Hi all, for 2 years my HTPC has been running with a 300w power supply.It has never skipped a beat but I want to upgrade the psu before the smoke comes out of it, and my ssd etc etc.My problem is it is very hard to find a TFX/small form factor psu. I really want one 400w or over. I don't want to change my inwin case as it fits perfectly inside an old radiogram. Any suggestions?? Or am I screwed? Thanks again!

You're probably going to have to import one. About 18 months ago I got a fanless 1U ATX power supply from http://atxpowersupplies.com/ because I couldn't find anything suitable in NZ, and 3D printed a bracket to fit my case. I've checked, they don't list a 400W TFX, but they may be able to source one.

There are some listed on Amazon, so that may be a good starting point for feedback and possible models. (Link to PSU with bad feedback removed)

Will the case take SFX PSU's?

If so, Silverstone makes SFX units up to 650W

Why do you need 400w? My small form factor HTPC runs cool with a 150w PSU.

Wow thats tiny! What processor do you have? I have Ivy I5. I used power calculator and figured out that I am using approx 80% of my wattage. I have a fairly new SSD boot drive and I dont want my PSU to fry it!

I have two small form factor servers - both have been running reliably, cool and quiet for more than a year.
Both are using 80plus micro ATX power supplies supplied with the cases.

"BIG BROTHER" (300 watt PSU)

Intel i3 Sandy Bridge CPU, standard cooling
6 x 6TB WD red HDDs + 40GB SSD for the OS
Rocket RAID card <<<  RAID card set to stagger start-up of the HDDs and reduce switch-on surge

"LITTLE BROTHER" HTPC (150 watt PSU)

Intel Haswell i5 with standard cooling  (runs at 30 degrees C)
2 x SSD drives
no graphics card

Unfortunately < 300w isn't always an option depending on the case form factor. I couldn't find an SFX PSU locally that was < 300w, and the Silverstone 450w was the smallest modular option.

Thanks for the info sideface. That's an awesome server setup. That's my next project. I have now a brand new in win 80plus 300w to keep me going until I find a SFX unit (if I can). Thank you all for your input!
