MSI GTX780 Lightning due 07/08/13

Yeah, its pretty simple and frightening, If you start off with a big power supply you don't generate the voltage you intend to use If its very low, like CPU/GPU because a. you would require massive cables (even a stock CPU) pulls 50~100 Amps
b. you would have a massive problem with voltage drop/variations due to the conductor varying resistance due to the heating effect of the current.

So we feed the cards 12volts and it's locally regulated down to the core voltage, we can even send a sample of that core voltage back to those regulators so they can constantly vary their output so the core sees a nice constant voltage.

So once at that core that voltage is low but the current is massive.

I hate you :p

My head started to implode after all the reading yesterday,

completely forgot about dc/dc converters and the likes :D

This answers my above post, well explained :)

You fancy trying to teach my 2nd year apprentice something? The lad still can't get his head around class 1 & 2 differences, god help me when it comes to helping him through atex :mad:

:D Double insulated, tell him it's like it has it's own independent electrical generator, separate to all the rest of the worlds electricity... so basically he would need to touch it in 2 places to complete the circuit and get a shock.

Reminds me of my first encounter with 240v, as a 6 year old I wired up a Scalextric transformer plug and thought I best test my handy work before I put the top on the plug.....I learnt lots about electricity that day as i pushed that plug in with the palm of my hand :eek: :D
 
Haha :D

I've lost track of the amount of times he's had a double insulated motor open for re-wire and asked me where the earth go's :o

I may have to let natural selection take place next time and tell him to loop it into the live then bond it to his work bench.

240v is one of the more nasty dunts I've had, had to mcguyver a test lead together with only half a socket available "lets just shove a wire in here and....*******" :p

~115v isn't too bad to take a hit from depending on current.

Can't beat setting a megger to 1000v and asking a newbie to 'just hold these will you?' :D
 
MSI have truly shot themselves in the foot here. What are they playing at?

EVGA will be laughing, classifieds will sell out everywhere... In fact even I want one!!
 
Well MSI, we gave you another chance. Classified it is.

+1

I don't think I will bother with the Lightning's either, I will just make do with my other cards.:D

@MSI

I have a dish to serve up to you

Cold turkey

When you see your poor 780 lightning sales figures.
 
I really didn't want the classy....but no longer want the lightning considering what MSI have done. What is the chances blocks for the classy will ever come to the UK? If slim then i've lost all enthusiasm for the 780s and i'll be waiting for the red team to show their hand.

UK availability I'm not sure, estimate for EU availability is 4-8 weeks :)

hopefully EVGA don't muck around getting them to retail like they did with 680 hydrocopper blocks.

I really don't see who MSI are now going to sell this card to?

Gibbo is having an 'insanity sale' for the weekend starting at 6pm, I will be sitting eagerly awaiting the outcome of that :)

So 4-8 weeks, plus another week or so for delivery from mainland Europe :(
Knowing our luck it will be 8 weeks, might as well wait as i'll be somewhat paranoid without my cards being blocked up :eek: Can't have the side off all the time :D

I'm more interested in older cards rather than the current line up, I'll look forward to some crazy Gibbo deals this evening though! Hopefully be home by 6PM.
 
I am going to drop another bombshell here..

New 780's all flavours have been coming through without the samsung memory they were all reviewed with, it has been replaced with Elpida memory :eek:

Needless to say memory OC performance is massively down !

Anyone know the full story ?

Ah now I remember why I'm waiting for AMD.
