    Advice for replacing a power supply [Desktop machine]


    Right now my main computer is down with my power supply being dead. Right now I do need to get something on the cheaper side tho honestly I am really not to sure with what I really need for my system. I had a 600W power supply surely a little overkill for what I had and since I am on a budget looking to see what lower I can do and work with.

    I know for the most part all I have in my system (the only thing I am not fully sure is the exact model video card other then it is a 9800GT asus card as not the exact same one I had as one point I had to RMA my old one and it was replaced with a slightly different card.

    CPU is a AMD Phenom II X4 975 Black Edition Deneb Quad-Core 3.6GHz Socket AM3 125W Desktop Processor HDZ975FBGMBOX

    Ram is CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9

    Video card is Asus 9800gt 512 MB card

    Motherboard is MSI 870A-G54 (FX) AM3+ AMD 870 SATA 6Gb/s USB 3.0 ATX AMD Motherboard

    Other devices is 2 sata hard drives and one sata DVD burner along with a few USB things like headset, mouse, and keyboard.

    I am looking for some good advice as to what I need for a power supply how low a Wattage I can do and have it run right so I can start searching for something within my budget.

    nVidia GeForce 9800 GT Video Card - Reviews, Specifications, and Pictures - GPUReview.com

    Above link says power consumption of the card is max of 105 watts. Modest by today's standards

    I think the so called recommend minimum psu is about 400 watts.

    I'd search for a good brand in the 400 to 550 watt category.

    Good brands are XFX, Seasonic, and some EVGA, Antec, and Corsair models.

    The Corsair CX430 is often the lowest priced decent PSU of 400 watts or more. Sometimes under $50 and sometimes down to $20 including rebates.

    If you can afford it look at the Seasonic 450 G series, at maybe $75.

    Prices for good PSUs at 500 or more watts usually go up from $75 unless you can catch a sale.
