HEC Ace 580UB 580 Watt Power Supply Review
HEC Ace 580UB 580 Watt Power Supply Review - PCSTATS
Abstract: This all-black dual-fan PSU pumps out a maximum output (peak) of 580Watts, which should be quite sufficient for SLI and just about anything else you can throw at it.

Performance Tests

Power Jitter Observations

Voltage jitter is read by accessing the power options displayed in the motherboard BIOS, with the system obviously in an unloaded state. *All voltages were read from the Motherboard BIOS of a ChainTech Zenith VNF4 Ultra motherboard.

Listed Voltages Lower Voltage Upper Voltage Jitter
+3.3V 3.26V 3.28v 0.02v
+5.0V 4.99v 5.02v 0.03v
+12V 11.84V 11.90V 0.06v
-12V -11.78V -11.78V 0.00v
-5.0V -5.01v -5.01v 0.00v
+5.0Vsb 5.00v 5.00v 0.00v

Good solid performance from the AcePower 580UB here. The +12V line might be a tad low, but it's generally solid and the +5V line numbers are excellent. Looks like you can rely on this HEC power supply to deliver stable and accurate power levels.

Seasonic Load Tests Source: Seasonic

When looking at the Seasonic Power Supply test results we see two values, wattage and volt-amps. Since it might not be clear what they measure, here's a brief overview.

The volt-amp (VA) value is how much real power is being consumed by the power supply being tested to provide the wattage (W) value. The higher the VA value is, the more electricity is being used by the power supply. Because no electrical device is 100% efficient, there will always be some loss when converting AC to DC. The closer the volt-amps and wattage figures are to each other, the more efficient a power supply is. This is called the Power Factor: wattage / volt-amps = PF.

Since we're testing with a 120W dummy load, the load on the power supply (wattage) should be as close to this figure as possible. Anything above this load in apparent power describes the overhead and wasted energy (given off as heat) for the particular power supply being tested.

For the unloaded tests, the wattage and volt-amp figures should be as close as possible to one another. The lower the figures are, the less power is being used.

The HEC Ace Power 580UB proved to be about average in terms of efficiency when compared to the rest of the non-active PFC test group. Next to an Active PFC supply there is no comparison at all in terms of power efficiency, which is expected. When unloaded, the 580UB showed average efficiency also.

The HEC Ace Power 580UB did well in terms of power consumption. It's loaded consumption was the lowest of our non active-PFC group, but its unloaded consumption was a little higher than some of the competition.

Powerful, fairly efficient and fairly attractive

HEC has built a lot of nice features into the Ace Power 580UB PC, starting with its ample wattage and current abilities and the dual video card connectors it offers for SLI systems. We were also impressed with the copious connection abilities that this PSU boasts as well as its efficient (for a non-active PFC power supply) and stable performance.

If you are looking for a beast of a power supply to run your cutting-edge desktop system, the HEC Ace Power 580UB is a good choice, and as a bonus, it will add to the look of any modded case.

HEC offers a three year warranty on the Ace Power 580UB, which should give you some peace of mind. We couldn't find a retail price for the PSU, but I'd estimate it at around $85USD, and at that price it is worthwhile to consider.
