PSU tier list 2.0

[turkey3_scratch]

I wouldn't use either unit in any system requiring supplemental power.

Agree, but most systems these are used in are usually ~250W systems. In order to have a 500W system, you need an R9 390X. And then gaming load is usually even lower.

Okay.

not sure if troll.... http://www.tomshardware.co.uk/answers/id-3052916/good-psu.html

 

[turkey3_scratch]

Seems trollish or super misinformed to me.

 

[Deleted member 217926]

Possibly confused.

 

[turkey3_scratch]

So listen, I flipped the switch (probably should have held pwr button like I usually do) to my PSU because for some reason my computer did not post and was just a "no signal screen", and when I flipped it back on, I heard a horrid grinding noise from my HDD. My PSU is EVGA 850 G2.

Do you think possibly this could have been a situation where the AC loss and PWR OK signal cutting in too late and low voltage caused a potential problem?

The hard drives all work perfectly fine. It was just weird.

On the second hand, I need to figure out why my PC won't post unless I flip the switch of my PSU and flip it back on.

See, even the best PSUs can explode http://www.jonnyguru.com/forums/showthread.php?t=13277

In this case Aris thinks the RM650i blew up because the thermistor did not have a relay with it, as he says a relay does not only boost efficiency but allows the thermistor to cool down, too.

hey guys, just checking that the silverstone SFX SX500-LG is included on the tier 2-silverstone list? (as in, I can see that silverstone LG series is there, but im confirming that this PSU IS a silverstone LG)

 

[Darkbreeze]

THAT, is an interesting thread.

 

[turkey3_scratch]

THAT, is an interesting thread.

I know, and I also now know that there is more importance to a relay than just efficiency.

 

[Karadjgne]

Interesting yes, but slightly beyond by scope of comprehension. The RM series was plagued by bad thermal properties to begin with, which were supposed to be fixed in the newer models. So is that thermistor and relay or lack thereof, just one of the things that should have been looked at also? Or just a leftover from the previous design. While the build is quality and the performance top notch, the RMi is too new to guage longetivity. So is this a one off death chalked up to 'it happens occasionally' or something that needs watching like the CX average lifespan?

 

[turkey3_scratch]

I almost find it hard to believe the thermistor exploded in it, though, because although it can get hot, if a thermistor is going to explode, one would think that would happen during the turn-on phase I would think when there is inrush current?

I'll be interested to see the outcome of what exactly has exploded.

 

[Karadjgne]

It's electronics. Anything can fail at any given time. Even if there was a relay circuit of some sort, if the relay doesn't get engaged after the initial inrush then the full power of the psu will get stuck running through the thermistor instead, which it's probably not designed for since no psu runs at anything close to full load power during startup phase.

I'm sorry if I missed it, but is the Corsair CX450M good? 5 years warranty.

http://www.corsair.com/en/cx-series-cx450m-450-watt-80-plus-bronze-certified-modular-atx-psu-eu

That's the newly revised Corsair CX450M, CX550M, and CX650M with 100% Japanese caps and some other minor improvements. DC-DC regulation for the 5V and 3.3V rails.

 

[RCFProd]

Hell yeah! The CX450M might be going into my next build. Cheapest in my country.

This makes 750W Cooler Master V750 (RS750-AMAAG1-EU) a tier one psu then, yes?

Yes, since it is in the Tier 1 section 😛

 

[turkey3_scratch]

Seasonic S12ii prices seem to keep shooting up, out of my recommendation range.

 

[okcnaline]

$60 puts it off the XFX, Antec. Even the 80+ SeaSonic garb.

EVGA GQ 650: What's up with these units. I don't personally own, but there is a slew of NewEgg customer reviews stating units coming DOA.

There are some things to take into account though:

1) People may be coming from a turd PSU that damaged their components like the motherboard, only to think the PSU is DOA when it's really not.
2) Building errors, you never know what mistakes people make and immediately go to blame the PSU. These people who say it won't "power on" - who knows what they mean. It could be a motherboard issue if it's a new rig. I haven't seen any of them update saying the replacement fixed the problem except one guy.

Of the three DOA units in the reviews, 2 may be user error. But they also reviews within the period of, like, a week, so it could be something went on at the FSP factory. Worker gone mad?

What do you guys think of the DEEPCOOL DQ550ST http://www.hardocp.com/article/2016/03/24/deepcool_dq550st_550w_power_supply_review/1#.VzEx8PkrL1s

Pretty good unit performance-wise. If only they didn't use Elite capacitors it would be so much better. It runs for about $60. It's a shame they couldn't use some better caps, these would make great purchases. I mean, if you're not someone who believes in the whole bad caps tahoo, it's actually quite good for the money.

 

[Karadjgne]

When faced against the Evga B2 750 for $50, its not really all that good of a deal imho

 

[logainofhades]

I read newegg reviews, as a source of entertainment. So much fail in there. Like the one I read awhile back saying a monitor wasn't Windows 10 compatible. :lol:
