Powersupply and Case for My New Rig? Help Appreciated

Hi, can anyone help me out pick out a nice power supply for me? I originally was only going to get a 7900GS, but someone directed me to an 8800GTS. I thought if I just get a cheaper case, I can afford it. But, I have a problem; I don't know what power supply to get!

Seagate Barracuda 7200.10 ST3320620AS (Perpendicular Recording Technology) 320GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

EVGA 320-P2-N811-AR GeForce 8800GTS 320MB GDDR3 PCI Express x16 HDCP Video Card - Retail

CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400C4 - Retail

GIGABYTE GA-965P-DS3 LGA 775 Intel P965 Express ATX Intel Motherboard - Retail

Intel Core 2 Duo E4300 Allendale 1.8GHz LGA 775 Processor Model BX80557E4300 - Retail

I also have a CD/DVD-RW and a floppy drive, if that counts.

I havn't decided what case to get either, I was going to get an ANTEC Performance series, but I had to cut that off because it made me go over my budget by a few dollars because of shipping.

Thanks much in advance. :)

More about powersupply case appreciated
  1. My suggestions using Newegg's "Advanced Search":

    - Dual 12V - Yes
    - Active PFC - Yes
    - SLi Support - Yes (For future expansion/new builds)

    I would stick with brands like Enermax, Thermaltake (Toughpower), Seasonic, Silverstone, and Corsair (and others can recommend other brands).

    I would say around 500W should be your goal (again for upgradeability).

    Also, make sure that you check the amperage on the 12V rails; generally 20A on each rail would be the minimum (though I'm using 18A on each rail with a total of 4 rails). I'm sure more experienced users can correct me if I'm wrong...
  2. That's really confusing...

    Could you point me to a link, that would help me the most. :P
  3. I normally don't like to recommend something just because I own it but our rigs are almost the same, so here are some reviews for the power supply I decided on.

    Here is the cheapest trustworthy place to buy it:
    http://www.provantage.com/~7CSMC02X.htm

    This PSU is made by Seasonic, has 40 amps on the 12v rail and is very quiet.

    I already selected the above options that I recommended.

    40 amps, perhaps, but I heard that overall amperage (which you provided) is misleading because rails are independent of the amperage supplied to a specific device. (Not sure where I read that, but somewhere on this forum). My TT Toughpower supplies more amperage overall (56 amps) but maxes out at 18A per rail.

    EDIT: Here we go; use this as a better reference:

    EDIT II: BTW, what is your budget for the PSU? That would help us better choose/recommend a PSU.
  5. Cheapest would be the best... Under $50, so that I can still have enough money for a case. Thanks guys, but those prices are insane. I'm going to have to wait until my next paycheck...

    I know what you mean but this power supply will share loads between the 12v rails
    Here is a quote from SPCR Corsair Review
    "Triple 12V Rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (40A on 520W) maximum! Advanced circuitry design that automatically enables power sharing between the triple +12V rails in an event of overload on any single +12V rail."
  7. Here is a cheap case and powersupply:Ultra Xconnect 700watt
    Legion Hardware used it in a resent budget build:
    http://www.legionhardware.com/document.php?id=661&p=3

    I doubt it will reliably put out 700watts, but for what you need it should work.
    Waiting for your next payday to buy the Corsair is probably a better idea.
