Will 480W be enough?

[krazynutz]

Real quick. I have:

2.6Ghz overclocked to 3.25,
1GB of DDR, (2x512)
2 HDD's,
2 opticals,
7-in-1 floppy/flash,
SB Audigy,
5 case fans (4x80mm & 1x120mm) on a 4-dial fan controller.

With all of this, will a 480W power supply still be enough to handle either the 6800 or X800?

If you can run a 9800/5900 series card fine, then you'll be fine. And Nordicware mentioned that 430watt is more than enough.

right. I just wanted to make sure because of the peripherals involved. Thanks scott.

What you have to worry about is the stuff sharing the 12-volt rail, because that's what the 6800 will use.

The 5 fans would be on the 12v rail... but they don't draw too much. Your hard and optical drives might though, they're also on the 12v if I'm not mistaken... so you may be pushing it.

But that's a pretty beefy power supply, so you're probably OK. How much does it output on the 12v rail?

the 480 truepower has 22A on the +12V rail.

That's another reason why i like Enermax psu, the 550watt i currently have has 36A on the 12V rail.

The nice part is that even the Enermax 465watt has a decent 33A on the 12V rail.

Not enough juice. You need bigger 1000 watt Psu.

OK, I've never been Amp/Volt/Watt savvy, so will the 22A be enough for my setup? The only thing I might add to my system would be another HDD, giving me two 120GB in RAID, and an 80GB for backup purposes - but then, I can always put the 80GB in an external USB 2.0 case, right?

Well, I'm guessing Nvidia would have looked at the minimum output on the 12v rail they could expect from PSUs in this power range.

It'll probably work, but if you have instability it's a place to revisit.

You will be the first to know if it's not enough juice.

somehow, I find it hard to argue with that. Not really worried. I just picked up a 9800 pro that I'll probably use for the next year. My PSU (430W) just died so I ordered a 480W, not thinking that I should have spent the extra $15 and gotten at least a 530W. Ah well...
