Power Supply for the following config

[Pbanks18]

Hello!

Computer config in 800D obsidian case (with about 6 fans running)
INTEL I7-3820 3.6 GHZ
8GB CORSAIR VENGEANCE 1600MHZ DDR3
BLACK LG 24X DVDRW
ASROCK X79 EXTREME4 3WAY SLI/CROSSFIRE USB 3.0 SATA 3 LGA 2011 INTEL
NVIDIA GTX550 TI 1GB PCIE

Power supply is a CX500

I recently purchased a GTX 970 G1 and 8GB of additional ram. I know people will recommend to get a new PSU but i was wondering how much wattage do I need? and any recommendations?

 

[Demosthenest]

seasonic 620. 55 bucks on amazon, best one under 100.

 

[zenx]

It should still run it, unless you overclock something.
If you really want to buy a new psu a 600w would be more than enough and if you plan further upgrades a 750w... but atm your systems peak consumption would be somewhere around 450w so it should be fine.

EDIT: You can just go ahead and check it out http://www.extreme.outervision.com/psucalculatorlite.jsp

whats your budget?

 

[Pbanks18]

Since i just spent about 400 on the GPU im guessing about 100-150 for a budget for the PSU

 

[tiny voices]

Get that Seasonic listed above.

 

[Pbanks18]

would the EVGA SuperNOVA 750 G2 be overkill?

@smudgy --- trying to steer clear from the corsair one.. from what i've read they arent that great and can lead to coil whining noises on the GPU...

DO NOT buy a Corsair CX PSU. They are just not good. THey use junk capacitors. We do not recommend them at all.

 

[zenx]

Yea, that's called propaganda ) Anyway I bought a CX750M 2 weeks ago or so.. totally satisfied (running a system similar to yours with an asus gtx 970)

 

[tiny voices]

Nope. Not propaganda at all. Failure numbers and facts speak for themselves. The primary caps are only rated at 40c, while quality unit's caps are rated at 100+. The CX units are just not good. Plain and simple.

 

[Demosthenest]

"Anyway I bought a CX750M 2 weeks ago" they work great at first, usually fail when they have 1-2 years.
Good luck with it.

 

[tiny voices]

Yeah, I would replace it to be honest.

 

[Pbanks18]

I have a CX500 and this computer is now 2.5 years old. hence, the upgrade to the GPU and ram to handle other games better (noticed that I was getting alot of lock ups when playing Diablo 3... you believe that?) So I guess i'll be going with the seasonic... looks reasonably priced.

 

[tiny voices]

That Seasonic is leaps and bounds above the CX units, and at the current price, it is a no-brainier.

 

[Smudgy]

sorry i didnt look up the prices .myself im running a thermaltake m series 850 running 2 290xs an never have an issue but people say thermaltakes arent that good

 

[Demosthenest]

psus get worse over time. It's normal that you don't encounter problems even with the worse ones at first.

The SMART M series is quite terrible in fact. I would recommend you get a new one ASAP. I have seen those units take whole systems out.

 

[Smudgy]

ok any suggestions on 1000+ watt psu

 

[tiny voices]

Why 1000w?

 

[Smudgy]

or solid 850+???

 

[tiny voices]

PM me if you want to discuss this. We shouldn't derail this thread anymore.

 

[Smudgy]

i always think more is better i wanna just get one solid no need for upgrade psu as i see it ill never run more than 2 gpu's
