  1. What country are you in?

    If it's the US, then these are good deals right now.

    PC Power & Cooling S61EPS 610W
    CORSAIR CMPSU-750TX 750W
  2. 570w is still enough with the overclocking, ample headroom too, you don't need to buy a new one.
  3. True, but I don't trust Trust. :lol:

    Who are they, do you know?

    Brands aside, the power level is more than high enough. No reason to not try it out. Unless defective, it'll work.
  5. thanks for the replies but i am in England so the deals dont apply to me

    as for the "brand aside comment" i took this approach the first time and now i need to upgrade. I am looking for a reliable psu with good reviews, that i can trust, what brand do you thin i should go for?
  6. What site do you order from?
  7. You know, you're not actually changing hardware, just ocing. And it doesn't go anywhere near the limit of the psu. Since your old one worked fine so far, it's a good bet that it's not defective and will continue to work when load is slightly higher.
  8. I will order from any uk site
  9. Using the eXtreme Power Supply Calculator Lite v2.5 with an OC of 3.2G and Vcore of 1.35, which are both high, I got a recommended PSU size of 453W. All loads were at 100% and the VGA was a 4870. With a capacitor aging of 25%, the number climbs to 566W. So I would go for 600W or better for long term use, and future expansion.

    I found a really good choice, but it isn't in stock yet. It is a good PSU and is relatively cheap. You could call them and get an ETA.
    Scan Computers UK: TX650W Corsair PSU OEMed from Seasonic

    Another good choice, but expensive because of the modular cables.
    Tekheads.co.uk HX620 OEMed from Seasonic.

    The least expensive and good, but not as good IMO.
    ANTEC EA650-GB/Earth Watts Used to be OEMed from Seasonic with a lesser build spec., but now OEMed from Delta. I haven't seen any Delta OEM reviews.

    Larger than you need and more expensive, but excellent.
    PC Power & Cooling SILENCER 750 QUAD (Black) OEMed from Seasonic.
  10. thanks zorg, thant helped me alot, i am liking the corsair, and it is a brand that i trust.
  11. Corsair is a good brand. I'm not a fan of the modular cables on the HX, but I think I might be in the minority.
  12. modular cables?

    do u have any suggestions for psu for overclocking
