I've never heard of Xion or Axpertec but the Lan Party Edition 700W performed beyond my expectations. The DC load voltage regulation, DC quality and efficiency of the Xion Lan Party Edition 700W power supply is certainly approaching the levels expected of higher end power supplies but I have one or two reservations regarding the modular cable arrangement and performance of the thermally controlled cooling fan.

I don't like the use of universal modular cable connectors or daisy chained 6-pin and 6+2-pin PCI-E connectors on the same cable because they can and will lead to problems. It's not something normally seen on high end power supplies. The use of a universal 8-pin modular cable connector means the 3V3 and 5V0 rails have to be available to cater for the peripheral and SATA modular cables leaving only six ways available for PCI-E use. The first problem here is that the 6+2-pin PCI-E connector requires three ways for the 12V rail and five ways for the ground (0V) rail so something is going to have to double up with only six ways available at the modular cable connector for eight wires at the PCI-E plug. I'm of the opinion that it's cutting corners to keep costs down and I would much rather pay a few extra dollars for dedicated cable and connectors for PCI-E and peripherals usage. Most, if not all of the high end power supply manufacturers would never daisy chain a 6-pin and 8-pin PCI-E connector on the same cable. They come individually connected to their own dedicated cable. The GTX 480 graphics card for example, requires one 6-pin PCI-E and one 8-pin PCI-E connector, so how do you supply the auxiliary power to this card? The Xion Lan Party Edition 700W power supply has one captive cable with a 6-pin PCI-E and then a daisy chained 6+2-pin PCI-E connector available and it will be used by some builders to power the GTX 480 - not ideal!

The thermally controlled cooling fan threw me a little because I've never seen behaviour like it on other power supplies and full DC load has always resulted in the fan speed ramping up to full or near full speed, but not this time. I contacted Aspertec and they informed me that because I was testing out of case with an ambient temperature of approximately 21°C the internal temperature of the power supply was not reaching a high enough level to trigger the thermal fan control. I haven't got a hot case (something to think about) or a suitable PC that can put a 700W load on the power supply so testing the operation of the cooling fan thermal control proved difficult. I did however, manage to locate the temperature sensor on the secondary heat sink and raise its temperature a little whilst under full load on the bench. It took only a few degrees rise in temperature to cause the fan speed to increase so following the OCC testing methodology, I have to presume the thermal fan control is working as the manufacturer intended although I do have some minor reservations about its sensitivity.

So what can be said about the Xion Lan Party Edition 700W power supply? Great electrical performance, minor problems, in my opinion, with the modular cable configuration and a thermally controlled fan that would appear to function with changes in temperature but not quite as I would have expected. Changes to the modular cable configuration and thermal fan sensitivity would turn what is already a good power supply into a great one and I have no hesitation in awarding the Xion Lan Party Edition 700W power supply a OCC Bronze award.
