OK here goes - have asked elsewhere and keep getting directed back to hexus for help. I bought a PC 2 years ago as follows:
AMD X2 4200+
1GB (2x512) PC 3200 DDR2
2xnvidia 7800GT SLI
500GB 5400rpm HDD
**Tagan 420W PSU**
Through a variety of component failures and upgrades, my system now looks like this:
AMD X2 6000+
2GB (4x512) PC 5400 DDR2
2x nvidia 7800GTX SLI
500GB 7200rpm HDD
**Tagan 420W PSU**
The last upgrade I made was to bump up the processor and add 2 more RAM sticks. Now the computer occasionally powers down (as in just completely stops and turns off) without warning.
Have done usual (run virus scans / adware etc and checked temps) but all seems ok there, but given the amount the machine has been upgraded I'm having a stab that the PSU is drastically underpowered. So questions are:
1. Do you agree that the PSU is too small
2. If so what would you recommend (any silent solutions would also be appreciated but not essential)
3. Size matters? Do I need to look at a specific PSU size dimensionally to fit my case.
Any help would be enormously appreciated so thank you in advance!
