I'm using a Silverstone 1000 watt, 86 rating (I think) PSU that I gutted from my old Falcon Mach V purchased back in 09.  I can OC my card to stable 2050 but above that, my driver crashes.  Is it possible my psu is holding it back?
 
Specs (off top of my head):
Asus Rampage V mobo
16gb gskill ddr4 ram
5930k cpu
 
Thanks for any advise!

As Sajin said, nope.

These cards OC like bandits by themselves. Most folks that manually OC can get a bit more, but that usually means getting to 1900 on the low end and 2100 on the high end (purely silicon lottery there - extra power connectors and power phases don't actually help more). The only way to OC higher is exotic cooling, such as LN2. Water cooling does nothing but keep the OC from thermal throttling down if your fans can't keep up.

Tx for the replies. Saved me some money. One of my friends is convinced that I can use a better PSU but I suppose I will hold off on that.

Your PSU is more then needed and i mean a lot more. some guys OC this card with 550W-600W psu's and they have no trouble what so ever. 
by your friends statement i am assuming he is pushing you to upgrade the PSU to a nuclear reactor with uranium :D
1000W is alot already :)

Have you been using the unit since 09? If yes, you should really look into replacing it.

My brother is using psu corsair Hx620w with gtx 1080. That psu is from the year 2006 and he clocked to 2100 on the core... Good psu last for decades. I am sure yours fine as well.

Using a old psu with new hardware isn't very smart. The ripple on the psu could be out of whack which could cause hardware damage.

everything is working at stable voltages and with no problem what so ever ... damage from what :)...
a 12V rail with lets say (for example) 38A is the same as new psu with 12v rail with 38A... all the added things like bronze,silver,gold,platinum ... is efficiency. his psu is a legend lol .has stable voltage and amps on all rails. (stable like a rock for years)
 
after saying that i start to wonder ... the life expectancy of his GPU (and mine ) is 10-11 years (AKA 100,000 hours)
i think maybe it's time to buy a new one after all. :(

Read about voltage ripple hear... http://www.gamersnexus.ne...e-ripple-and-relevance

well my gosh, that's very informative. thanks for the link and info... i wonder now :S what program can i use to log\monitor this ripples :S?

You'll need an oscilloscope.

This will be a bit of a shock but ... i am not an electricity engineer hehe XD
have no idea how to use Oscilloscope :(.
i thought i can monitor that via Software like aida 64 (it shows the voltages through MB sensors)
but i guess it's not accurate -_-
Oh well ... time to upgrade PSU :P
Think i'll grab 750w Supernova G2 price is going nice atm.
or a seasonic M12 II 750w\650w
 
for my bro that is... i wonder should i change mine hx650W as well or it's fine ?

I don't really think there any advantage to extra phases or power plug, if there was i'm pretty sure nvidia would have released it with another power plug.
Having an extra bios chip however is sweet especially if you like to flash bios for overclock, but then again you probably only do this once.
Kinda wonder if we ever gonna see cards push way beyond 2,2 ghz so far most cards hit tops 2,1 2,152, think overclocks right now are mainly limited by driver / oc software.

You can get >2.2GHz with LN2, but I have yet to see any fully stable 2.2GHz OCs on 1080s under air or water. Several 2150s, quite a few 2100s, many 2050s, but no truly 24/7 fully stable 2.2GHz 1080s. It is the white whale.
 
From all the indicators, that is just a limit of the architecture. Nothing for it except wait for the next iteration with higher base clocks (and even then it doesn't guarantee anything - just look at some of the AMD cards that were re-released as new models).
