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.

I had to buy a 4" 4+4pin to 4+4pin extender for my power supply when I bought a new case with a bottom mount. Fortunately I can route that cable behind the motherboard tray so you never see it.JonnyDough - Thursday, December 15, 2011 - link
Enermax Liberty PSUs die right after the 3 year mark, almost within a month of each other....I'll be sticking with higher end PSUs, and going for the 80+ gold. For the money, they are well worth it.

Others will disagree, and I don't blame them; you could spend double the amount on a high end 850W PSU. Three times the $80 figure.However, when I'm building a rig that requires I use a PSU with this much capacity to supply power, I'm not looking to save money as my first priority; I'm looking to supply the highest quality power to components I'm going to push hard through overclocking. I'm looking to install 2 (at least) high end video cards. My philosophy is that it's worth another $100-$150 to have the best available in that situation.
For a build that's never going to see parts pushed hard and doesn't require more than 600W, I can certainly see saving some money with a budget PSU you have read a decent review of .
I give Lepa large amounts of credit though for producing a PSU that will be attractively priced to builders that may not know better than to judge by anything but price, and still give them a decent PSU. Every good one helps put the bad ones out of business.
