Rosewill Green Series RG430-S12 430W

Most enthusiasts are familiar with Rosewill as an US brand of inexpensive products of decent quality. They've had power supplies on the market for ages, but those products are almost always for budget builds. This time Rosewill sent a PSU which is more "expensive". The Green Series is efficient (80Plus) and comes with several extras such as cable ties. The 430W unit can theoretically draw up to 10A from the power grid (115VAC), and it delivers up to 33A on the single +12V rail. The maximum output from 12V is thus 396W if you don't stress the other rails, which are both rated at 24A. Together, 3.3V and 5V can deliver an additional 140W, which is more than enough for a system with modern components such as SSDs.

At first we couldn't identify the manufacturer of this fan as Rosewill is the only name we saw on the label. However, the model number S1202512M told us that GlobeFan is the company behind. This sleeve bearing type has a maximum rotational speed of 2400RPM.

Cables and Connectors

Connector type (length)

Main 1x 24-pin (55cm) fixed
ATX12V/EPS12V 1x 4+4-pin (50cm) fixed
PCIe 1x 6-pin (45cm) fixed
Peripheral 2x SATA (ca. 40, 55cm) fixed
2x SATA (ca. 40, 55cm) fixed
3x HDD (ca. 40, 55, 70cm) fixed
3x HDD, 1x FDD (ca. 40, 55, 70, 85cm) fixed

Here we have a typical ATNG design with two large heatsinks. The EMI filtering is equipped well and it's nice to see that there are Taiwanese capacitors. The Teapo models don't have the longest lifetime and lowest ESR; however, we've never detected a problem with Teapo in power supplies.

    I'm not sure how hard it would be, but would it be possible to write up a review of a few PicoPSU adapters? I've considered a few for low-power builds, but I've always been wary of the little no-name sealed plastic bricks that come with them.

    Then again, I don't know if Anandtech would be the ideal audience for such a review.

    Ditto. I own a wide variety of PicoPSU and other related electronics from mini-box/ituner, as well as some similar Antec DC-DC products. I would love to see more of this stuff reviewed, with some emphasis on the "black box" bricks that can be had for very little outlay in some cases. Reply

    This!! Please.

    It's difficult to find information on suitable adapters, and it's kind of a critical part of the build given how little PicoPSUs filter their input (afaicr).

    I noticed that the enermax PSU that you reviewed is not the same as the one on newegg. In the gallery, (this pic:http://www.anandtech.com/Gallery/Album/2123#7) the model is ENP450AWT.

    However, you say you are revieweing the ENP450AST, which is the one available on newegg.

    The ENP450AST (newegg link:http://www.newegg.com/Product/Product.aspx?Item=N8... lacks the 80 plus bronze certification and has less sleeved cables as far as I can see.

    So, it seems you have reviewed the wrong psu...

    sorry, the link was wrong for the psu on newegg

    here is the right one: http://www.newegg.com/Product/Product.aspx?Item=N8...

    I love those manufactureres with hundreds of versions. Ironically they didn't want me to review their Triathlor 385W as it is "not available in the US".

    The AST is also a good PSU.

    However, pricing will be a problem now.
    Thank you for this correction.

    AST is also a good PSU eh? I trust you know what you're talking about - care to elucidate? I shared this on this thread in slickdeals and your post/comment about the Enermax will get some attention there so your comments would be much appreciated by many ;)

    I find that the one crucial point missing in ALL computer hardware reviews is long term reliability. It's understandable given the circumstances, but I wish there were some way for hardware reviewers to do some kind of simulated stress testing. I have found over the years, especially with motherboards and power supplies, that the reviews that award winners based on their feature set don't always do well long-term. The only way I've found to get an indication of this factor is through user reviews, which is not a perfect either as most reviews posted a few months past initial purchase are negative. Still it gives me a little better way to compare.

    I personally have had quite numerous failures 6 months+ out with excellently reviewed hardware, especially when its a lesser-known brand or a newcomer to the field.

    You can get some idea from the quality of components used, the soldering, and so on..

    But yes, a soak test would be nice.

    HardOCP does something close to this - their Torture Test - 8 hours @ 80% load, which is quite a nice test. Maybe something like this but for a bit longer?

    Maybe with a high ambient temperature.. Maybe some power cycling during the test (to full cold, then back on again) to test cold joints and how well the PSU copes with heat cycling.

    I don't know, just some ideas. But yeah, these tests would quite a bit of time.

    Look at the product's warranty and its terms and conditions. Pay close attention to how long the warranty lasts on replacements. A 5-year warranty doesn't mean much if they're only guaranteeing the replacement for 90-days. The longer a company is willing to allow easy and (mostly) free replacement of the product, the longer they're guessing it should last. Divide product price by the number of years the company allows hassle-free replacement for a rough estimate of long term value.

    Of course, this doesn't apply to new brands that simply haven't been around for very long, or brands that are simply rebadging cheap 'no-name' vendors.
