Replacing Inspiron 531 PSU

[Nshimley]

Hi guys, I'm new to this forum and need some help please! I bought this graphics card off of ebay a couple days ago: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150570, and didn't realize that my power supply is only 300w and that it required 400w minimum. One question I have is whether the inspiron 531 psu is proprietary or not. Will these ones I found on ebay fit? Also, are they reliable?? (eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices) (eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices). I'd like to be certain about my options before I purchase. Any help provided is greatly appreciated. Thank you!

I would buy a psu off newegg from a reputable brand, rather than a Dell replacement. It doesn't look like it's proprietary, they've been using standard ATX psu's in their main line desktops for a while now so you should be ok.
