Internal Design and Components
Like the exterior, the internal design shows some interesting details. They tell us Sirtec (High Power) is the manufacturer of the B-series. There are three thin heatsinks and one large yellow capacitor, which are typical components for Sirtec power supplies. The PCB for the modular ports is isolated by a thin plastic sheet since it's very close to the main PCB. Generally, the power supply case is well filled out. The multi-layer mainboard consists of fiberglass mats and epoxy resin. This also applies to the small PCB with the fan control.
Sirtec uses capacitors from Rubycon (main cap) and Teapo. In addition every output voltage has its own regulation circuit and storage coils. A safety IC from SITI offers OVP, UVP, and 4-channel OCP. The EMI filtering includes all the important components. The X capacitor behind the entrance is isolated as well; note that older Sirtec products didn't have shrink tubings there.

Did your text to speech eat your words? What does this mean? (Bottom of the first page)justaviking - Thursday, December 15, 2011 - link
I was also wondering WHY that comment was made.Are they out of balance?
Are the edges (from plastic injection molding, for example) ragged?
Do they have an uneven finish or surface texture?
And most importantly, is this anything that will affect performance?
Will dust collect on it more than usual, or will it result in more noise, or something like that?

I'll be honest, I edit Martin's articles quite heavily since he's not a native English speaker, and I wasn't quite sure what he was referring to here. Hopefully he can respond with additional information. :-)iamkyle - Thursday, December 15, 2011 - link
He is probably referring to the fact that the blades are indeed poorly shapen, or have rough edges. Globe fans are NOT known for their quality.JarredWalton - Thursday, December 15, 2011 - link
That's sort of what I thought, but I didn't want to read too much into it without personally seeing the fan.Martin Kaffei - Friday, December 16, 2011 - link
It's my fault."Rough edges" would be the correct description.
Thanks a lot for your help.

I put a bottom-mounted PSU with a 50cm Main cable in a popular mid-tower case. That cable would barely reach the mobo connection (near the ouput panel).
People have been complaining for years about these cable lengths, with bottom-mount PSUs. It's amazing that the vendor engineers remain clueless. Of course more wire costs more money, but an extra one or two inches would put this supply on a lot more buyer's short lists. As it is, I have to pass on it.
