Hi everyone, i have been doing much research but have decided to register here and ask the advice of you guys since most of you seem to know whats what with PSU's.

Here is the PSU i am currently using.

I am not sure if this is enough for me, here are my system specs.

Intel core duo 6600 overclocked to 3.2 GHZ
Ati X1950 XTX Graphics card
Asus P5n32 premium motherboard
Creative X-fi Xtreme music
Western digital Caviar 400Gb HD
2x OCZ Platinum SLI ready PC-7200 900MHZ 1GB modules

I think that about covers it. So as my system specs stand do you think this PSU is enough? I just bought a hiper power 580 watts Type-R from ebuyer but cancelled as i done more research and discovered this was not compatible with my CPU?? I am still not too convinced.

Anyway, i was also considering upgrading my pc to a DX10 card when it comes out and lowers in price and perhaps another HD of the same type for a raid setup in the near future so can anyone recommend a psu that would be ample for my requirements and is compatible with all my parts?
I would be very grateful for all your help as i am really getting more confused by the minute reading up on all this over the internet.

Many, many thanks in advance.

430 watts, probably not enough

go for about 550 for this setup.

You need 23 amps on the 12v rails plus 2-4 for safety.
Your power supply has 40 amps on the 12v rails, so you have plenty of power.
I find it kind of stange that a 430w PSU has 40 amps on the 12v rails.
Please look on the box for the maximum power on the 12v rails and report it back to us.
Here is a list of good power supplies:

There's no way this unit will deliver 20 amps to each of its rails simultaneously unless the 430 watt rating is extremely conservative. Probably closer to 30A combined. To the OP, you will be fine with this PS up till you jump to a DX-10 card. At that point, it still might handle the load but I'd go with more headroom at that point.

First of all thanks very much for your help guys, i was really concerned about this and i am glad i am getting some help. I am looking through the manual at the moment and i cant seem to find the maximum power to the +12v rails. there seems to be a lot of info there but i just cant seem to make anything out of it. So is it recommended that i change psu's then? I really don't want to damage the components of my new pc.

Thanks very much again for your time and help.

Can i just ask if this psu would be recommended or would i be better spending £100 on another psu?

How is the Hiper Type R not compatible with an Intel Core 2 Duo CPU ?

Ein Bier Bitte....Ok that's the limit of my German - but it has served me well these many years.

I would suggest that you visit the nVidia website to find their recommended PSUs for the 8800 series solution you are looking for - this is a good place to start.

You seem to be interested in modular cables - of which I have no experience. From my understanding, they are nice to keep your case as clean as possible, but you spend a bit of a premium for this flexibility.

If a traditional PSU is an option, I would suggest the Fortron products - as they have served me very well in the past. The 700W GLN product will support 2-8800GTX in SLI. There are also many other top notch PSUs. Try to pick one from the nVidia site, or the PSU 101 guide on this forum.

Good luck.
