Neo HE combines the most desired features in PC power supplies with unprecedented efficiency in design. The Antec NeoHE 500 power supply's energy-efficient operation reduces power consumption by up to 20% compared with traditional power supplies, saving you money. It also generates less heat, and enables cooling with a smaller, slower, quieter fan. Active PFC circuitry further reduces impact on the power infrastructure. The result is cooler, quieter, and more environmentally friendly power.

Dedicated Power Circuitry, industrial grade protection circuitry, and Active PFC deliver safe, reliable output. Your new power supply is meant to be long-lasting, with an MTBF of 80,000+ hours.

The presence of one Main connector (20 + 4 pin), one 12V (P4), six peripherals, four SATA, one Floppy, and two PCI-E connectors are more than enough for all your components. Three +12V output circuits provide maximum stable power for the CPU independently of the other peripherals. This PSU is also ready to run SLI-enabled systems with no diminution in quality or reliability. Bring new power to your system with this remarkable supply!

4 out of 5 eggsSeems to work!

Pros: Works! Powered my old dinosaur right up. Best thing you can ask for in a new piece of equipment is that it does what it's supposed to, right?

Cons: Loud? Much louder than my old PSU anyway. There's several words in the product description about this being a quiet unit but... The variable speed they mention seems to be either low, which is indeed very quiet but it didn't spend much time there, or max, which is like a tornado on my desk. They tout the small fan, but honestly, all my experience with fans tells me smaller is louder per air pushed?

5 out of 5 eggsSolid PSU

Pros: This is a solid PSU. It actually is capable of pushing out more power than it is rated for.

Cons: None so far.

Other Thoughts: This PSU actually has 4-pin(P4) AND 8-pin(EPS) 12V connectors. It's not listed in the specs, and led to some confusion after my order had been placed. So rest assured, this has all the connectors you will need.

5 out of 5 eggsGreat PSU

Pros: Stable 12v Rails, very quiet. Modular is great for wiring.

Cons: A little pricey for a 500w at normal price, got this in a case combo with an antec 300, for nearly half price.

Other Thoughts: Great power supply, it powers up a big quad core office computer and several drives. No problems so far.

1 out of 5 eggs

Pros: Modular design

Cons: Price, quality, Warranty department is a nightmare.
It worked for 3 solid months then suddenly started restarting my computer in games.
A replacement power supply from a different company works like a charm how ever.
Because of this my previous review of 5 eggs is replaced with this review of 1 egg

Other Thoughts: I wrote a previous review praising this unit. After not having 3 of my 4 calls placed to Antec's warranty department not being returned even after leaving detailed messages I have lost my patience. I have yet to be issued a ticket id or a rma# from Antec. I will not reccommend any of their products to anyone nor will I ever buy one of their low quality products again.
