    PSU Question

    Hey all, I've got a quick question on PSU's. In my ignorance I built a system a few months using a Coolermaster 650W eXtreme psu, I didn't realise it at the time but the thing is so loud it's beyond belief, so I've decided to buy a new one.

    Anyway, money is a bit tight so I'm trying to find a good balance between power and quality - I've spotted a Corsair HX450 for about £55 but if anyone can recommend any good alternatives (or tell me if that's not powerful enough) that would be really useful...

    I'm currently running a Phenom x3, 4GB, single HD5770 and 2 HD's. Thanks!

    Re: PSU Question

    The Corsair HX450W is a decent PSU AFAIK and also has modular cabling. You could get a cheaper PSU but is modular cabling important for you?

    Re: PSU Question

    Why not mod your PSU? A quieter fan is a cheaper option - but do be very careful (electrocution hurts) if you decide to do it. If you're at all unsure then don't..

    Re: PSU Question

    I do like the idea of having modular cables, especially as I'm not actually running that much. I did look at the regular Corsair VX which was only a few pounds cheaper but the length and number of cables looked a bit like overkill for me and would have been pretty messy.

    Edit - I did look at the option of putting a new fan in, but to be honest I don't think I'd be confident enough!

    Re: PSU Question

    For you setup I don't see why a Corsair CX400 won't fit the need. It is very similar to a VX450, not sure about the noise level though.

    You setup shouldn't take up more than 200W so there is plenty from a 400W PSU.

    The hx450 was a great low wattage modular psu, I'll never understand why corsair stopped making it.

    Re: PSU Question

    I have the non-modular VX450 and even in a medium case like the Antec 300 it takes a lot of planning of what component to place in what order to have any semblance of neatness but as a PSU it’s great in terms of stability and build quality. Noise wise it is about on a par with the CPU fan so doesn’t stand out but isn't really quiet either.

    Weird, SPCR rated it as one of their quietest-ever PSUs here: REVIEW. I quote: "Like the HX series, it's among the quietest fan-cooled PSUs we've tested" but there are caveats: "Ensure that the PSU intake air does not exceed 30°C often, nor demand more than ~300W DC output". Full review gives a very complete picture. I'm happy with mine!

    I'm using the Corsair HX450 in this rig (Poseidon Magma in sig). CPU is OC'd to 3ghz instead of 2.9 though and last time I checked, it drew just a smidgen over 200watts from my watt-meter.

    Fantastic PSU imo.

    I owned it before and I can tell you it's absolutely silent. You won't be able to hear it over other case fans.

    Re: PSU Question

    Hiya,

    I'm using a Corsair CX400 - whisper quiet - really. Occasionally you hear the fan spin a little faster if it gets a bit warm for a couple of minutes, then back to whisper quiet. To be honest, the other fans in the computer would drown it out! I'm using it on a low-spec cool-running computer, and the only other fan is the CPU fan - you barely know its on.

    Cheers.

    Re: PSU Question

    Nice one, thanks for the replies. I think I'll treat myself and go for the HX450 if it's still in stock at Scan.

    Re: PSU Question

    I highly recommend the Corsair HX series. My last PSU was a Corsair HX520 that I had for 3 years. It was a solid PSU that was made by SeaSonic OEM. SeaSonic is renown for silent power supplies.

    The fan started going on my HX520, I run my PC 24/7. It was a slight rattle. The PSU was still covered under Corsair's warranty so I did an RMA. Corsair sent me a brand new (not refurb) HX650, also made by SeaSonic OEM.

    So kudos to Corsair for ultra efficient and quiet PSUs and two thumbs up for their warranty.
