can this PSU support 64-bit?

While it has a reputation as a good PSU, we have no idea what kind of system you're going to try using it in. 95% of the time you'll be fine using that PSU.

maybe.

I think you will find that it is the CPU and OS that support 64-bit computing. The PSU (looks fine) will support an ATX motherboard.

The reason I asked was because I read that 64-bit uses a lot more power than 32-bit.

The 420W PSU included in the X-QPack is a pretty good one, and will be plenty to power your system.

That PSU will run your system just fine. And where did you read that 64-bit uses "a lot more power"? That sounds like newspaper reporting. The same kind of "reporters" who tell people AMD chips are slow because they are clocked slower than Intel chips. Anyway, until you install a 64-bit OS and drivers, you'll be using your A64 in 32-bit mode.

The same people who tell us our cables need to be kept straight to ensure proper data flow. You see, it's all digital, all 1s and 0s, and the 0s being round & all have an easy time traveling through the cables, but those 1s often get stuck in the bends of the cables.

Please tell us whhere you got that from so someone who lives nearby can get over and smack them around.

Maybe this person was talking about 64-bit dual core processors?

WTF does a power supply have to do with 64bit support????

they have nothing to do with each other.

No, it's not. The first one died within hours of being turned on. I had to send the whole case back just to RMA the PSU. My replacement also died within hours. That's why I'm now looking for something else.

Maybe he was. I read his post early this morning when I first woke up, I really don't remember the details now.

I think what he was getting at (and what still makes sense to me) is that an Athlon 64 running together with Windows XP 64-bit will require more power than the same processor running with Windows XP 32-bit. That is a correct statement, isn't it?

While that does give the potential to use some elements of the CPU that wouldn't be use otherwise(extra registers for example) it's not something that would affect the power draw in any way that would possibly matter when picking a PSU.

Thank you for clearing that up, Sunner.

Ok, then no, that isn't a correct statement in any context... power consumption is based on die size, transistor count, and other silicon processes, it has nothing to do with physical bit-size. Incidentally, 64-bit dies are only slightly larger (1-2%) than their 32-bit counterparts, mainly because of the added registers... as Sunner has already stated.

But if this person were talking about A64 X2 dual core processors (or two physical cores together as one) then it's possible, in theory, to imagine that they would consume more power.

Although, on a side note, just now looking at new reviews, it seems AMD is turning in some remarkable power consumption number for their X2 processors. So it seems, at least for AMD dual core processors, the power supply requirement pronouncements were slightly exaggerated.

It sucks they include a really crappy PSU with it, be nice if they threw in a Sparkle or Fortron at least those you could trust.

Anyways the things that will draw power on your setup are follows;

1. Video Card
2. Motherboard/CPU
3. 10,000 RPM Hard drive

The Xclio is a great PSU from what I hear.

Actually it isn't only dependant upon that, but also upon the work the CPU is performing.
With clock gating the work being done can very much affect the power consumption, though I don't know if AMD uses clock gating for the A64 or if that's an Intel exclusive(well for the x86 world anyway, I have no idea POWER, MIPS, etc use it).
