Conclusion: The ZM500-HP does exactly what it sets out to do, which is to power your PC without your ears knowing about it. The fairly low wattage won’t excite the gamer, but is more than sufficient for a media PC or a low/mid-end gaming machine.
Pros: Good rails, Silent, Blue LED???
Cons: No kettle lead, Underpowered, Little bit more expensive than other 500W PSU’s
