Introduction

Sea Sonic Electronics announces its launch of the S12II "Bronze" Series - the updated version of the award-winning S12II Series - to meet the growing demand for highly efficient and competitively-priced power supplies.

S12II Bronze The S12II Bronze Series achieves the 80 PLUS® Bronze standard of at least 82%, 85% and 82% power usage efficiency at 20%, 50% and 100% operating loads respectively. This, combined with Active Power Factor Correction, enables the S12II Bronze to reduce energy waste, boost power efficiency, and more importantly, reduce the energy costs for the users.

In addition to the efficiency upgrade, the S12II Bronze Series maintains the strong foundations of the S12II series. Important features such as the stable and proven Double Forward Converter circuit design, the industry-leading Smart and Silent Fan Control (S2FC) and the use of high-reliability Japanese brand capacitors, are all carried forward to the "Bronze" Series.

The S12II Bronze Series, similar to its predecessors, is available in the standard ATX Form Factor and in wattages that are most common for a PC system. In addition to the all-in-one cabling design, the 520W and 620W models come with additional EPS connectors for IPC and server systems and supports both 6P and 8P PCI-E connectors for the most current and high end dual graphic cards.

5 out of 5 eggsExtremely quiet

Pros: Like all Seasonics I've ever owned, it is wonderfully quiet.

The SATA power connectors are in 2 strings of 4 connectors each. Perfect for my 4-drive main bay, and the other string for my 5th drive mounted next to my optical drive. (my optical drive is so old that it's MOLEX/IDE, not sata power, but w/e).

Cons: Higher capacity than I needed. A 300W would have been enough, but I wanted one with lots of SATA connectors. Seasonic's 300 and 350 units that newegg carries only have what looks like 4 SATA power connectors, all on the same chain.

(I have a low-power GPU, and a CPU that isn't too thirsty either, but I'm turning my machine into an IO monster with 5 hard drives for now.)

This PS isn't explicity certified to work with Haswell's deepest power-save idle state, but from what I read, you should be fine to enable that in the BIOS anyway due to other loads on the 12V rail.

Other Thoughts: Not modular, so the cables take up more space. Dunno if modular was an option in this capacity range, but it wasn't something I wanted to pay for anyway. Not listing this under cons, because I wouldn't have paid more for modular.

5 out of 5 eggsAwesome PSU!!

Pros: Very quiet PSU with good stable voltages. Powers everything nicely.

Cons: None

Other Thoughts: This is my first Seasonic PSU and Seasonic is supposedly a reputable so I thought I would try them out and see how well they are.

5 out of 5 eggs

Pros: I've had this PSU installed in my desktop PC which doubles as a home file server for just over a year now. Computer is powered on 24/7 and I have had zero issues. This power supply had all of the connections that I needed and it just looks and feels like it is high quality.

Cons: Wish it is was modular so I could ditch a couple of the unused molex cables but I knew that going into it.

Other Thoughts: Love this PSU and will probably lean towards Seasonic PSU's for future builds as well.

2 out of 5 eggs2 failures inside of 2 weeks

Pros: Sturdy. Looks nice.

Cons: Had 2 of them fail inside of 2 days -- the second one didn't last 2 hours. Brand new PSUs powering brand new hardware. And it was Ivy-bridge, not Haswell.

Other Thoughts: Seasonic is a renowned brand in the PSU industry that are recognized as being head-and-shoulders above their similarly priced competitors. I've gone through 12-15 SS-300/350/400ET for all of the new systems and PSU replacements here at my office. Not a single failure -- some are still going strong after years. Really not sure why these 2 particular units failed, they were both S12II 430Bs b/c Newegg didn't have the SS-300ETs in stock at the time.

They were powering a fairly typical run-of-the-mill business system(s) (19 systems like this total):
ASUS P8H77-M/CSM or P8Q77-M/CSM
Intel Core-i5 3570K
8GB (2x4) Corsair Dominator Platinum 1600 1.5V
Samsung 840PRO 128GB
Western DIgital Black 500GB
Plextor PX-891SAW or PX-L890SA
Fractal Design Core 1000

4 out of 5 eggs

Pros: -decent sleeving
-great performance
-most power cables are nice and long

Cons: -short 8-pin connector (and 4 pin if you use that instead)
-non-modular (you should know this going into the purchase)

Other Thoughts: Great power supply to work with. Sleeving wasn't extremely stiff so it was easy to get cables to bend to your will. The 8-pin and 4-pin CPU cables are fairly short, unfortunately. I was doing a build in my friend's Phantom 410 and it can barely reach the 8-pin on the AsRock Z97 Pro4 (8-pin on this is right above the top left LGA1150 heatsink mounting hole). Also doesn't come with zip ties but that's not really something to complain about.

1 out of 5 eggsNot what I was hoping for.

Pros: Looked nice, had good reviews.

Cons: Failed after two months

Manufacturer Response:

Hi, very sorry for the failed unit, have you contacted Seasonic USA for RMA service? Is everything now ok? Please send mail to newegg@seasonicus.com thank you.

4 out of 5 eggsBest PSU Ever!

Pros: Very low "Ripple" rate, excellent A\C - D\C conversion.

Extremely tight regulation on the 12V - rails

Cons: Fan is not the best in the market, like Sanyko Denki

The fan Makes a "Tapping" noise much like a person's finger-nail tapping a wooden desk

I would attribute this to the possibility of a poor and inadequate lubrication of the ball bearings with-in the fan.

This only occurred after 48 hours of constant use of the PC.

Specifications:

i5 3470-S

Saber-tooth Z77

Corsair Venegance 1600MHZ DDR-3 memory/ram

Asus Nvidia 520 GT "Silent" GPU (uses passive heat-sink)

Other Thoughts: An over all decently performing PSU, compared to the competition!

Perhaps even more so, than the supposed "OEM" market that *MOST* OEM'ed branded companies use sea-sonic components with i.e. (corsair, silver-stone, etc)

Think of it like having an Jaguar,Porsche or any other "hot-rod super-car" engine, licensed to be made in other cars, only with those specific vendors making their own tweaks and modifications done by slightly less brilliant engineers .

meaning that it will work, and *MOST* End-users won't see any difference , except for the most seasoned Enthusiast who brings out their equipment , not just volt-o-meters/kill-a-watt's but sine wave frequency monitors/other snazzy equipement as well

it's basically like the difference between using a "stock" cpu cooler and using a water-block.

Get's the job done, but has no fancy bells or whistles and also, *Theoretically* your computer may last a bit longer if both a "sea-sonic" PSU and a water-block was used in your system, specifically for the reasons of cleaner electric current/conversion (PSU) and cooler Temperatures (Water-block)
