Silverstone's Zeus performs like a PSU named after a God. Completely solid rails at 650W of output power, masses of capacity on +12V with high efficiency and a focused 80mm fan that gets rid of all the heat. A pair of PEG connectors for SLI or Crossfire are paired with EPS and SSI making the ST65ZF. If you've got a big bad server to run, or the highest of high end desktops, the Silverstone makes a great case for itself.
Recommended system: Mid-range to high-end desktop systems based around P4 (including high-speed Prescott), AMD Athlon Socket A and AMD Athlon 64 and Sempron on Socket 754 and Socket 939. High-end server systems.
HEXUS.note
Silverstone recently contacted us to let us know the ST65ZF does indeed have two PEG connectors (something we ommitted) and was actually one of the first SLI certified power supplies. In light of that and double checking that's the case, the ST65ZF's Recommended System rating has been changed from "High-end server systems" to what you see now. The PSU spec has been updated to say 2 x PEG as well as EPS and SSI.AOpen AO700-12ALN

The AOpen AO700-12ALN is an engineering sample of a design they've created whose connector bundle isn't final. AOpen plan to use the internals in an enthusiast-class PSU and wanted to know what I thought. The full 700W of output power being made at 82.82% efficiency without any huge heat issues left me gobsmacked. +12V was a little on the high side under heavy load, but a whopping 60A of current capacity from four separate +12V rails more than makes up for it.
They hinted that the design was capable of a frankly rediculous 900W or so of true output power at 75% efficiency, should they wish to set it up that way.
They've been experimenting in the labs to come up with a design for the enthusiast and while it won't be cheap, it should perform like a champ given the showing of the engineering sample.
Recommended system: Unavailable, but should be in the future.
FSP Group Epsilon FSP700-80GL
FSP contacted us recently (3rd week of August) to let us know that a similar configuration will be sold by them at retail under the Epsilon brand. Their FSP Group Epsilon FSP700-80GL is a 700W supply with similar characteristic. Connector configuration is still to be decided and we'll let you know what it is as soon as they've finalised it, but expect dual PCI Express graphics power, plenty of SATA and a modular ATX cable. Hopefully presentation will be spot on, too.The certification for the Epsilon FSP700-80GL is complete, the unit passing CE and complying with the European Low Voltage Directive and FSP have used an external testing house for the certification. Look out for a full review of the unit as soon as we can get our hands on one.
