    I have a 9 month old Antec 300w power supply that came with my case that says it has 15A to the 12v rail. I currently have an Asus mobo, Barton 2800+, eVGA 6600GT, and an 80 gig HD in there. Runs perfect. I'm upgrading to an ASRock Dual SATA2, Opteron 146, ATI X800 GTO modded to 16 pipes. Do you guys think I need a new power supply, or will this one do the job? I'm only spending $430 for the three new parts and really don't feel like throwing another $50-$75 into this unless it's absolutely necessary.

    Thanks!

    EDIT: Just thought about something. My new card will be PCI-Express. I'll need a new power supply regardless, right?

    Yeah, you would definitely need a new PSU. Maybe a 350W could've worked but I think the 300W is just a tad too weak for the 146 and GTO. Also, like you said the PSU needs to have the 6pin PCI-Express connector as well. I guess you could get an adaptor for it but I wouldn't recommend it. A 400W good quality PSU should be sufficient. It will be a kick-ass system once you get the parts though! Good luck. :D

    Your 12v amperages are horrible. Try to get something with atleast 20-25a on the 12v rail. I would suggest a 420w OCZ PowerStream if you have the money. Most bang for your buck, awesome PSU.

    its not only an issue with watts, you should buy a solid 400 watt minium PSU, but since your going to be feeding that X800 GTO from the PSU, your going to need a PSU with atleast 24 amp on the 12v line, (also makes your machine more stable and gives it better overclocking potential),

    i have a 420 watt bequiet, quite a nice PSU, gives 27 amp on 12v, can do 30 at peak (not recommended for long periods), your going to buy good equipment, the 939Dual-SATA with a couple of solder points makes an excelent board, and a X800 modded to 16 pipes can easly reachy XT speeds, but it all depends on the psu you choose,

    that 300 watt wont get you very far, especialy with that 16 pipe GTO

    Def. upgrade that PSU. I suggest going for an Antec TruePower, OCZ PowerStream or ModStream or even an FSP. Check out newegg.com they have a few sales on a FSP and the OCZ's PSUs.
