Hey all ...

Ok firstly I have a old pc, I know this so please don't tell me I need an upgrade as this is a second system not a main system. Secondly I am from South Africa and prices are rediculous ... lol


My question is this ... I have the following system ...


Pentium 4 630 @ 3.4ghz (overclocked)
2GB DDR 400
Sound Blaster Audigy
2x DVD RW Drives
2x Sata Drives
7600GT (AGP)

and 8 system fans.


Would the Corsair 450W be stong enough as my power supply is starting 2 give in it goes for R760 (approx $100 us) it puts out 33A on the 12v rail ... and would this handle minor system upgrades (new gfx card and mobo)


All information would be greatly appreciated

Kind regards.

What graphics card were you looking to upgrade to? The 3850 AGP requires a minimum 450W PSU, so the Corsair 450W should be able to work it.

Hi anacandor,

I was actually looking at upgrading my motherboard to something like a g31 board. That way I can keep the processor a little while longer and i can change ramm to DDR 2 and the gfx card to a PCI Express card and later getting a new processor ...

Newer processors and GFX cards use less power dont they ??

Well unfortunately I am an nvidia fan ... dunno why but there it is ... I was looking at maybe the 460 GTX and an E8400 ...

I have another question ... ... Dual 12v rails or single ... which is better (I will never run sli) ...

The reason I ask is that I can get a 450w psu with 33amp on the 12v rail (corsair, single rail) or a 400w psu with 36amp (ocz, dual rail) ... which would be better ?? ...

The 400W OCZ won't have enough juice anyway for a 460 GTX anyway, it needs around 450-500W. I personally don't trust OCZ's power supplies, they've been given some bad reviews. Go with the Corsair :)

I am suprised how little input other ppl are putting in ... It's almos tlike they only comment on the new tech threads 4getting bout the underdogs ... They all started somewhere ... bleh ... anyway ...

Any opinions on single vs dual rails ?? ... and how much difference is there by having a couple more amps (less than 10) ...


THANK YOU SO MUCH for your responses so far ...

There should be very little difference between single and dual rails. the Corsair 450W looks like a good choice.

Thanks for that ...

I am thinking of saving a little and getting the Corsair VX550w just in case ... is there any system with a single GPU that uses more than 41amp on the 12v rail ??

Sign the register and wait in the lobby , someone will get to you :lol:

Doesn't really matter with good quality power supplies and lower end systems

Well 2 amps would be close to meaningless, 8 amps could be the difference in what your system can or can't run.

I'd wait till I had the money for the 550, there are single gpu systems that would require more than 41a , but it doesn't sound like you're heading there.

HAHAHAHAHAHA ... Ok ... I was bein impatient ... I do apologize ... I have read many threads on this forum and they all have mega replies ... I was just hoping 4 lots of input cause then I can learn more ... :lol:

Ok ... that kinda sounded insulting ... lmfao ... but I know it wasn't ... which single GPU system would need more than 41amps ... according to Corsair's website (power supply finder) ... They say that a VX550w would run an overclocked i5 with a 460GTX and 2 hdd's ... ... was I duped ?? ... lol



The reason I asked about the less than 10 amps thing is cause the OCZ Fatality 550w (even though I was warned against it, it's just for comparison purposes) has 50amp on 2 rails (25amp each) which is 9amps more than the corsair ... ... How much difference will it make considering each rail will only get 4.5 amps more ... ... how do you know which components will be on which rail ... gpu is dedicated what is the other for ??


Sorry for all the questions ... :pt1cable:

The VX 550 could handle that system, but there are video cards that require much more power than a GTX460, and systems that have more peripherals attached.

The OCZ isn't 50 amps ( 600 watts ), you can't add the rails , have to read the label to find out the max wattage available to the 12v, it's 37 or 38 amps combined.

Read the picture of the power label
450 watts for the combined 12 output
450w/12v=37.5a

WOW ... that is really sneaky ... so they are basically false advertising ...

Thank you for pointing that out ... I suddenly feel very worried about supplier stickers now ... lmfao ...

A little deceptive, yes. Not quite false advertising. The full data is on the PSU label.

But even then, you know that something is not right. 50 amps time 12 volt equals 600 watts - from a 550 watt PSU?

That is understandable ... But then again ... if you look at the corsair psu ... the amperage checks out ... 41*12=492w ... but then it says that 3.3v + 5v = 140w ... 492w+140w=632w ... lmfao ... I really think that once u start goin into details ... it just gets more complicating ... lmfao

Just to close this Thread ... I hae gotten the VX550w


THANK YOU TO ALL FOR THE ADVICE ...
