    I am in big dilemma now, I wanted to get RM750 for my PC but its currently out of stock in most places, so looking at RM650, it will be fine for my current system but not sure it will be enough for any future upgrade or not.

    I will never do SLI or cross-fire and will never get any very high end GPU, so wondering is 650 watt enough for normal gaming PC??!!


    Please advise...

    Thanks!

    The corsair AX series however is a different kettle of fish :D. Seasonic KM3 platform.

    The AX is Seasonic and doesn't have the corsair link monitoring software. The AXi series are made by Flextronics. Personally I see the corsair link stuff as a gimmick. If it was my money I would stick with the AX series.

    My heart is on the AX860 at the moment. I just need save a little more :D

    650w is plenty for normal gaming PCs without Sli or X-fire.

    Consider the Cs650m?

    Oh dear. I wish I knew that they weren't too fantastic before I bought mine back in February. I've got to be honest though, I've not had any trouble with it yet and I've put it under very high loads. It did get quite warm though which didn't happen with an Enermax PSU I had previously.

    Jonnyguru's site didn't seem to think it was the end of the world when they reviewed it. I'm unsure what to think.

    Hmm. They're a very reliable PSU testing site too.

    Honestly, I've blasted mine for prolonged periods of time with two heavily clocked 6950s (@6970s at times) and an overclocked 4770K at 4.7GHz. It has yet to show any bad signs.

    I'll just throw this out there now, but based on what's quoted above anything over 500W is likely to be unnecessary. My money would be on finding a quality unit in around that range - you'll get better stability, acoustics and efficiency than you would with a "branded budget" model like the RM series.

    My sig rig has never pulled more than 350W from the wall, and both CPU and GPU are overclocked.

    At the end of the day Corsair supply a 5 year warranty on them, so they must be confident of the build quality.

    i am putting that to the test right now.
    sending in my TX 650v2 after 2 years. i was always wondering why my "silent" case was louder then the rigs of friends. the fan of my corsair psu runs as if its under full load, all the time, making 48-54db. i dont really consider that "ultra silent" as stated on the box it came in. And i dont seem to be the only person on the net having problems with corsair psu's (loud fans, coil whine) but atleast, the customer service has been forthcoming until now.

    I agree with this. 500W in your case is more than overkill!

    This will do for you and only £52.20

    Corsair CX500M PSU And as it's Scan, you get free next day delivery too for being a member here!

    That's exactly what I'm using, although I got it on sale from Maplin of all places for £39.99 :thumb:

    It's not the quietest thing in history but it works flawlessly and I don't notice it over the hum of my 770 at load.

    Indeed they do - although I suspect the PSU in your next rig will have a bit more hair on it's chest than a CX!

    Just to let you know all that I ordered AX760 from Amazon last night, it may be more that I ever need but at least i don't need to worry about quality or my future upgrade.

    Also I actually ordered the last one, its out of stock now, glad i did it in time :D

    And big thanks to you all for everything :thumb:
