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. The SLI sticker on the box seems misleading, but the 600w version will do the trick for multi-GPU owners.
Pros: Good rails, Silent, Blue LED???
Cons: No kettle lead, Underpowered, Little bit more expensive than other 500W PSU’s
