9800GT on 450W, 12V@23A

[Guest]

Hi people. I would like to ask if 9800GT asus with 1GB will run on a mtech power supply with one 12V rail at 23A. Thanks for your help.
My specs are AMD x2 5400+, 2GB, 320GB hd
I am worried about the amps, should i buy better psu?

What brand is your psu? I once ran my 9800gt off a A-power 480w pos that only had 18a on a single rail. The psu later degraded but replaced it long before it would have failed.

Mtech is the brand, its not very popular. But outside it looks like a fortron psu, but its not

He has 23 amps at 12V, so he will be fine...
9800GT is not power hungry card.

Yeah, but in all reviews they say that is minimum requiring 26A, recommended 30A...
And i am newbie, so i get a little confused

There are 2 different versions of the 9800GT. The newer version uses much less power and doesn't have a 6-pin power connector. Your PSU can definitely handle that card fine. It can probably handle the other as well but if you want to be safe just look for one that doesn't have the power connector.
You also may want to consider the HD5670 instead. Similar performance and price but it is DX11 compatible, supports 3 monitors and has more current video/audio playback features.

Thanks for the ATI advice, but i will stick with nvidia for now. http://pic.bg/komponenti/40932/640

That card is one of the older ones with the power connector but the site does have some of the newer version(as well as an HD5670 that is cheaper than the 9800GTs )

Yeah, they are underclocked by about 10% if I recall. However they can supposedly easily be put back up to and past the old default speeds with an OC.

Thanks for the replys. I was about to go for 9600GT or GT240 just for those amps.

So, finally, can I run this card on a single 12V rail @ 23A or I can't?

Sure. Absolutely.

 

[Guest]

Ok dudes, thx for your time and for the help

To OP: You have more than enough amps on 12v rail to run 9800GT...

from my own experience of running the 9800GT & 125w CPU on a 18a single rail PSU, he won't be "border lining". In fact, i find your experience level with PSU information...lacking of knowledge.

I speak only of my own experiences. I do not work for a computer store so what you say is well within reason.
Don't let me confuse us. I'm still gearing for the future so looking at the past I could have my wires crossed.

If it ain't needing over 36a I probably have no business posting about it.
I had to go through the whole "Why won't my 8800GT run on my Bestec 300 watt PSU" question about 3 years ago, so I'd say I have a little knowledge on it.
