1 out of 5 eggsLasted 5 months

Pros: When it worked it was quiet and efficient.

Cons: I had always heard that Seasonic made the best power supplies, so when I wanted to replace a generic media center power supply that came with the HTPC case, I figured it was the perfect time to try a lower-end, inexpensive Seasonic power supply. Unfortunately, this Seasonic power supply only lasted from the delivery/installation date of 03MAR2014 until today, 08JUL2014, when I noticed the living room media center was not powered on. Hooked up a power supply tester to it and no beeps or anything, that's how dead it was. So, I had to put in the generic old Apevia Turbolink power supply that came with the media center case. Oddly enough, that super generic power supply still works fine after 3 years.

Manufacturer Response:

Hi Dave, I apologies for the inconvenience. Please visit www.seasonicusa.com and we will try to resolve your issue as soon as possible. Thank you.

5 out of 5 eggsQuality Mid-Priced Selection

Pros: After a power surge smoked my low-priced power supply of another brand, I decided I needed to spend a little more money to get a brand I have almost standardized on because of high quality - Seasonic. I was pleased to see a variety of power output models available - all rated highly. I was shooting for 400W, so this filled the bill. I was repairing an old computer, so the mix of Molex and SATA cables came in handy (I had carefully looked at the product picture to assure this availability). Installation was a snap (being OEM, you get a lower price in return for using your old power cord and screws), and the old unit fired right up, stable as a rock (the aging power supply this replaced was causing random reboots and USB port problems).

Cons: None. This unit came up on line routinely, just what you want. Just plenty of stable power.

Other Thoughts: If you are getting mysterious reboots from "random" causes, be sure to think about checking out the power supply. A new one is well worth the investment!

5 out of 5 eggsGreat power supply, no frills

Pros: - High efficiency
- Plenty of adapters
- Silent fan

Cons: - I didn't use any of the molex adapters, so that was a bit of a waste. Molex seems to be becoming more legacy, as SATA power and the 8-pin and 6-pin ports are powering most peripherals/add-ons.

5 out of 5 eggsfantastic

Pros: great inexpensive power supply, in my honest opinion unless you need a modular power supply this is the best psu for the money in this price range. I have a dozen of these in service right now.

Cons: none, just be aware that this does not include mounting screws or a power cord.

5 out of 5 eggsA really good power supply

Pros: Installs easily, works like a charm. Good old-fashioned design and wiring appeals greatly to me - I'm tired of all these tightly sleeved and dark-colored PS units (it's nice to see something designed for us old-fashioned computer fans).

Cons: OEM unit, so no box, power cable, or screws; that's fine though, I have plenty of those around.

Other Thoughts: A great replacement for my old Pentium 4 Northwood build, now configured as a Win9x retro-gaming computer. All hail Seasonic!

5 out of 5 eggsReally Good PS

Pros: Very good well built and heavy power supply for not a lot of cash.

Cons: no sheath on wiring - could use one where it exits the case

Other Thoughts: definitely like Seasonic power supplies

5 out of 5 eggs

Pros: Great power supply for a great price.

Cons: Because this is an OEM product, you will not receive mounting screws or a power cord, but most people should have these things lying around anyway.

5 out of 5 eggsAnother good one

Pros: Well-made, efficient, runs cool and quiet (quieter than the case fans, anyway)

Cons: Sleeveless cables, and virtually no online documentation -- minor annoyances

Other Thoughts: This is a new 80-Plus Bronze version of the SS-400ET 80-Plus (no Bronze) model from five or more years ago. Apart from the small efficiency increase, the stats are the same. Its eight cables, measured from the back of the PSU to the back of each connector, are:

ATX12V 24-pin (mobo): 22" (55.9 cm)
EPS12V 8-pin (CPU): 21.7" (55 cm)
ATX12V 4-pin (CPU): 21.7" (55 cm)
SATA power: 19" and 25" (48.2 cm and 63.4 cm)
SATA power: 19" and 25" (48.2 cm and 63.4 cm)
Molex 4-pin: 12.75", 18", and 23" (32.4 cm, 45.6 cm, and 58.4 cm)
Molex 4-pin/floppy: 19" and 24" (48.2 cm and 61 cm) -- the end one is the floppy drive connector
PCIe graphics 6-pin: 22.8" (58 cm)

I'm using it to run an ASRock Z87M PRO4 microATX motherboard, 65W Core i5 CPU, Radeon HD 7850 graphics card, 8GB of DDR3 SDRAM, 7200 rpm HDD, SSD, and CD/DVD burner, plus the case's three fans. No problems. Whatever their shortcomings in the documentation department, SeaSonic continues to make quality mid- to low-watt PSUs.
