Lepa B-Series 850W—The Leopard Attacks
Lepa is a new brand in the computer components industry, currently selling power supplies and peripheral equipment such as external storage (HDD/SSD) cases. For our first look at the company, we'll be torture testing their B850-MA power supply, one of the best products Lepa sells. Enermax has close ties with the company, and the idea behind Lepa is to offer inexpensive solutions and leave Enermax products to focus on the high-end (and higher cost) markets. Let's see what the B850 has to offer and if it can meet our expectations.
The package includes a power cord, four screws to mount the power supply in the case, a user guide, and a 15cm long FDD adapter. A plastic bag protects the power supply from dust and dirt. Noteworthy features include the already mentioned 80 Plus Bronze certification and the separate +12V outputs for the CPU connectors. In addition Lepa offers a 3-year warranty on their PSUs (two years less than Enermax, which is one more area where they can work to reduce the price).
The PSU has four +12V outputs with a maximum current of 20A or 30A. Together these outputs can provide 750W. The combined 180W of the +5V and +3.3V output is quite powerful; most current power supplies use a DC-to-DC converter that can't deliver more than 150 watts. Whether this is good or bad depends on the PC system. +5VSB can handle up to 3A.
The 135mm fan is an RL4Z B1352512H from Globe Fan. This model is used in many power supplies that are manufactured by Sirtec (High Power). With a maximum of 1500RPM it has a moderate speed within the RLXX series, and it can reach a sound pressure level of approximately 29 dBA. However, since the fan output starts at 6V the noise levels are usually not that high. The fan uses 0.33A and consists of 11 fan blades with rough edges.

SanLouBlues - Thursday, December 15, 2011 - linkDid your text to speech eat your words? What does this mean? (Bottom of the first page)
justaviking - Thursday, December 15, 2011 - linkI 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?
JarredWalton - Thursday, December 15, 2011 - linkI'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 - linkHe 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 - linkThat'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 - linkIt'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.
