Need advice for my PSU

[rizkinof]

Hello guys, this my first thread
So let's to the point
my computer's specification is like this:
Procie : Amd Phenom ii x2 555 BE 3,2Ghz
Mobo: Gigabyte GA-MA74GMT-S2
VGA : MSI R6850 1Gb 256bit
HDD: Hitachi 320Gb + Seagate 80Gb
Memory: Visipro 2x4Gb

And the question, what is psu that suitable for my rig?
the price under $100 and where to buy
Thanks

A system with a single HD 6850 requires a 450W PSU with one 75W PCIe power connector and at least 28A on the 12V rails. A great deal on a great PSU right now is the Seasonic M12II-520 at Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093&Tpk=m12ii%20520 Hard to beat at $68 shipped. The PC Power and Cooling MKIII 500W is a good deal, too, but you have to wait for a $20 rebate and the additional promo is a $15 gift card instead of immediate discount on the product: http://www.newegg.com/Product/Product.aspx?Item=N82E16817703035

There are two things that come to mind when we talk about PSU: brand and cable management for a good air flow inside the case.

The eXtreme Power Supply Calculator results in almost 400 watts as the recommendation. Personally, for this system, I would get a 500-550 watt PS as a minimum. XFX Core Edition 550 watt Pro (Seasonic) is a good one. Another is the Antec HCG-520 or HCG-620 (Seasonic). PC Power & Cooling Silencer Mk3S500 500 watt or Mk3S600 600 watt (Seasonic) are other choices. If you are planning to crossfire with another 6850, get the 600 watt PS. If single 6850 only, a good quality 500 watt should do.

Seasonic, Corsair, XFX, can't go too far wrong as rec'd above.

Don't skimp, better to have too much power than not enough or on the limit.

What case do you have?

Do you need modular?

The Seasonic that Rugger suggested looks too good to be true atm for your current setup.
