PSU tier list 2.0

[MarkW]

I have read JG's reviews. I'm just saying, the Seasonic site shows that the M12II units have dual +12 volt rails in that chart that I posted. I know they do not. But if people go look, that is what they see.

The HX 650 is based on the Seasonic G platform. Excellent unit. And yes, more than sufficient for your build.

Thank you! And is buying a used (but good condition) PSU a good or bad idea?

I wouldn't buy a used power supply. Not unless it's from a friend or someone where you knew how it had been used and why they were selling it.

How about the Newegg Refurbished? (They have generally good reviews specifically for refurbished)

 

[Deleted member 217926]

If it comes with a warranty then that's probably fine.

Thank you.

Also, do you have any idea why I'm seeing that PSU listed as 80+ Gold in some places yet 80+ Bronze in others? It's all for the same PSU:

Gold
Bronze

The link you put up was Bronze, but when I navigated to the HX series main page on Corsair's website, that says gold...

Exactly, which is why I'm confused... I'm seeing it listed as both, all over. (And I don't know which one to believe lol! I honestly don't care whether it's one or the either though anyways, just curious)

 

[Deleted member 217926]

What you are seeing as Bronze certified was the old second generation ( 2009 ) HX. The first gen HX ( 2006 ) were only 80 Plus.

Okay.. so the HX650W i'd be getting refurbished from Newegg (if the price sticks, praying it does lol) is Bronze then?

Also, sorry for all my questions, but should I be worried by the reviews mentioning hearing a "chirping" noise from the PSU? (these are on both the refurbished and nonrefurbished version.) Does anyone here know of a fix for that (it seems to be from the fans speeding up/slowing down)

 

[Deleted member 217926]

Probably it's Gold. It says Gold in the title and the picture of the sticker on the side shows model number 75-001217 which matches with the newest Gold certified model. If they send you the old Bronze unit you could rightfully complain and at least get your money back. Read the user reviews. Seems to be hit and miss. Like it's fine electrically but the fan is stuck at 100%.

 

[MarkW]

There are actually 2 totally different pages on Corsair.com for HX650 power supplies... Talk about confusing!!

Professional Series™ HX650 — 80 PLUS® Bronze Certified Modular Power Supply

HX Series HX650 Power Supply — 650 Watt 80 PLUS® Gold Certified Modular PSU

My apologies if this post is misdirected, I'm looking for a solution to what I hope is a PSU problem:

Hello,
I recently built a PC with these specs:
CPU: i5 6600k
MOBO: MSI z170 Krait Gaming
GPU: MSI R9 390
HDD Samsung EVO 850 256gb SSD + 2 tb HDD
RAM: 16 gb g skill
PSU: EVGA NEX750B 750watt

The machine runs fine when it is functional. Intermittently, when pressing the case power button to power on the system, the machine does not power on at all. I have tried shorting the pins on the motherboard and using the reset switch instead to no avail. The problem mostly presents itself after extended inactivity (overnight, after coming home from work, etc.) The solution is solved when power cycling the PSU.

The problem also occasionally presents itself when trying to wake the computer from its low power standby state, but not every time. After this happens, power cycling the PSU and turning on the computer again with the case switch wakes the computer and resumes all my programs as normal.

I have temporarily bypassed these issues by powering off my PSU every night (should this be done)?

I have my computer plugged into a surge protector.

EDIT: After looking at the PSU tier list could it be that this PSU isnt suitable for Skylake or is just poorer quality? Should I consider returning it and replacing with a better PSU prophylactically? I am unsure if this is a Motherboard or PSU problem. There is a BIOS update for my motherboard but I am hesitant to flash as it seems like a risky proposition. I'm considering swapping out the PSU for an EVGA G2 model. I just hope this isnt a motherboard issue.

Any help is appreciated. Thanks.

The NEXB is not compatible with the lower power states from the newer CPUs, this is why your computer won't resume from sleep.

As for whether you should return the PSU? I would highly recommend that. For a latest gen computer such as that, I would definitely go with something tier 2, at least.

The EVGA Supernova B2-750W would be a great replacement. Or you could go for the G2 at 750W. A bit more expensive, but gold standard.

Does the low power state issue explain the computer not turning on after a period of being turned off (such as overnight)? I have intel C state settings turned off in my BIOS. I'm just hoping this is not a motherboard issue. Unplugging the psu and plugging it back in does the trick also. Any way to tell whether this is a mobo issue? A shame my board is so new so there doesn't exist much feedback online regarding its reliability. Also the computer only occasionally does not wake from sleep - mostly only after prolonged sleep time (+30-45 minutes).

 

[JaxAxRho]

That one I don't know about. I'll have to leave it to one of the more experienced members to answer.
I'm guessing most of your problems are originating from the power supply, so my recommendation is to replace it due to it's poor quality and see if the problems clear up as a side effect. My 2 cents though.

Does it only happen when the OS automatically places the system into sleep mode?

Does it ever happen on a manual shut down from the OS?

Unplugging the psu and plugging it back in does the trick also.

Indicates that a protection circuit has being triggered. Cycling the PSU's AC power switch is needed to reset the circuit.

Ko,
Thanks for the help.

It happens when I or the OS put it into sleep mode, after prolonged duration (I can usually wake it back up if its a relatively short period). It also happens with manual OS shutdowns, and I notice this issue most when turning it on after an overnight shutdown, or after work in the evening, etc. I'm not sure what the temporal threshold is to bring out the issue.

Do you suspect a PSU over a Motherboard issue? I know this unit is a "tier 4" unit. My CPU is also overclocked, if that makes a difference. I plan on replacing with a EVGA G2 model soon.

 

[Turb0Yoda]

Sounds like PSU. That OC might also factor in it. As always(unless your location bars these options), Seasonic, Silverstone, XFX, and the top end EVGA stuff.

 

[Benjiwenji]

If it's the PSU's compatibility issue with c7 sleep state, then disabling it should solve that problem. Assuming you didn't get a defective PSU, it is possible that the problem originated from elsewhere. Either way, you should look into a Haswell compatible PSU to take full advantage of your CPU, particularly if you're still within the refund period.

 

[stavrosmast]

Very Bad

 

[Karadjgne]

It's possible in some of the more advanced bios to set the low level of sleep, I have mine set to not drop below C4. I also think there is a setting in Windows under control panel/power/advanced settings that does the same thing. Setting those for 1-3 might solve the issue temporarily, if it does, then as said it's an incompatibility of your psu with the ultra low power states, and not necessarily a defective psu. Many older designed psus have such an incompatibility and as ko888 said, an under current or under voltage protection is kicking in and forcing a reset.

 

[Holycow98]

Ugghh...I can't decide which PSU....

Its time to get a PSU for my new build....

For the CPU I have bought a i7-4790k and a Asus Sabertooth Z97 Mark 2.
I haven't purchased the video card(s) yet. At a minimum I will run a single GTX 970 or R9 390. I may stretch the budget to a GTX 980. I have a BenQ XL2420Z that I want to try and get as many frames as I can (@ 1080p obviously) to take advantage of the refresh rate (144hz). I don't think I would crossfire 2 R9 390's but I've debated about SLIing 2 GTX 970's.

Anyway...the video cards will be the last thing I buy for this build...due to how it takes to save money.

I'm wanting to either go Seasonic or EVGA for power supply. Which of these would you go for if you were me?

EVGA 220-G2-0650-Y1 - http://www.newegg.com/Product/Product.aspx?Item=N82E16817438054
EVGA 220-G2-0750-XR - http://www.newegg.com/Product/Product.aspx?Item=9SIA24G28N0668
SeaSonic SSR-650RM - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151118
SeaSonic M12II 750 SS-750AM2 - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151107
SeaSonic X Series X650 Gold - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088

Feel free to suggest another...but nothing like a Corsair CX. Trying to keep the budget around $90-$110...but its not sit in stone. I'm ordering this Thursday so I need to make up my mind.

 

[Archaic59]

@ Holycow98 - The video card combinations you mentioned are all over the place requiring a PSU anywhere from 500 to 1100 watts. You need to decide the video card(s) before choosing a PSU.

 

[Holycow98]

My instincts are telling me to buy the strongest single card I could afford...most likely the GTX 980 in that case. However....this is my first time using a 144hz monitor....so I'm unsure of how much do I need GPU wise @ 1080p/144hz.

I really don't want to use sli/cf but I want to be able to at least get 100 fps to take advantage of the refresh rate. I mostly play shooters....with a splash of real time strategy. In shooters I don't mind turning the settings down in favor of higher frame rate.

I used this power supply calculator: http://outervision.com/power-supply-calculator and it seemed the only configuration of 2 cards I could run would be 2 GTX 970's. It gave its estimate of 560W under load and a recommendation of a 610W. As far as rails go it said 38.5 on the 12v rail. I would not attempt to crossfire a R9 390 without say a 1000 or so watt PSU and I can't afford to SLI 2 GTX 980's. In my case the GTX 970 would be the only SLI or CF option to consider.

 

[Holycow98]

I guess where I'm at is I either need a PSU for 2 GTX 970s or 1 GTX 980
