Good Morning All,

I'm having trouble trying to determine if my new 9600GT will overload the existing 300W PSU. The existing card is an Nvidia 6600, and the 12v rail of the PSU is rated at 19A

Sorry if the question is a bit basic but I have searched myself to a standstill.

That card 100% will not work with that powersupply. You need a 500w or greater powersupply with 26 amps on the 12volt rail. Good power supply brands are antec , thermaltake , and corsair. It should cost you a minimum of 60$. Don't run the 9600 till you have one.

Thanks Emo,

I like a good, unequivocal reply.

Rob.

 

[emosun]

No problem

Hi Again,

just for my curiosity, what would be the current draw/power consumption of the 6600, please?

Rob.

 

[emosun]

Maybe takes away 100 to 130 watts of what your current psu is. However a 9600 can easily take away 200 to 300 watts.

Rob.

does it have a 6 pin plug? If so, minimum 15-20 amps. If not, maybe 10-12?

Thanks Emosun,

don't you sleep?:smile:

its only 8:30 pm I don't have to yet , lol

 

[Crossy]

Thanks for the replies. Is it too simple for the manufacturers/suppliers to provide these figures for their products?

It's how nvidia and ATI make money. They make general suggestions so that if something fails, the card and/or PSU go out with a bang, and if you try to rma, they can say it's your own fault for an improper PSU and make you pay out ofpocket for new ones.

 

[emosun]

They also recommend low power psu's so it seems more possible to upgrade any pc.

The trick I fell for is that my HP Pavillion documentation has no mention anywhere of the PSU rating and I could only find the data by opening the PC up and reading the side of the PSU. I actually should have done that before purchasing the 9600, that way I would have purchased a new PSU at the same time. I think I'll go for something around 600W, just to be sure.

Thanks for all your help folks.

Rob.

I've researched my choice down to either the Corsair HX620 or TX650, to give a bit of headroom and scope for future upgrades.

The main difference I can see is that the HX has 3 x 18A, 12v rails where the TX has a single 52A 12v rail. I can see advantages for each design, is there a show stopper for either configuration, please?

Rob.

 

[emosun]

You'll want the tx as 18 amps is not enough for a pci-e setup. 52 on a single rail is the better choice.

 

[Crossy]

Thanks Emosun,

I picked up the TX for AUD180. It's a long weekend in Australia this weekend (Queen's Birthday you see), so guess what I'll be doing this weekend.

Just for interest sake, the 9600GT came with a combiner for the 12v rail so I could have (apparently) combined 2 of the 18A feeds. Would this have been acceptable?

Rob.

 

[emosun]

No just stick with the tx.

 

[Crossy]

Hi Emosun,

I shall be sticking with the TX, I was just asking a hypothetical question.

Rob.

 

[Crossy]

Well, time for a progress report I guess. I have installed the TX650 and the 9600 GT, and all worked first time. Downloaded the latest driver (175.16), but I can't actually discern a difference from the old 6600. Have I missed something?

Rob.

 

[emosun]

Well what games are you playing and the rest of your pc specs too. If its not showing any difference then theres something wrong.
