    Corsair RM Series 650W

    Hey all..to start of I'm going to say I am still new to buying components / building computers.

    I am currently in need of a new PSU before I start to upgrade some components, I currently don't need anything more than a 500w PSU but with all the upgrades I'm going to be doing the wattage I need will be raised. I have chosen the Corsair RM Series 650W - I'm wanting to hear if anyone has anything to say about this PSU good or bad, or if there is something that is better, price is fine £80 being max budget. I am wanting the PSU to be quiet and well built.

    Also does the size of the PSU matter at all ? meaning will it fit in my case - CM Storm Scout.

    Re: Corsair RM Series 650W

    According to the thread where you talk about your upgrades, you won't need to increase the wattage, certainly not to as much as 650W. Are there some other upgrades that you've not told us about that will need increased wattage? If so, let us know so we can help you plan better Don't forget that upgrading usually means lowering power requirements as newer components are often more efficient than the ones they replace. In that thread we recommend changing PSU to a better quality model that is more likely to support the better components you're upgrading to

    There are some suggestions in your other thread for recommended PSUs:
    http://forums.hexus.net/pc-hardware-...get-first.html

    Size won't be a problem - they have standard fittings and all normal cases have scope for some depth variation.

    I don't know much about the corsair RM - it's too new to be established as especially reliable or whatever. I think I read that the component choices weren't the best, but Corsair did defend their decision and claim they're using good components in the critical parts.

    If silence is your main criteria then the Be Quiet range are worth a look - they put the budget into nice fans, while other PSUs tend to cheap out on the fan a bit sometimes.

    Re: Corsair RM Series 650W

    I will be honest and admit that i don't like Corsair. Any company that builds their reputation using high quality psu's from the likes of Seasonic and then once established switches to inferior oem's and slashing the warranty, does not deserve my money or support. The RM series were hit and miss in reviews too.

    What i would be looking at right now is the new EVGA Supernova G2 750w gold rated psu. It's a high quality unit built by Superflower, one of the worlds top oem's and is vastly better than the FSP unit it replaced. It has a industry leading 10 year warranty and is on offer this week (until next Wednesday morning) at OCUK for £79.99. It has a single 62.4A 12v rail giving a total of 749w.

    Re: Corsair RM Series 650W

    upgrades I'm thinking of doing
    z87-g45
    I5 4670k
    GTX 770
    Corsair H80i Hydro Series - if I change the case as well(don't like my case) will be having Corsair H100i
    RAM upgrade to 16 not looked into it yet tho.
    also i have 2 monitors, if that makes a big difference to wattage I will need.

    So basicly everything.

    Re: Corsair RM Series 650W

    I own an RM650, but not because it was the best PSU to buy - because it was the only PSU in stock in Maplins when my AX650 stopped working.

    Two things to note: firstly, functionality-wise, I can't tell the difference between it and the HX620. The internal components in the AX650 may well be better, I don't know. I'd usually refer to JonnyGuru or similar, although Jonny is employed by Corsair as I understand it so there is an independence issue on the reviews. Secondly, my AX650 broke, so even if you buy top of the line, it doesn't guarantee it will always work perfectly. Again though, I don't know what exactly broke - perhaps the high quality components in the AX650 saved my rig.

    On a completely separate note, I really doubt that you need 650W. You can run an SLI rig on 500W comfortably, IIRC. I don't have time right now, but have a look on HEXUS for a review of a complete system that's similar to your proposed build, and then check the power consumption under 3D load page. You'll get an idea of how much PSU capacity you will actually need. Don't trust the calculators, the graphics card companies, and random people off the internet (ironic, I know) - they're usually recommending far more power than you will actually need.

    In retrospect, I wouldn't have bought the AX650, but at the time I didn't know better, and I wouldn't have bought the RM650 had there been a lower wattage option in stock.

    So in most cases you're going to be using less power than before, only a bump on the GPU. Monitors don't touch the PSU. 500W will be more than fine - check the reviews (though if bigger numbers make you feel better then by all means get a 650W ).

    Re: Corsair RM Series 650W

    I was thinking of buying a Corsair RM 750 or a Seasonic X-750 for my new PC, but thanks to pastymuncher, I think I'll opt for the EVGA Supernova G2 750W after reading some reviews on it.

    Re: Corsair RM Series 650W

    Good thing about the RM series is that the fan doesn't kick in until its under heavy load, so most of the time it is silent. My RM1000 fan is yet to come on, that's running an OC i7 and an R9 290 playing BF4 and video editing.
    My old 850W PSU sounded like a hoover under that load.

    Yeah it's really nice for the fan not to kick in until under load.
