is 550W enough for FX-8350 & GTX 970 OC ?

[pipper47]

Hello guys,

I am planning to buy a EVGA GeForce GTX970 Superclocked.

My first question is: Will a 550W power supply be enough (rig below)? I know according to given TDP it will teoretically be enough, but as I read some tests, the maximum power consumption was way above the given datas... so will it be really enough?

Rig:
CPU- AMD FX-8350
GPU- EVGA GeForce GTX970 Superclocked ??? (Currently Radeon HD 7850 2GB OC)
PSU- OCZ ZT 550W
Motherboard - GIGABYTE 990XA-UD3
RAM - 2x4GB ... planning to plug in another 2 RAMs
HDD - 3,5" 7200RPM 1TB
SSD- Intel 120GB
Case Vent - 12cm
3 USB devices plugged in
1 DVD drive

Second question is: I have experienced 2-3 times while I was playing a games crashes.... Suddenly the screen just went black, but the audio was still playing....I had to turn off the power supply with a button and then switch it on to solve it... no other action had a reaction. So the question is: was that because of insuficient power supply or more likely a GPU problem ?

Thanks in advance

It's enough with a quality 550w but that one isn't the greatest power supply.

So your advice is to uprage a power supply also? ... and what do you think about the second problem I am having? Thank you.

A 550 watt is good enough, a linus tech tips video that I recently saw showed a 4 way sli 980 setup using a total system draw of 650-700watts. so your single should be just fine with 550. http://www.newegg.com/Product/Product.aspx?Item=N82E16817171092 I recommend this psu. tier one on the psu list, it is gold rated, and only $90 US. other options are listed here on the PSU tier http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html

hmm my PSU is not listed in there, but i googled another tier list and its among the second highest PSUs... so I think I will try to run it with my actual PSU, I dont want to spend additional money on another one... hopefully there will be no problem, but I appreciate your help

My GTX 970 (by Asus) just came today... I ran an OCCT test to be sure the power supply will handle it. I ran it for a couple of minutes and everything seems to work fine... but as I looked on a graphs generated after the test., there is this graph that makes me think.... http://s30.postimg.org/8uuquhjo1/2014_10_17_11h58_Frequency_GPU_0.png ... the max frequency is just 540Mhz as it should be 1 114 MHz .... anyone know why is that?

I was using Corsair VX 550W, Intel i7 870, 1 HDD & Galax GTX970. However I found that the system always reboot after I upgrade this display card. Finally I found that it causes in the PSU. And I just placed back to my older PSU Antec TP II 430W. And there's no problem now...... I really don't understand this issue

It probably was just issue with that perticular power supply, not with its wattage. I ran the OCCT PSU test with that OCZ ZT 550W and everything went fine. Hovewer I upraged to Corsair RM650, as I am thinking about future overclocking.

Well, this will be interesting... in the next couple of days I should be receiving my upgrade similar to your configuration. Thought my PSU would handle it but you have me worried. I am upgrading the mobo, cpu, video card, and adding a SSD to give me the following configuration:

CPU- AMD FX-8350 w/ Zalman 92mm CPU cooler
GPU- Zotac ZT GTX970 (Non-OC)
Motherboard- GIGABYTE 990FXA-UD3
PSU- FirePower ModXStream Pro 500W (Was considered OCZ when I bought it)
RAM- 4x2GB
HDD- 1TB 7200RPM
SSD- Samsung 840 EVO MZ 250GB
Case- Rosewill Challenger w/ 4x120mm fans and 1x140mm fan
2x Power utilizing USB devices (not including mouse/keyboard)
DVD RW Drive

I have not had previous issues as you have, so I may not run into those issues, but I will test my card when it comes in to see if I get low clocks as you appear to have.

Is coolermaster Thunder 550W is enough for the above system?>

I agree (I can't disagree) but realize that AMD FX processors can be power hogs. A stock FX-8350 can use up to 213W under load not overcloced! Check this link: http://www.bit-tech.net/hardware/2012/11/06/amd-fx-8350-review/7 You can see that an overclocked FX-8350 (4.8GHz) can use up to 364W. Just be cautious
