OCZ resurrects original Silencer PSU design

PC Power & Cooling’s Silencer 750W is one of our favorite PSUs. An Editor’s Choice award winner from several years back, the Silencer appeared in numerous system guides until it was eventually phased out. OCZ bought PC Power & Cooling and replaced the Silencer with a Mk II model that swapped the PSU’s trademark rear-mounted fan for a larger unit mounted on the bottom. That move apparently didn’t sit well with fans of the original, so the old Silencer is making a return.

At CES, OCZ showed a new lineup of Silencer PSUs with the old rear-mounted 80-mm fan configuration. Two units were on display: one rated for 760W and another pegged at 910W. Both carry 80 Plus Silver certification and 7-year warranties. They also have dual 6-pin auxiliary power connectors along with a pair of 6/8-pin plugs.

If you’re in the market for something a little fancier, OCZ showed its premium ZX series. This line puts a 140-mm on the bottom of the PSU and features units rated at up to 1200W. Despite higher wattage ratings, the ZX units are more efficient than the new Silencers and are 80 Plus Gold certified. They also feature modular cables and up to six 6/8-pin PCIe power connectors for multi-GPU excess. The warranty coverage tops out at five years, though.

Although not on display at the show, OCZ revealed that it’s working on a new high-efficiency PSU that will have 80 Plus Platinum certification. The platinum spec calls for efficiencies of 89-92% for loads between 20% and full capacity.

A platinum-rated PSU isn’t going to be cheap. But OCZ did have some less expensive units from the ZS series on display. This line spans 500-700W and offers 80 Plus Bronze certification. The ZS family lacks modular cables and only has three years of warranty coverage, though. The bottom-mounted fan is also slightly smaller at 120 mm.

    I want my next PSU to be modular, 80 Plus Gold, and capable of running a power-sucking GPU even if such a beast never gets plugged in, so probably 600 or 650 watts. I don’t care where the fan is or what size the fan is as long as it is quiet.

      ^ Seasonic X-Series 650

      Great supply, very affordable and ironically a replacement for an original Silencer 610 (I needed an 8-pin PCI-E for a 6970 GPU).

        Cool. Not all of us want a noisy power supply that is powerful enough to handle six-core Intel Core i7s and Geforce GTX 500 series video cards in three-way SLI.

          I’ve just put together my spanky new 2600K (which, for whatever reason, cost less than the 2600 – early pricing slip-up I reckon) and I’m quite happily running it off my trusty 380W seasonic. The whole deal (CPU, radeon 5770, two SSD, two hard drives, two optical drives) pulls about 180-200W from the wall if I’m playing a game whilst doing a video encode across all four cores.

          Anyone using integrated graphics can get away with a 150-200W PSU if they can find one that small, and most people with graphics cards will never need anything more than 400W. As to why >700W PSU’s have apparently become the new standard I have no answer other than “the stupidity of being impressed by big numbers”. I’m sure the germans have a word for that.

        I only started using seasonic after years of using pc power and cooling and corsair. Seasonic builds very high quality psu’s that are dead quiet and dead on as far as voltages are concerned.

          Seasonic are definetly one of the top PSU brands, and one of the few who manufacture their own PSU’s. Corsair and PCPC (like most PSU brands) outsource their PSU manufacturing, and alot or Corsair and PCPC units have been manufactured by Seasonic.

    In other news OCZ is getting out of DRAM

      Smart move. Margins and profits far too unpredictable.

        Unpredictable? Intel would agree with that. That is why they ditched DRAM 25 years ago with IBM’s help.
