Tagan 2 Force II 900W Cross Fire certified Power Supply Unit
Okay lets go through some of the details listed in the specs. Keeping up with current standards a 24pin motherboard connector is provided to support the extra power requirements by PCI Express cards. However if your mainboard only supports a 20pin connector, the 4 extra pins can be taken off.
To reduce the static electricity generated by the PSU this unit comes with the gold pin earth or ground wire just like in a conventional home 3 pin power socket.
One 4+4 pin CPU power connector is provided to power a Dual socket CPU setup or a quad core single socket setup. So which ever setup you got, the TAGAN TG900-U33 is able to handle it.
A single 4pin CPU power connector is provided as well in addition to the above.
4 x PCI-E power cables are provided of which two of them are the 6PIN PCI-E standard and two of the 8pin standard, so you’re covered for the latest and greatest of video cards. This is very impressive as not many manufactures really think about this amount of flexibility and add-ons in one single solution. ATI recommends the 8pin connectors if you’re planning on overclocking your system. These provide around 75-100W each so quite adequate for today’s needs.
Furthermore the PCI-E cables are Copper shielded to reduce ripple and noise. Ripple is the AC component superimposed over DC voltage, i.e. it’s the AC component that arises from a DC power supply from sources within the PSU. With the Copper shielding and patented REMI technology this PSU has reduced ripple and noise generated thus enhancing performance on graphic cards.
The TAGAN 2-Force II also comes with Internal OVP (Over Voltage Protection) and OCP (Over Current Protection) functions. These are features you wouldn’t see on normal PSU’s but are standard features on industrial grade PSU’s such as this one. OCP kicks in when the current in amps is greater than the rated current of the equipment it passes through, which can result in an overload or short circuit. With OCP if a situation as above occurs it’ll automatically cutoff the current protecting the components within.
In addition to this the TAGAN 900-U33 comes with APFC (Active Power Factor Correction) a feature you’d expect to see in higher grade PSUs. APFC automatically corrects for AC input voltage, is capable of a full range of input voltage, and diminishes total harmonics making the power supply more efficient under normal load. The TAGAN 900-U33 900W also boasts an efficiency rating of 80% which is good. On any PSU efficiency goes down with heat buildup, however an 80% efficiency rating is currently the most you can expect from high end units.
APFC is a complex power factor correction method so ultimately it’s more expensive to produce resulting in a more expensive PSU. However if you’re an enthusiast we do recommend going for a PSU with this feature.
