Power supplies are one of the items where mfgs can really cut costs. The cpus, hard drives, and for the most part sdram, are going to be the same in a pre-made or build-your-own. But the PSU? Those $15 power supplies that you (hopefully) would never buy for your system are exactly what Dell and HP and Acer and Lenova are putting in their boxes, and the cheaper the box, the cheaper the PSU.
You can be confident that it's junk. Yeah, it may work, but that's due to luck and not being heavily taxed primarily.
Go read Assassin's hardware guide, and JohnnyGuru.com, and Tom's hardware, for solid info and reviews about power supplies. Pay absolutely no attention to Newegg reviews. None of those people have torn their psu apart, examined the internals, and tested the components. Their comments are of zero value.
The absolute best buy in a power supply you're going to find right now is the Corsair CX-430 v2 that Newegg has been selling for $25 after rebate. Read about it here - http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=239
