HELP: Power Required For The Following Setup?

[Shadowman007]

How much power is required for the setup below? and also if anyone can recommend a really good power supply. Thanks.

MOTHERBOARD: Maximus V Extreme Z77
CPU: i7 3770K Overclocked to 4.6Ghz to 4.8Ghz
CPU COOLER: H100i In push/pull with 4x Gentle Typhoon AP15 fans at full speed
GPU: 2x Nvidia Titan in Sli Maybe a mild overclock
MEMORY: G.Skill 2400Mhz DDR3 32GB ram
SSD: 2x OCZ Vector 256GB in raid 0
HDD: Western Digital Caviar Black 1TB SATA 6Gb/s (WD1002FAEX)
DRIVE: Blu Ray Dvd/Cd Reader/Writer
CASE LEDS: NZXT White LED Sleeve - 2m

An AX860i would most likely fine but you may want to go with something more powerful like an AX1200i just to be safe

Well, lets see:

MOTHERBOARD: ~ 6.2 W for the chipset, according to specs, so let's assume 20 W to be safe.
CPU: Let's say about 160 W (77 W on stock if I recall correctly), since this is different for each CPU we'll allow some headroom.
GPU: 2 x ~ 250 W, so lets go with 550 W
Rest: Negligible, let's take 30 W.

Makes in total around 760 W. The one thing I'm a bit uncertain on is the CPU wattage, so if I'm too low on that someone should correct me. I think it's on the high end though .

Recommended PSUs:

• Corsair AX860i
• Corsair AX1200i if you want more headroom for future expansions
• Seasonic P860, P1000, X1250

If it was my personal system I'd probably go with the Seasonic P1000 or the AX860i unless I was sure I was going to add more GPUs later on.

Just would like to thank both of you for the replies really appreciate it.
I was also thinking maybe something like 1000W should be good gives me some headroom but then again I probably won't add/change anything to this setup and will run it for a couple of years 5 to 6 maybe. That is if am still alive

Yeah a 1 kW unit would still give you enough room to add one more Titan, more or less (assuming my power estimates are a bit generous and you don't really need 760 W), but at that point it would be running at 100%.

But if you're confident you won't make changes that will require more power I think a 1 kW unit will be perfectly fine, or even an 860 W one. As said, my choice would probably be the P1000.

However, 1200 W would not be complete overkill, it's still perfectly justifiable depending on future plans, just not necessary for the setup you described.

there are some reviews with sli titans and a six core i7 and in games uses under 650W.but yeah when the cpu will be fully loaded it may be at 700-750W.seasonic 1000W would be fine

no more than the AX860i for 100% loaded use.
