OCP is sky-high at both 12V rails, in reference to the official specs. There is no point, if you ask me, in having a two-rail design if you need to set OCP such high to cope with power spikes; better use a single 12V rail and get done with it. OCP is also high on the minor rails, with no reason, especially at 3.3V. Thankfully OPP is appropriately set, effectively protecting the PSU. The other protection features are present and work well.

Aris, will you be doing a review of the be quiet! Straight Power 12? I’d like to buy the 850W version and I’d love to know your opinion of it.
Trying to find some time to handle them 🙁
Pure Power 12 M or Thermaltake GF3 at same price? Thanks Aris!
I should add that I also value customer service and RMA simplicity in Europe, tbh I only heard bad things about TT support and good things about be quiet, which could flip the balance even if TT GF3 is the better unit.
Just a note on this PSU – the 24pin ATX Power Cable is only 550mm long so can be a very tight fit in a mid sized case like the Phanteks P600S.
Indeed, it should be 600-650mm ideally.
Hi aris, are these non japanese caps enough to discard the psu considering the overall performance? It’s the cheapest atx 3.0 psu in europe, rmx shift and toughpower gf3 are 50€ more expensive.
If the price difference is that large, go for the be quiet! unit. These guys seem to trust it a lot, to give it such a long warranty, after all.
Does this review apply to the 1000 watt version too? I’m not very knowledgeable so I don’t know if quality varies a lot between versions.
Yes it uses the same platform so quality wise it will be identical.
I wish you could review the MSI MPG A850G PCIE5 psu which is the closest competitor in terms of price and specs.
If MSI decides to send it to me, sure why not!
After having coil whine on Vertex Gx 1200 which i paid 350 EUROS i bought the Be quiet 12M 1000w 205 Euros for my rtx 4090 and there is no more coil whine or buzzing in sleep or idle.
Im happy with it for now.
Solid work as always Aris. Thanks (:
