The Seasonic X-Series of SFF PSUs?

post #1 of 11
Thread Starter 
As per the title: what is/are the Seasonic X-Series of bite-sized power supplies?

The primary intended application is HTPC use. Silence and small size are requirements, as is high efficiency. A secondary application would be in a SG05- / Shuttle-sized gaming-on-the-go machine (likely powering a mildly overclocked Sandy Bridge chip plus a single GTX 560 ti, overclocked 460, or similar).

How the heck did I forget Kingwin...

All of those are full-sized ATX power supplies. This makes them too big for my uses.

You want mATX?

In that area there really isn't anything. So get a bigger case?

An ATX-sized PSU is not an option, nor is a larger case. I know what PSUs I'm using for those.

My target size is SFX or similar. The 450W from Silverstone looks like the only viable option for now. Shuttle has a 500W supply that looks interesting but I'm still trying to find reviews for it.

Just get the Silverstone 450w. It's a good unit that will serve you well.

Seeing that some people are putting an i5 670 up to 4.8GHz and still feeding a 480 at 800MHz using the Silverstone 450W, I can't find any reason not to get it. I expect it'll handle a more efficient Sandy Bridge chip and 560 ti even easier, overclocked or not. The Shuttle PSU looks nice but I can't find good review sites and being as it's made for Shuttle builds I'm not sure it can easily work with anything but shuttle parts (may not be a bad thing if the parts are up to the task of SFF gaming or, failing that, HTPC use).

You can honestly never go wrong with a Seasonic
post #9 of 11
Thread Starter 
Does anybody have or know where I can find pictures of the inside of an ST45SF power supply? I need to see if I can replace the 80mm fan (broadly agreed on as the noisiest part of the PSU), and it looks like I might be able to sneak a better/quieter 92mm fan in there.

Seasonic has a faithful customer in me for ATX power supplies. Do they make SFX-sized power supplies that are better than the Silverstones?

This review has pics of inside

Note that the fan needs to be 12mm thick, not the normal 25mm. TBH if you are going to put a high end graphics card in there, the graphics card will be noisier than the PSU fan.

Seasonic makes a 300W and 350W SFX PSUs. The 300W has a protruding fan (old school style SFX). The 350W uses a 60mm fan which can be audible, if you care about noise.

BTW FSP makes the Silverstone PSUs. They are also sold under the FSP brand in 400W and 450W versions.
