  3. AMD Ryzen Core P5 Build

    Finally upgraded to AMD Ryzen. 

    I was a long AMD fan till Phenom X6, but due to reason known to everyone have to switch to the blue team. But AMD is now back in action with Ryzen and mostly all RAM related issues have been ironed out. So I think this is the best time to upgrade. My last PC was an Intel i7-7700K based system and for this build I am going with AMD Ryzen 1700 CPU with custom liquid cooling. 

    Hope you all like the build.

    Making of Vertical GPU mount
    As we all know the Thermaltake Core WP100 Super Tower Chassis don’t support vertical GPU mounting. But in my SUPERBUILD I want to install GPU vertically with hard tubing liquid cooling solution. So need to make a vertical GPU mount for this case. 

    85.jpg

    86.jpg

    Will be modding old motherboard tray for PCI-e mounting plate and use PCI-e riser cable for graphics card installation.

    Vertical GPU Mounting bracket is done. Next have to cut few holes in the case back panel for installation of this bracket.
     


  5. 13 Nov 2017

    PSU for the project arrived. Thermaltake Toughpower 1250W RGB PSU, a huge 1250 watts 80 PLUS Titanium power house, best suitable for this build. 
    Fitted the case with four LCD thermometers for monitoring temperature of different segments of Phase Changer section. Also started working on custom liquid cooling for the GPU.

  6. The "SUPERBUILD" Case Mod

    Hello to all, 
    As most of you know, in year 2011 I build a “Phase Changer Rig” . An extreme overclocking rig. Capable to cool down the CPU below -38C. One of its kind in India.

    01.jpg

    It was a complete scratch build using MDF board and aluminium square rods.  Till date case is in good nick, only thing I did wrong was not to cover sides of lower phase changer section. 

    Nothing bad, but recently due to absence of the side covers I accidently mange to damage the condenser and brook a copper tube. Resulting in a complete failure of the phase change unit. 

    Now this has to be fixed. But this MDF case is about six years old, so I said to myself the fixed phase change unit defiantly needs a new and safe home now.  So my hunt for a suitable case began. 

    As I have recently worked with few of Thermaltake cases, the first option came in my mind was the Thermaltake Core WP100 Super Tower Chassis.  A two chamber case perfect for my needs. 

    02.jpg

    After going through the datasheet and checking dimensions, the Thermaltake Core WP100 Super Tower Chassis fits best for this super build giving new life to my 24/7 extreme overclocking Phase Changer build. 

    I called the new Case build as SUPERBUILD. Where CPU will be pushed to extreme limits at sub-zero temperature and I will also overclock the GPU using custom liquid cooling . So this build will be a super overclocking beast. 

    Like to thanks Thermaltake for supporting my idea and the build. 

    First the Thermaltake Core WP100 Super Tower Chassis arrived in two big and heavy boxes. One box had the Core W100 and other the Core P100.  Both are individual cases by themselves, but stacking them together makes the monster Core WP100 Chasis.

    05.jpg

    Now let’s un-box the cases. We start with Core W100.

    19b.jpg

    Case build experience with Thermaltake Core W100 Chassis is unique as this case is not like other cases in the market. As mostly all Pc cases are pre factory build and came ready to be used out of  the box but not this one.  Thermaltake Core WP100 Super Tower Chassis comes in de-assembled bits and pieces, with proper labelling and complete build guide. So one have to assemble this case piece by piece.  A total do-it-yourself experience, a priceless experience for me. 

    Beside all side panels and structural parts, the Core W100 case comes with a big accessories box, with lot of screws, for build the case together .

    Now repaired the phase changer unit. Replaced the condenser coil and re-filled the gas. Tested all working fine again. Now started installing the phase changer unit in the bottom section of the case i.e. P100. Everything fits perfect. Now next step will be installing a new controller and re-doing of all the wiring and all new Neoform insulation part.

    Waiting for some parts to arrive. Will update more 

    Thanks.


  7. Core P5 case is one of the most popular case globally in Liquid Cooling and Open frame type case lovers.

    Being one of them I also like this Core P5 case, due to its special 90 degree GPU mounting capability.
     But dual graphics cards setup was difficult and especially I don’t like the graphics card bending and hanging by the PCI-e slot on the motherboard.

    So I planned to change the case orientation and here it is an Un-boxing with my mod of Core P5 Case.

    600 Watt budget PSUs Battle

    Corsair VS650  - vs - Cooler Master MasterWatt 600  - vs - Antec VP650

    PSU_600.jpg

     

    I have reviewed few PSUs in past two years or so mostly all were higher end expensive computer PSUs and I am constantly asked by many to suggest a budget gaming PSU or review one.  I have few budget PSUs with me and was for long willing to test them but didn’t have a good idea or inspiration for an article.

     

    But recently I got news about Cooler Master’s new PSU lineup the “MasterWatt†and “MasterWatt Lite†series of PSU, offering new design and features with improved performance and reliability. I was more interested in MasterWatt Lite series as they would be having lower price spectrum. I contacted guys at Cooler Master India to confirm and was surprised to know that MasterWatt Lite 600 is indeed a under Rs.5K price tag product. 

     

    600 + watts and with a under Rs.5K of price tag, is the PSU every budget gamer or pc builder looking for. This gave me an idea to do a comparison between PSUs with 600 + watts of power and are under Rs.5K. I already have Corsair VS650 and Antek VP650 with me, and when shared the idea with Cooler Master India, I also got a sample of Cooler Master’s MasterWatt Lite 600 PSU. 

     

    So now about this article. This comparison is not about the marketing features of these three PSUs (For that you can find respected product links at the end of this article), but rather about the features, product performance and reliability which is more important for a budget buyer. 

     

    I will be doing a detailed inside-out run on these PSUs and will be giving each a point (at a scale of 1 to 5, i.e. BAD to GOOD, not EXCELLENT as these are budget PSUs) at every segment of this article.  In the end we can club these points together to find which PSU is best among these… Simple.

     

    Now let’s begin the comparison.  

    01.jpg

     

    Product looks and details

     

    What you get out of the box.

    All PSUs comes in a cardboard box with PSU, manual and decent AC power cable. PSUs are build with requisite quality and thickness of iron sheet for rigidness and minimization of interference.     

    02.jpg

     

    All three PSU are having a 120mm fan for cooling and a power ON/OFF switch along with Main IEC power connector. 

    03.jpg

     

    SCORE

     

    Corsair VS650 = 5

     

    Antec VP650 = 5

     

    Master Watt 600 = 5

     

    -------------------------------------------------------------------------------------------------------------------------------

     

     

    Cables and Connectors

    04.jpg

    All PSUs have decent 18AWG cables. Among all three, Antec cables was little stiff and Corsair is having full single braided cables. As per connectors, beside 24pin ATX,  8pin CPU and (1 by 2) 8pin PCIe connectors Corsair is having 4 Molex and 3 SATA connectors, Antec is having 3 Molex and 6 SATA connectors. Finally Cooler Master is having 4 Molex and 6 SATA connectors 

     

     

    SCORE

    Corsair VS650 = 5

     

    Antec VP650 = 4

     

    Master Watt 600 = 4

     

    -------------------------------------------------------------------------------------------------------------------------------

     

    Inside looks and Components detail

    Now let’s open these PSU to see what all they have for us. Note very few of PSU brands manufacture their own entry level PSU. Here only Cooler Master manufactures it’s MasterWatt PSU, remaining two are OEM. Corsair have CWT as OEM and Antec goes for Delta Electronics. 

    05.jpg

     

     

    Component details are segregated as following. 

     

    Transient Filter stage

     Transient filter starts right from the IEC connectors via wires wrapped around ferrite ring to the PCB (Corsair is have a separate ferrite coil on the PCB) fulfilling all the transient filtering needs, components namely two CM chokes and two pairs of X and Y caps. Unfortunately there is no MOV (Metal Oxide Varistor) present on the Antec PSU, so this PSU is susceptible to spikes coming from the power grid.  

     

    06.jpg

    07.jpg

     

    SCORE

    Corsair VS650 = 5

     

    Antec VP650 = 3

     

    Master Watt 600 = 5

    -------------------------------------------------------------------------------------------------------------------------------

     

     

    PCB

    First look on the PCBs gives an impression that the build quality of Antec seems to be very good, but later found Antec to have the thinnest and poorest PCB. When I started de-soldering the components off the Antec PCB whatever low temperature I tune on my soldering iron, the copper traces pops off with the components on Antec PCB. So I decided not to de-solder any components off Antec. Too bad. Remaining two PSU have good quality PCB.

    Antec VP650 = 2

     

    Master Watt 600 = 5

    -------------------------------------------------------------------------------------------------------------------------------

     

    MAIN Bridge rectifier

    Both Corsair and Cooler Master is having the same GBU606, a 6amp bridge rectifier, where as Antec is having 8amp GBU8K bridge rectifier that too on a separate heatsink. Though at 600W loads cooling of bridge rectifier is not needed, but extra cooling is always welcome.  

     

    14.jpg

     

    SCORE

    Corsair VS650 = 4

     

    Antec VP650 = 5

     

    Master Watt 600 = 4

    -------------------------------------------------------------------------------------------------------------------------------

     

    MAIN Primary Capacitor

    High voltage DC from Mains AC is filtered by big hold capacitor in a PSU. This is one of the key component depending for smooth DC-DC conversion. And this is most likely the top most candidate responsible for any PSU failure. 

    I am personally disappoint to have a 85C ratting main cap on all three PSU, although 85C is doing the job, but please a 105C rating main cap is the best.

    Below table give the technical details of each cap, giving us an idea about its quality and help in giving points. Beside all the datasheet figures, I know with my last 12 years of electronics experience the Elite cap are the most busted caps I have seen among these three.

     Antec and Corsair used similar type of chip for their Stand-By segment. TinySwitch Single chip Switcher solution, which incorporates High voltage MOSFET and control circuitry on one dye.

    Secondary Schottky rectifier

    All PC Switching mode power supplies uses dual center tap Schottky rectifiers in secondary stage and even installed in parallel to double the current handling of the DC- DC conversion. 

    We will judge the PSU according to the total Ampere ratings of the Schottky rectifiers for each DC rail output.

    Antec ** Secondary Schottky rectifiers can’t be de-soldered due to poor quality of Copper trace bonding on the PCB.

    Cooler Master Secondary Schottky rectifiers

    All 12v and 5v Schottky rectifiers are having small green ferrite rings over the DC output leads. This helps in filtering out the high frequency edge off the DC rails and improves ripple management. Great job Cooler Master for this.

    Secondary Filter Caps

    These PSUs are designed for budget market, so you will get decent brand caps at secondary filter stage. 

    For decent filtration minimum of 2200uf filter caps should be used in DC-DC convertors. So we will judge this segment according to total capacitance on each voltage output. 

    All secondary caps on these three PSUs are 105C rated.

    Antec Secondary Filter Caps

    Being this a budget unit I was first surprised to see a Solid Cap and premium Japanese Rubycon Caps on Antec PCB. But looking closely found that the solid cap and Rubycon Cap were just installed on 12V rail and remaining 5V and 3.3V was having Taicon and LTec caps. This is weird, its seems like these premium caps are installed for a reason or better say a “PATCHâ€, as later I notice significantly high voltage ripple on 12V rail. It seem engineers were trying to fix high ripple issue due to some design or PCB layout fault, but still problem is not fully rectified. Hmm ..

    Cooling

    For cooling solution all three PSU have a 120mm fan

     

    Corsair – FAN

    32.jpg

     

    Antec – FAN

    33.jpg

     

    Cooler Master – FAN

    34.jpg

     

    Speed of fan is controlled via a simple thermostat and power transistor circuit. For fan to react according to the internal temperature thermostat should be properly installed onto the heatsink. Both Cooler Master and Antec have done it right, but unfortunately that is not true for Corsair.

     

     

    Corsair

    Below you can clearly see that thermostat is just soldered onto the PCB and is having a gape of about 1-1.5mm from secondary heatsink so real temperature is never registered by the thermostat and fan will not ramp-up when needed the most.  This results in higher junction temperature on power devices and over all higher operating temperature of the PSU, lowering the overall PSU life and I think this is the main reason of high failure rate of this PSU.

    Load Test

    To test the PSU on my Active load test, I have manually increased the load in Amps on 12v first rail, 12v second rail, 5v and 3.3v rail to simulate 100%, 80% 50% and 20% load. Since this PSU is having only single 12v rail, so divided the load in half on both 12v loads on my tester.

    5V stand-by and -12V supply was left at a constant 0.5amp load throughout the test run.

    Maximum theoretical load handling capacity of my tester is somewhat around 1500W, but due to MOSFETs safe operating area (SOA) characteristics and thermal load handling capacity of the heatsinks, this tester can handle Max 1300W.. For safety reasons I have also installed a thermal controller which turn OFF the attached PSU if temperature exceeds SOA specifications.

    Over Load Run

    During this test we try to pull more than specified power of the PSU. So at certain point PSU should turn OFF by itself showing proper working of Overload protection or should die showing absence of any protection.

    Below is the absolute Max power we were able to pull from these PSUs.

    Voltage Ripple

    We measured range of ripple using oscilloscope at maximum rating of the PSU for 12v, 5v and 3.3v supply output in Pk-Pk(mv).

    -------------------------------------------------------------------------------------------------------------------------------

     

    There not much to say now, the final scores is self explanatory. Still considering the price, Cooler Master’s new Master Watt Lite series PSU is definite a game changer in the segment and will create a good competition and may inspire other brands to redo their budget PSU segment. Which is actually good for the market as latest graphics cards are becoming more and more power efficient, a 600W PSU is sufficient for mostly all single card gaming build and if we get good price to performance ratio from a product it’s always welcomed.
