X-bit Labs assembled a number of PSUs to compare; the Hiper M600 650W, Scythe's Stronger 600W, Antec's Neo ECO 620C 620W, Enhance's EPS-1280GB4 800W and the Scythe Chouriki 2 850W.   Most of the models are modular and several have 80+ ratings but unfortunately none stood out as shining examples of a PSU in their particular wattage.  Still, it is nice to see a quick comparison of common PSUs found in prebuilt systems, such as the Antec Neo ECO which was pulled from an Antec Sonata IV.  Check it out here.

Thermaltake have updated their lineup of PSU testers with the Dr. Power II PSU Tester, giving digital readouts on the health of any PSU up to ATX v2.3.  With it you can measure your +12V, +5V, +3.3V, 5VSB and the -12V rails to within 1/10th of a volt.   Every connector is present for you to test barring the 4-pin floppy connector, which is so infrequently used that it is no great loss.  ProClockers have seen it in sale for $30 and highly recommend it to anyone who spends a fair amount of time testing and fixing PCs.

"I am sure many of you that frequent friends and family members PC station, the first thing you hear when the PC fails to boot is “I think the power supply is dead”. This may or may not be the case but in order to confirm this is to give the PSU a quick test to see if all the rails are working properly. Several companies have sent their version of this particular type of product to our lab. Today, we will be taking a look at the latest Dr Power II from Thermaltake. The Dr Power II has an over-sized display and able to measure idle rails voltage with pretty good accuracy."

Is it worth investing in an 80+ rated PSU to save yourself money?

Subject: Cases and Cooling | October 11, 2011 - 01:19 PM |
Tagged: PSU, 80 gold, 80+ silver, 80+ platinum, energy efficiency

For most there are two main reasons for paying the premium price to purchase an 80+ rated PSU; the eventual money savings from lowered power costs and to reduce your carbon footprint by using a more efficient PSU.  [H]ard|OCP put the first reason to the test, examining several cases of usage for PSUs of differing wattage and usage.  As well, they point out the issues with some ratings, as PSUs that are labeled as 80+ Platinum only deserve a Gold rating in most usage scenarios.  Their findings are based on theoretical usage patterns, it is hard to imaging a PSU operating at 50% load day after day, but this will give you an idea how many days or years it will take for you to start seeing a return on your investment.

"A HardOCP editorial about the 80 Plus program and how it is changing the computer power supplies you are buying. Is this good, bad, or ugly, and should you care? Did you know that you paid for that 80Plus rating on your shiny new PSU? Certainly PSU efficiency is a great thing, but what about the rating system?"

Kingwin aims to deliver silent power with their new 500W Stryker

Tagged: PSU, Kingwin, Kingwin Stryker 500W, silent, fanless

Not too long ago Lee gave the PC Perspective Gold Seal to the Kingwin Stryker 500W Fanless PSU thanks to the superior power quality and five year warranty.  Just in case you weren't swayed by his testing, you can double check the results over at Think Computers.   They tried the same PSU with a different test machine set up and came up with the same results, a 80PLUS Platinum rated silent PSU that delivers everything you would expect.  Their only negative point was the same as Lee's, the price is more than double the cost of an equivalent PSU with active cooling.  You have to pay a premium for this type of PSU but it is worth it if you need it.

TR_kigwinstryker500.jpg

"Almost everyone wants the quietest yet most powerful computer possible. Most components generate noise because of the fans cooling them, or because of moving parts. Obviously, solid state drives have eliminated the necessity for moving parts for storage and liquid cooling can replace fans for most components. However, there’s still one pesky component which still generates noise: the high wattage power supply unit. Fanless PSUs have been around for a while, but they’re generally lower wattage and meant for business machines or ultra-efficient HTPCs."

Tagged: PSU, ocz, OCZ ZS series

If you are looking for a really good deal for a power supply, consider the OCZ ZS Series 650W PSU, currently $65 thanks to a MIR at NewEgg.  The price will fool you as to the quality of the PSU, though don't expect perfection at this price point.  The ZS series seems to be a mix of both good and bad, with good efficiency and stable power in all but one condition.  TechPowerUp did not like the low maximum operating temperature and would also like to see longer cabling.   Take a peek at it in their review, but you should probably only consider the PSU at the discount price, there are better alternatives at the full $90 price tag

TPU_OCZ_ZS600.jpg

"OCZ is very busy lately releasing new PSU models. Today we have the chance to test the OCZ ZS 650W. The main difference compared to the bigger ZS 750W, besides capacity, is the reduced number of available PCIe connectors, only two. Like all ZS units it has 80 PLUS Bronze efficiency, its OEM is Sirfa and it uses a non-modular cabling design."

Introduction and Features

Kingwin just released their first fanless power supply, the Stryker Fanless 500W, which is rated for 500W and can be easily overclocked to 600W output with only a slight drop in efficiency. That makes the Stryker STR-500 one of the highest output fanless power supplies on the market today. And the Kingwin Stryker 500W Fanless power supply is certified 80 Plus Platinum with up to 92% efficiency. High efficiency is always good but it is critical for a fanless power supply to help minimize waste heat. Combine that with a good combination of fixed and modular cables and a 5-year warranty and we have a very interesting new product to review!

Kingwin has impressed us recently with several of their new power supplies, most notably the LZP-550W that we reviewed earlier this year, which won an Editor's Choice award. In addition to the new Stryker fanless PSU, Kingwin offers a complete lineup of PC power supplies ranging across seven categories along with PC chassis, external enclosures, docking stations, cooling systems, and accessories.
