I'm getting a 7950 soon and was wondering if I might need to buy a new psu?

Can anyone tell me if I need too or not?

My system specs are right now.

MSI Z68A-GD55 M-board
16Gb Kingston hyper X 1600Mhz memory
1TB Hitatchi sata 2 HDD
2TB Western Digital sata 3 RED HDD
120Gb Kingston Hyper X SSD
120Gb Crosair Force 3 SSD
HIS 6950>70 GFX
Crosair HX 450W psu
Sound Blaster Fatality sound card
Antec Kuhler 920

If anyone can let me know if I will need to change psu it will be appreciated

I was thinking about that

. It's just the price of psu's just now :rolleyes:

there a bit pricey. Especially on top a 7950,

Also my computer crashes sometimes. It's not regular sometimes it can be on for days or weeks without it happening then all of a sudden it just crashes.

I'm thinking it might be a dodgy program in the background that's doing it?

If you are after a cheap 550W PSU I recommend the XFX

I would like a modular psu so it's not full of cables in the case. Also theres not much room in my case

You'll be fine, my GTX 680 and i5 3570K both heavily overclocked barely draws 400w! I have a meter reader here telling me the wattage I'm pulling from the wall right in front of me at all times. Of course you got to take into a count of the efficiency rating of your PSU.

Good, to know cheers

, still need to find the problem with the system crash now if it's not the power situation

It's been annoying me for sometime now.

What kind of crashing? Black screen? Blue screen? system restart? And in what situations does this normally occur? Give us some info and maybe we can help you

Try running at stock and see how you get on, you might need a bit more vcore on the CPU.

I have ran it on stock and it stopped for a while and I thought the problem was away then it started doing it again.

It happens when im just watching a film or surfing the internet, then just freezes, it doesn't let me do anything, I have to restart the system to do anything again.

Sounds more like a driver issue or driver conflict. If it continues I would try a fresh install of windows and see how you get on after that. I wouldn't jump straight to hardware problems in that situation

How old is the PSU?

Andy_1995 · 14 Mar 2013 at 23:01

its a few years old, but it's only had about 4 months use the rest of the time it's been in a cupboard.

Andy_1995 · 14 Mar 2013 at 23:23

If it happens one more time then it's getting wiped
