More bad news for PS3 launch?

I have said for a while now until I see the units in the chain I will not believe sony has solved production problems. I don't think it is a stretch to think sony will have production problems for atleast the next 4-6 months.
 
Ok let me see if I can remeber from High School Physics, (this is from '85 so I will probably be wrong)


P=IxR

That is Power in watts (P) = Current in amps (I) times Resistance in Ohms (R)


So we aleady know the current of 3.2a but we need to get that Voltage into something we can plug into the equation.


So let's cheat & use this Ohm's Law calculator which is about 38 W


So, back in my NuclearNavy days (get it...NucNav) we were always taught, Power is easy as PIE, P (Power)= I (Current) multiplied by E (Voltage)
 
Guess nobody here has heard of power supply efficiency...

Also, the maximum is going to be everything maxed out + USB powering things, all the memory slots filled etc...

It's like CPUs "max power" ratings, they are never achieved in practice. The only way you can get anywhere near it is to run a specially written program called a power virus.

The PSU is probably rated above this for safety.


BTW the only official power rating I've seen for Cell is 110W at 3.2Ghz / 1.1v (8 SPEs).
The PS3 probably runs the Cell at a lower voltage to save power.
 
P=U*I doesnt hold true if you have inductors or capacitors. In terms of PSUs, the wattage is way lower than U*I, typically something like half of it, and that doesnt even touch efficiency. looking at what the PSU can output would be far more interesting.
 
80,000 units are what we can call a paper launch...

Right, and that's pathetic. This is not a defensible point. 80K for launch is inherently pathetic regardless of mitigating factors, counterpoints and the like.

Some may even call it a launch disaester. But given that it took the Japanese retailers minutes to clear out their pre-orders, Sony should be fine as long as their production continues to go up. Wii will sell to its Nintendo's user base initially regardless of whether PS3 has supply or not. What is Xbox 360's Japanese sales trend in comparison ?

What's more tricky for Sony would be US launch.

On the 80k thing... Who would have bet that MS may sell more 360's in Japan in November-December than Sony would PS3's? Meaningless point, but one of those ironies of fate that make you shake your head. Of course if Sony offered enough units Sony could outsell total 360 sales this gen in Japan in the same period if supply was there ;)
 
What are the expected shipping numbers for other regions :?:

Yes... that is true. For those curious... VA rating includes "real" power and "imaginary" power. The latter being "phase" shifted power considering the caps and inds. And... that's where efficiency comes in. Ideally you have caps and inds cancelling out in the analysis. ...Anyways....memories of that power systems class.... head ache.

(btw, P=V*I=I*I*R for real power)

That's only true if the phase of the current equals the phase of the Voltage. If you power on a device with condensators the phase will not be equal. Theoretical you can run a current through a condensator without any power usage (practical there wil be some losses).

Huh? MS is still selling ~2000 Units per month, so how should they achieve that?

Edit: It's per week, ok ;)

360 is dead in Japan and will be so most likely for ever till the end of time. Sure we might see some spikes with the BD and LO, maybe even up to the 100,000 units range and if Sony is really struggling with producing PS3 units then we might actually experience some weeks were the 360 might sell more than PS3, but that should be concidered as an anomaly in the universe and exception to the laws of nature...
 
So ? The purchaser has to make a decision then. People who import/ebay for a PS3 at this stage already know they will have to pay a premium regardless.

So?... What the hell is that? You act like you have some unholy reason to hate this question

Of course the buyer would like to know whether the 350 power converter is enough or does he have to buy the bigger one. And I didn't say anything about "at this stage", there are more reasons to import than just to get one's hand on the machine earlier, like for example the preference to watch US and Japanese Blu-Ray movies, that's not time related

It does not mean that the OP is accurate w.r.t. PS3's 380W usage (or Xbox 360's 500+W usage) during daily use. It also does not mean PS3 runs hot :|

Why are you telling me this? I didn't say it would. I was asking about the power usage so I could tell people how big power converter they will have to buy if they choose to import PS3. I certainly didn't say anything about PS3 running hot.

Ah I see. After reading this thread, I would get the 350W converter but that's just me.

I was answering to the thread. The OP includes a link that implies PS3 will run hot. This is despite all hands-on account that PS3 runs cool.
 
Sony Misses Japan PS3 Shipment Target
A further 20 % reduction in Japan, from 100,000 to 80,000. Will the U.S. follow?

Supposedly PS3's Taiwan & HK have been announced by Sony. Some are suggesting the missing 20k units could be going to these two locations.
Launch date: 17th November

Price:

Hong Kong 60G - HKD$3,780 (US$486)
Hong Kong 20G - HKD$3,180 (US$409)

HK linky

Taiwan 60G - NTD$17,980 (US$542)
Taiwan 20G - NTD$14,980 (US$451)

TW linky

P=IxR

That is Power in watts (P) = Current in amps (I) times Resistance in Ohms (R)

Except that formula is only true for DC Current.

With AC current assuming a sine wave the equation is P = Pi/4 IR
 
So uhm what does that actually mean in terms of units in Japan? They get 80k at launch, then what? no more until when? Those 80k units will be sold out before you can say Yen, so when is Sony going to send more?

Not that they're worrying, even if they send and sell around 2000 a week - which would be ridiculous - they'd be outselling the 360 by almost double in that territory..

Still, didn't we expect things to get better in time, production-wise? When is Sony going to ramp up production? At this rate, the "2M units ready" figure for Europe seems very unrealistic.

Next ship from mainland China presumably?
I think a large part of the decision that gave the Japanese only 80k (100k at first) units, and 400k to the US is that it takes much longer to move products across the pacific ocean. If it takes a couple of days to get a load of product from the factory, you can obviously react much faster to market needs, so there's not as much need to have huge amounts of stock sitting in the country "just in case".

I.e. resupplies to Japan will arrive in a steady trickle, and I expect that to happen at around the same rate as to the US. It was much more important to have sufficient stock in the US on day one, for more than just one reason (competition, logistics).
