PurePower 460W-NP (W0068, 460W)

It’s difficult to tell this power supply from the previous model visually as well as by the model name or even by the parameters. However, they are two different products. Particularly, the W0068 has an input voltage switch which means that it lacks active PFC (running a little ahead, I want to inform you that it lacks passive PFC, too). Another difference – you can see it when you turn the PSU on – is the blue highlighting of the fan.

The actual manufacturer of the PSU is again HEC/Compucase.

The internal design differs from the W0063 more. The different heatsinks should catch your eyes in the first place, but on closer inspection you can also find that this power supply is based on a different PCB (which is logical since the active PFC device was located on the main PCB in the W0063, while the W0068 lacks any power factor correction).

However, the W0068 employs in fact the same components and it shouldn’t matter much for the end-user how these components are placed on the PCB. The circuit design is unchanged, too. The PSU is assembled in an ordinary way with group voltage regulation.

What’s more important, the declared output parameters of the PSU are unchanged – it has exactly the same load capacity as the previous model. Of course, it now makes sense to write the output voltages with a slash since manual switching between them is required, but this is hardly of any interest for the user because the input voltage is usually selected once and for the entire lifetime of a power supply (and if it is set wrongly – the lifetime proves to be just too short :)).

The PSU offers the following cables and connectors:

• A mainboard power cable with a 20+4-pin ATX connector (60cm)
• A CPU power cable with a 4-pin ATX12V connector (62cm)
• A graphics card power cable with a 6-pin connector (61cm)
• One cable with 4 Molex connectors and one floppy mini-plug on each (61cm from the PSU case to the first connector and 15cm more to each next connector)
• One cable with 5 Molex connectors and one floppy mini-plug on each (61cm from the PSU case to the first connector and 15cm more to each next connector)
• One cable with 2 SATA power connectors (60cm+15cm)

So, the only difference from the W0063 is the configuration of the power connectors for hard and optical drives, but their total number is the same. Most users won’t even notice this because two or three such connectors are usually quite enough for a regular PC system.
