Tagan 2-Force II TG700-U33 700w PSU
Internals & Cables
In the past, many people have judged the quality of a PSU on it's weight and quantity of internal components. However, with many manufacturers moving on to newer and more efficient ways of designing their PSU's, it has become increasingly obvious that this is no longer a reliable method for gauging a power supply's quality. However, in the interest of having something fun to do, we'll be opening up the TG700-U33 and having a poke around.
For a PSU rated at 700w, I was surprised by the clean and uncluttered arangement of components inside the unit. From the images above we can see two fairly small yellow transformers manufactured by Viking. The smallest of the two transformers is most likely responsible for stepping down the power to the +3.3v and +5.0v rails with the larger being responsible for all four of the +12v rails.
Two large black aluminium heatsinks have been used to cool the mosfets beneath, with an arrangement of fins that compliments the direction of airflow through the unit.
As previously mentioned, both fans used inside the TG700-U33 are 80mm in size. However, after removing them from the casing, it's clear to see that Tagan have chosen two different fans, with the fan on the left being 25mm depth and the fan on the right being a much skinnier 15mm depth. Full details on both fans can be found below:
Model: S0801512HCables & Connectors
Size (mm): 80x80x15
Airflow (CFM): 27.2
Speed (RPM): 3000
Noise (dBA): 33.2
Size (mm): 80x80x25
Speed (RPM): 3000
Noise (dBA): 32.6
One of the things Tagan are well known for is their attention to detail when it comes to keeping cables tidy. Previous Tagan units have always featured their trademark shielded PCI-E connectors along with platted SATA and Molex cables. Let's see if Tagan has continued this trend with the U33..
As we can see from above, Tagan have decided to sleeve all cables right to the very last connector. Many manufacturers only sleeve some of the cables, or sleeve up to the first connector on every cable which can leave the PSU looking incomplete.
The sleeving job is of high quality, with fabric tape holding the sleeving in place and black heatshrink extending right up to the SATA and Molex plugs.
The ATX connector on the TG700-U33 is native 24-pin. However, as you can see above, a small block of 4 connectors can be broken off to switch the connector to 20-pin. As many motherboards still make use of the P4-12v 4-Pin connector, Tagan have chosen to include two separate cables for P4-12v (4-pin) and EPS12v (8-pin) standards.
With new graphics cards hitting the market that make use of the 8-Pin PCI-E connector it's good to see that Tagan have provided a connector that can be used in this format. For those of us who require 2x 6-Pin PCI-E connectors for configurations such a dual 8800GTS grapics cards, the 8-Pin connector can be reduced to 6-Pin by simply snapping away the extra two blocks at the end of the connector.
