Corsair CX 500 & GXT 570/GTX 560 TI

[MisterMac]

Hi,


I've currently got the following:

i5-2500k - OC 4,7 GHZ - 1,32/1,33 VCore (Seems to droop a bit time to time under stress test);
2x4GB Corsair Vengeance 1,5 V CL9 1600 MHZ.
Antec 620 H2O Kuhler
One Elderly WD 640 GB 5700 RPM SATA2.
ASUS P8Z68 V Pro
A cheap ass hitachi DVD R/W Drive.
XFX HD 5750


Extra Fans plugged in system:
CoolerMaster SickeFlow 120 MM
CoolerMaster BladeMaster 80 MM

Now, for PSU i have a CX 500 - it was bought in feb 11, so it's NOT a V2 sadly.

I'd like to upgrade to GTX 570/GTX 560 TI(HighEnd Gigabyte OC/EVGA OC versions) within a week.
(Good offers finally happening).


Will my little CX 500 Handle it with my OC?

Reading idontknow's scaling watt thread made me scared as shit.

Will it handle it? if so, will it BARELY handle it (aka upgrade as soon as funds allow it to something better)?

Am i pushing it like mister 2X580 on a Seasonic 650W?


Can i get it, see if it runs stable and if so yay, without damaging too much - if it turns out to not be stable?

Halp anandtechmasters, halp.

EDIT:

Now before people say KILL A WATT KILL A WATT!
In my territory, finding a decent one is only thru electricity companies and price there is a 80-90 bucks.
Something i'd rather not shell out just to "test" my current loads.

I am not sure what the first versions made on the 12v line but newer ones only make 34 amps which is very low for a setup like yours. 34 amps is only 408 watts. with my stock 2500k and stock gtx570, I can sometimes hit around 360 watts for a peak at the wall. with any significant overclocking on both the cpu and gtx570 I could easily hit peaks close to 450 watts at the wall. that would push your psu almost to the very limit of its rated 408 watts. and again I am not sure if this first versions even made that much. of course after some time they will not make the full rated power anyway.

I would probably just get a 6870 or 6950 2gb in your situation. as long as you did not unlock the 6950 gb or do some extreme ocing, it would be fine for your setup. I would personally back off your oc on that 2500k a bit just to be safe though. you are never going to see the difference 4.7 gives over 4.2 or 4.0 anyway.

At full load it'll be stressed very near to the current limit on the 12V rail. I would not risk it. Even if the PSU would handle it now, the accelerated aging of putting the PSU to high loads would take its toll sooner or later. If you can afford to upgrade the video card, you can probably also afford to sell the CX and get an XFX Core 650 for $60AR. That'll last you five years.

If it was availeble, then yes, easily.
Especially at that price, but i'm not - i'm in a wellfare state in EU, so slap 30-40% on all prices comparing to newegg/tigerdirect without MIR 😉.


I spoke to a friend who still has a q6600 and 9800 GTx2 setup in a lovely Closed WC Loop, and he wouldn't be too afraid from pushing it - it'd be rare that i'd get that high?
Assimung 200 W load from the 570/560ti + 140-160 CPU OC + maybe 50? 70 from system? - it does take me a bit high range wise - i admit.
But he said if it was stable, i could run and look to buy a decent better 650/750/850 (depending on SLI or not futureproofing) whenever i got extra cash over the next period of months. Is that pushing a tad bit much into the grey zone?

I'll probably look for prices for my HD 5750 aging GPU + the CX, and after fetching a buyer go for a 750 TX/HX Series + my 560 TI OC or a Stock 570.



Are the OEM Seasonic - Silver Power SP worth anything comparing to a TX/HX series from Corsair?

with your cpu oced like that and a gtx570 you would be pushing that psu pretty hard at times with only 34 amps. for just a basic system with a gtx570, the minimum recommended is at least 38 amps. throw in some overclocking on the cpu and gpu and you will need more than that to have some decent wiggle room.
