    I would get at least a 400W. I have a Nexus 500w for mine.

    ull struggle with that power supply the bfg reccomends a 400w PSU. I would get a new PSU if funds allow, as uve just got rid of 6600gt then im guessing ull still want to upgrade to something decent maybe a 480tagan for example and a 6800gt? - or Ati x800gto2 and overclock it if your ok with that type of stuff

    Permanently confused

    You will not struggle with that power supply!

    A 300W PSU wil be fine. I just built a pc on saturday with a 300W psu and an pre-overclocked XFX 7800gt. Runs like a dream even though on the packaging it says 400W min psu required.

    Dont bother getting a new psu.

    It really depends on wat sort of 300W he's using.. and how many pheripherals he installed.. say 2 opticals + 2 drives in RAID + 1 backup drive + an overclocked CPU would crucify most 300W PSU.. unless ur talking about those BlueStorms from FSP..

    If ur system has nothing in it other than the most essential.. a good 300W should be more than enuf..

    Check to see if the 300w is a good one first. Nothing wrong in getting a better PSU. Always good to have a reliable / powerfull PSU for future upgrades!

    You've had it since Saturday. Some people might think that's a bit early to be crowing about how your system runs like a dream on your 300W PSU, but I couldn't possibly comment.
