Review: Corsair CX Series Modular CX600M ATX Power Supply

Final thoughts and rating

Corsair ably demonstrates that you don't need to spend a fortune on your next PSU upgrade.

PSU manufacturers have played on the fact that bigger is better when talking about PSUs. But the truth is that a modern mainstream PSU has enough clout to power a high-end build, and there's little reason to look past 600W unless you really are running heavily-overclocked systems with multiple graphics cards.

Corsair's CX600M semi-modular supply represents a very good compromise between absolute performance and cost. Available for £60 and able to output above-average efficiency, regulation and ripple, spending substantially more simply results in hugely diminishing returns.

No supply is perfect, and we would like to see Corsair ship an extra couple of PCIe graphics cables, but that's it as far as we are concerned. Corsair ably demonstrates that you don't need to spend a fortune on your next PSU upgrade, and we'd be inclined to put the CX600M on a pretty short list for your next purchase.

The Good

Excellent price-to-performance ratio
Aggressively priced
Solid regulation, efficiency and noise
Flat cabling is a nice touch

The Bad

Could do with two more PCIe graphics cables

For the savvy builder this looks like a good budget choice. Great review Tarinder.

Edit: I didn't see a mention of cable lengths, in case you wanted to add a comment about that?

On paper these PSU's look ideal and I'm sure the handpicked sample sent to you for review performed admirably but, in my experience at least, there seems to be significant manufacturing and/or build quality issues with the CWT made CX range. You only have to look on Youtube or even look on Corsairs own support forum to see people all complaining of the same fault - Coil whine.

That's a really nasty sound! I wouldn't keep using that! I'm sure you'll get a replacement from the nice folks at Corsair. I've handled “quite a few” Corsair PSU, and honestly speaking - I've never heard a coil whine like that. Not even from a CIT PSU! :-)

They did replace it. Twice. Same problem each time unfortunately.

I eventually ended up with a HX750 which is much better all round.

Not sure about these new ones, but aside from the original CX400, the CX range has been an OK range, i.e. should be safe/reasonably stable unlike some no-name rubbish, but really nothing special. A few forum members and myself have been fairly vocal in that a brand which built its reputation on quality parts ends up somewhat abusing that reputation to sell components which, TBH, would probably be considered fairly poor were it from another brand.
