    Default PSU Recommendations

    I am in the process of making a small upgrade (small, but expensive) for my current computer. I'm currently running the following:

    MSI RS482M4-ILD Socket 939 Motherboard
    AMD Athlon 64 3700+
    OCZ Platinum 2GB DDR PC-3200
    BFGTech 7800GT 256MB
    Hitachi 120GB ATA/100
    Hitachi 250GB ATA/100
    Antec Sonata II (450W PSU)

    I am looking at adding:

    BFGTech 8800GTX 768MB PCI-Ex16 Video Card
    Hitachi 500GB SATA HD (replacing Hitachi 250GB) x2
    Cooler Master CM Stacker 832

    This system will turn into a Media Server at a later date with the 7800GT going back in to this sytem and the 8800GTX going into a gaming system at the end of '08 when I upgrade the motherboard, processor, and RAM. I'm just trying to push push the life of this gaming system for a bit longer.

    I have been reading the stickies, and that brought even more questions to mind. ~grin~ The "Power Supply FAQ" mentioned that the wattage isn't really that important. I need to figure out "if your PC is going to be 5V heavy or 12V heavy." Which components rely on a 5V? and on a 12V? Since this system will most likely be hard drive heavy later on (just needs to work with a single 8800GTX for a year), what should I look for?

    I'll keep asking questions as I read the faqs. Good info. Wish I had found this site earlier.

    Your PC would have to be rather dated, or have a lot of "out of norm" devices in it to be +5V heavy. You're going to want a PSU with as much on the +12V as possible.

    by the end of 08, the 8800GTX will be relegated to the bargain basement much like the 6800 Ultra is now. Not that it won't still be a capable card in 16 months, but by then there will be mid-range offerings from both ATI and nvidia that outperform it.
    Rig 1: Phenom II X2 550-Asus M5A78L-MLX--2x4 Patriot DDR3 1333--Asus Formula HD4770--Enermax Triathlor 450--LG Flatron W2252TQ--Win 10 x64
    Rig 2: Core i3 6300--Asrock Z170M Extreme4--2x8 Adata DDR4 2400--EVGA GTX 750Ti--Corsair CX500M--Corsair Hydro H55--Windows 7 x64

    Thats why I do upgrades like this. One year I will buy the video card, the year after that I will upgrade my MB and Processor, etc. You're forehead will be a bloody mess if you try and keep up with all the latest hardware for you PC, not to mention you'll be broke. ~grin~

    Yes, 12v heavy is the way to go since that's what the video card uses... I've noticed if you avoid bargain basement PSU's that have old 5v heavy designs, you are going to get plenty of juice on the +12 rail. If you like your SonataII PSU then the NEO HE550 is a good seasonic build that's quiet and efficient. Depending on what kind of deal you can find, a Corsair HX520 would do the trick too. Of course that's just my $.02

    Thats what I'm asking for? ~grin~ I'm not looking for a bargain basement PSU, I'm looking for a good reliable PSU that will run the 8800GTX with out a hitch. Yet, still have enough power to run my old system and the 6 or so hard drives I will be adding at a later date depending on my storage needs once I start ripping my dvd collection onto the system.
