I have a 500 watt psu, & it ran 2 7900gt's in sli, 3 hdd, 2 dvd drives, 2 cathode lights, 5 80mm fans & several usb devices. It was never stressed. I now have a 8800gts & it does fine with it. I think 650 should last you quite some time.

ConstanceJill;3682349If you have a good brand PSU, you'll never need more than 400 Watts unless you have let's say, 5 HDDs hard working at the same time ...

A lot of high end systems won't even function with a PSU like that. If memory serves, some of the best Intel processors use 150W by themselves. Add a couple of high-end graphics cards to that and the PSU will be screaming before you've even done motherboard, memory and drives.

Nah ... that's what they want you to believe.

If you can read french (or are not afraid of automatic translations), read that : Puissance PC - Consommation des PC: le grand test

That's what I thought too, which was why I got so much [It's a big upgrade from my 430 Antec].

Strangely enough Jill, I wasn't talking about a 3500+ with a mid-range graphics card...the figures they give are, like everything else, theoretical maximums. If you're using a QX6800, it's unlikely to ever hit 150W, but it's possible.

As the new hardware components use less and less power 1k PSU will never be a standard

Hmm no, you didn't understand. There are 3 test machines, the "top" one being based on an Athlon 64 X2 4400+ and a 8800GTS ... and they give both the theorical power consumption (given by some dedicated website) and the one they measured ... even after overclocking their "gamer" machine, while playing a 3D game and copying files from a DVD, the maximum external charge they found was 407 Watts. That's still quite far from 650...

Given that I haven't spoken, written or read french for 2 1/2 years and I was crap at it then, that's as good as you're going to get. :p

Wattage isn't as useful an indicator of how powerful your PSU is as opposed to how many amps it can deliver on each of its rails.

Sam is right, current is more indicative of a PSU's capabilities. I am confused about something however. I have a 580W PSU with (2) 12V rails totaling 38A. I have 2 WD Raptors and 2 Plextor opticals, as well as 6 case fans (4 of which are LED) on top of my specs listed at the bottom. I would like to add a second identical VGA to my setup in the very near future. I have been told by various members in this forum that my PSU just isn't going to cut it (if I add a second graphics card). This was confirmed by an online wattage calculator (amp ratings weren't included in the calculator). Any thoughts?
