The best price-performance 750W PSU out there?
Dont think 750 is enough for a gaming pc.Many of the z87 mothervoards eat up a lot of Ampers- up to 350w + 350w for the GPU + 100w processor + Ram + Hdd's and youre out of power.
I got the 1300w G2 ,why not ! the price difference is not so big 30-50 euros and it will be silent .
Flat cables ? maybe shorter i had to compress them in front of a 140mm fan,thinking about cutting them short later,when ill have time,dont have the will to solder 50 wires at Once.
750W not enough? You can run a 780TI on a 500W system quite comfortably, 750W will give plenty of room for overclocking. I would only go above 750W for multiple GPUs now (I used to have a dual GPU in my system before getting the GTX680).
Agreed, most people i know run overclockered sytems of 650w psu's. Only real reason to go beyond this is if you have an awful lot of power hungry parts or dual gfx cards.Quote:

Corsair tx 850 power supply
This shows that anything over 650 watts is unnessisary.
Completely agree especially as PSUs are more efficient above 20% load. Buying an overkill PSU actually lowers the efficiency of the rig. Much better to spend extra money on a 80 PLUS Platinum than a higher watt PSU.Quote:

Whilst I agree that MOST people don't need anything greater than 650 watts these days, it's flat wrong to suggest that higher capacity PSUs are unnecessary.Quote:

650w or 850w isn't going to make a difference with a power draw of 500w anyway. This PSU will still have around 90% efficiency. So yes it would be better to go with 850w for future upgrades
Well that assumes a couple things. One that they will upgrade, two that the cost of this PSU vs a smaller one now is marginal and that the margin is such that at the point of future upgrade the cost of a new PSU would be prohibitive. The thing is saying buy it to be future proof is only worth it if you are ever going to buy a second gfx card. And you will do so sooner rather than later as after all even the best of them lose efficiency in time.Quote:

Looks a good model, if I was in the market for a new one I would consider this.
As with others my 750w PSU runs my heavily clocked machine with 4 optical drives and 3 hard drives.
