I've decided. I'm going to upgrade when the new 939 dual layer chips come out.. with a new chip, and new pci express gpu x2 and a sli motherboard.

I'm just wondering if my Decent branded akasa 460w psu will be able to manage that with a couple of raptors and the rest of my hardware?

939 dual layer chips

I guess you are talking about the dual core cpus? They will need around 80-110W - not much more than a single core cpu.

But my advice: just try it when the time comes ;)

Which ever motherboard your looking at will have that info, just goto the manufacturers website and d/l the manuals and most should have the info included in them.

Lol thanks. Thats what I meant. I'm just having one of those days (glandular fever).

nrgy: Just outta Interest I'm having a look at my current 939 av8 deluxe manual and can't find any stuff like that :shrug:

Cheers

according to nvidia:

- 2xGeForce 6600 GT - 350W-420W, 12V - 20A
- 2xGeForce 6800 - 420W-480W, 12V - 25A
- 2xGeForce 6800 GT - 420W-480W, 12V - 25A
- 2xGeForce 6800 Ultra - 500W-550W, 12V - 30A

obviously it's a bit exaggerated since I know from my experience that a decent 420W PSU has no problems with managing 2x6800U together with A64 3000+, one 250GB HDD, 1GB RAM, DVD, SB Audigy etc.
however, i'm afraid that your 460W is not going to be enough for SLI and a few HDDs (how many exactly?) plus some other hardware...

Ok my rig atm has these drives.

raptor 36gb 10,000
wd 160gb 7, 200
lg dvd rw

I might get another 74gb raptor, as I find they are great for speeding up load times.

Thanks for those power ratings.. are those for when you actually have a pc running with them? Or do they take that much on their own. :D

Computers are meant to get smaller and cooler over time. Not bigger and hotter!

Isnt 600w a whole lotta power! Hopefully atis answer to sli will be cooler, use less power and will be smaller.
