Quiet and Efficient PSUStrengths: Efficient, quiet, easy to set up Weakness: No modular cable management This Antec PSU appears to be a very solid build and has performed stably for 3 months with very low noise and low heat. Multiple testing sites have reported and confirmed its 80+ efficiency. The only downside is that there is no modular cable design, and there is a lot of clutter inside a case (esp. for small cases) which could block air flow. 100% of readers found this review helpful.

Nice Power SupplyStrengths: Super quiet, no voltage switch, has 4 SATA connectors, can be used with motherboards that have 20-pin connectors, nicely organized cables, hopefully economical in the long term. Weakness: None that I can think of. I bought this to replace a generic Turbolink LC-A350ATX, and so far I am very happy with this very nice Antec EA-430. Fitted perfectly in my case (XSonic Xtreme II X28-4W) and works flawlessly so far with my older Abit VT7 motherboard. Cables are very nicely organized, with plenty of connectors for a regular user. I cannot say how economical it is thanks to its 80PLUS compliance, but hopefully it will save some energy. 100% of readers found this review helpful. Did you find it helpful or unhelpful? Top

Great Efficient PSStrengths: Efficient, powerful enough for most applications Weakness: none I bought this in my attempt to make an energy effienct gaming machine (an oxymoron, i know). With everything else I assembled, I'm able to run Battlefield 2 with full graphics at ~200W. Idles ~150W. Have had no problems at all with it. Did you find it helpful or unhelpful? Top

Effecient and VERY quiet power supplyStrengths: 80-plus efficiency. Pays for itself over the life of the computer. Quiet. Weakness: None I powered on this with my current Dell PC and the difference was dramatic. This PS is quiet and runs cool. It's also very efficient. Should be able to handle any Quad core CPU with an 8800 GT video card with no issues. Did you find it helpful or unhelpful? Top

Antec Earthwatts EA-430 Power SupplyStrengths: 80Plus, Long Cables, Very Quite Weakness: Not modular You cannot go wrong with this Antec PS. This is my third Antec PS and I feel the best one yet. It is rated 80Plus which will save you money on your electrical bill (something everyone is concened with these days) and Green so it is good for the environment. The cables are long enough to reach evey device in my case. It is very quite which is perfect for my HTPC setup. I wish it was modular so the unused caables/connector do not block air flow but you can't have everything. Did you find it helpful or unhelpful? Top

Outstanding Power Supply from Reliable ManufacturerStrengths: Very quiet; 80PLUS means greater efficiency and lower power costs- cable lines are long enough to reach just about any case Weakness: more expensive than others, but still resonable very quiet power supply that i know will last me years- have had many antec power supplies that have been very reliable Did you find it helpful or unhelpful?

Excellent power supply for the costStrengths: Brand, efficiency rating, cost Weakness: no modular cabling Excellent power supply, very quite, highly efficient with 80 rating and environment friendly. I also found it to relatively light weight compared to my older Antec. I read online that this is originally a sesonic OEM which we all know if one of the best OEM brands. It comes with voltage autodetection but lacks the modular cabling which so important nowadays. Did you find it helpful or unhelpful? Top

Very quiet and stableStrengths: quiet stable efficient good tech support Weakness: no detachable cables only 430w I like this PSU very much. It's very plain-looking -- no fancy pictures or whatever, but works very well. Its internal fan is essentially inaudible, and the power has been very stable. You don't want this for your SLI super-power rig, but you probably DO want it for your HTPC or basic desktop. Did you find it helpful or unhelpful? Top

"Green" Power Supply at a Great PriceStrengths: Rebate, Pro Green, Low Heat, Low Noise, Not That Much More Than Standard Power Supply Weakness: No Sensor Cable, No Cable Sleeve on Every Cable Big believer in the Go Green push. So when I saw this available with a decent rebate, I immediately jumped on it. I was actually very curious how this would compare against my Antec Smart Power 350. The Smart Power, while sufficient for my PC's needs, seemed to be producing too much heat and noise. My knee would sometimes get close to the air out of the Power Supply and it's quiet hot. Installation was a breeze in my Sonata - nothing out of the ordinary. Too bad there isn't a Sensor Cable - no way to truly gauge against my older Power Supply. My PC is an ASUS P4P800 Deluxe with a 500 GB Seagate drive, 2GBs Memory, CD Burner, Hauppauge HVR-1600 and an nVidia 7600GT. Did you find it helpful or unhelpful? Top

Great PSU at reasonable priceStrengths: quiet, stable power supply, little heat, easy to install Weakness: No modular cable leading to a lot of clutter inside the case I replaced the stock PSU from a brand-name computer with this and it worked perfectly with very little noise and stable performance.

Good quality basic power supply.Strengths: Low cost (after rebate), good efficiency for a budget unit, 3-year warranty. Weakness: N/A Has enough power to meet most users needs. Good for slight overclocks and up to about an 8800GT graphics cards. For power users go for more watts. I was surprised that a power supply in this price range was 80 PLUS certified. Has plenty of connectors. Only 1 pci-e connector, but if you plan on running dual 8800GTS cards this probably isn't the ps for you;) Did you find it helpful or unhelpful? Top

Great Power supply at a great price!Strengths: -Price after rebates/deals -Quality Antec stepping up to Seasonic Quality & -Focusing on Power Efficiency is Important -Partially wrapped cables (24 pin main power) Weakness: -Not Modular (can't remove or change cable config) -Not Sexy Looking for a show case -I was planning a new build and so I decided to do some research on Power supplies etcetera. Well I was amazed at how much there is to know about power supplies.- Did you find it helpful or unhelpful? Top

Powerful and stable Power supplyStrengths: very stable, enough cables and ports Weakness: not enough power for SLI system I bought this power supply because of its brand antec. And the fact told me that it is really a worthy buying PS, although it is a little bit expensive than the other brands. It works stably, my computer never got stuck. In addition, this PS has enough long cables and ports so that you can connect every component of your computer in a comfortable way. The potential problem is it is only 430W. If you want to run a SLI system, it might not be your choice. Did you find it helpful or unhelpful? Top

EarthWatts EA-430 430W Power SupplyStrengths: High quality, performs well and uses less power. Weakness: None. I have used several Antec power supplies; they are built solid, work well, and I have never had one shock me, catch fire or damage the equipment it was connected to, like some other brands. I used the EA430 to replace a 500 watt power supply, and it handles the load fine. I did notice that the EA430 is somewhat lighter than the other Antec power supplies I've used, and there is no second fan; but I would guess that this is to reduce the power consumption. It's great that these power supplies are made to be more efficient and have features like active power factor correction. Before Earthwatts, it was difficult to find a power supply that had these features at a reasonable price. Did you find it helpful or unhelpful? Top

EarthWatts EA-430 430W Power SupplyStrengths: quiet easy to install Weakness: none This is a very quiet power supply. So far I don't have any complaint about the sound it made on my machine. The wires come with this power supply are just fit and made it easy to be installed. I strongly recommend this one. Did you find it helpful or unhelpful? Top

Plenty of PowerStrengths: Quiet; Powerful; Affordable; 4 cables for Serial Devices Weakness: 430 watts may not be enough for some users I purchased this because it was advertised to have low power consumption. This was put into a brand new HTPC, so I don't have any basis of comparison as far as energy consumption. However, the unit is quiet, and has plenty of power for my setup. I really liked that it has 4 cables for serial devices. Plus, Antec is a brand that hasn't let me down over years of system builds. Did you find it helpful or unhelpful? Top

Good Litlle Power Supply from AntecStrengths: 1) Does what it needs to do 2) Price 3) Low power consumption (it is named EarthWatts) 4) Quiet Weakness: 1) Could be colored, modular, etc. like high-end power supplies, but not really a problem This is a great power supply that has a lot going for it. It is efficient, quiet, and powerful enough for most applications. There isn't much else that's can be said about a power supply. Of course, it isn't modular or colored, but it gets the job done well at a great price. Recommended. Did you find it helpful or unhelpful? Top

Excellent power supply with low power consumptionStrengths: 1. Low power consumption (tested using a meter) 2. Quiet 3. Long cable length Weakness: 1. No modular cables but I can live w/that I wanted to upgrade the power supply for one of my PC's which is always on. Since power consumption over 24x7x365 turns out to be quite a bit, I wanted a power supply that would complement the low power components of that PC. Did you find it helpful or unhelpful? Top

Great power supply for those on a budget.Strengths: Reasonably priced, highly efficient, simple design, quiet. Weakness: Not modular, would be nice if it had a little more power. The reasons that I would buy this unit again - 1) It is reasonable priced 2) it's one of the quietest power supplies that I've ever owned 3) it saves money over the long haul with reduced electric bills due to it's 80% or better efficiency. It has enough power to handle 95% of the most common PC builds today. Probably not enough for dual video card setups, but certainly sufficient for most other applications. I would say the only area that can be improved upon would be the lack of a modular design. This not a deal breaker, it would just nice to have incorporated. Other than that, I give this unit a solid 4. Did you find it helpful or unhelpful? Top

excellent power supply at an affordable priceStrengths: PCI-e connector, 80% efficient, runs stable, active pfc, quiet Weakness: not sli ready, no modular connections I was in dire need of a power supply for a computer i was building. I stumbled upon this power supply on one of my many searches and i'm glad i did. Its quiet and runs at stable voltages. For the price i got it for, i couldn't pass it up. I would recommend this power supply to anyone who's looking for a great power supply to run their system and at 80% certified efficiency, it'll save you money on your electric bill.

Super solid power supplyStrengths: super energy efficient Weakness: some clustering problems w/ the wires. Very power efficient with enough connectors to power several HDs, CD/DVD drives, high-end graphics cards, sounds cards, etc. Max power output 430W. Overall an excellent buy for the buck.

Solid PSUStrengths: quiet efficient Weakness: somewhat expensive I'm using this power supply in a machine w/ a dual core opteron, and an nvidia 7950gs video card and it's done fine. Judging by the fact that the fan isn't running very loudly at all in this rig, I'd say it is has power to spare. Review have shown this unit to be 80%+ efficiency depending on output, which is probably above average these days. Did you find it helpful or unhelpful? Top

Good PSUStrengths: Relatively quiet. Cheeeap! Not too many watts. Runs all my components stable. Weakness: Not modular. Doesnt have intake fan. From what I hear these psus are rebadged seasonics. At this price point (lest than 40 bucks) they are the best deal I know of. I like that they are highly efficient and high quality. My only grip is that I wish they were modular, and had another intake fan. Due to the lack of intake fan, this psu gets rather hot. I've had no problems with stability thus far, but the heat does worry me. Did you find it helpful or unhelpful? Top

Great Power SupplyStrengths: This power supply is great. Low noise, adequate for most desktops that are not hard core gaming machines, super clean power. Weakness: None that I can think of yet I bought this to replace my antec power supply out of a Sonata case because it failed. This power supply is quieter and more efficient and supplies 430 watts of power (80 watts more than the power supply I replaced). You will not be disappointed with this power supply.

Quiet and works as advertisedStrengths: Quiet, saves the environment, dual 12v rails Weakness: only one pci-e connector Antec's Earthwatts 430 power supply is very quiet, was easy to install into my case, and fired right up with out any problems. As long as you don't have SLI or some monster video card, I would recommend it fully. Comes with 4 SATA connectors and one PCI-E connector. Help save the environment and go get one!

High efficiency quality power supply.Strengths: Uses less power and plenty of connectors. Weakness: Could have been a bit quieter. Less power used means less heat. Less heat is better for your computer. Less power used means costs saving because less electricity is used. The EarthWatts EA-430 power supply by Antec provides all of the above with "80 Plus" certification, which means it will perform at 80% efficiency for a load between 20% to 100%. With 4 SATA, 6 Molex, and a PCI-E connector(s), this power supply has enough hookups for most applications. Using a 120mm fan instead of the 80mm fan they used might have made it a bit quieter, but otherwise this is a solid built power supply. Did you find it helpful or unhelpful? Top

Good PSU so farStrengths: Nice affordable PSU. Plenty of connectors. Very quiet. Weakness: None so far. A solid PSU from Antec. The connectors are plentiful and the wires are long. It is said to be very efficient (though I don't have the proper equipment to test this). The air coming through the device feels cool; this is a good sign that it is not prone to overheating. Most importantly, it is very quiet. I highly recommend this product to anyone in the market for a new power supply. Did you find it helpful or unhelpful? Top

Antec Earthwatts 430W power supply EA-430Strengths: Works well, quiet, easy to install, plenty of cables Weakness: Perhaps not powerful enough for power-hungry ATI video cards, or dual video cards I bought this because it's supposed to be high quality, reliable, and stable, and also because I'm a tree hugger and this PS is supposed to be more energy efficient than most. So far I haven't been disappointed. My new build works really well. This has all of the cables and connections for all new connectors (see specs for details), it's quiet, and it hasn't given me any problems so far. You might want to get the 500W version if you're getting a power hungry ATI video card or need to run dual video cards. I have a 7950GT and the PS has no problems with it.

Quiet, efficient powerStrengths: Very quiet (but not totally silent), good cable lengths, plenty of connectors Weakness: None so far If you want a power supply that will help you save your electric bill and the environment, this is a good choice. The 430W should support most setups that do not include dual PCI-e cards in SLI or Crossfire mode. Did you find it helpful or unhelpful? Top

Good Power SupplyStrengths: Stable voltages, high efficiency Weakness: Weak fan, short cables, basic connectors This is one of the newer Antec power supplies that is built by Seasonic. Just like a seasonic unit, the voltage regulation is excellent, and efficiency is high. Did you find it helpful or unhelpful? Top

Way to go antec!Strengths: High efficiency, basic power-supply; 3-year warranty Weakness: No modular cables This power supply works as advertised. I was replacing an el-cheapo Ultra power-supply that was causing random blue-screens on my system (three SATA hard drives, dvd burner, 8800gts, e6600 cpu). I replaced that 600W supply with this 430W supply, and all problems went away! Antec has a good reputation, and decent customer support. The 3-year warranty is nice, though I hope I never use it! I only wish it had modular cables. Did you find it helpful or unhelpful? Top

Good Basic Power SupplyStrengths: Good value for 430Watts; plenty of cables; 3-year warranty; 80+% efficient Weakness: Cables are not modular I built an "always on" Windows Home Server, using Microsoft's new beta Home Server OS. The computer would contain on-board graphics (which would rarely be used), a DVD-ROM an plenty of hard-drives. I wanted an extremely efficient and quiet power supply, that had good reliability. I had read good things about Antec's EarthWatts model, so gave it a shot. I didn't need alot of power, so selected the 430Watt model. I have been extremly satisfied. The cables were plenty long enough to stretch to the furthest point in my Antec P180B case, and there were enough for my six hard drives (mixed PATA & SATA) and DVD. The fan is extremely quiet, and I barely know the PSU is even on! When I tested the supply before building the computer, all voltages were within advertised tolerances. I would recommend this supply highly for anybody building a basic computer. Did you find it helpful or unhelpful? Top

Quiet, efficient, simple design
Strengths: It's quiet. 80 PLUS certified. It has long cables.
Weakness: Not modular
The 80 PLUS certification means the efficiency rating of 80%+ is at 25%, 50%, and 100% load. Other power supplies that have a high efficiency rating, but are NOT 80 PLUS certified, may only be efficient at 100% load. At 50% the efficiency rating could drop to 70% or lower. Make sure you get an 80 PLUS certified adapter.
The cables were long enough to reach even the furthest of my drives at the very bottom of the case. It's not modular so any cords not used will have to be tied back and put out of the way.
This is a very good power supply and I will buy more in the future.
