Antec Earthwatts 430W

We begin with the Antec Earthwatts 430W. Antec's Earthwatts series first became available around a year ago, with the "earth" in the name apparently there because the product is more environmentally friendly. The design and appearance of the Earthwatts 430W bring us back to a time when nobody was asking about shiny coatings and sleeved cables. The housing is a simple grey color, similar to what we see on OEM power supplies. The back has the expected AC jack and a power switch, along with an 80mm fan that provides cooling. This is a different approach to cooling than what we'll see with the other units in this roundup.

The label provides the typical information we find on power supplies, with the expected figures for a 430W maximum output. Two 12V rails of 17A each are enough for most users, and the combined 12V power of 360W is quite acceptable. 360W combined equates to 15A when both are "fully" loaded. We would be hesitant to try to use this PSU with one of the top-end graphics cards, but if you're using a power supply with a single 6-pin PCI-E connector you should be fine.

Other than the main 24-pin ATX power cable, the cable-harnesses are sleeveless. Antec has taken a very simple approach in terms of appearance, and the only concession to keeping the cables tidy is the use of cable ties located over the length of the cables. The length of the harnesses is average, with the last Molex connector just 80cm distant from the power supply. The main connectors are all on 50cm cables. The quantity of connectors could have been better, but a normal midrange PC shouldn't require more than what Antec has provided. There is only one 6-pin PEG connector, which makes sense considering the overall wattage and target market.

The inside looks quite familiar to a couple previously tested power supplies; indeed, the same manufacturer produces this power supply as well. Of course, that doesn't mean the power supplies themselves are actually the same. There are several differences, and we expect this unit will be at a slight disadvantage. Antec uses an 80mm exhaust fan located at the rear of the power supply, but the heatsink design would normally use a 120mm intake fan. We expect this unit to be slightly warmer and/or noisier than similar designs that use a single 120mm fan. Nippon Chemi-Con manufactures the primary capacitor

    Yep, otherwise it's just getting too long and I thought actually nobody is too interested in that analyses anyway. Let me work something out for the next ones...

    Ripple is also coming today, I updated the 1200-1300 roundup already.

    Good to know! I understand that it is going to take a considerable amount of work at the outset, to do a bit of design analysis, but once you have the popular topologies employed figured out it should be a lot less work.

    The length of the review is unimportant if it makes an interesting read. (Hypothetical example) Having 10 pages on the fans employed is going to be be boring. Since you have a wide audience with varying degree of technical appetite, the length of the review should not matter if the content is arranged appropriately.

    Best wishes,

    When referring to the 8800GT article, it'd be nice to point out that those 327W from the wall was with SLI. A single card didn't get much over 200W, so even the Ultra should be able to run that, however horrible it otherwise is a a PSU.

    As for the market, I just wish someone would produce a high quality 300W modular PSU. That'd be plenty for my needs.

    Would you be ok if they charged you the same as a 400w PSU? because for the manufacturers, they're not going to the trouble of making another PSU that costs them almost exactly the same to make.
    (its like asking for a car with only 15hp because thats all u need ;)

    Exactly. The cost difference at that level is rarely more than a $1. So if it costs me $30 to build a 400W, and $29 to build a 350W, etc. why would I bother? Reply

    maybe because some people "think" a 350w power supply consumes 50w less than a 400w power supply...

    My 430 watt Antec Earthwatts that I bought in 2008 just failed. 12 years, pretty cool. Guess the 80mm fan didn't hurt its longevity. I know no one is going to read this in 2020 but wanted to post it anyway. Reply
