I currently have a CiT 550w PSU, I have just upgraded my machine apart from the PSU. I have had Windows7 just lock up and/or restart and was wondering if the PSU was insufficient... i know the brand isnt considered much among people so I need an upgrade!
I understand I need good current/amps on the 12v rail. How many Watts are enough?
Unfortunately I am not familiar with the CIT 550 watt power supply.
We just had another thread asking about the OCZ ModXstream 700 watt power supply. I managed to find two technical reviews (It's usually the larger 750 watt model that gets reviewed). The psu is more than adequate for a system with an ATI Radeon HD 4890 video card.
