GTX690 12v Rail Amps?

[TheLegendOfMart]

I've tried googling but its hard to get a consistent number.

I have a Corsair CX600M which has 46A on 12v rail. I have the chance of a super cheap GTX690, will my PSU be able to power it?

Looking at reviews they put total system power draw between 450w and 502w. That is going to vary according to the rest of the system though and doesn't include overclocking. Seeing as your psu only has 552w on the 12v rail and the fact that it has poor quality internals I personally wouldn't be running one off a CX600M.

How cheap is super cheap?

I say that because a 2gb (effective) card probably isn't a good buy.

 

[stooeh]

Nvidia's site has 650W as minimum and EVGA's site shows theirs needs 38A on the 12V so you might be okay. If that PSU really does have poor internals I wouldn't risk it.

^^^This

2gb really limits the cards.

 

[koooowweeee]

There 4gb cards. Still great cards as well

 

[keaneo]

no they are not 4gb cards technically

Not really, only 2gb is usable.

 

[Yaayuh!]

I wouldn't, unless you're playing at 1920x1080 and still willing to turn memory hog settings down/off.

4GB shared over both cores, so 2GB effective. Had one at launch, great card but wouldn't want one now

Thanks I won't risk it then.

Would have been £50, told him to flog it on ebay.

At that price I would have grabbed it too mess around with, I also think the psu would be fine, They're not that bad.

For £50 it's a no brainer in fairness. I'd take it even just to fool around with. Will still drive most games at 1080p ultra fairly well, SLI support dependent, which is a lot of performance for £50.

£50 is cheap... a 680 is probably more than that.

Up until recently I ran 2x 670s in SLI on an old 600W OCZ modXstream PSU for the best part of 2 years with no issues. Rest of spec as in my sig.

Yep. Recently sold a 680 for more than that.

Nope!
