Style Name: Fixed CablesSize: 750W Verified Purchase
Cables are minimum 600mm long with the floppy cable reaching 760mm. So plenty of length here for a tower system.
Main connector 24 pin ATX
1x 8pin cpu power connector (8pin/4pin - it splits for compatability)
4x PCI-express cables (8pin/6pin - 2 split off if needed) (I needed 2 for my card so this allows for an sli expansion later on)
8x Sata connectors
6x peripheral 4pin molex style connectors for drives/fans etc.
2x floppy connectors (going unused by me but still useful to have)

+3.3v @ 25A
+5v @ 25A for 130W across 3.3v and 5v combined.
+12v @ 62A for 744W max (Very nice for even the most demanding graphics cards)
-12v @ 0.8A for 9.6W
+5Vsb @ 3A for 15W

1 mains power cable (3 pin uk) with molded plug + fuse
A bag of black cable ties for tidying up your new cable jungle.
4 screws for mounting the psu.

It went in without a bother and is quieter than my case fans.
I give this 5 stars because this is a bargain (currently 30% off rrp) for what you get from a quality maker of hardware plus this is 80+ Bronze efficiency rated and comes with a 3 year guarantee .
This has more cables and power than I currently need so plenty of room for later expansion.
I was considering the 600w cable management version but for the difference of a few pence it was silly not to get this one.

For something that is attached to all your hardware and a critical piece of kit, you do not want to skimp on quality with a psu, it is worth it for having peace of mind rather than the false economy of buying some cheap high wattage psu that could fail in less than 2 months.

Style Name: Semi-Modular CablesSize: 600W
As a computer technician and part-time system builder i purchase on average around 50 power supplies each year and the CX600m is my go to power supply. If i have to replace a power supply in an office computer or low/mid end gaming system then this is the one i usually recommend to people, naturally that also depends on what (if any) graphics card you use or plan on using.

With the TDP (watt usage) of many computer components coming down each and every year the need for 800W+ power supplies is reducing year on year and we have now reached a situation where you can run a high end gaming system off a 600W power supply (depending on the parts you use). This power supply offers a dedicated single +12V rail which will be compatible with most components. I also like that the cables are fully-sleeved which keeps everything looking neat and tidy and for those that worry will the cables reach in a full tower (E-ATX), the cables are extra long so they will fit even the largest of cases.

Being a Semi-Modular power supply means aside from the two motherboard connectors 1x 24pin and 1x8pin (which can be split in half if your board only requires a 4pin) all the other cables can be plugged in as and when you need them which makes installation ten times easier and also means you don't have spare cables around the back which in turn makes cable management a breeze especially in smaller mATX cases.

Verdict: Good quality Branded Power supply which comes with all the cables you could possible want, being a semi-modular design simply makes it easier to handle and install, Bought many of these over the years and if you are looking for a 600W unit then i honestly wouldn't bother looking at anything else especially when you consider Corsair include a 3 year warranty! Recommended!

Style Name: Fixed CablesSize: 750W Verified Purchase
My PC was a home build bare bones Core i3 2nd generation, with an Asus motherboard. I do not put it to very demanding tasks, but had some very annoying issues. The first being the refusal of Media player to play videos properly, but some would play normally. The second issue is that the PC would boot normally on about half the occasions it started it up, but on other occasions it would show the BIOS screen, giving a message that a new CPU had been installed. This was not the case, it had just lost all the BIOS settings. This became annoying very quickly. I changed the battery, upgraded the BIOS and tested the PSU and tried the video card in another PC, but nothing fixed this issue. I was googling the issues one day, to try and find a cause and I saw a recommendation go check the Asus power draw website, based on the components. I did this and it came out at 650 watt, which was a bit of a shock, as I had a 550watt Corsair. I decided to gamble on a more powerful PSU and opted for this one. The existing Corsair was given to me and the most I had for a previous PSU was under £30, of paying two and a half times as much was a bit of a gamble. The PSU arrived quickly, had loads of connectors and appears to be of good quality. I fitted it and I am very pleased to say that I have a BIOS that no longer forgets and all videos now open! I did not realise that such a difference would be made. Also, my PC now feels noticeably faster and a good bit more responsive - not sure a PSU can do that, but if a PSU cannot make that difference, then it is just a coincidence. I am delighted with the results and I do not begrudge paying a good bit more than I would do normally for this very good PSU. Very highly recommended, as a bonus. it is not too noisey either.
