Will this PSU be enough to run an HD5850 mild to no OC and a Phenom 2 X4 @ 4.0 in an ASrock Extreme3 870 1 sprintpoint F3 a DVD-RW drive bunch o blue LED case fans 4gb DDR3?
no, it only produces about 360 watts 12v reliably, I'd not OC any part of the system with it.
(and that assumes its the best hardware on the market) The closer you get to the reliable performance limit of a given supply (think about 75% of "rated" maximum to be safe) the less predictable the power output becomes. If you run right up at the limit such things as air conditioners and sweepers can make the supplied power oscillate. If you're OCing a CPU oscillation is baaad.
This supply you listed is for older hardware that uses a lot of supply powered 3.3 and 5v. I can't think of anything manufactured today that even needs more than a few amps of 3.3 and 5 supplied from the PSU, most everything uses on-mb precision vreg running off 12v main.

very reliable company, $70 yes, but not having to replace the PSU is cheap
keep in mind this is advice, not saying it is a minimum necessity
Wanted to add something about "modular cables" saw tidbit in the review (someone whining).
Modular cables are for people who prefer clean over reliable. Each molex 3/32 peg is rated at a maximum of six amps, thus why our PCIe have three pins each. This assumes reliable sheath contact on each pin. (PCIe-8 only havs two more grounds, assuring the unit doesn't ground through the bus but it doesn't supply more than the 18amps the -6 supplies, total of 36amps or 432watts 12v )
So keep in mind that having twice the number of pin-and-sheath connections increases the chances of bad contact. Bit out of scale for the system discussed here but a good bit to know.
