Seasonic M12 600w Modular PSU

Connectors

The modular power supply is one of those inventions that has the PC enthusiast communities split down the middle. Some think that the modular design is a great design - keeping the inside of your PC tidy while also maximising airflow. Others believe that it is unreliable and can cause increased resistance where poor connectors are used. In the end it really comes down to the quality and type of connectors the manufacturer has adopted for the unit and how well they have implemented the design.

Seasonic M12 600w Modular

Seasonic have gone for their own proprietary 5-Pin flat connector design for use with the Molex and SATA connectors, but have stuck with the tried and tested 6-Pin PCI-E style connectors for powering the PCI-E cables. On attempting to plug in one of the SATA cables I encountered an issue where the connector backplane was able to flex, and thus prevented me from inserting the modular cable. A video recording of the issue can be seen here.

After further investigation, I managed to find the cause of the issue. The backplane had been designed to sit in front of a lip on the bottom of the power supply casing (as can be seen here), but somehow had managed to come loose. This may well be an isolated issue, but it would be good to see a more sturdy design implemented as the connectors are often subject to a fair amount of abuse.

Seasonic M12 600w Cables Seasonic M12 600w Cables

A total of 9 modular cables are included in the box, but it is worth noting that only 7 of these can be plugged into the unit at any one time, leaving two of the cables redundant. All connectors on the M12 are finished in black, with the molex connectors adopting the 'easy grip' design. It's also good to see that Seasonic have decided to sleeve all cables right to the very last connector.

As the use of floppy disk drives is now declining, the majority of us no longer require floppy style power connectors and would rather an extra Molex or SATA connector instead. Seasonic have realised this, and decided to make the usage of floppy disk power connectors optional by supplying them on a separate Molex-to-Floppy extension cable.

Seasonic M12 600w EPS12V Seasonic M12 600w ATX

The ATX connector on the M12 is native 24-pin. However, as you can see above, a small block of 4 connectors can be broken off to switch the connector to 20-pin, and thus make it compatible with older motherboards.
As many motherboards still make use of the P4-12v 4-Pin connector, Seasonic have chosen to include two separate cables for P4-12v (4-pin) and EPS12v (8-pin) standards.

"Seasonic are known for their range of silent and stable power supplies. The M12 is one of their latest models, and their first entry into the modular scene. How does it perform? We find out..."

I look forward to the Corsair 620 review if you get to test one, as far as I know it's very similar but is quieter with only 1 120mm fan.

I look forward to that with massive interest, I'm thinking of getting one because of it's supposed high efficientcy and quietness, may I ask if you sell them after review?

Nah, we either keep them for future comparisons or send them back.

Nice review

You need to upgrade the PSU tester, 10a per 12v is nothin!

It can do up to 80a total on +12v at 5a increases.

If you look at the specs on the M12, the maximum combined amperage it can cope with on the +12v rail is 48a - so i got as close to that as possible (40a). Plus its handy to compare results with other 600w PSU's - most of which have been subjected to the same stress.

Wow, 80a? Impressive.

Thanks for explanation though XMS

Great review, and this looks to be a half way decent PSU. I think I could pick something better to put in my case if I had the choice however.

XMS, you gotta line up a single rail 1kw turbo-cool review!

I am not a fan of the modular style PS.

But that was a very good review.
