300W to 450W: 20 Power Supplies on the Test Bench

HEC HEC-350TE-2WX 350W
HEC (or COMPUCASE) has been making power supplies and other products for quite a while now. We have to admit that we never liked anything from the company to date because we have seen mostly passive PFC topologies when active PFC was being utilized by the competition for some time. You can say HEC is conservative with everything they do, as the designs and limited number of retail products suggests. In fact, we always wanted to get retail models from HEC and we were promised them in the past, but they never arrived in our labs. This is why we also acquired this unit from friends rather than HEC itself. It comes in grey and sports two 12V rails with 14A each and a combined power of 276W. It is cooled by a 120mm fan.
Looking inside of this unit shows a similar heatsink design to what we saw in the FSP units. This time they look somewhat massive and at least have the slightest touch of fins. The lack of a large coil suggests active PFC, which makes this unit the first one we have seen from HEC without passive PFC. All the capacitors are made by Teapo and the fan comes from Young Lin Tech.
With HEC we have the same problem as we have seen with the OEM model of FSP. The cables are so short that we can't actually see them being usable in anything other than small Micro ATX chassis. The length of the 24-pin and 4-pin connectors of just 30cm is too short for anything else.

That is a heck of a lot of work for this article and we appreciate it immensely! Between this article and the upcoming mid-range builders guide (I'm begging...please get it out asap) you have reaffirmed for me this is the #1 site.Thanks again.

The breakdown of the cable connectors and the build quality descriptions were helpful. The power noise charts look useful as well.mino - Monday, January 12, 2009 - link
Copy that, one of the best PSU roundups around.magreen - Wednesday, December 31, 2008 - link
We definitely appreciate the roundup. It addresses our needs as consumers. I wish you'd add more info about the Antec Earthwatts 430 though... it's one of the most popular PSUs on the forums here and always shows up for cheap in the hot deals section, often bundled with an Antec case. Wish you'd give us more details on its efficiency, ripple, and your overall take. I don't think you actually said anything about its performance at all. Thanks!OddJensen - Monday, January 5, 2009 - link
Isn't there a Delta made version of the 430 as well?Christoph Katzer - Monday, January 5, 2009 - link
Yes which we didn't have.Christoph Katzer - Wednesday, December 31, 2008 - link

Thanks for this article. I am one of those who does modest OCing and no SLI, and this article was pertinent for me.eetnoyer - Wednesday, December 31, 2008 - link
No temperatures at load? I would think that temps at 100% load for each unit shouldn't be too much. Just as a worst-case thing.
