PSU tier list 2.0

[Archaic59]

You have an i7 cpu so you can use this as a guide. Add extra for overclocking-

Based off that it would seem I should go with a single GTX 980 or GTX 980ti (ouch to the wallet hehe). I was kind of leaning that way....either of those should be powerful enough. As a rule of thumb...I always like to add 100W to whatever sites like that suggest. So I need something between 620-700w. May as well just go with a 750W so...

EVGA 220-G2-0750-XR - http://www.newegg.com/Product/Product.aspx?Item=9SIA24G...
SeaSonic M12II 750 SS-750AM2 - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

or other suggestion?

Thanks so much for taking the time so far...its much appreciated.

The EVGA G2 series, made by Super Flower are among the best you can buy. That would be my pick.

 

[Karadjgne]

Sli gtx 970/980/980ti is 750w. Current best bang for the buck 750w psu is the Evga B2 750. For top performers look to the Seasonic X, Evga G2, Corsair HXi.

 

[MarkW]

Last time I counted, 14 of the 28 models in Tier 1 were made by Seasonic.

Anyways, I like calling Tier 5 power supplies the "Fireball Category". It seems to get peoples attention real quick.

 

[degreesofuncertainty]

i was wondering.. the new radeon r7 360 seems to draw only 100 to 110 watts (as per what i have read) other than torture testing.. however the recommended power supply requirement is 500watts.. would it run on a cooler master extreme power plus psu of 460watts? i am not considering the highly OC'ed versions of the graphic card either.. and no plans to over clock any thing else.. this psu has 2(x) 12v rails at 18A with over current protection at 19A.. so it should shut down if it cant handle the load..

on another thought.. would a tier 3 (gold or bronze rated) psu of 500-550 watts or be sufficient for a radeon r7 370??

 

[stavrosmast]

So I saw in a toms hardware guide not to gpu oc with less than tier 2 psu and my corsair VS650W is tier 4.. so that means that I shouldnt OC my 960??

So I emailed XFX to make sure this PSU would support my build:

Build: http://pcpartpicker.com/user/Feliks/saved/#view=fvKV3C

As a reply:
"It’s a little light on power, but technically it will work. Id recommend an 850W gold PSU as your PSU is the heart of your system and ultimately decides the longevity of your components"

An 850 Watt Gold? I'm not disagreeing with the last statement however that seems a BIT overkill. My build definitely does not use anywhere even close to 850 and I don't think going Bronze was a bad idea either.

 

[tiny voices]

They are idiots trying to upsell you. Emailing them is pointless.

Anyone here knows more about PSUs than whatever $12/Hr tech support idiot that answered your email does.

 

[Feliks]

Figures. That PSU is definitely enough for my build, then?

 

[tiny voices]

Yes it will be more than enough.

 

[stavrosmast]

but look the 290's min psu

 

[rmi05]

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.

A little update to my problem - the replacement G2 unit has not fixed the issue. The computer still does not start sometimes from a period of prolonged power-down. Could this be my motherboard? What could be the source of this issue? Will it worsen and eventually become a permanent issue?

 

[MarkW]

I think the only honest answer to that is "Ask the electrons flowing through your system."

 

[stavrosmast]

What about my question...

 

[tiny voices]

Yes, I would not overclock anything on a VS PSU from Corsair.

 

[rmi05]

I think the only honest answer to that is "Ask the electrons flowing through your system."

Any chance it could be a faulty surge protector? I did not see anything aberrant on my motherboard. Would a faulty motherboard cause these issues? The computer is completely fine when powered on, and does not turn off abnormally when functioning. Could an overclock somehow be related?

 

[tiny voices]

Could be crappy surge protector. Try plugging straight into the wall. Could be the motherboard as well. have you done a BIOS reset?

 

[MarkW]

TDP
250 Watts

I have seen stress tests take these cards over 300 watts. As long as your power supply is 550 watts or more, you should be fine. 600+ watts would be best.

 

[rmi05]

Could be crappy surge protector. Try plugging straight into the wall. Could be the motherboard as well. have you done a BIOS reset?

I'll try plugging into the wall tonight. What would be wrong with the motherboard? Why would a BIOS reset help? I could try updating the bios as there is an update available but I am a bit hesitant to update the BIOS...

 

[tiny voices]

Update the BIOS and then do a full BIOS reset. Sometimes things get set a certain way by mistake and then you have an issue. Sometimes a BIOS reset just fixes things inexplicably.

 

[MarkW]

Power supply.
Motherboard.
CPU.
Video card.
Intermittent short in wire(s).

Any of those could trigger a shutdown if there is a problem. These are very complex devices. And electronics are very sensitive to variances in power levels and other issues since that is in effect, their "blood". The order I listed the items above is the order in which I would suspect problem to be with.

 

[tiny voices]

I would probably rule out the CPU and GPU in this case. I'm guess it is motherboard/BIOS related.

 

[stavrosmast]

This is little bit off topic but is there another way to see if the gpu is burned except from when it smells?

 

[tiny voices]

Burned? Why would a GPU burn? What do you mean by burn?
