    Mushkin XP-650 Enhanced Power Supply Review

    Hey folks. I just got Mushkin’s latest a few days ago, the XP-650 Enhanced PSU. This is Mushkin’s first of an upcoming line of power supplies, there will be some nice budget options and some higher-end stuff too!

    I’m going to provide some pics, specs, and tests for you so you can get an idea how this thing looks and performs.

    PSU pics

    First lets take a look at some pics of the unit and packaging:
















    The finish is a glossy grayish-black and Mushkin engraved on the side is a nice touch.

    The cables are decent, especially the power cord. The power cord is very flexible and all cables are shielded to get the cleanest power to your components.

    Specifications


    Size: 17.5cm x 15.1cm x 8.9cm
    Sound: PSU is quiet, I'm not sure of the db rating quite yet, but I'll update when I find out.
    Efficiency: 75%
    Ripple: +/- 1%
    Over Voltage Protection: Yes
    Over Load Protection: Yes
    Over current Protection: Yes
    Over Temperature Protection: Yes
    Short Circuit Protection: Yes
    Cooling: 2 x 80mm silent fan with green color LED
    SLI Support: NVIDIA SLI, ATI Crossfire Certified

    The PSU has four 12v rails and boasts 528W of total power to the 12v. Here are the detailed specs of the rails:



    A few features:



    RailFusion sounded interesting to me so I requested a little more info on how it works. This is the response from Mushkin.
    RailFusion will combine the 12V rails when the current draw exceeds 20A on any given rail. This is to prevent overcurrent shutdown (which plagued many higher-end PSUs when running SLi or CrossFire).
    Performance

    Test Setup
    DFI LP UT NF4 Ultra-D
    FX-57 @ 2.9G
    Mushkin Redline 2GB XP4000
    BFG GeForce 7800GTX OC
    Cooling - custom H20 by DangerDen





    I did a variety of tests with the PSU to see if I could get some rail or vcore fluctuations, however the rails are very solid, < .05% ripple! Used prime to stress the CPU when testing with DMM and speedfan and also ran some tests with OCCT.

    3.3v



    5.0v



    12.0v



    Test Summary




    Unfortunately I don't have a second 7800GTX so can't test the unit in SLI at this time, but I will add some AM2 tests soon. Any questions or requests let me know and I will try my best to get them answered for you.

    wow that gives pcp&p a run for their money. Would be nice to use a multimeter for voltage measurements though software is usually very off.

    I did, see the "DMM" square in the table. Voltages were pretty close to software. I couldnt get DMM to fluctuate hardly at all so either my DMM sucks or its a dam good PSU lol.

    I would like to seem some oscilloscope measurements of ripple..
    Fast computers breed slow, lazy programmers
    The price of reliability is the pursuit of the utmost simplicity. It is a price which the very rich find most hard to pay.

    Modern Ram, makes an old overclocker miss BH-5 and the fun it was

    Me too, but that is a toy I don't have. If I can find a review with oscilliscope tests Ill link it.

    So far Mushkin is looking better than OCZ but more expensive.

    So its Quiet? Is it audible over a 7800/7900 graphics card or comparable to silverstone ps's? This might be my next ps! Thanks for the great review, keep it up!
