nothing to do with it

 

a single rail is just fine when it works

 

but when it doesn't, one or two protections miss it and you have the full amps through the one malfunctoining device in your system

 

that's why we generally say above 650 a multirail

Ah, so it's not to say one is more reliable than the other, but in the event of a failure, the single rail has a better chance of frying a part?

pretty much

 

the undervoltage protection could stop it, but someof them don't work well, so i'd recommend multi rails

 

there's no downside to a proper multirail i'm aware of

That makes sense, thanks.

Sorry for the double post, but I noticed some PSUs now, like the corsair vengeance, are switchable between single/multi rail.  Know what's up with that/why that would be beneficial?

If someone uses it for a purpose that actually requires more from a rail that what the OCP allows, it can be switched to single rail mode. It's also there for the ret@$&s that think that single rail is better.

It basically becomes a welder instead of shutting off sooner in the event of a short. ;)

Hmm, so how do you guys feel about the vengeance overall (550/650)?  Compared to say the CX?  Is it a different platform altogether than the CX or TX?  Would it be good for a low powered system 24/7 operation?

Are we talking about the old Vengeance or the new Vengeance?

 

The old Vengeance is the same as CX-M, but with all Japanese caps.  The new one is a much upgraded platform.  LLC instead of DF.  Also has zero-RPM mode and the +12V rail single/multiple switch.

 

Since you mentioned the switch before, I'm guessing you're asking about the newer version.

All this chatter about multi vs single rail, I just realized I had chosen the RMx850 (a single rail unit) for an upcoming dual Xeon/dual GPU build I'm working on. I'm sure it would have been fine, but my OCD has prompted me to swap that out for the Bitfenix Whisper M 850. ;)

At one point I was considering the RMx White but I read it has cable capacitors.  Sounds gross.

The white one comes in two versions.

 

The newest one has no cable caps.  They're just regular PSU cables, but in white with white sleeves.

The old one with individually sleeved cables has caps, but they're in the middle of the cable and easy to hide.

A friend of mine is using a Corsair TX650, which he got back when Haswell was new. What kind of lifespan should we expect? It used to power a 4770k and 760, now it's got a 1050 ti.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

About 5-7 years, so now would be a good time to upgrade.

The more "noise" filtering, the better, IMO. ;) 

 

The whisper M has in-cable caps, but they hide them in a boot on the 24-pin connector.

Price depends on region, 550w MWE gold is 70 euros where I live and 550w Focus+ Gold is 105 euros, that's 50% more

friend swapped out G3 750 with MWE 550 Gold(full modular) and he is super happy, it's silent even when stressing OC'd Ryzen 7

Even at that price there would be many better options in most countries. And that swap is a downgrade.

Well it has not been tested anywhere to the same extent as G3. It could be a lot worse on those minor issues g3 has. I would not dare to recommend mystery psu:s if at the same time I made nitpicking complaints on others.

I've seen things from cooler master... they let people like the mask test there once in a while

 

and unlike the g3, it hasn't shown any protection issues so far

That's not true for the EVGA models. They do have OTP:

a lot of them don't...

I don't think they have OTP.

 

EVGA G2:

https://www.techpowerup.com/review/evga-supernova-g2-650/2.html

Quote

The unit doesn't feature Over Temperature Protection (OTP), which is unusual for a Leadex platform.

 

EVGA P2:

https://www.tomshardware.co.uk/evga-supernova-750-p2-platinum-psu,review-33575.html

Quote

The list of protection features is notably missing OCP for the +12V rail, since this is a single +12V rail PSU, and over-temperature protection.

That's odd. Tom's states otherwise:

 

"We should note that the newer G2 units also featured OTP, although EVGA didn’t mention it in the specifications." 

 

source: https://www.tomshardware.com/news/evga-supernova-g3-psu-fan,32995.html

 

So I think TechPowerUp JUST went off the spec sheet and didn't dig any further. 

 

An ex-reviewer at Jonnyguru also states that all G-series units feature OTP.

 

source: http://www.jonnyguru.com/forums/showthread.php?13101-EVGA-Supernova-G2-P2-and-the-lack-of-OTP

 

I also asked EVGA directly back when I was buying the unit and their response to me was (this is a snippet): "Rest assured that all of our SuperNova power supplies feature all modern protections including over temperature protection."

 

So it seems there's quite a bit of misinformation out there

 

I don't see any further information about P2, but I think it's probably the same situation.
