im looking for a 750-850W power supply that wont blow up as soon as its under load with my build +dual gtx 760s
post #2 of 15

Dual 760s in your system would not need anything 'bigger' than a good quality-made 550W-650W PSU because your power consumption while gaming will only peak at roughly 500W.

 

What store(s) can you order from and what's your budget?

The 500W minimum is for 500W peak-rated PSUs. The typical 500W peak-rated PSU would have a +12V capacity of 360W which is 30A. That's the typical +12V capacity of a decent 400W PSU, or of the 360W SeaSonic G Series (yeah, a 360W PSU with a +12V capacity of 360W - not bad). Like I said, your power consumption while gaming will not exceed about 500W with two 760s in SLI in your rig. A good 550-650W PSU is more than enough. Most people just don't know what they're talking about when it comes to PSUs because to most people, PSUs are boring. To me, they're the best part of a computer. lol

 

You have a great budget here because look at this PSU that you can get:

 

The 650W Rosewill TACHYON Series for $139.99 with free shipping available

 

This happens to be a very high-end PSU. Look no further, I'd say.

Dude. :)

 

http://www.guru3d.com/articles_pages/geforce_gtx_760_sli_review,4.html

 

With two GTX 760s in SLI, their PSU pulled 449W from the wall outlet. Their CPU was idling, so if I add 150W for your CPU (overclocked), then that makes the PSU pulling 599W from the wall outlet. Let's round that up to 600W. This means that if your PSU is 90% efficient while pulling 600W from the wall, then your computer is pulling 540W from the PSU. However, your gaming power consumption would be even lower, topping out at roughly 500W. Or, maybe it might start stretching close to 525W for some games... maybe.

 

So, let's just keep it simple and say that a good 650W PSU is more than enough and you'll have nothing to worry about. Don't worry yourself sick over these little details that don't matter. ;)

Stop doubting me. :) lol Again, that's for peak-rated PSUs. The typical 700W peak-rated PSU would have a +12V capacity of 504W which is the same +12V capacity of some semi-decent 550W PSUs. If you were to get a GOOD 550W PSU, then you'd have a +12V capacity of 540W. Or, if you got a good 650W PSU like that Tachyon, then 648W. So you can see how even a good quality-made 550W PSU would be enough.

Hardware use a blot less power then you think, a 650 watts can power almost any system even with two video cards its only if you start overvolting your video cards that you need more power

A stock gtx 760 use a little more power than a 660ti.





A seasonice 620 watt was enough for my two 660ti at stock settings. Zero issues except the psu fan would get a bit busy but no big deal it wasnt very loud.

When I overvolted my 660tis via bios mod The Driver would crash like crazy at only 1206mhz. With my seasonic G750 I am able to clock my gpu up until they artifact (1346mhz) without driver crash or pC shutdown.

This was my experience YMMV thumb.gif
