they do bridges from pci-e to agp they need the dongle, and if 6800 the use 55 watts, they why do they need a power dongle connected to them?

Maybe for more stable power? You could ask the same question as to why a 6800 Ultra needs TWO molex conenctions when it only uses 72 watts.
 
thx for ur replies. my specs are:

asus a8n7x deluxe
512 kingmax pc...3500 i think (been a while)
2 120 gb maxtor drives
6600gt tdh
enermax 350 psu (its a few years old so i dunno if it is new enough to support card or not)

not many peripherirals...just a ps2 gamepad and printer.

um, i fergot to hook up the power cord or i elected not to cus it said it was optional...but its in an agp slot so sounds like thats what i need to try out first. thx.
 
well ive hooked up the power cord and now my system seems to be locking up on me. ive tried rebooting 3 times and all times it has locked up...is there a specific power cord off the psu i should be using? or is the 350 enermax just not enough juice?
 
do you have anything on that line past the card itself. id try removing that and putting it on another string of power dongles. if that doesnt work, is psu upgrade time.
 
it sounds like your power supply just isnt getting it enough juice. do you have a friend with a higher end psu you could try?

otherwise i would recomend going out and buying a beefier PSU
 
yea, the cord is also hooked up to the fan...ill try taking the fan out the loop and see what happens. if not, it might be time to go to the computer store.
 
i had some 'thodes hooked up on mine, and it made my 3.3v rail droop to like 3.14v. so i took it off, put it on the other string, and it was fine.
 
i just took took the fans off and had direct power to my psu and hooked the 4 fans up ina daisy and it works now...however i have the feeling im riding the bleeding edge of my psu but my puter hasnt frozen for hours thru heavy gaming.
 
I'm running a 6600GT in a shuttle with a 220w power supply. You should be fine. You can run "ASUS Probe" to check your voltages and see if everything is OK. It should be on your Motherboard driver CD or you can download it from ASUS.

well let's see. 6800gt/ultra is spec'ed by nvidia at 110/135w iirc (sorry, i would provide a link, but i can't find one)

if the 6800gt is indeed 55w, the 6800nu is actually giving the system power :D
i'd say that the 6600gt draws ~50-60w from that graph.
 
i thoguht i remembered seeing somewhere they needed the extra power dongle cause the agp slot could only supply x-number of watts, and cause its pci-e native, which can give x number of watts, it had to get it from somewhere. i think pci-e might be a 75w card slot, and thats where i got my 75 from.

The latest AGP specification calls for a maximum of around 45W of power to be delivered via the AGP slot itself, while a PCI Express x16 slot can supply up to 75W. Because of the reduction in power that can be delivered via the slot interface, the GeForce 6600GT AGP requires the use of a 4-pin molex connector on the board itself to deliver extra power to the GPU. You may remember that the PCI Express version of the 6600GT does not require a separate power connector.

i have whats in my sistem and my card doesn't require a line from the psu, it gets it all from the pci-e connector :) /joy. Anyways I'm running a 520 watt psu from vantec and it has been complete sex since i've gotten it.
