Can /g/ redpill me on the PSU brands ? Which one are reliable and which one we should avoid ?
>>54888732
Just get the cheapest one, it either serves you for 5+ years or not. Worst case scenario you'll just replace it with the same model, it would still be cheaper than getting those premium bronze gold+ boxes.
Read a bit up on http://www.jonnyguru.com/
You won't have a problem with Corsair, EVGA or Silverstone. Avoid unbranded and non 80+ models.
Reliable: almost all PSUs based on Seasonic and Superflower leadex platforms (Seasonic, most XFX PSUs, certain Corsair PSUs, EVGA G2/P2/T2 series, etc.)
Most PSUs from well-known brands are reliable enough as long as you have enough wattage to power your components. Before buying a PSU, check the reviews on Jonnyguru and make sure the PSU you're buying has enough amps on the 12v rail for your graphics card(s).
Avoid chinese garbage and lesser-known brands such as Diablo, Atrix, Aspire, Sharkoon, Wintech and so on. Thermaltake and Zalman for example are somewhat well-known, but they mostly have terrible PSUs so avoid them as well.
Pic related is a chart from leddit. It's mostly accurate.

As long as it's at least Bronze 80+ and not some chink brand you're fine
>>54888925
>Haswell compatible
What is this? Am I being fooled?
Powering a 65-140W CPU requires a special rating on the PSU now?

Buy the cheapest one from a decent brand.

>Worst case scenario it kills your motherboard or catches fire
>>54889267
I'll just point out that kys is associated with a strange youtuber and his strange fanbase, this strange youtuber even speaks as if puberty skipped him
>>54889247
It's just that Haswell and newer models have some weird sleep states that need some PSU compatibility
>>54889247
Haswell's sleep power draw is substantially lower than that of previous generations, and it can trigger some PSUs' under-voltage protection and force a system reset.
Google it m8
>>54888839
Corsair CX series for overclocked/high wattage builds probably isn't your best bet though. For mid-low level gaming builds they're ok.
>>54889247
haswell has a C6/C7 idle power state that draws an ultra low current from the PSU.
some old cheap PSU don't support it, but you can disable it in bios
10-15 dollar Chink unknown brand psu that came along free with most cases will do just fine.
it will die around after 4years
im already in my second one. no damage in mobo or anything
>>54888732
There is no reliable PSU brand. Everyone makes a dud. Refer to JohnnyGuru and go by model #.
Is this okay PSU? Its 30 euros.
>>54891007
> 30 euros
you dont even have to bother looking at specs or the brand at that price point.
It's garbage and unless you want a housefire, I would avoid.
overload protection
anything else is surplus
buy new too, they all come with 12 months warrante
If it lives for 12 months, it'll live for 5
I bought a chink 600w that died within 6 months
they sent me a 750w replacement and it's still going
>>54891030
The thing is i already have a lower watt psu of the same brand and its lasting me now 6 years or so.
>>54891050
Okay? You're also probably barely putting any load on it.
Try hooking up a 140w CPU and a 300W GPU to that and run a stress test.
$20 says it will shutdown.
God forbid you want to overclock.
>>54891007
its okay
but anything above 500w-600w is useless unless you sli/cf
gtx titan x could run on 450w
>>54891073
Im on a real tight budget so i have to consider low quality parts.
>>54891099
Well what are you getting? a more expensive unit from a better brand with a lower wattage rating is probably better than that piece of garbage with a 600w rating.
Unless you're building an SLI rig, you can probably get by with a quality 400-500w unit from a better brand.
>>54891130
An intel i5 4690 (not gonna overclock) and probably an AMD graphics card later on.
>>54891169
>i5-4690 84w TDP
>RX 480 150w TDP
So that's ~240w from the GPU and CPU. Add another ~60-120w depending no the hard drives, RAM, ODD, etc.
At MOST you're looking at 400w power draw. And that would be in the most extreme stress test you can manage. During normal use and gaming you'll be hard pressed to go over ~250w.
A quality 400-500w PSU would be MUCH better.
Look for something with a SINGLE 12V rail rated for at least 30A.
>>54891233
Alright mate, thanks for the help!
Anyone have a fanless PSU? What's the catch?
>>54892216
The catch is they can't go over ~520w right now without overheating. So if you have a normal computer with a single GPU you can go for a fanless PSU comfortably, but overclockers and people with SLI will want to stick with a solid 700w+ unit, some of which have fanless operation at the low end anyway for when you're idling and not drawing as much power.
How are the Nox Hummer PSUs? I never see them mentioned or in any chart. I have one, specifically a 750w Modular Bronze 80+, had it for over a year now with an R9 390 and never had problems with it, but never seeing the brand named anywhere is weird. Anyone know anything about them I should know?
>>54888732
I like EVGA
I've had two corsair 750w psus in two separate PCs and both ended up dying on me within 2 years of purchase.
Three of the PCs I've built have had EVGA psus, one of them is now 5 years old and still kickin.
This time around I got myself a 600B for my ultra budget build
>>54892271
Hmm, unfortunate.
>>54888732

Shut off once when I was increasing the gpu power draw on my OC profile in afterburner but I put it back to 100% and it runs fine on full load

avoid iMicro like it was dripping with ebolaids and will rape your whole family.
>>54893576
You would have to be retarded to get a single rail psu for a gaming PC.

>If the user is unlucky enough and happens to be acting as grounding at that exact moment, this could be even life-threatening. Are you sure you want to risk your safety installing an unsafe power supply like this?
What a lovely, entirely inaccurate statement.
Is this good?
>>54893941
Yes, that is more than good enough for any single GPU and single CPU (except maybe the FX 9350 220w bastard) with a decent number of hard drives.
>>54893941
>Single-rail
No, it isn't.
>>54893959
Alright, cheers!

Mind explaining me this rail stuff?

Think of it as circuit breakers. All power supplies have one giant 12 V supply in them, but "multi-rail" supplies divide it up over several smaller circuit breakers, like your house. This means that it's less likely to cause your wiring to catch fire if you draw too much current through a single wire (for instance, if you use MOLEX to PCI-E adapters).
>>54893993
When you're talking about well known higher end PSUs, having mutliple rails isn't an issue because they have proper OCP and good quality rails are assured. However, in the low price point bracket multiple rails tends to be a sign of cheap design and trying to save money. A cheap 450w PSU might have 2 15A 12v Rails for 360w of power. Whereas a good 450w would probably have a single 34 or 35 amp 12v rail providing slightly over 400w.
Again, for higher end units it's not really a concern, but at the sub $50 range. Try to get a good powerful single rail over multiple rails.

i purchase a S12II blindly cause "muh sesonic can do no wrong :^)"
not even 1 calander year its went to shit and already got RMA
replaced it with a not-even bronze certified EVGA 400w PSU that stabilized the system
and upon further review found out that hardwaresecrets took apart the S12II series and found out the caps arent japanese and arent solid
>>54894970
That's why you always look up a good review on a unit before buying, even if its from a well known respected company.
>>54888732
PSU brands are just a gayming meme.
Just buy a Diablotech
>>54888732
been using diablotek for 20 years, never had a problem.
>>54894970

The country of origin says nothing of the quality.

Are you fucking stupid?
>>54888732
>redpill me on the PSU brands
you mean like: half of them are made by the same company and they are all made by the jews. thats why the psus that come in cases always burn out, so you have to buy new ones.
nigger what the fuck do you mean red pill you on psu brands? buy one with at least the rating you immediately need, and don't buy the cheapest one you can find.
>>54895051
>PSU's that come in cases
what do you mean?
that its better to buy the silver ones that dont even come with a power cable?
>>54895103
computer cases, like the tower shell.

Only $19.9 and it has four LEDs. Has been supporting my gaming rig since my old $7 PSU burned when dad was welding. I just replaced a fuse that costed less than a buck and sold the old PSU to a friend for $3; PSUs are piss easy to fix and fancy PSUs are the jewest scam. Come at me haters.
>>54895163
oh i thought you mean packaged
literally everyone knows case PSUs are shit
that being said, a ton of ppl with lion psu's in their prebuilts are still running fine

>>54895349
yea, mines a prebuilt from 2008.. probably 2006 I dont fucking remember. My psu is a liteon, damn good company. They make good disc drives too.
Do power supplies use less power then they are rated for if your components don't need the power?
Like if you have 800w PSU but your components only need a total of 400w, is the PSU always drawing 800 or just 400?
>>54895381
Ill speak english for our foreigner folks. After reading this thread a bit i chose >>54893941
. Unless someone proves me its shit ill stick to it. Pic related is the psu.
>>54895427
Depends on the efficiency rating of the PSU. if your PSU is rated to give 90% efficiency at 50% load then in your scenario of 400w draw on an 800w PSU it will actually be drawing 440w from the wall (10% of 400 is 40, 400+40=440)
how is bequiet! doing? I bought one years ago and it's running well.
>>54895427
no, you want the PSU to be working at just below 50% for maximum efficiency
because of the curve
unless you pay $1000 for a platinum rated supply
and unless you're building a gaming rig, the estimated wattage listed on pcpartpicker is the max usage, you'll never be near that, so you could get a PSU just at that capacity
just make sure you use a percentage calculator and find the lowest total number where 80% is still more than what you're PC would use under full load, and then set that on pcpartpicker and search from there
>>54895648
>unless you pay $1000 for a platinum rated supply
I have a 80+ titanium rated power supply, cost me $140.
>>54895609
wait a sec
>>54895669
>$140
thats what i meant
and i bet its fucking only 300wats or some shit
not the 1000Watt antec
>>54895685
>300wats
It's 600 watts and they offer a 700w or 800w Titanium rated for similar price.
I have a single GPU though and dont plan on going crossfire or SLI so I have no need for more than 600w.
80+ titanium specification requires at least 90% efficiency at 10% load levels and at least 94% efficient at 50% load levels.
So considering my computer gaming pulls ~280-350w it is MOST efficient for me when gaming, but even at idles levels, it's still 90% efficient.
my 6 year old ultra lsp650 recently blew up on me, shit starting smoking and a nasty burning plastic smell filled the room. Got myself a good deal on an evga 600b (80+ bronze) to replace the fucking thing.
