SeaSonic SS-400ET 400W Power Supply

Comment:
I bought this p/s for an everyday computer. It performs well and is quiet. I wouldn't use it with a expansive video card, but for an i3 (on board video), one hd and dvd it is perfect.

Using it over an year, actually close to year and half.I used to use it w/ Q6600 and 9800GTX system. Now its working with X3 720 and 9800GT.Its silent, working, Everything seems nice. I even like their seasonic logo. It looks like an old plain PSU, but it does a great job.I can't really complain other than the price. I find $40~50 for a 400W unit is a bit pricey, but its still affordable. I'd rather pay $10 than using something not so reliable.PS. the video uploaded on the top of the page, I think LITEON stopped making any PSUs after like 2006~2007. They used to make some 'OK' PSUs actually... Its just they are quite old and Seasonic SS-400ET is relatively a newer PSU....

A very quiet, over-achieving PSU. For a build with an i5 quad and Radeon 5570 card, more wattage would have been a better choice, but this unit has exceeded expectations. The numbers indicate that two additional devices could still be added. Very pleased!

For the price, this power supply is great. I needed a quality and quiet PSU for an HTPC build and this fit the bill nicely. 400 watts is more than enough for most systems and likewise there is more than enough connectors for even the slightly above average system.

Overall this is the best 450W power supply that I can recommend. Seasonic is an extremely good brand and well known among the enthusiast community.

Comment:
My first Seasonic product, and I'm very happy with it. No problems, and it was quite cheap. Had all the connectors I needed. Used it for a budget build so the colour matched my case interior. Only bad side is it's non-modular, which is expected due to the price. Great product if you're on a budget.

For its price, this is quite a reasonable, and reliable PSU. I would most defintley purchase another should the need arise. This review was modfied by poster @ 08-26-10 02:52 PM

Of all the power supplies I have owned before, this one is quite decent. The fan is quiet but it is by far the loudest component.However, it died in a recent power outage and won't boot up again. If it cannot deal with one or two surges in a year that even a $25 psu can, then it is not worth my time or money.

Comment:
Excellent PS for a basic build. Great price and provides consistent, reliable power. Also very quiet. No complaints.

Comment:
got this to replace an old junked 250W PSU in a junky PC that wouldn't boot, installed this PSU and now i can use my PC again until i build a new one.no complaints so far.

Comment:
Overall this is a great psu for the price. Preferably I would have liked to have better cable management inside my computers, but the price of the modular cable psu was just way too much. Otherwise I could not complain.

Comment:
Runs fine for a budget build comp. No problem with cable lengths since I used a mATX case. Too bad the cables didn't come with sleeves, otherwise it would look a lot less messy in a mATX case.

Works well. However, the first one NCIX shipped me was crushed in shipment by Purolator, along with the corner of the shipment box. NCIX didn't protect it enough. Got an RMA and the new one was slightly crushed as well. The fan grill vibrated against the internal fan. I had to pull it outwards with pliers.

Comment:
This is ample power for a typical desktop build, and plenty quiet with temperature-controlled fan. The only improvement I would recommend is a motherboard fan connector so that a user could monitor the fan speed. Not that it matters if the internal temp control is properly functioning.Excellent value for a budget piece.

Comment:
Why would you buy another equivalent power Seasonic power supply when this OEM version is so reasonably priced? It has a large fan and when I'm running it on my HTPC rig it's next to silent. It has a cage over the fan which is optimal for letting as much air through as possible as quietly as possible. It's also highly efficient, so you can save the world, and has enough power for most basic/mid range systems.

Comment:
When I had my motherboard try to intelligently control the fan, it seems to have this really annoying winding up and down noise. Stopped when I turned the feature off. Hard to tell how well it's functioning since I'm not a techie. This review was modfied by poster @ 01-07-09 07:42 PM

This is a great PSI'm running a slightly clocked GeForce 9800GT and a Core2 Duo 3.0Ghz, 2GB of RAM and a PQ5L Pro MBWorks great.

Comment:
Great PS for the price. Installed into an older PC upgrade with older devices (IDE, PCI/AGP) and performs perfectly. Very quiet operation too.

Comment:
This is great when you want to make a cheap build but still have a reliable good quality PSU without spending big dollars on it. Just make sure you have a power cord or grab one on ncix for like 2$. Forget sli/crossfire on this there's only 1 pci-e connector.

I picked up this Seasonic 400 watt with a crucial ballistik ram combo. You cant beat the price!! for 85% of the System builders out there this will run anything you need it to with the exception of SLI and high end gaming cards requiring more power. Seasonic is a reputable brand which will power your system troble free. Has a 120mm fan to help keep the unit cool and isnt lightweight like so many generic psu's. Bang for the buck, Seasonic gets my vote!!!
