Hello,

I recently purchased a pc with the following build and am worried about its power consumption:

Case: Corsair 450d case
Processor: Intel Core i7 4770K 3.50 GHz (Unlocked CPU) (Quad Core). Overclocked to 4.5gHz
Motherboard: ASUS MAXIMUS VI EXTREME
System Memory: 16GB DDR3 1866MHz Corsair Dominator Platinum DHX
Power Supply: 750W EVGA SuperNOVA Gold Rated (Dual SLI Compatible)
Optical Drive: DVD-R/RW/CD-R/RW (DVD Writer 24x / CD-Writer 48x)
Storage Set 1: 1x SSD (250GB Samsung 840 EVO)
Storage Set 2: 1x Storage (1TB Seagate)
Graphics Cards: 2x SLI Dual (NVIDIA GeForce GTX 780 3GB (EVGA Superclocked ACX Cooler Edition)
Sound Card: Creative Sound Blaster Z
Cooling: Corsair H100i 240mm Radiator Liquid CPU Cooler (Extreme-Performance Edition)

Will the 750w psu be enough for this build or will I have alot of issues when I receive the computer?

Thanks for the help!:)

Yeah, like I said, you'll be fine running it on a 750w. If you can upgrade to an 850w unit, great, but if not, I wouldn't worry about it. As long as you're not going to be running the system 24/7, you'll be fine.

EVGA warranty's that power supply for 10 years, and has great customer service should anything actually happen. Sleep easy :)

That is pushing it, I'd say you need a bigger PSU. This might be a little costly, and overkill, but I'd recommend picking up this Corsair RM1000 psu:

I was looking at it, and that is right at 700 watts. But with it pushing out a 4.5 ghz i5, 2 750's and some extreme gaming, your going to need a bigger pc at that. I would cancel this order honestly. There is alot of waste, and it could be better, here is my recommendation:

My thing is, 2 780's are extreme overkill, and are not needed. For a few bucks below 2k, you can get a machine like this, with some nice parts that will push out gaming on Ultra settings at over 100 fps. Edit- also, really you spent over 350 bucks for a motherboard? Let me give you a lesson: The most expensive isn't always the best. The only time I'm going to drop 250+ for a motherboard is going to be on an LGA 2011 mobo, which is the hexacore one. For this, one at around 150 bucks will handle it. If you insist on one that'll do quad sli, then there is a Gigabyte one for 206 bucks that'll do it. Also, it's not even z97. If I was going to spend that much, then it'd have to be, and I'd be on crack.. No offense to you man.

I never said you were making fun of his build or anything, just explaining that 750w is enough for 2 780s, and that the RM series is an awful model for high end builds.

I definitely agree your build is much more price/performance efficient, though (minus the PSU) and would recommend that kind of route over what he has selected.

I build together the build he had, and it was about 2400 bucks.. I mean if you want quad sli and stuff, then it's around 2k, but eh whatever I suppose :p

Thanks for the help guys. I really appreciate Diox55 that you put together all those components, and I totally would cancel my order and buy those if I had any hope of being able to build a PC by myself, and i definitely do not haha. Plus I have a rather big budget, so the comfort of a boutique putting together the system is worth the over-priced build imo. So I am going stuck with this build.

At least I know now my computer won't crash the second I try and game as it can run a 750w psu haha. I am gunna try and see if I can upgrade it before it is to late however.

I wish I would've saved that build hmm, I'll remake it. When I first looked at that (yes this is legit), it started out as a quad titan build, lol'd.

A guy supposedly wanted to build this. He told me he was going to overclock the hexacore i7 to 5 ghz, OC the Titans, and keep it for 10-12 years. I was actually approached by a man on here after this wanting a full server and extreme workstation build, and this came out of it (I don't know how):

This is a build that actually happened, and no he didn't shell out 9k. This was for an office and they gave him a huge frickin budget. I don't why an office like his (it was around less than 100 employees) needed 40 TB of storage, quad titans, 64 gigs of ram, and a hexacore i7, but oh well. Go insane for all I care >.>..
