Antec has been offering power supplies for quite a long time now. Their power supplies are synonymous with value and performance, with their Basiq, NeoPower, TruePower Trio and Quattro series. The Signature series breaks away from this and offers up a power supply like no other. Antec's Signature series of power supplies are of the highest quality, featuring true wattage ratings along with top of the line components, such as Japanese branded capacitors and cooling fan. These power supplies also offer modular power cables, SLi Certification, 80Plus Bronze certification and a test report, certified with a signature. Truly unique. Previously, we have reviewed the SG850, the 850 Watt model from the Signature Series. Now, we are going to take a look at its younger sibling, the SG650, a 650 Watt model.

Despite its silent performance though, we're still far from convinced by the Fenris Wolf, with the easily dented and deformed panelling our primary concern. Scythe seems to have totally omitted reinforcing any of the case's panelling with the usual methods and it's clear that this isn't a case that's going to stand up to much wear and tear or even multiple fittings without showing some very obvious signs of degradation. It's a shame really as the black anodised aluminium Scythe has used feels and looks great -- it's just not strong enough without being reinforced in some way.

The Fenris Wolf isn't the easiest case to put together either, with the rubber grommet mounted hard drive rack particularly frustrating to build and the mount into the chassis. On more than one failed attempt at mounting the test system hard drive came close to being hurled across the room in frustration -- it's just a million miles away from the easy drive mounting trays used in Cooler Master or Antec chassis and while we appreciate the excellent vibration reduction it can offer, we're not sure it's worth the bother. Again, it's a shame as Scythe has gotten the basics right with the roomy interior and easy PSU mounting, it's just spoiled by the irritating hard drive mounting.

The final nail in the coffin here though is the price. Launching next month at almost £135 we feel the Fenris Wolf is, simply put, comically expensive. The Hiper Osiris, a case that's based on the exact same core chassis and which possesses far superior aluminium alloy build quality is available for just over £80 -- that's a whopping saving of almost £55, more than enough to replace the Osiris' three (admittedly noisy) 120mm fans with ultra low noise models and have enough left over to buy a new game or two.

There's also the option of the Akasa Omega for £120, a case that's comparable to the Fenris Wolf on thermal performance and excellent noise levels, but that's both fantastically easy to work with and very solid indeed, with superb build quality.

While the Scythe Fenris Wolf is launched as a silent case to the Osiris' high performance, there's just no way that two ultra low noise fans, a vibration dampening hard drive mount and some foam strips stuck on the side panels are worth the sort of price premium Scythe is demanding here, especially with the notable build quality and hard drive mounting problems we've encountered.

It's a real surprise to be honest, especially as the core chassis upon which the Fenris Wolf has been built has been at the heart of two high quality cases. Sadly though, that's not the case this time out and the Fenris Wolf, while at first seeming to have a lot of potential, just carries too many flaws to be really worthy of your consideration.
