Hey all,

I recently upgraded the majority of my PC (motherboard, CPU / cooler, RAM, Graphics)

Intel Core i3-530
Corsair XMS 1,333MHz 4g (2x2g) RAM
Gigabyte GA-H55M-UD2H motherboard
Gigabyte HD 5770 ATI Graphics card

The initail problem I was having was that upon booting the PC, about 2 seconds into the bios my computer completly powerd off..?
I then discoverd that it was the graphics card causing this..as I removed the card and rebooted from the onboard graphics and it worked fine.
I tryed switching over PCI-E slots...and same thing happend.
I then put back my OLD Nvidia graphics card into the PCI-E slot and that works fine ...so its definatly up to the graphics card..
I dont even have the chance to enter bios, it shuts down that quick...or sometimes it doesnt even get to the bios...it just stays a completly blank screen..

And also a small problem im having now (while running all the new gear,but with my old graphics card) My computer will do
random power offs.....for no reason and with no warning....almost asif a powercut..??

I know its not CPU temp thats causing it, as its still running very cool...

Any suggestions with that issue too??

Any feedback will be very much appreciated!
 
Its a coolerMaster eXtreme Power Duo 650w

I think it was a bit of a budget buy (about £20-30 at the time) about 2 years ago while i was in hong kong. Has run my current PC fine (up untill now!). I did intially think it could be the PSU...but thorght i best get a 2nd opinion before I splash out..

Let me know if your after any specific information about the PSU..

Many thanks
 
Do it the old fashioned way! Get a multimeter and check it is providing the correct voltage and it is not fluctuating too much.
 
Ok :)

While were on the subject..any recomendations for a new PSU to comfortably run this setup...without invaiding the bank account too much..?
 
You'd expect a 36Amp 12v PSU to be able to cope with that setup. 36A is over 400 Watts of 12v power.


Are you overclocking anything?
 
Nah im not overclocking..

I just did a swap test into my brothers high spec PC...and it ran ok....so I presume it is a PSU issue...
 
you sure you have the power connectors set correctly to the graphics card? I'd check if the card is securely sitted in the PCI-e slot. Failing that, the card could be busted, or some issues with the PCI-e slot.
 
I did consider that, but like i said, i tryed both PCI-E slots. Connected, reconnected...

And then connected my old graphics card which works (so cant be the slot..)...
and then the card works in my brothers PC (so cant be the card)
