I'm going to do a quick run-down of the leading 380-450W power supplies on the market right now below $50. All five have their pros and cons, so I'm going to leave it up to the reader to decide.

Any of these should power a low-end to mid-range rig reliably (up to a moderately overclocked quad core and a Radeon HD6850), and I wouldn't feel bad recommending any of them. I do have my favorites, but I'll leave it up to you to evaluate your options. There are other options--but these generally appear to make up the best bang for the buck choices under $50.

Does itocp use a hot box for testing (not like any of these units could power a system that would really really heat up a case)? They have a review on the Earthwatts Green 380D.

http://www.itocp.com/htmls/48/n-1948-9.html

They measure 77 mV on +12V at full load with under 30 mV for minor rails. (That's also about what was reported in the Anandtech review, though their testing leaves something to be desired.) Voltage regulation is good even with weird crossloads, so that's something else to consider.

Thanks for pointing out that review, I hadn't seen it. ItOCP is good for reviews, Travis is among the most knowledgeable PSU reviewers I know of.

EA-430D is good of course, but it can't reliably be found for under $50; $45 is the lowest I've seen it, usually it's up around $60.


By the way, does anyone know anything about this unit?

I heard the lower wattage NAXN units are CWT DSAII ~ I'm not sure though. I haven't seen any internal shots.

I don't think it's a DSAII. It doesn't have PFC, and looking through the backgrille it's totally different from the CX430.


EDIT: It's a CWT PUF. Compare the Newegg pictures to this:

so what would consider mid-range? it is probably a stupid question, but anything with an sli/crossifire settup of two mid range cards i would consider high end, but they don't require a psu above 450w........

Like I said: a moderately overclocked quad core and any GPU up to around an HD6850 is midrange.
