Xilence Performance X Series 850W Power Supply Review

October 11th, 2017 Raffaele Leave a comment Go to comments

Overview

 

Today, we have a Power Supply from German-based manufacturer Xilence. If that isn’t a name you have heard of, then you are not alone, as this review is my first encounter with the company as well. Not only that, but this is the first review that pcGameware has ever conducted on a product of theirs.

This particular unit comes from a brand new range (X Series) from Xilence. All are 80+ Gold rated, therefore promising up to 92% efficiency at peak. They range from 550 to 850 watts in total delivery, with – in the case of this unit – 849.6W of that figure being available on the single 12V rail. These are, naturally, figures we are both keen to see and try out!

Each Power Supply in the range is semi-modular, meaning that the main 24-pin Motherboard power cable and the 4+4-pin CPU/EPS cable is attached permanently to the unit. The PSU is cooled by a single 120mm fan, and measures in at 160mm (L) x 150mm (W) x 87mm (H). As such, it should have little difficulty fitting into even ATX PSU compatible ITX towers and small form factor cases.

 

‘Launching the Performance X model line, Xilence is extending the already favorable portfolio of power supply units. Following the ErP2014 conform entry-level models and the successful Performance A+ Series, the next step is made into the 80+ GOLD class. The PSUs score not only with the up-to-date DC/DC technology which guaratees an all-time stable output voltage.’

 

 

The unit comes to pcG in a fairly smart (if plain looking) box, with a fairly attractive watercolour/vector style rendering of the unit displayed prominently on the front. It’s a small touch, but I like this a great deal, I must admit. Call me a sap for aesthetics!

The top right of the box shows what is Xilence’s chosen slogan, “The Passion of Power.” Again, it’s understated, and not your fairly typical approach taken with PC parts of being overtly brash/in your face. 😮

The bottom of the box (on the front face) proudly displays that 80+ Gold ATX rating, alongside several claims from Xilence. These are:

  • Less than 0.25W Standby Power.
  • Superior Airflow Design.
  • Ready for Graphic cards.
  • Comply with ErP 2014.
  • LLC+ DC to DC Design.
  •  

    Finally, there is some self-promotion on Xilence’s part, with links to their full website and Facebook pages.

    Flipping the box over, we continue to see a fairly minimalist approach to advertising! An image of the PSU is shown prominently on the right hand side. To the left, we see the list of cabling one can expect with this PSU.

    The main ATX cable is 600mm long, with the CPU cable also being the same length. Each of the peripheral connectors (namely the SATA chains, single molex chain & PCIe power cables) are 500mm in length.

     

     

    On opening the box, we see two leaflets. One is a warranty extension card, the other is a very basic instruction manual. There are no visual instructions, but – then again – installing a PSU and using it doesn’t exactly require much skill and/or know-how.

    A single piece of foam protects one side of the PSU from knocks, but it is fairly safe to assume that the thick wrapping the unit initially shipped in would do a fine job of also preventing shock damage.

    A black flip-up cover protects the modular cables, which are simply wrapped together by a single long cable tie. The cables themselves are nicely braided, as well.

    What is genuinely appreciated here is the total absence of any of the dreaded ‘ketchup and mustard’ cabling that you may find on cheaper/lower end power supplies. They are all black, nicely braided, and overall feel good.

    What is, I will admit, slightly mystifying are the relatively high amount of molex connectors available on the modular cables. Whilst I appreciate that it is still a connector that ‘some’ cases use (e.g. for fan hub power), I really think – in 2017 – their use should be coming to an end. ED: AGREED!

    I would have also appreciated, perhaps, at least a black cloth/synthetic bag for the cables? It would not cost much, and it would certainly lend a more ‘premium’ air to the unboxing experience!

    In a small bag there are four silver screws, though any decent Case today comes with the ability to mount the PSU, either in a bracket or direct to the chassis using included screws, so you shouldn’t need to use/consider these. I should also note that this PSU was actually supplied with an EU power cable, and not a UK one!

    At the time of review the Xilence Performance X Series 850W Power Supply is not yet for sale here in the UK. The RRP is approximately €129.00, we will update the review with links once they are known.

      First Impressions

       

       

      My initial reactions at seeing the unit were good. The unit looks simple but seems sturdy, well put together, and looks the part. There is no effort wasted on flashy features that will simply go unnoticed. It is, for what it’s worth, also relatively heavy. The unit is a good 20mm shorter in length than the be quiet! Dark Power Pro 11 unit that I’m replacing it with. Whilst not to be taken as gospel, the unit is on the shorter side for an 850W unit, but is by no means diminutive or small.

       

       

      As said before, one side of the unit displays the same spec sheet as is printed on the box. The other side houses the Xilence logo, simply stamped into the black metal of the housing. If Xilence have been trying to go with a very minimalist/utilitarian aesthetic, it seems to be continuing here! That said, the unit is attractive for sure, but the presence of a striking red 120mm fan seems a departure from the previously established ‘minimal’ look/feel.

      The back of the unit, has – which is good to see – a fully open honeycomb design, allowing for maximum possible airflow provided by the 120mm fan.

      The front of the unit is, for an 850W unit (at least in my opinion) fairly sparsely populated. The PSU allows for two PCIe cables, two molex/berg chains, and two SATA power cable chains. Molex is an increasingly rare connector in 2017, and I honestly cannot think/recall of the last time I ever needed a berg/floppy power connector. That said, other manufacturers are still, for whatever reason, still including berg plugs in their units, so I guess it’s fair enough.

       

       

      Each SATA chain has three individual power plugs on it, allowing for a max of 6 connected drives. For most, this will be more than is really ever needed, especially given the advent of NVMe/SATA drives in the M.2 form factor.

      Each PCIe connector has 2x 6+2 connectors, therefore technically allowing 2 GPU’s with dual 8 pin connectors to be used. These are red ended, presumably to double ensure that a hapless builder does not attempt to jam them into the CPU socket? 😉

      Testing Methodology/Setup

       

      The hardware used (that matters for this review!) was as follows:

    • AMD Ryzen 1700X @ 3.8GHz, 1.35v VCore
    • Asus X370-F Strix motherboard
    • 16GB (2x 8GB) Crucial Ballistix Elite DDR4 3200MHz
    • 1x EVGA Nvidia GeForce GTX 1080 FTW2
    •  

      When it comes to reviewing PSUs, there isn’t much one can do beyond examine it under load, measure rail voltages, and take a look at claimed efficiency.

      For this test, we shall be putting the entire system under a combined load of both AIDA64’s inbuilt stress test (with CPU, FPU, cache, and memory stress all used), and the new Unigine Superposition benchmark, using the maximum allowed preset.

      The GPU, for this test, was run at the maximum stable overclock that I have been able to achieve with it. No additional voltage was used, but a core offset of +75MHz was added, as well as a +300MHz offset to the GDDR5X memory and the obligatory 120% power target.

       

      Hardware Performance

       

       

       

      Voltages at idle were within Intel specifications, at 12.164, 4.959, and 3.270 respectively.

      Using AIDA64’s logging feature, we were able to see the fluctuation that takes place when a unit is placed under a heavy load.

      From an idle voltage of 12.164, the highest fluctuation we saw (down to 12.099) was just 65Mv! This is well within the Intel specification for ATX PSU tolerances. The 5v rail saw just 27Mv of droop (down to 4.932v), and the 3.3v line saw – oddly – a slight spike up to 3.293v.

      All of these are, again, well within Intel’s ATX PSU voltage tolerances, and so the unit – here – gets an overwhelming pass. It would be interesting, however, to see how well the unit copes under a heavier load (e.g. an SLI setup).

       

      • x1 Nvidia GeForce GTX 1080

      During the test, the maximum recorded draw during the Superposition/AIDA64 test was 377.5W. To all those thinking ‘is a 550W PSU enough (for a single GPU and unlocked CPU) in 2017?’ There, for most of us, is the answer!

      If we round up that figure to assume the PSU is at approximately 50% load then a claimed 92% efficiency rating (at 50% load) means the PC was consuming approximately 347.7W under full load.

      Final Thoughts

       

      This is an excellent unit. Let me first just say that. I had high hopes when I felt the weight of it, and have absolutely no doubt that this PSU would hold up well to a beefier SLI/Crossfire setup.

      So… do I have any real gripes?

      Potentially, yes, but none of them are related to the performance. I would argue that, for €129.00 (approx £117.00), there is a distinct lack of documentation or any ‘luxuries’ at all. Now, I will make the point (again) that PSU’s aren’t exactly demanding of their user to install. With that, when paying this much for a power supply, perhaps some more notable documentation or ‘in box’ luxuries wouldn’t go amiss?

      I was, also, initially apprehensive at this unit’s price, in a world largely dominated by the likes of EVGA, Corsair, Seasonic etc, you get my point. For £117.00, I really thought this unit would have to truly excel to be worth considering. Especially considering that – right now – units like Corsair’s 850W RMx and Seasonic’s Focus Gold 850W are available for £111 to £116 respectively.

      Whilst a case could be made for this unit being somewhat too expensive to be attractive (in a world where the average PC builder will largely stick to what he/she knows, or is told about), it’s performance goes a long way in justifying its price against the more traditionally established competition. It never, not once, put a foot wrong. So, with that in mind, what do I like about the unit? Well, actually, many things…

      It is good looking, extremely solid and well built, comes with a good quantity of well-sleeved cables, and is – arguably – everything one could want out of a Power Supply. I think it should be cheaper, certainly, but in terms of pure performance, I have absolutely zero complaints.

      Yes, for sure, the voltage tolerances ‘could’ be better, but they are well within specification and ergo should not be something to worry yourself with. In fact, I would feel harsh taking a point off for this, given that there was such little fluctuation between idle and load scenarios. Also, let’s remember that said load scenario was, for the most part, a deliberate ‘torture’ test!

      It is attractively packaged, for sure. Whilst accompanying documentation may be very thin on the ground, my point about that being a relative non-issue I think is one I’ve made a few times already!

      All in all, I would have zero issues in recommending this unit to those looking for a well priced, well built, and capable Power Supply. The main issue is, naturally, going to be convincing those who have never heard of the name ‘Xilence,’ before, to buy one!
