I think I've found a glitch in the configuring process

[Bookamn345]

Hey guys! So I was configuring a PC and I came across some kind of glitch. So I have picked a GTX 770 as a GPU and a Corsair 550W Power supply. Now when I go to proceed it says "Due to the power requirements (AMPS,) the power supply you have selected is not suitable, please increase your PSU size or change to a higher spec model." No problem right? I'll ugrade to a 650W power supply. Once i've done this and proceeded another message comes up saying "You have selected a 650W power supply, but based on our calculations you actually only need a 550W power supply." What. Is this a glitch or should I go ahead and get a 650W power supply at a little extra cost or go with a 550W power supply even with the 1st message that came up?

I've asked about this before and an Admin replied "sorry for the confusing messages. There is an AMP issue with the VS series and high end GPUs, we have had to put on this message to avoid issues."

So best stick with the 650W CS power supply.

Thanks for the help!

You will need the 650W PSU, although the 550W PSU would be enough on pure wattage, its does not have the AMPs to power the NVidia cards
