A good PSU should have at lease 30A on 12V and active PFC. If you want a decent PSU and don't want to pay the cost, get a dual 12V rail with at lease 24A total on 12V with active PFC. Those are usually a little cheaper than the single 12V rail.
Well im running a 519 3.06 (I will upgrade to Cedar Mill next year and needed a cheap one just to get me by) And an abit fatal1ty board with a 120gb SATA 150 Harddrive and a Gforce6600 Video Card. Will this PS be enough?
Do yourself a favor, CoreGamer, and don't skimp on the PSU. This is a common beginner's error. Don't even buy what you need. Buy more than you need because you will need more soon enough. The 500 watt Fortron ($79.50 shipped at ActBuy.com) is the least you should go with. I suggest you go up to the Sparkle 550 watt that Spider suggested as it's single rail and the 500 watt is dual rail. I don't know what eWiz gets for shipping, but it's $99 with shipping at ZZF.
The Sparkle/Fortron 550w recommended is the cheapest such PSU I know of that can be considered not skimping in some way. It's not geared for absolute silence and is not the most efficient design by today's standards, but it will do rated power and last and last and last. The modular capabilities of the Ultra do look good, but that's exactly what you're paying for with them - the Wintech made innards are average quality.
The Fortron AX500-A will also power that rig if you're looking to save a little more money - it's not a whole lot cheaper than the 550w PLG, but has a little more bling factor to it and a 120mm fan.
I'd suggest avoiding modulars entirely if you're on a tight budget. The better ones that are ok quality inside will probably set you back more than you want to spend. Right now, the only two modulars I like are the Seasonic made Antec Neo HE's and the Enermax Liberty line. I'd suggest no lower than 480w from either line for a P4 build.
I want at least 500W and I have 120 Dollars(I dont think thats very tight for a PS). Thanks for all your help so far Wolf. Do you think that Modular would be bad? I have no problem getting that fortron but having a modular like that ultra for only 100 Bucks looks good, but of course your the expert so Id like to hear what you say
