Seasonic x750 enough?

post #1 of 12
Thread Starter 
Basically looking for reassurance that I didn’t get to low of a PSU or if I did, I’d need to get the x850 (or whatever I find on sale). I did research quite a bit, but have read several confusing threads lately. In general from what I’ve read its suggested that a quality 750w would handle SLI 570’s. Now does that include if the CPU and GPU are OC’d as well? Not planning on going extreme but some OCing

Between what I read on the Guru site and a few threads I’m getting confused again.

Though while I wasn’t planning to do any Physx card, would I be able to if I wanted to check it out?

Currently already have everything below, just waiting on restock of Motherboard and Graphics card. My build when fully complete will be…

CPU: I7 2600k
Motherboard: Asus P8P67 Deluxe
Ram: G.Skill Ripjaws X Series 8g (2x4)
GPU: Evga SC GTX SLI 570’s (1 now, other when I get new monitor)
SSD: perhaps 1 down the road
HDD: Spinpoint F3 1TB x2
CPU Cooler: Noctua NH-D14
Sound Card: On board (I do have a PCI SB Audigy ZS Gamer)
Card Reader: Generic
Optical Drive: Lite-On 24x DVD
PSU: Seasonic x750
Case: Azza Hurrican 2000: 8 fans: 4 – 230’s, 4 – 120’s, with room for 1 more 120/140 at the bottom

Got the x750 on sale, but sorta forgot my case has 8 fans

Hoping/guessing I’m still good, and will not be pushing the PSU near limits?

I’d like to assemle it correctly right off the bat and nip this in the bud now and avoid issues later

thxs

earlier today i had also did one of the online power calculators, Antex i believe it was, it put me over 750 (close to 800w.

gonna see what the linked one above yields.

read a few posts stating that the online calc. are not reliable, are they really bad or give ballpark figures?

Ballpark figures only. Always give yourself 50 watts Padding at least that's my opinion.

My system recommended 498W

I bought the HX 750.

I like head room in case I want to ever upgrade my SLi 460s

Besides most of the calculators are generating calculations at 90% Load.

How often are you at 90% load for extended periods other than when running tests?

You can't trust those online calculators.
The good thing about them is that if you listen to them, you'll never buy a PSU that's too weak for your needs. On the flipside, you'll be wasting money on power you don't need. So if after you run your specs through the calculator, it gives you a figure higher than 750W, ignore it, plug your system in, and I guarantee it will work fine.

You'll have plenty of head room. That system will pull less than 600w.
Finally an update
