Need Help ASAP Please!

Hey guys, I have a dilemma... I recently "upgraded" from a GTX 750 ti 2GB with ACX cooling (1189 Mhz base clock speed) to a Sapphire Radeon R9 280 3GB with Dual-X cooling (940 Mhz factory OC speed). My main concern with this card is that it gets super hot. My 750 never broke 50 degrees celsius even under heavy load because my case is well ventilated and I have several 120 mm fans sucking all the hot air out. However, this new card reached 74 degrees celsius then proceeded to shut my system down. I decided to turn my fans around to blow the air directly onto the card itself. This helped somewhat, reducing the temp to around 50 degrees celsius, but when I run Valley benchmark it rises to 65 celsius then shuts off. I then noticed once the Bios booted that I was getting an error message which says "Power supply surges detected during the previous power on. Asus anti surge was triggered to protect the system from unstable power supply unit"... I don't see how the power supply could be the problem. The R9 card recommends a 500 W PSU, whereas the one I am using is a 610 W unit (which I had no problem using the Nvidia card with). That's pretty much everything I know so far. Any recommendations or suggestions would be greatly appreciated. Thank you all for your time

What PSU do you have? 74c isn't that bad when overclocked as it hits 70c or more stock.

If it is just shutting off it is most likely a too weak or very poor quality PSU. So, what PSU do you have?

The 280 is safe at 85c put I would keep it under 80c so 65c is good and not the problem. What make and model is your psu? Definitely a psu issue.

Shamar Holtz · May 3, 2015

Fisr thing you need to know is that it is impossible to compare the 750 ti TDP to the 280 which draws far more power. the R9 2xx series are very high power sonsuming cards. Your PC isn't getting enough power so it is turning off your PC to save yourr parts, mainly your graphics card.

Post your full build, you will need to underclock your R9 280 so it will use less power and until you can get a bigger PSu you'll have to do that

Hey guys, here's a link to my PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817152026

disturbed force · May 3, 2015

Yup, you need a new psu.

Christian Devasher · May 3, 2015

Really? Okay, that's on my list. Any suggestions? and explanations as to why this one isnt powerful enough?

Shamar Holtz · May 3, 2015

Well one of the biggest reason is because it isn't at least 80+ Bronze certified to hold it's shit when it needs to

disturbed force · May 3, 2015

It a really cheap and low quality psu and likely does not output what it says it does. Here ia a tier list to give you a guide line of what is good and what is not http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html .

It looks cool as shit but it cant put out...pun intended

The motherboard itself called it an unstable power supply. I think your power supply has issues and is unstable.

This is a good one

disturbed force :

This is a perfect one OP

Christian Devasher · May 3, 2015

Would the 550W be enough to power the card and everything else as well?

Shamar Holtz · May 3, 2015

Yes it will be enough, the problem with yours was it says 630w but it wasn't really drawing that much, it was shit quality.

Even a GOOD 500w PSU will power a 280 and all the PC as well

disturbed force · May 3, 2015

Christian Devasher :

Yes it is a very good gold rated psu and will handle a system with a 280 no problem.

Christian Devasher · May 3, 2015

Alright, thank you guys so much for your help! You all are lifesavers. Hope you all have a great day/night!

disturbed force · May 3, 2015

No problem man, anytime.

Happy gaming mate! Cheers.
