Does the nvidia GT 520 require any power supply cables to be attached to it or do only the mid/higher end cards like HD 6870 require psu cables to be attached?Thanks
for low end cards, you dont need an additional 6 pin or 8 pin power cable for it. It is only for mid range and high range cards that need additional cable for it. For GT 520, you don't need it.
No, the GT 520 is a low-power consumption card that doesn't need an external cable. It draws all the power it needs directly from the PCI-E x16 slot. Same story for the GeForce GT 430, GT 440, GT 630 and Radeon HD 6450, 6570, 6670 7750. None of those cards require external power. The GeForce GTS 450, GTX 550 Ti, Radeon HD 7770 and Radeon HD 6850 require a 6-pin cable. The Radeon HD 6870 and GeForce GTX 560 require two 6-pin cables, not just one.
