Internals Continued



The two coils on the right of the primary side are actually mounted on small PCBs and not directly on the main PCB. There is a heat conducting tape between the coils and the heatsink behind them to transfer the generated heat from the coil directly to the heatsink. The larger PCB on the left side contains the PFC control.



The main capacitor is rated at 105°C, which is obviously necessary since there is no fan to cool this part down. The capacitor comes from Panasonic rated at 470µF with 450V.



Things look quite cramped in this design, although with a lack of airflow all of the extra heatsinks and heat transfer surfaces make sense. The idea is to get all the heat conducting to external surfaces that should have some airflow from the rest of the system.





The secondary side features some Teapo and Ostor capacitors, all rated at 105° again since it will be somewhat hot inside the PSU.

    Their Zen 300w power supply costs around $75, although expect to have more issues with them than their 12cm fan ones.

    Every so often, I wish someone would review POS power supplies. Just to see what they would do, and how easy they can destroy motherboards.

    If you are building HTPC and pick right components you can get away with fanless setup. I did just that for my HTPC setup and it wasn't a rocket science.

    I got Antec NKS2480 case with FSP Zen Fanless 400 watt PSU, Ninja Mini for CPU cooler and that's it! throw in hard drive and optical drive and you are all set. Antec case does come with 2x120mm fans that you can use, but it's not necessary.

    My HTPC is on 24x7 and temps are as reported by SmartFan during movie watching. (idle temps are even lower)

    Temp 1 38
    Temp 2 38
    Core 15C

    Power consumption as reported by Kill A Watt:
    Boot up 60-88 watt
    Idle 65 watt
    Non HD Movie 67 watt

    I guess I forgot to mention I use Gigabyte 780g mobo with AMD 2400 (45 watt) Reply

    Why are PSU makers still including more Molex connectors than SATA? Now that the optical drives have finally gotten their act together and moved to SATA, the need for Molex is primarily legacy devices. Would be nice if the PSU reflected this and flipped the ratio of connector types to support SATA. Reply

    I have a lot of fans in my system, and exhausted my supply of fan mobo headers. Having a lot of molex connectors from the psu really helped out.
    Of course this situation doesn't mean a lot when we're talking about components designed for silence. But also consider that lots of people building a system just migrate optical drives from an old box. Not to mention that I needed to use pata optical drives in order to free up more sata ports, which are all in use now.
    Molex is still king. In fact most people using sata just have a single sata hdd -- there isn't a huge market for having lots of sata power connectors. If you really have that many sata devices, you probably need a bigger psu than this one anyway.

    I agree... sometimes there are still even more Molex than Sata connectors. I bought my first Sata DVD drive just a week ago, maybe there are still too many people with old stuff like me. Reply

    The case it comes in appears to have better build quality than the PSU itself Reply
  • Super Nade - Wednesday, April 2, 2008 - link

    It is better built than the FSP Epsilon and seems to be based on a different platform. The OEM is FSP (both the UL and the SPI on the transformers point to this). Reply

    I am mostly talking about the exterior appearance. I figured it was FSP just based on the way they broke down the label. Reply
