Ultra Products X3 ULT-HE1000X (1000W)

Having taken a look at models of a record-breaking wattage, I return now to a 1000W PSU again. This wattage has almost become ordinary already. So, it is a 1000W power supply from Ultra Products.

This PSU resembles the Floston ENFP-1050W I have discussed above, but it’s all right. Today, it is a common thing that identical products sell under different brands or different products sell under the same label. Judging by the UL certificate number, the PSU is manufactured by Andyson International, i.e. a third party for both Ultra and Floston. Let’s see if these two PSUs prove to be different in the tests.

The internal design confirms my supposition about the kinship between the PSUs: this one has two transformers, the same component layout, and same-shape heatsinks as the Floston unit.

That’s a dual-transformer PSU (as opposed to the PSUs from Thermaltake, the transformers are operating synchronously, governed by a common PWM controller) with active PFC and dedicated voltage regulation.

The single visible difference of the Floston unit is the selection of connectors: all of the Ultra PSU’s cables are detachable and there are six types of connectors for different cables. Here, I should express my comprehensions about the connectors again: the connectors for PATA drives (the top row) have open contacts, not separated from each other, and there will be a short circuit if any metallic thing is accidentally inserted into the connector.

The cables are flat and black, which looks very original. I described an Ultra ULT-XF500 power supply in an earlier review, which had similar cables, and complained that its cables were stiff and hard to lay out in the system case whereas the benefits of better ventilation were not so obvious. Fortunately, the cables of the ULT-HE1000X are softer, provoking no such problems. Still, I think that the material of the cables doesn’t have a big effect on the ventilation of the system case and it is an aesthetic rather than technical solution.

 

The total output power being 1000W, the PSU allows a load up to 70A (840W) on its +12V rail. The latter is not split into multiple output lines. To remind you, such splitting is implemented only to comply with the EN-60950 safety standard and has no effect on other technical properties of the PSU. Thus, the ULT-HE1000X is no worse in this respect than PSUs with four, five or six +12V lines. The non-split +12V power rail may even be viewed as an advantage as it gives the user full freedom in connecting the cables.

The PSU has the following connectors:

  • 24-pin connector for a mainboard power cable
  • 8- and 4-pin connectors for CPU power cables
  • Four 6-pin connectors for power cables of graphics cards
  • Six 4-pin connectors for power cables of PATA drives
  • Two 5-pin connectors for power cables of SATA drives

Included with the PSU are:

  • Mainboard cable with a 24-pin connector (47cm)
  • CPU cable with a 4-pin connector (47cm)
  • CPU cable with an 8-pin connector (48cm)
  • Two graphics card cables with 6-pin connectors (48cm)
  • Two graphics card cables with 6-pin connectors (56cm)
  • Graphics card cable with an 8-pin connector (49cm)
  • Graphics card cable with an 8-pin connector (59cm)
  • PATA-CDROM cable with one connector (18cm)
  • Two cables with three Molex and one floppy drive plug on each (43+12+12+12cm)
  • One cable with three Molex connectors (43+12+12cm)
  • One cable with three Molex connectors (28+12+12cm)
  • One cable with two SATA power connectors (48+12cm)
  • One cable with three SATA power connectors (49+12cm)
  • One cable with two SATA power connectors which is plugged into the PSU’s PATA connector (48+12cm)
  • One cable with three SATA power connectors which is plugged into the PSU’s PATA connector (48+12+12cm)
  • One cable with three fan connectors which is plugged into the PSU’s PATA connector (28+13+13cm)

On one hand, this list is very long indeed. The manufacturer put a lot of cables of different lengths into the box so that you could pick up exactly what your system needs. There is even a short 18cm cable for an optical drive that usually resides opposite the PSU.

But on the other hand, there are only two connectors for SATA power cables and two types of such cables those that plug into the PSU’s SATA connectors and those that plug into the PSU’s PATA connectors. I think a 1000W power supply should be oriented at modern systems in which there are almost no devices with PATA power supply.

Comparing this PSU to the Floston ENFP-1050W again, the latter has universal connectors for power cables of peripheral devices, and the manufacturer can include as many cables of each type as deems proper at the given moment.
