Apevia Internal Power Supplies SFX-AP400W Editorial Review
The APEVIA SFX-AP400W Mini ITX Solution Micro ATX SFX 400W Power Supply is highly rated by customers who have bought it. It is a small form factor power supply that can be used with SFX, micro ATX and ATX units with an adapter. The lack of a light indicator does not make a difference in telling if it is working as the power supply fan can be seen turned on. Unfortunately, it is not powerful enough to power all graphics cards that connect through a PCI-e connector, but can be used to power any PC with the exception of powering a high-end graphics card. As this is an SFX power supply, it is not compatible with small form factor slim power supply units. The company also makes a 600W version that is slightly more expensive than the 400W model. **
