5 out of 5 eggsQuite Fan, only comes with 4pin ATX plug

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: As advertised. The Fan is very quite. Good power efficiency.

Cons: Not really a problem, I was a little surprised that it only comes with one 4-pin ATX CPU plug. (Normally, you get a 24pin ATX and two 4-pin ATX plugs). This only matters if you are running a power hungry CPU. Which you probably would have bought a bigger PS anyways.

Other Thoughts: As mentioned, this is a 300W PS which comes with a single 4-pin ATX CPU connector. I am using this on a Intel low power 65W CPU, so it works great for me. If you are running a bigger CPU, this will not work for you.

5 out of 5 eggsGood Basic Use Power Supply

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: Simple, quality construction and 80 plus bronze, I trust SeaSonic.

Cons: Black would have been nicer for the color but at this price I'm being picky.

Other Thoughts: Doesn't include a power cord for connecting to the wall, not a complaint I'm just mentioning it for people who don't know what oem means. I used this for a basic computer for my mom has plenty of power for that and it was a good value. Ignore any reviews that complain about them not including a power cord for connecting it to the wall outlet, they either didn't properly read the description or don't know what oem means.

5 out of 5 eggsGood HTPC PSU

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: Turns on and off appropriately.

Cons: You can hear it a (very) little bit when there isn't much going on in the background. It's not an issue if a video is playing.

5 out of 5 eggsUpdate !!!!

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: Attention !!!! Apparently some new PSU's have fans that don't necessarily kick on just because the unit is powered om !!!! I RMA-ed 1 of these for that reason, got the replacement, & same thing happened. I hooked up a PSU tester & it said AOK !!!! Be alert to this if you are a rube builder such as myself :-/ ....

Cons: none so far ....

Other Thoughts: This was/is news to me, I thought I was snakebit nuying PSU's this year, but apparently not .... Live & learn ....

5 out of 5 eggsThat will do

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: Bronze certified. Low noise and very well built. System only pulls bout 130w from wall, makes this unit operate near its most efficiency.

Cons: None that stand out or are worth writing on a unit of this price point.

Other Thoughts: very useful for systems that run dual/quads with a storage drive or two and integrated graphics.

4 out of 5 eggsGood little PSU. but one thing wrong

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: came in fast. works well.all the cables were good length
only thing i was a little irked with was the sata cables. never had a cable go in one way and have the second sata be completely upside down. in the system i build i had to use the other cable for the HDD instead of using just one for all of it. nothing to knock an egg of thats below

Cons: the main reason im knocking an egg off is because the psu DOES not come with a power cable.
i built pc fora client and i was unaware this psu didnt come with a power cable so when put the build together it made me look bad because now i have to make her wait longer to get a working computer just because of One cable.

that makes me look bad .

4 out of 5 eggsGreat *replacement* PSU

This review is from: SeaSonic SS-300ET Bronze 300W ATX12V V2.3 80 PLUS BRONZE Certified Active PFC SeaSonic USA SS-300ET Bronze Power Supply

Pros: Solid, high quality, really quiet at low (100W max) usage

Cons: Knocked off an egg because this is best as a *replacement* PSU. What arrived was just the PSU. No screws to bolt it to a case. No power cord to connect it to the wall. If you've built a ton of boxes, you have screws/cords to spare.

But, if you're building a very first computer, I recommend a different model that comes with all the parts.

Other Thoughts: n/a
