GTX-285 Power supply requirements

Hello ppl

I was about to purchase a GTX 285 in the near future, but i do have a few things in mind, so if you'd be so kind as to help me....

1- My Current Powersupply is Cooler Master eXtreme Power 600W. It supplies 18A on the 12 v rail. If i go sli in the future, will i need to change powersupply ? If so, will anything less than 1k watts work or is that a must?

1A- Are tehre any links showing the power consumed by these cards?

2- I have two offers atm, one is the XFX GTx285 and an EVGA GTx285 (Both with standard clocks), so any suggestions regarding either? THe evga is arnd 22$ lesser.... Also note that my mobo is XFX 750i.

Thnx in advance

Usually you will see people get single railing, which can be "OK" but, if your going to get some top stuff/oc'ing/multitask mainly, look at split railing like 4+ rails of 18/20a+. That might look low to you but, in actuality, 18a's is alot but, not 2 12v rails on 600w of 18a for the whole computer.

GTX 285 - 750w corsair/ocz/pc power cooling - mainly high end gamers that like to kill there electricity get single railing or like to think they can get a much better oc with single rail. If you decide to sli later on, look in the 850w+ range.

Hmm, firstly, thanx to all who replied

@gkay09: Thanx for the psu calculator link Been trying to find something like that for quite some time now

@Fullmetall: I plan to sli later , as in about after a year or so... till then i hope the psu prices wud also come down,.. til then ill have my trusty ol 600w with me with the 285

@theAnimal: yep, im using this rig atm, but im getting another one just now, and ill swith the 600w psu to the new rig, and get a 400w for this one. Actually, im already over my budget, hence the swap. Im currently getting the following System:

Q6600
XFX 750i Sli mobo
2x Corsair XMS2 DDR800 2GB rams
And prolly an EVGA GTX285 (or maybe an xfx one.. havent decded yet, tho the xfx is more tempting than evga )

Will use the 600w with the gtx285, and get a new temp 400w one with the 7900GT.

As for the q6600, i know its getting obsolete, but i will oc, and think itll perform better than the q9400, which is over my budget.
Same with the 750i, cant spend more.. and i dont like intel chipsets

But recommendations are always welcome

Oh yeah, that too... im going for Viewsonic 20" va2102wb.... Res: 1680 x 1050

Coz 285 min res for best performance is 1600x1200 ii think. And 1280x1024 wud be a disgrace to such a card

I am running a gtx285 with a corsair 550 just fine.

nope, its actually this one:

There is another Viewsonic 22"in the same price, same res, but i dont like its looks

As for teh q8300 or q9300, they go over my budget, and besides, at 3.0g and a lil above, the q6600 shud beat em Phenoms arnt that future proof as the intel now a days imho

And as for chipsets, please suggest me intel chipsets comparative to nvidia's. Coz the G31 has got bad reviews, and so has P45 / G45.. i dont have the money to go for the X series

Q8X00 and Q9X00 are faster clock for clock than the Q6600.

May I make a suggestion?
At the resoloution given, a GTX260 would be a better bet than a GTX285, and you could put the money saved into a better PSU.

they both great with great warranties. Get whichever is cheaper. I you don't plan on going sli get the corsair 650 psu, if you do get the corsair 850.

Well here is another tough one: What should i go for from these mobo's:

XFX 750i SLI
ASUS P5QE
Asus P5Q Pro
MSI P54 Neo3

SLI might be an option, but its farr off, and almost negligible. Stability and OCing are important.

oh as for the psu, ive already got a Collermaster 600w, so ill use that for the 285. As for the 7900gt that i currently have, guess ill buy a 450w psu

I have this system: Cpu: I 720 Oc 3.6 Gb, MB Msi Platinum X58, SuperTalent DDR3-1600 6GB,.....a PSU : Thermaltake Toughpower 600W, with 4 rail of 18 A, end two six-pin PCI Express power connectors.
I want to buy the GTX 285 BFG OC2 video card, or a Evga SC gtx 285.
Please help me if you know, Wat is the thing with rails( PSU has a total 48 A, how this is calculated??? )end If a GTX 285 with a necessary of 40A/42A it wil work with my power supply.I don't have money for another PSU !
Thank you

I'll support what everyone else is saying and agree that 600W will be good for a single 285, I'm only using a 700W. However, if you ever intend on SLI, you'll have to go 850+ to run more than one 285. As far as the Q6600 goes, I say go for it. I bought mine a few months ago and couldn't be happier. OCing it at 3Ghz with no problems at all, on a 750i FTW mobo.

Nice Man!

Hope your happy!

Best of luck!
