On one of the fanless nightjars I researched, the review stated that is OTP is faulty and doesn’t work, but it does have it. I’ll find the source of the review when I can.

https://www.jonnyguru.com/blog/2015/05/11/enermax-digifanless-550-550w-power-supply/4/ According to Jon, this thing has OTP. https://www.tomshardware.com/reviews/enermax-digifanless-550w-power-supply,4125.html Aris says the same thing, it has OTP. I believe it even tripped while testing. The Digifanless is a solid unit. Nothing really wrong with it.

The go-to is generally the RMx. The RM is a downgraded RMx with excellent low-load efficiency, but due to this configuration, it whines like crazy.

PSU calculators aren't accurate and always overshoot. The "best" one is the calculator from PCPP. it's more reasonable, but still not entirely accurate. The only way to get accurate wattage is by checking the power consumption of the GPU and CPU. The rest can be a rough 20-40w estimation.

No, that's not how you should choose a power supply. Brand, wattage modularity and efficiency do not indicate quality. Seasonic: Has the trashy S12II, the Focus+ (Which has bad protections). Their Primes are good, but at their pricepoint, you could get a Corsair HX. Corsair: As great as Corsair has been doing recently, they do have one PSU that isn't good: The VS series. group regulated and a misconfigured OCP. Silverstone: No, just no. My research indicated that they fail a lot of performance and quality metrics. I'd avoid them entirely. As far as efficiency goes, it's not a quality indicator. Efficiency only means efficiency, not quality. And when it comes to efficiency, you're talking between 2-14% on average, which in the grand scheme of things doesn't mean much for money saving. There's a few good units that are 450w and are great. Corsair CX and bitfenix Formula Gold, for instance. You should choose a PSU based on: Is it within spec? Is the build quality good? Does it have a good design? What protections do they have, do they work and what are they set at? Does it have a good fan? After a PSU passes all those metrics, then you can start looking at: Modularity Efficiency Wattage In response to the thread, hello_there_123 suggested a good one. Corsair CX450 is a solid budget unit with a good design and fully protected. If you plan to upgrade, perhaps get the CX550 so you can have the connections necessary to upgrade the GPU.

My bad, my brain didn't register that they were 1000w+ PSUs. That's more or less normal for high end units. be quiet! doesn't really regulate the price IIRC. Blame Amazon. But my area of knowledge isn't how they price the units and such. Just the actual units themselves.

If you're in the US, be quiet!s stuff is going to be stupid expensive. You're better off looking to Corsair's HX series.

The M12 EVO is the same thing. Minimal changes were made, nothing substantial. It's still based on an ancient group regulated platform. Ripple and regulation were made slightly tighter, which was a useless thing to do since they're in spec anyway. At least on the 750w versions where it utilized DC-DC converters. The 620w version and below used group regulation, which almost never passes crossloads. Out of curiousity, why are you so insistent on defending an ancient platform? It lacks UVP on the 12v Rail, has no OCP, no OTP. This is on the sub 700w models. There's no reason to get one, and they're not suited for a modern system.

I think you're confusing it with the green label CXM from 2012. Yes, that unit did suck. But the new models from 2015 are a solid budget choice, than and the 2017 revision of the CX. If you're referring to the 2003 FSP, well, it would depend on the model in question, since he didn't state a model.

I'm afraid that isn't how it works. Seasonic never made any modifications to the platform since its release. The PSU is the same as it was nine years ago. Another thing to note, PSUs aren't software. They don't have bugs. They can have poor design choices, but not bugs.

The Focus has inherent protection issues which can be a concern. I don't recommend it for that reason. If you're talking about the 2019 RM, I'd rather get that. Everything is set properly on that unit.

Not how this works. PSUs don't get better with age. Specifications and requirements change. It has no place in a modern 2019 system. Lacks too many crucial protections and uses a topology that should've died back in the mid 2000s.

Hm strange. I could've absolutely sworn it was ACRF. Perhaps I've confused it with a Power Power 9. My bad. Well, if that's the case, then CX > SP9.

Yes, the System Power U9. I can find no information on a System Power 9 so I am going to assume they're the same thing.

650w is not needed most of the time, even more modern systems. You'll be fine with a 550w unit. Try looking at a Corsair CX or CXM, the ones with the grey label, not the green one. If you're in Europe or the UK, you can go for a be quiet! System Power 9.

System Power 9 is pretty solid overall. It has a weaker primary side (when comparing to the CX), actually. The System Power 9 has ACRF (active clamp reset forward) in a nutshell, it's just a more efficient double forward but may or may not present the same whining and possible transient issues that an average double forward design usually has. The CX uses Half-bridge LLC, which is the better overall topology. Better performing, more efficient, all around better. (Usually). Both units use DC-DC converters on the secondary side. Mt personal pick is the CX over the System Power 9, but if the CX is like, 30 or 40 dollars more then I'd just get a System Power 9. The CX is better than the System Power 9, but not that much better.

Focus + has some issues, but I doubt the 2060 Super will push the PSU in any circumstance for those issues to present itself. Yes, the 2060 super will be fine and you have more than enough wattage.

It's a bad PSU. Group regulated (Already bad) and OCP doesn't work right. Allows the 12v rail to drop to as low as 11v before being triggered, which is bad. Overall build quality isn't great, either. I definitely wouldn't pair it with a 2070 and 8700. Id' recommend you upgrade to a Corsair CX 550 or Bitfenix Formula Gold 550/650w (Ideally the forumula gold)

I still wouldn't. Group regulated PSUs are notoriously bad. You've already posted something similar to this several times and each time we tell you to replace the PSU when you can.

Ah right, keep forgetting that detail. Thanks

It could be a PSU issue. Bad voltage regulation can definitely cause crashes or freezes. I would try replacing it with a Corsair CX450. A solid PSU all around, if it is the PSU, then that’ll fix the problem.

If something was loose inside you’d have potentially big issues. coils can cause a high frequency whining sound known as coil whine. It’s normal and harmless in most cases.

Out of all those, the CXM. M12II is simply terrible. Group regulated, lacks protections, 10 years old, loud lacks C6/C7 sleep states Masterwatt bronze is... bottom of the barrel of acceptable. Worse than a CXM, but still acceptable as a budget unit for low wattage parts. Thermaltake is terrible for the same reason as the M12II is terrible. BQ isn't good for the simple fact that it lacks over temperature protection. (If a PSU lacks any protection, it's a no in my book.) But if I might offer a different suggestion: Bitfenix Formula Gold 550w. You can get it just under 80$ and it's far better than any of those PSUs listed above. https://www.newegg.com/p/N82E16817376010? It's actually 70$ https://www.bhphotovideo.com/c/product/1328664-REG/bitfenix_bp_wg550umag_7fm_whisper_550m_80_plus.html? 10$ more but it's fully modular.

That's weird. There are no moving parts in a PSU except for the fan. Rattling implies something is loose and vibrating within the PSU. Are you able to post a short video with the sound?

The EVGA 430w is a rather terrible unit. Definitely a good idea to replace it. The EVGA BQ is a no on my list for the simple fact is lacks over temperature protection. Here's a list of PSUs that I would personally get: Corsair RMx Corsair TXM Corsair CX (2017) Bitfenix Formula Gold Bitfenix Whisper M Formula gold is about 70$ and the best bang for your buck when it comes to quality and performance, but it's non-modular.
