A Look Inside & Component Analysis

Before reading this page, we strongly suggest a look at this article, which will help you understand the internal components of a PSU much better. Our main tool for the disassembly of the PSU is a Thermaltronics TMT-9000S soldering and rework station. It is of extreme quality and is equipped with a matching de-soldering gun. With such equipment in hand, breaking apart every PSU is like a walk in the park!

All Titanium platforms we have come across so far utilize a bridgeless design since significant energy losses occur on bridge rectifiers because they use diodes, a source of voltage drops. Andyson, however, managed Titanium efficiency with a less modern design that uses normal bridge rectifiers and a half-bridge topology that is backed by a resonant converter in the primary side. The resonant controller plays an integral part in terms of efficiency since it minimizes switching losses. The secondary side obviously uses a synchronous design and two small DC-DC converters for the minor rails. The quality of all components is high since Infineon fets and electrolytic caps by Chemi-Con and polymer caps by Teapo were used.

The first part of the EMI filter includes a single X and four Y caps, while the second part consists of two X and two Y caps, two CM chokes, and an MOV, which makes for a complete EMI filter.

Two GBU15L06s are the bridge rectifiers. These have enough power to easily meet the N700's needs.

The APFC converter uses a pair of Infineon IPP50R140CP fets and a single CREE C3D10060A boost diode. Two Chemi-Cons (420 V, 330 uF each or 660 uF combined, 105°C, KMR) are the bulk caps, and it is nice to see a rating above 400 V on these since the APFC's DC bus is around 380VDC strong, as it is a bad idea to have bulk caps that are just about as strong.

The main switchers are two Infineon IPP50R140CP arranged in a half-bridge topology.

The APFC controller is installed on a small daughter-board, and it is most likely a Champion CM6502S capable of providing more than 90% efficiency, while the resonant controller is a CM6901 IC. The latter is installed on the solder side of the main PCB.

The +12 V rail is rectified by eight Infineon BSC010N04LSI fets in the secondary side, installed onto the PCB's solder side and passively cooled by the PSU's enclosure. The two DC-DC converters that generate the minor rails use two Anpec 7073 PWM controllers and two CSD86350Q5D power blocks with, each, two incorporated fets.

All electrolytic capacitors in the secondary side are provided by Chemi-Con and are rated at up to 105°C. We also found a few polymer caps by Teapo.

The standby PWM controller is a Sanken STR-A6069H, while the 5VSB rail is rectified by a single PFR20V45CT SBR.

The modular board is very small and has a few polymer caps for some extra ripple filtering.

Soldering quality is good overall. Andyson really impressed us with the performance of their latest high-end platforms, and the soldering quality on their products is now good as well. This is a huge change for the company since they had mostly been a part of the mainstream categories thus far, but they now also seem intent on expanding into other categories.

On the solder side of the main PCB is a spot with three ICs. One of these is the supervisor IC, a SITI PS223 while the other two are the CM6901 LLC resonant controller we already mentioned and a Silicon Labs Si8230BD isolated driver.

The fan is of good quality since it is by Adda and uses double-ball bearings. Its model number is ADN512DB-A91 (135mm, 12V, 0.15A, 1500 RPM, 39.5 dB(A), 70,000-hour MTBF), and the same exact fan is used in the Andyson Platinum R 1200 W.
