I got mine running on 500W PSU, it works fine.

Yeah

I feel you man. Other brands also have disadvantages lah, but banning CM PSU just for some cases is nothing more than fanboyism that many people hate to admit to be one

And that 300w is not enough for motherboard, CPU and HDD? Your GC won't always be operating at peak load.

My friend runs 5830CF + 955BE + 2 HDDs + fancy fans around 4 pieces and a pair of CCFL tubes on Vantec 600W, no problem at all. Mind you gtx460 consumes considerably lesser power than 5830. About the CPU, it's the same case, the CPU is not going to be peaking all the time. It might pose some risks back in a few years ago, but as of the smaller dye fabrication now it's no biggie, as both CPU and GC are the two hardwares that feed on power in a system mostly.

I have never heard of that, but I think many people will not believe it, or the truth is only grain-sized as I bet 95% of people here have never actually switched off the PSU itself for as long as their occupation on computers.

It's a totally useless idea for someone who wanted to buy a rig.

1 month post the release of 5830, now it's time to wait for a few more months for the 'symptom' to kick in?. Heh don't talk about PSU lasting yada yada to me man. Do I need to tell you how my CM EPP 500W still alive and kicking after 2 years powering OCed E8400 to 3.8Ghz + OCed GTX260+? Many called that as impossible, my PSU was gonna explode ohnoeez, but it didn't. Most 80+% PSUs are designed to maintain operating consistency well far above the commonly believed 'ideal' load of 50%. GCs and CPUs power consumption are decreasing, and surprisingly I noted a stupid thing like the standard of required power consumption for a rig with a GC is changing, i.e increasing. And you should correct the info you stated, 5770 consumes relatively around 9600GT, not 4850 which is backed up by the need of only one PCIE connector. With all the HD4000 series you mentioned in your friends' cases, I wouldn't be surprised. Back then nvidia GT9000 range was better at power consumption if compared to the direct competition of HD4000 series. But like I said, things have changed for the better, GTX460 consumes somewhere between a 5770 and 5830. If it is already proven that a 600W could power up 5830CF safely, then why not the lesser GC? OC opportunity? That's why it is a must for a TS to state whether he/she would be OCing his/her rig, then only people here would recommend what wattage is deemed necessary, we don't just simply go straight to the point simply by looking at the GC + CPU

Err no, it was done on CM EPP 500W, the PSU that many people were skeptical before With only roughly 420W stable power produced, it is certainly more than enough to power up the combo I mentioned, plus the PSU survival up until now (around 2 years already) should give you the idea that reviews are not everything once you ahve experienced it yourself

I wasn't saying at you lah, my point was to inform people that don't take reviews 100% as they are Dual core or quad core, even hexacore it doesn't matter much. I blew a duallie before for pumping over 1.45v so I know how serious it was to play with voltage, the best thing is to avoid vcore tweak unless you are equipped with proper coolant.
