XPG Fusion 1600W Titanium Power Supply Review

A Closer Look – Interior

The fan is a HA13525H12SB-Z, one of the most common fans on many high-end PSUs on the market today, I see it in most of my PSU reviews. There’s a large shield on here to prevent debris from getting into some of the higher voltage components, not uncommon on PSUs, but they’re usually transparent not black.

With the case opened up, it does look like there are two power supplies smashed into one here, and that actually isn’t far from the truth, as I can see two main bulk capacitors, two transformers, two 5v and 3.3v converters, and well, to get to 1600-2000W, it does take a lot of hardware.

There are a lot of additional boards in here, such as this active APFC modular which has a finned heatsink that’s pressed up against the side of the PSU housing. That would restrict airflow and be of concern, but it’s such an efficient PFC unit that cooling just isn’t an issue.

There are two transformers, again with another control board between them. Where possible the PSU appears to use solid-state connections or fixed control boards direct to the main PCB rather than use wires. Everything is far more shielded than usual too, with protective film between most components, albeit that’s hard to see in some of these pictures.

Where big voltages are concerned, pretty much everything appears to be doubled up on, from capacitors to converters.

The AC Line-In uses thick wired, two shielding blocks, and again, it’s just very robust looking.

What’s missing are big heatsinks, you usually see large fins on the bridge rectifiers, but these Infineon IPDQ60R010S7 units are so efficient, that they don’t need cooling! There’s a lot of that marshmallow-looking material too, it’s some kind of thermal compound, but it’s hard to the touch, acting like a bonding agent too.

At the heart of the power supply are these two enormous bulk capacitors, each rated for 450V and 820 uF, making 900V and 1640 uF in total, with additional capacitors littered around the housing that are frankly too numerous to count without a full disassembly of the unit.

There’s a wall of PCBs stacked in rows, with banks of capacitors and chokes, ensuring the PSU can deliver both high power and low ripple on all the rails. There are hard metal interconnections rather than cables, and there are numerous black cables for voltage monitors and temperature sensors too, there’s just so much going on here!
