As you can see the unit works only with 220-240VAC power input, since it is intended only for the EU market. Also Antec promises up to 82% efficiency and has equipped it with a good set of protections. The fan uses sleeve bearing in order to lower overall cost and the weight of the unit is small, since the 350W capacity do not demand for large heatsinks/main transformer. Finally the warranty is a little short at two years, the minimum for all products sold in the EU, but with such a low price it's really hard to ask for more.
|Antec VP350P Power Specs|
|Total Max. Power||350W|
Only 350W total capacity, but this doesn't prevent VP350P from having two +12V rails which alone can deliver almost the full power of the unit. The minor rails are pretty strong too, for such a small PSU. Finally 5VSB can deliver up to 2A; we would like to see at least 2.5Α output here.
Cables & Connectors, Power Distribution
|ATX connector (390 mm)||20+4 pin|
|4+4 pin EPS12V (415 mm)||1|
|6 pin PCIe (410 mm)||1|
|4 pin Molex (355 mm) / SATA (+145 mm+145 mm)||1 / 2|
SATA (355 mm) / 4 pin Molex (+150 mm+150 mm) / FDD (+150 mm)
|1 / 2 / 1|
The available connectors are sufficient for the capacity of the PSU but the cables that hold them are too short. With 390mm length, the 24pin ATX cable will be compatible only with relatively small cases and the same applies to the EPS, PCIe cables too. On the contrary the distance among the SATA and peripheral connectors is adequate. Finally all connectors use 18AWG wires, which is the recommended wire gauge according to ATX spec.
|12V1||ATX, PCIe, SATA, Peripheral|
Power distribution is optimal since the EPS connector is powered from a dedicated rail while the first rail is not overloaded, since the PCIe connector is a 6pin one (however 6pin PCIe connectors can easily give more than 75W, which is their supposed limit, and reach even 150W) and the peripheral/SATA connectors are few.
