Andyson is a name that these days few PSU buyers are likely to recognize. The company has been around for almost two decades, but until very recently has struggled to make a name for itself, having been dogged by issues such as the poor reputation of Hiper's PSUs, which were based on Andyson platforms and were quite unreliable.

Looking to recover from these events, the company recently set about improving their quality and their reputation in the process, and as a result the company is making a strong comeback this year. They have released numerous new designs, most of which they are retailing under their own brand name. A few weeks ago, we had a look at their flagship, the Platinum R 1200W PSU, and our testing results were very promising.

However, as excellent as the Platinum R 1200W is, it is a product aimed at a very small and saturated market. Having a very good flagship PSU is good for every manufacturer because it serves as a symbol of the company's capabilities and competence, with a strong showing at the top often boosting sales across the board. On the other hand, it is the low and middle output units that actually generate the bulk of a company's revenue. Today we are having a look at such a unit, the N500 Titanium.

As its name suggests, the N500 Titanium is a very high performance 500W PSU capable of meeting 80Plus Titanium efficiency levels. Technically, only the 700W unit of the series has an official 80Plus Titanium certification so far. But with the 500W unit based on the same platform, we do not expect that it will have any trouble meeting the certification either. The MSRP of $110 is a little high for a 500W PSU but, depending on its performance, it could entice those that want a very efficient unit but do not need a high power output.

Packaging and Bundle

The N500 Titanium is supplied in a medium-sized cardboard box, covered by elegant artwork resembling brushed metal. Inside the box, the PSU is protected by a thin layer of polyethylene foam and a nylon bag. Given its relatively low weight, the packaging should be sufficient for shipping protection, although we would like to have seen better protection for such a premium product.

Alongside with the standard AC power cable, a manual and four black mounting screws, Andyson also provides four thumbscrews, several long and short cable ties, as well as three cable straps. It is a well thought and practical bundle.

The N500 Titanium is a semi-modular design and Andyson supplies the extra cables in a small nylon bag with a zipper. Peculiarly, the cables themselves are very basic, with color-coded wires wrapped in black sleeving.

    80+ Titanium requires 90% @ 10% load, 92% @ 20% load, 94% @ 50% load, 90% @ 100 load, on 115v.
    The only 80+ 85% requirements are 80+ Silver @ 20% load, and 80+ Bronze @ 50% load.

    This is hands down the most interesting PSU reviewed on AT ever and I could not disagree more about the assessment that his might not even pay off compared to the 80Plus Gold PSU (you're even suggesting going higher with the wattage which means even higher losses at usual power levels!). Here in Europe we typically pay 23+ cents per kWh and rule of a thumb is 1W 24/7 power draw will >2€ per year; if you have devices running permanently or huge efficiency gains you can easily save 10€ per year, in some cases even 25€ or more.

    I've done lots of tricky conversions and downsizings in order to keep energy use down as much as possible and this is a very simple and cheap solution compared to all others so this is an instabuy for me (if I can actually locate one).

    Keeping your computer at full load really is the only situation where going above gold will pay for itself; especially in places with cheaper power. The average price in the US is ~12c/kWh, or $1/watt year. At our prices platinum units generally took 4-6 years to break even on a 24/7 full load box; and never would if your computer spent most of its time at idle/standby/off. Hitting the titanium standard without bumping up the price a lot makes this one a much better deal at full load. If your box spends most of it's time at idle or off, the 2-4W average savings will push your baseline break even point out to between several years (24/7 idle, EU power prices) and never (off when not in use, US power prices).

    As Arbie's noted the amount of time you need to run the heater vs the air conditioner can tip the scales a decent amount either way, and that's very geographically dependent.

    I disagree about the load. There're actually several aspects to this: More efficient PSUs are only available at higher ratings however most of them are at the same time abysmal at low loads where low is also defined as a percentage of the maximum rating. Titanium raises the bar tremendously above Platinum because it adds the quite important 10% tier where most of the Platinum PSUs plain and simply suck.

    Essentially there're only three options for best efficiency:
    - Take the smallest possible PSU with a gold rating
    - Use a PicoPSU/MicroPSU with a crazily efficient power brick
    - Take this PSU (if it's not completely overkill for the system which it might very well be)

    I've optimized numerous systems in my home, not only because of the power bills but because I'm in generally interested in efficiency in the hope that we can actually preserve the planet long enough for my grandchildren to have a decent life. From that experience I can tell you that a carefully chosen PSU alone can make a huge difference; with careful tuning and by replacing the PSU my Sandy Bridge based virtualisation environment and home server (24/7 on) went down from an already decent 75W to a nice 35W; the 20W that came from the PSU alone save 40€/year.

    Just for kicks I tried powering my small gaming and HTPC with a 700W platinum PSU, in idle it used around 50W, in FurMark 200W, while my 300W bronze PSU only sips 25W in idle and 150W in Furmark. Now that system only runs sporadically but that's still a whopping difference.

    I know AC and heating can make a huge difference (I'm also operating servers professionally) but in my home (and for the specific topic we're discussing) it really does not matter; a properly built home has to stay reasonably cool even without AC, so I don't have one.

    I would certainly pay extra for a very-high efficiency PSU. All the arguments I've seen regarding the cost of electricity ignore two important factors. First, unless you need heating in your room, the power dissipation of your rig has to be paid for about THREE times. Once for its own electricity, then 2X that for your air-conditioner to remove that heat. Another factor is that you may have to overcool several other areas to keep your computer room livable. Then there's comfort - it's no fun having cold A/C blowing on you much more than necessary.

    Of course you have to consider the deltas, proportionate gains, and costs - but a high efficiency PSU can be a better choice than you might think at first.

    well the heating is not a problem in most of the developed world. It's better to invest in recladding of old buildings really.

    Also overcool several other areas? Don't you have thermostats in each room?
    In most of the world there isn't central air con outside of big buildings anyway so it doesn't matter.
  • SodaAnt - Thursday, October 8, 2015 - link

    Central air con is pretty common in the US. Main issue with it is that you have to cool the whole house even if its only one room that's hot, or if you're only staying in one room.
  • DanNeely - Thursday, October 8, 2015 - link

    Central/forced air heating/AC is common in the US. At least in older construction a single thermostat is common. However, in most cases you'll have some ability to adjust the per room airflow by varying how open the vents are. If you've got a small massively overcomputed mancave you might be able to swamp the adjustability limits; but they generally are good enough to keep temperatures constant in a normal sized house.

    An efficient PSU can also help ke

    Whoops. I meant to say:

    An efficient PSU can also help keep fan noise down and lifespan up. If lost productivity from fan whine/failure is large then a modest investment in an efficient PSU is a bargain.
