The Gigabyte Z87/Haswell Overclocking(OC) Guide - Page 268

Guys i got a very silly and of to[pic question but you guys know much so i thought to ask biggrin.gif
I am gonna buy GB GTX 760OC 2gb GPU but my PSU is kinda week 430W and i got money only for the GPU atm. So would it be a problem for the GPU with this PSU in the specs of the GPU says that it 500W system PSU the GPU it self uses 170W i think saw it in Nvidia page.
So aither i can buy the PSU first or the GPU can buy both atm would i mess up the GPU with the low power PSU?

A 4670k at 1.3vcore plus a 760 @1.212v (max volts you can set unless you're doing crazy enthusiast things that you 99% probably won't be doing if you have to ask these questions) ~

You wouldn't have any troubles with power draw. It's way short of being a problem for a quality 430w unit, it's pretty much exactly where you want it for efficiency reasons.

If you have a quality 430w unit or a trash one is another matter. GPU pages have to take into account terrible PSU's because most people don't know anything about power supplies.

Yep pretty trashy, you should probably get a new one before running 4670k+760

400-450w isn't a problem, but a psu that can deliver only 29 amps of 12v (348w) split up 180w on one rail, 168w on the other - that isn't 80+ rated and probably fails with a bunch of stuff like ripple and voltage regulation is literally just playing with fire. You'd be highly loading it and it might not hold up well, stuff like damage to components is also probably a possibility (i'm no expert)

Use fixed Voltage.


Okay, so you cannot turn it off in a gigabyte Z87?

Unless you disable EIST and c-states, many boards including giga behave like..

Adaptive volts/frequency - UP TO the frequency and voltage that you set, but not higher. My CPU when web browsing, playing vids etc is bouncing around like 800mhz-2ghz for example

Meanwhile, the integrated voltage regulator targets ~0.02v higher than you set in bios, but if you set 1.35 bios you'll never see more than ~1.37 from multimeter, with very slight variance (because ivr is pretty good at what it does, way better than say z77 mobo voltage regulation by design)
