1 out of 5 eggsdead after testing

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: brand new

Cons: Was testing it with a power supply tester, after preparing to test a different set of cords it wouldn't turn on at all. No smoke but definitely should've failed quality control

Other Thoughts: definitely worth having a power supply tester, I recommend the thermaltake doctor power 2.

2 out of 5 eggsDamaged Model

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Relatively cheap, and perfectly sized for the case.

Cons: Outside of the few pros, this PSU has been nothing but issues thus far. While I'm hardly the most technologically experienced, this is the fourth computer rig I've built from scratch. Thus far, the issues have been all over the place upon arrival. Cabling had frayed around the motherboard's PSU plug, a small ticket that voided the warranty had already been partially peeled, and it relatively worked. As I've mentioned, this is the fourth rig I've built and this one was designed for a good friend of mine. Upon arrival, I quickly assembled the PC and got it in working order. Started up the computer and installed a fresh OS upon his HDD, only for the issues to start here. Despite being in the proper wattage range, the GPU was improperly powered. It would come on and off at relatively random times. Of course, I imagined it was the GPU damaged on arrival and initially notched it up to that. However, after installing the GPU into not only my rig but also my roommate's computer, it worked without a hitch even when playing video games. Now curious, I remounted the GPU into my friend's motherboard and completely rewired the PSU just in case I had messed something up.

Initially powered on and started boot up, but once again the GPU began to randomly turn off. After awhile, I noticed a few of the additional accessories such as keyboard and headset would die on occasion as power seemingly failed.

So far?

I plan on returning this PSU and getting it replaced with a new one. I hope the new one will perform better and I'll be able to post a better review soon.

Manufacturer Response:

Hi Cameron, Normally speaking, if the PSU fails, then it will fail completley and not in a random way. As well, if the keyboard and headset would turn off as you have mentioned, then this might most likely be a MB issue because the keyboard and headset is connected to and powered by the MB and not directly by the PSU. If you have any issues, please contact newegg@seasonicus.com. Thank you.

5 out of 5 eggs2nd time lucky

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: Stable voltages
Sturdy construction
Japanese capacitors
Good cable lengths
Perfect size for most systems with a single GPU
48 Amps on the 12V rail
Quiet, with a ball bearing fan - should last a while
5 year warranty

Cons: First one was badly damaged

Other Thoughts: I've only had mine two months but I love this PSU! It is solidly constructed and just has the weight of a quality build. I chose the non-modular one to save a few bucks and have no regrets. If you want modular, spend more and buy modular. Yes there are a LOT of cables to deal with especially if you are only running a single GPU. However if you have a case with good cable management options then you just need to be creative. After all, once you install it, how often will you need to access all the cables? Even with upgrades it's not often enough that it's a hassle.

I don't deduct eggs for what is probably a packaging problem or shipping damage on the first one. Note to Neweg though: you absolutely have to look at how you package these for shipping. Both arrived in a shipping box not much bigger than the actual PSU with only two sets of those plastic air pillows that Newegg uses - completely deflated!! The first PSU was actually dented at the back with the top pushed up. To actually incur that kind of damage on such a solid PSU speaks to how poorly it was packaged for shipping - no reflection at all on a quality product from Seasonic. And to others, please don't let your ratings reflect these kinds of issues. This is an issue with Newegg. Newegg did replace promptly though, so it was more an issue of inconvenience for me.

1 out of 5 eggsBANG!

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: It worked for 30 days.

Cons: It worked for 30 days. Blew a capacitor powering an i7 2600 and single GTX 760.

Other Thoughts: Now I have to pay to send it to Seasonic and wait even longer for a replacement, and then worry about the replacement blowing up all the time. I should have spent more on a better unit. Now I've lost time and money, plus put my system at risk of serious damage.

Manufacturer Response:

Hi Philip, Sorry for the issue, is your case now resolved? Can you please let us know your system configuration? The power supply has all the necessary safety and protection features to ensure that your system will not be damaged due to the failure of the power supply. Please write to us at newegg@seasonicus.com and let us know if everything is now resovled. Thank you.

5 out of 5 eggsSeasonic is and always will be the best

This review is from: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Pros: I won't use another brand, unless it is a rebranded Seasonic unit! Why do you think Corsair and others use Seasonic? Let's see...rock solid reliability, silence, and longevity. Oh, and the highest quality components.

This particular unit is not modular, but has nice long cables for a typical mid tower. It is not a octopus like some other units, but be prepared to use plenty of zip ties. Cables are nicely sleeved. I could not hear the fan. Bronze Certified (not that important to me...rail stability and ripple ARE).

Cons: If I had any, I doubt I would have bought a Seasonic. The lack of cons is why I won't buy anything else.

Other Thoughts: No, they are not cheap. BUT, you can skimp on the PSU and then sign yourself up to buy a new mobo, video card, and CPU when your nasty no-name PSU fizzes on you....
