When running the power supplies at full load, the fan on the exoticpc version speeds up considerably. When speaking full load, I'm talking about maxing out 300 watts on a 300 watt power supply inside the case of a running PC. This is when the noise difference is somewhat more obvious between the two versions. How much of a difference? We're talking the difference between the 300w Nexus and 300w Zalman...not that much. Basically, it's noticeable but it won't kill you. Now you might be wondering about the temperature inside the case. It's almost identical between the power supplies in idle or under full load. The exoticpc one makes similar noise to the Nexus power supply, the silenx one, a notch below the Verax. That's my personal analysis of these two PSUs.
I'm really disappointed to hear this report. As mentioned in the long review thread http://forums.silentpcreview.com/viewto ... 5&start=50
I attempted to order from SilenX.com but wound up ordering a 400W <14dBA SilenX PS from ExoticPC. Seems Peter forgot to change the contact phone number when he set up his new site...and ExoticPC didn't exactly clarify the situation on the phone when asked if I was ordering from SilenX (I've explained more fully in the above thread). Seems another forum member had the same experience as I did.
Never-the-less, the order was placed before I realized I'd been just a tiny bit mislead (it was what folks on the phone wouldn't say, more so than what was said). But with later assurances from Mr. Yu of ExoticPC (via his post in the above same thread) that it would be the exact same PS as that sold by Peter at SilenX, I felt that things would be just fine. But now, unless something has changed with the latest units at ExoticPC, it appears this is not the case.
Just as with Digitalix's unit, mine did not come with a power cord either…which for my situation is not really a concern. But Digitalix does raise a good point considering the price of the unit. However, it did come with the Ahnix SilenX fan and, more importantly, it is almost dead silent when running...under no load at least. I haven't yet had a chance to pop it into a working PC, and may not get a chance to do so for another couple of weeks (waiting for other parts and some free time to finish my build).
Actually, the noise differential running under a completely full load as Digitalix described doesn't concern me that much. I seriously doubt that I'll encounter such cases very often in the normal course of running my PC. What does bother me, however, is the description of the sloppy soldering on the ExoticPC units. I haven't (yet) popped the hood on the unit to check, but if true, that does concern me. It tells me the quality build and workmanship I paid top dollar for has not been delivered. Oh, I'm sure it will most likely give me fine quiet service...and will hopefully be free of problems for a long time to come...but it's just the principal of the thing more than anything else.
I don't build PCs for resale like Digitalix does, so in the grand scheme of things, this whole thing is not really all that big of an issue for me (at least not so far). Annoying yes...but not a showstopper.
However, I did think it was important to mention my experience to others. The bottom line is, based on Digitalix's report, if the differences between the two units is important to you, it would be highly advisable to be dead certain you've been connected to Peter's new company before ordering.
