Ultra has really expanded their power supply library. Today we look at one of their newest offerings in the form of a 600W, active PFC unit with a large 135mm fan and quiet good looks. It brings a single rail to the table but does it perform? Read on to find out.

The Ultra X-Pro 600W is the focus of my inquiry today. Not much is known about this particular unit because, as of today, it’s not a released product. As such there’s still a bit unknown about it. In fact, back in November when we first started pursuing this review, an engineering sample (ES) of the X-Pro 600W was all that was available. As such, it is with the ES that this review starts…

The label above tells us that this PSU has a single, 36A +12V rail. This is further confused by the fact that the wiring is color-coded for dual rails. Yellow wires to the PCI-e and everything aside from the 4+4 connector for the CPU(s). The CPU connector has yellow w/ black stripe as if it was on a +12V2. To figure out if this ES was indeed a single 36A rail I did a bit more investigating but I’ll cover that later.
I hope this label isn’t a sign that things are getting slim at Ultra 😉 The eagle eyed among you will notice that the rear of the PSU doesn’t have a 110/220 (or 115/230 as they’re typically labeled) switch for adjusting input voltage. That’s because the X-Pro 600W features full range active PFC. To those of us in the states it doesn’t mean much aside from a few benefits such as the input in wattage is closer to the input in VA. That and square wave UPS’ (which is nearly every consumer version out there) tend to deal with active PFC better than non-PFC or passive PFC. To Ultra it means that there’s no need to sell 2 PSU’s for the US and Europe. Now it’s just a matter of changing the connectors. For the uninitiated, Europe and the UK require active PFC for electronic devices to ensure that the grid sees them as a simple resistive load rather than a dynamic/reactive load.
Here’s a look at the wiring of the X-Pro. The wiring is shorter than the be quiet! 600W I looked at but not short enough to be an issue in all but the tallest of cases. It could perhaps be problematic for large cases with a bottom mounted PSU such as the TJ07. For a traditional case this PSU will be fine though. The cables are a trade off for a non-modular PSU, as that anything that’s unused will have to be bundled away. And the longer the cables the harder it becomes to hide the unused cables away.
The front of the PSU has slots allowing the heat from the PSU to flow back into the case. Happily, during testing I felt very little air coming from these front slots. On a 120mm and up cooled PSU you either have very little air flow at the front of the PSU (in a PSU case with no vents in the front) or you let heat escape it into the case. I’ll discuss why there’s very little air coming out from that vent when I rip ‘er open after the tests.

|Type of connector:|
|ATX connector||24 pin|
|2 x 2 12V connectors||1|
|2 x 3 PCI-e||2|
|8-pin Xeon/EPS connector||1(4+4)|
|6-pin Xeon/AUX connector||0|
|5.25″ Drive connectors||6|
|3.5″ Drive connectors||2|
|SATA Drive power connectors||4|
|Fan only connectors (thermostatically controlled 12V only)||0|
There are plenty of connectors without being overwhelming. I’d like to see 6 or more SATA connectors as it’ll easily fill up with drives once the SATA spec moves to ODD’s in a big way. Right now the Molex is king but it’s steadily losing ground.
