Hey
i have just ordered myself this card to replace my current 560GTX (which has been awesome, but its time to move on and up)
http://www.amazon.co.uk/EVGA-GeForce-Cooler-GDDR5-SDRAM...
after reading up on the wattage required, i happened to notice that the card asks for 42a on a 12v rail, and after looking up the details of my current PSU, i realized it only has 40a on 2 12v rails...which i believe to be to low...
Am i right in saying that my current 750w wont have the amp power on the rails to take the new card?
if this is the case, i have been looking for good budget PSU's and came across this one:
http://www.amazon.co.uk/Corsair-Builder-Series-Modular-...
given that this PSU outputs 62a on a single 12v rail, its more than enough to take the card, is it a good buy?
Thanks for the advice guys

Don't get a CX. They are crappy. Get a blokes psu - Seasonic M12II 620 eg http://www.overclock.co.uk/product/Seasonic-M12II-620-6... 70 quid

What specific model and brand is your PSU? 40A on 12V line means the PSU technically has 480W supply limit (since, Power=Ampere*Voltage), and the maker can't really put 750W tag on that.
If its 40A+40A, then you'll be alright, 40A is enough amps for the card, you can stick the MoBo and CPU power to the other line. 40A is the total system power which is required on full load (on text rig, of course) and not for just the GPU, otherwise it'd be 40A*12V=480W power comsumption from GPU!
Don't look at individual Amps on each 12V line, what's the total max load? There should be something like 60A or higher.
And in any case, DO NOT GET CORSAIR CX/ VS/ VS/ Builder, they're extremely low quality. That GPU can work on a S12II 620W with ease, do not go with CX. Any 600W+ EVGA/ Antec/ SeaSonic/ XFX PSU will be fine

Its a low quality PSU but looking up for Amps, it seems fine:
+3.3V +5V +12V1 +12V2 -12V +5VSB
Output 28A 30A 22A 22A 0.3A 2.5A
44A (or even 40A) is plenty for the card, provided the PSU doesn't explode while on high load.
The card WILL NOT require more than 250W which's ~22A, 44A is recommended power for the whole system, not just the GPU, unless you have a FX 9, you're fine
PS: Of coure, if you can get S12II 620W, then nothing like it!

this is the spec of the PSU, if it helps
you think it will be fine Meteors?
if thats the case, am i ok using a 6pin to 8pin PCI-E cable, as the PSU only has 1 PCI-E cable atm (the other is 2 molex to 1 6pin PCI-E i am using for my current card)

Wattage wise its under limits, but I can certainly say it won't live up to the power demand, quality wise. Agree with i7 there.
Cable config is fine, but as said, PSU's gonna fail. I just researched about that brand a bit, brand's not reputable on high loads. I'd just get myself a SeaSonic. I can't recommend using GPU on that PSU after reading up the reviews.
i7, I hope it does
