    Default Extra laptop PSU

    I'm thinking of getting a second PSU for my CQ60-420US, as I'm pretty consistently running out of battery before my classes are done for the day. Is it worth it to buy another HP unit (model 463958-001), or are any cheaper third-party units decent?

    If you can get an aftermarket one for less, get an aftermarket one. I have a unit with universal tips that cost half as much as a factory replacement and it's just fine.

    Just be careful with the realllllllllllly cheap ones. Certain notebooks will power with them, but won't charge because of the lack of a little IC that companies like Dell put into the notebook adapter.

    Thanks, Jon. One question, I know that with desktop units, the computer will only draw what it needs, but with laptop units, do I need to worry about matching the wattage? It's a 65-watt unit, and most of the universal ones I'm seeing are 90-watt.

    A laptop power supply is an SMPS like any other. All you have to do is make sure that the one you get is rated for an equal or greater power output than the one the laptop came with.
    Main: i5 2500K@4.6GHz w/Zalman CNPS10X Performa, Intel DZ68BC, 8GB G.Skill DDR3-1600, PNY GTX 470 + EVGA GTX 470, ASUS Xonar DX, ADATA S510 120GB, Samsung 1TB F3+1TB F1+2TB F4, Kingwin LZG 1kW, Lian-Li PC-9F, Dell U2212HM+S2209W, Win7 Professional.
    Laptop: Dell Vostro 3450, i5 2410M, 8GB DDR3-1333, AMD Radeon HD 6630M 1GB, Intel X25-M 80GB, Seagate Momentus 750GB, Win7 Home Premium.
