Nvidia Graphics card question
show user profile  mike_renouf
A mate of mine is offering to sell a GTX470 (I think its a vanilla one, not some special over-clocked version) for about £60 (English money). This seems like a decent price considering that I'm currently running a GT545 which has very few CUDA cores for max, and is pretty underpowered for the one or two games that I play occasionally.

The main question is, that the spec of my HP workstation:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&docname=c02902545

seems to indicate that it has a power supply of 460Watts, but the GTX470 requires 550Watts and additional two 6pin connectors.

Can someone brainy (e.g. Stabby) confirm if I'll be able to run the card with my machine as-is? Will I need a new power supply? Bearing in mind that my PC is not overclocked, the card won't be overclocked, and I shan't be doing anything like that for the foreseable future.

Many thanks,
Mike

460w noname PSU doesn't look too good, it would have a weak 12v rail to begin with and throw in some capacitor degradation you'll lose another ~20% of the rated power. You could still try it, most graphics cards come with a molex->6pin converter or two and plugging it in wouldn't do any harm, its just very probable that it wont run though.

Best go shopping for a new psu, look for a big 12v rail and low ripple (keeps rest of the computer ticking longer). I'm not very up to date with 500w'ish PSU's but i can recommend corsair tx850, very impressive under an oscilloscope (doesn't necessarily scale to its lower rated brethren)

Thanks Stabby - as usual, you came up with the goods :)

Liondebt - I'll probably keep the existing card in place because it has some CUDA cores which can also be used in iray. Plus, its got a standard HDMI port (which I kinda need), whereas the newer card only has a mini one. Better luck next time ;)

Dang :) - no worries bud! Looks like I'll have to dust off the ol' credit card and purchase that GTX 660 Ti

Doh. stupid cheap powersupply only has one 6pin connector and the GTX card needs two. Looks like I'll have to save up a few more pennies for the corsair.
