Be Quiet SFX Power 2 400W Power Supply (PSU) Price Compare & Review


Be Quiet SFX Power 2 Review

The SFX power supply form factor is fast becoming the most common power supply type for HTPC media centres. SFX power supplies are designed to be super small, energy efficient and deliver the power needed for the latest home computing components. An SFX power supply is less than half the size of the standard ATX power supply and as a result pumps out a lot less noise. Your power supply choice is of course dependant on the case you are using but if it will take an SFX power supply then there are many benefits in doing so.  SFX PSUs are generally more expensive than the ATX form factor but worth the addition expense.

HMP Verdict

If you have not seen one before you will be surprised how small these power supply units are compared to the standard ATX form factor range. The Be Quiet SFX Power 2 400W PSU fits easily into some of the lower profile HTPC cases and comes with all of the connections, cables and fittings you get with ATX. The available 400W of power was more than enough to power a mini-ITX motherboard, Intel I7 CPU, 4TB HDD and gaming graphics cards with enough power left for some extras (we added a slot loading Blu-ray reader and a number of USB devices). When they say the Be Quiet SFX Power 2 400W power supply is quiet they mean it! On our test HTPC media centre you literally could not hear the PSU. The CPU cooler and SATA hard disk were far louder and you would not know that the power supply had a fan in it. This is perfect for a media PC designed for watching movies and video content. If you want a HTPC media centre that has low running costs then the efficiency of this PSU will give you that. This low running temperatures of the Be Quiet SFX Power 2 400W PSU may mean less case coolers are required for your design. The cost of the Be Quiet SFX Power 2 400W PSU is slightly higher than an ATX equivalent but is well worth the additional expense.
