| 810840 | 2009-09-16 09:38:00 | Hey everyone I have the following PSU www.newegg.com Output +3.3@30A,+5V@30A,+12V1@20A,+12V2@20A,-12V@0.6A,+ 5VSB@3.0A 2X PCI-E 6 Pin and SOMEHOW SLi Ready at only 420W???? I have the following choice to make A HD4770 or a HD4850, The HD4770 literally consumes like half the amount of power due to it being 40nm and nearly performs the same, but in NZ it costs MORE than the amazing HD4850 SONIC Edition which is waaaaay faster than both but reccommends a 500W PSU. So what do you guys think? 4770, 4850, or 4850 SONIC (needs 8-pin but can get 6-pin+4-pin adaptor) (I can get both 4850's $10 cheaper than the 4770). Also what do 'rails' mean, someone on another forum was talking about the 12V rails needing to be 30A or something? How do I combine both 20A's, Cheers. |

| 810841 | 2009-09-16 09:47:00 | I wouldnt, if its the system in your sig then everything else will be bottlenecking anyway | hueybot3000 (3646) | ||
| 810842 | 2009-09-16 09:49:00 | Also 'reccommended' PSU req's 4770 - 450W - $179 4850 - 450W - $167 4850 SONIC - 500W - $178 Also the Sonic edition is ALOT faster than reference. |

| 810844 | 2009-09-16 09:53:00 | I still wouldnt bother, one would be more than enough. But if you do decide to do it you should probaly get a bigger psu, youve got a decent brand but i fear just not enough juice in the long run | hueybot3000 (3646) | ||
| 810845 | 2009-09-16 09:56:00 | Grab another 2gb of RAM for starters. I would get the 4770. Two in crossfire pwns a 4870! More overclockable too. the 4850 sonic isn't that much faster anyways. Blam |

But if you do decide to do it you should probaly get a bigger psu, youve got a decent brand but i fear just not enough juice in the long run EVERYONE. I don't want to SLi, I'm just like 'WTF a 420W SLi PSU..How the hell'. I want to know if this 420W 'SLi' PSU could comfortably power a 4850 sonic requiring a 500W PSU, or a reference 4850 requiring a 450W PSU. Also was enquiring about the two 20A 'rails'. If i got the sonic edition (500w version 8-pin version) would I use an 8-pin adaptor (4-molex + 6-pin pci) and take a molex 4pin from one 'rail' and a pci-e 6pin from the other 'rail'. So there are 2 sets of cables split? |

Blam The Sonic may only be slightly faster in some games, but in others it blaaaazes ahead and the cooler on it is friggen awesome!!! |

No it couldn't. Forget rails, if you want to know how that works - Google it. hardware Secrets website has some good articles explaining it all. You can use an adapter but I personally would just buy a PSU that already has all the necessary connectors. As for the SLI - well if you used 2 really low-end cards then I guess it is SLI ready. |
