Load regulation is within 1% at 12V and 5V, but loose at 3.3V. It is improved at 12V, which is the most crucial rail.

A glance at the light loads table is always useful, as the PSU will typically operate at light loads.

Hi Aris,
Thank you so much for the thorough review
Would you kindly clarify why this 1000W unit didn’t get the recommended badge while the 850W did? I’ve seen other sections where you recommend this 1000W unit when asked about this particular capacity.
Also, I’d like your opinion on this unit vs the RMx at the same capacity. Right now, in my region, the price is +$40 for the RMx, which I don’t mind if you’d recommend paying the extra, but the in-cable caps make it a bit rough on the cable management.
Regards.
Hi!
It didn’t get a recommendation badge because of the not properly set OCP on the minor rails.
Both these units are performance leaders in this category. $40 are a lot, I would go to the be quiet! model which is very good, although the RMx line is among my favorites.
Can you connect this to a GPU with 3x 8 pin PCI-E?
Seems to lack one plug for that unless I’m missing something?
It has 4x 8 pin PCIe so yes
The PowerZone has relatively loud transformer noise, even in standby. You can hear it from the next room. Otherwise, it’s electrically quiet — no coil whine or other weird stuff — but the base hum is quite loud. What about this one?
Can you recommend a power supply that’s completely silent, even in standby? I’ve tested a few and ended up sticking with the PowerZone 2 because it’s a good all-rounder and gets a lot of things right. But that low hum or faint squeal drives me crazy. Every morning I wake up thinking, “Damn, I forgot to switch off the power strip again before going to bed
I have almost gotten Be Quiet Power Zone 2 750 W. I actually have it pending, right now I am considering Pure Power 13 M, as judging by tests it looks quite good.
I returned Thermaltake toughpower due to loud fans even at idle.
Right now I am running Corsair MN750X 750 W and I would appreciate quieter fans. But it is not bad. Also I had not experienced any coil whine, even when trying out uncapped games at up to 800 FPS. But my setup hardly needs 300 to 350 W at max, and does not really strain the PSU.
the Pure Power 13M line is really good. I would go with one of its members.
