Got 2x 600w M12 over a year ago for around £100 each bundled with some icybox external caddies (that I sold on for about £20).
They're good enough units. Neither of them liked doing a 8 pin pcie adapter for a gtx280 tho, wouldn't even start it. Had to use a 500w pc&p.
I'm happy to see they've changed the modular banks to reflect 2x 8 pins in this model, as the majority of us would realize, it should be 'capable' of 4x 8 pin pcie (even with 2x adapters) - it would have been interesting if it would work considering my previous experience.
I'd like to see more variety in the ability to customize modular connections as a result.
Classic review once again, £150 is quite steep tbh.
Not always mate. Different PSU's have different efficiency curves. Most of the time efficiency peaks at around 50-75% load, but I've seen some PSU's hit their highest efficiency at close to 100% load.
