Adding to the remaining quality:
The connections are poor.
2x Molex for CD-ROMs, etc.
3x SATA
1x Mainboard
1x processor
If 2 CD drives so there will already scarce with the plugs, - especially if the additional graphics card also needs a power supply from the power supply. Thanks to the absence of 6 polar plug must be accessed here on Y adapter Adapter for the graphics card and since then never rich 2 ports.
Furthermore, I have brought in experience have the cheap power supplies apparently not an overload protection and because durchknallen times quickly. Now tell me times please someone like me a 500Watt power supply "just" about Laste in a way that it durchfetzt? So can really only be because the real power of this power supply is a little further below 500 watts :(
