    Don't see why not. Do you have any concerns in particular?

    Absolute overkill if that is all your system will ever be.

    Re: Corsair Psu

    I realise it doesn't answer your question, but I would advise you look at PSUs by companies that make decent PSU's like Antec, Cooler Master, EVGA, Fractal Design, Rosewill, SeaSonic, Super Flower, Silverstone and Thermaltake. They're much less likely to break or develop intermittent faults. Oh, and NO COIL NOISE (not that the RMX series suffers that)

    Re: Corsair Psu

    750W for a HTPC? That's not a good idea. PSUs need to be under load to be efficient. You're probably not going to break 200W on that setup.

    You'd probably be better off with something like this: https://www.scan.co.uk/products/300w...mm-fan-atx-psu

    Re: Corsair Psu

    Yes, 750W seems like overkill, my i3 Ivy, HD 270 3 drive HTPC/TV gaming rig has one of these (Maybe the earlier model. It only has 1x 6-pin GPU power connector, if it had a 6/8, I'd happily run my 970 in it.), I got it for ~£44: https://www.scan.co.uk/products/360w...lent-fan-dc-dc

    See http://www.realhardtechx.com/index_archivos/Page362.htm - a 500W PSU is recommended for a PC with a R9 270X

    Then see http://www.tomshardware.com/forum/id...#xtor=EPR-8886 for different levels of quality power supplies. I'd aim for a tier 2 or 3 PSU for a HTPC. eg Seasonic G series 550 https://www.amazon.co.uk/d/lm8/Seaso...ply/B00918MEZG

    Re: Corsair Psu

    RealHardTechX's 500W recommendation for the R9 270X will be conservative to ensure that you don't run out of juice - there is a large safety margin as this can only be a general guideline that doesn't take into account the specifics of your build and your usage scenarios.

    They recommend 500W for my HD6850 (OC 950Mhz) but I happily run it on a 400W PSU with no problems. Even with the system maxed out (100% load on CPU & GPU using scientific workloads, and 6x 3.5" HDDs active) it draws 260W measured at the wall. I can force it to draw 345W briefly in the worst case scenario of spinning all 6 HDDs up simultaneously from sleep (this I have to contrive as by the default the system staggers the drives); this too is measured at the AC input, so I make that a 300W DC load, which is only 75% of the 400W PSU's rated output. However, this system spends most of its time near the 100W mark, which is inside the region of decent efficiency for a modern 400W PSU.

    Choosing a 500W PSU will be OK; you'll be assured of having enough power should you upgrade your components to higher models in the future, which in general is not a bad approach as normally one should try and invest in a quality PSU and keep it through multiple upgrades of other components. 500W+ PSUs also tend to have a good selection of PCIe and drive connectors which can be handy or a hinderance depending upon your build (though you could spend the extra for a modular cable PSU).

    However, for the specific HTPC use case on the OP, they could choose to use a PSU that's in the 300-400W range too; the advantages here are that for the same amount of money you can get a better quality of PSU - with improvements not just in efficiency, longevity and protection, but noise which is usually very important for HTPC use. You'll also be better matching your power draw to the most efficient region of operation for the PSU, so you won't be burning watts needlessly through over provisioning. The drawbacks are that you (usually) won't have as many PCIe and drive connectors to play with, but for HTPC this is not a problem. Consider also that these days both CPUs and GPUs are tending to get better in power efficiency - the days of ever increasing TDPs for mainstream CPUs and CPUs are well over.

    Re: Corsair Psu

    I'm currently using a 500 watts corsair. I'd say total power output of my system is well under 200 watts. R9 270x is about 180 watts at the most.

    Re: Corsair Psu

    I try to plan so that -
    1) my average power consumption is half of the PSU rating and
    2) my max power usage is less than that of the PSU rating.

    get an evga ...
    had corsairs think it was 3 that went in 7-8 months .. ball ache to get it replaced .. theres a long forum thread somewhere ...
    got an evga .. 6 weeks ago it went pop after 14 months .. 15 mins later I had an email to send it back to a uk address 4 days after that a new one turns up at my door .. nuff said

    The Corsair CX were pigs - dying everywhere (bad caps). Newer models seem to be pretty good.
