  2. Hi.

    Here are the system requirements for the 5970.

    ATI Radeon™ HD 5970 System Requirements

    PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
    650 Watt or greater power supply one 75W 6-pin and one 150W 8-pin PCI Express® power connectors recommended (850 Watt with two 75W 6-pin and two 150W 8-pin connectors for ATI CrossFireX™ technology in dual mode)
    Certified power supplies are recommended. Refer to http://support.amd.com/us/certified/power-supplies/Pages/listing.aspx for a list of certified products
    Minimum 1GB of system memory
    Installation software requires CD-ROM drive
    DVD playback requires DVD drive
    Blu-ray™ playback requires Blu-ray drive
    For an ATI CrossFireX™ system, a second ATI Radeon™ HD 5970 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required

    The recommended PSU is for the entire system.

    This Corsair 950W TX should be enough
  3. In benchmark testing guru3d claims it needs at least 70amps on the 12v and ~894 watts. 78amps from the Corsair may be a little tight with upgrades.

    strictly no offence intended, but I can't believe you are not sure about the PSU after planning that rig.
  5. I was looking at a antec tpq 1200 watt what do you think ? I'm gonna ove clock a little to
  6. That would certainly do the job. It's a very nice PSU. It's more expensive than most of the suggestions, but judging by your build, that's not a problem. :)
  7. The ANTEC is overkill for the rig IMO. Like u can see u can go with a 950W PSU without problems.
  8. hey guys, well i was looking at Antec TruePower Quattro TPQ-1200 . but im gonna be hooking up to ati radeon 5970s 4gb each video cards in crossfire , i think thats correct. i think i need 2 6 pin and 2 8 pin connections on the powerspply right?what one would be a good model with that , and i want it to be 1200w or so. thanks
  9. I still believe the 1000w Kingwin is the best price/performance option for this setup.

    That 950w Corsair would be cutting it a little close for my taste.
  10. OMG.!! This is a huge build.. All top of the line components so better get a top of the line PSU.. Something like the Corsair AX 1200 (am sure you can afford one, not so sure on the availability though).. BTW, just for curiosity sake, what is the hard drive configuration and which case have you selected.? Also, which 30" monitor and how many.?
  11. Use this I think that is enough for ur rig :lol:
  12. lol true thats funny, i was looking the Antec TruePower Quattro TPQ-1200 , does have what i was looking for it has 2 6 and 2 8 pin ones. but is there a better psu or should i just go with this one, the others ya guys metioned are pretty good too, but what is the best one,

    for emperus , hdd config? what do you mean, ima have windows 7 64 bit im looking at gettinga 600gb raptor harddrive and on case i have a antec 1200 case. its big as all hell lol.
  13. That Quattro is a very good PSU thes pass days I OC and Intel i5-655K @ 6.3GHz (with phase change), with a 5770 HAWK and OCZ Reaper with that PSU and is very solid.
  14. Does the Antec 1200 fit the Rampage III..?? Am somewhat doubtful on that..
  15. ^Why not? The Rampage III needs two 4 pin connector 12V and the Antc 1200 have it.

    I mean Antec 1200 the case.. Not Antec TPQ 1200 the PSU..
  17. ^It's the same.

    The Antec 1200 is a full tower and support ATX mobos and the Rampage III is an ATX mobo.
  18. My bad.. I thought the Rampage III to be an E-ATX board..
