Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

520W Seasonic M12II EVO Edition, Full Modular, 80PLUS Bronze, SLI/CrossFire, Single Rail, 40A, 120mm Fan, ATX PSU is rated 4.3 out of 5 by 3.
Rated 5 out of 5 by from Good quality PSU from a very reputable manufacturer I purchased this PSU to replace my old Antec Neo 550 PSU, as the power socket on it fouled the case. Luckily the socket on this PSU didn't cause the same problem. The unit is well built, and comes with a large array of cables that should cover a well equipped system. Also, being fully modular, you can replace a cable should it get damaged. My only negative comment on this PSU, would be the flat cables. This is because they can be a bit of a pain to route, which is definitely something I found easier with the braided cables on my old Antec PSU. This can be remedied however, by purchasing aftermarket cables, which are generally individually braided, and very easy to route. These are also good if you want the inside of the PC to look good, as various colour options are available online. Overall, I would definitely recommend this PSU. I have not owned a Seasonic PSU until now, but there is definitely an element of quality with it. I have no doubt it would power a good spec'd system, without breaking into a major sweat. Of course as with any components, check compatibility, number of connectors etc. before buying.

Rated 4 out of 5 by from An excellent value, fully modular PSU. I have previously bought Corsair CX-series for my desktop builds, but was reccomended Seasonic as they were listed as a Tier 1 PSU. A £60 500W fully-modular power supply is a pretty good introduction for me, and I was quite impressed. Fully modular is a definate advantage, but be aware the secondary power connector for the motherboard has 2x 4-pin connectors, so if you only have one 4 pin connector it will leave a connector flapping about. Apart from that, it's quiet, it runs the 230w R9 380x without issues, and I'm pretty happy with what I got.

Rated 4 out of 5 by from Great PSU! I brought one of these for a customer’s PC and what a great little thing for the price. The power supply looks nice and performs to that as well. As it’s a Seasonic I trusted it as they OEM a lot of PSU for the different manufactures and it lives up to that reputation. The only gripe I have with this unit is the 20 + 4 pin connector for the motherboard as it and normal mesh type sleeving. This makes the connector really hard to bend and bit of a battle to get into the motherboard end but this a recurring problem for most PSU's. But other than that one issues a great unit and the flat black un-sleeved cables for the rest of are great and a breeze to cable manage. Great unit form an ever reliable manufacturer.

Questions & Answers

Is this PSU compatible with Haswell-era CPUs?

Asked by: WattsvilleBlues
Yes, absolutely. It would do the job very well. Just be sure to check ratings if you are going to be using a high model i7 and a powerful GPU(s).
