The GTX 760 uses 160w with a 6-pin and 8-pin pci cables(that one screwed me up cause my psu has only 6-pin connectors).
I'm very low on money so I was trying to find a 14/16pin psu and only found the VS450, can it hold a GTX 760 with a Pentium E6700?(i know, bottleneck)
If you install this unit into a chassis with a good airflow and manage to keep the internal temperatures below 30 degrees Celsius, it will easily outlive the provided warranty. However the quality of your mains grid plays a significant role in this, as well. If the power quality in your area isn't high enough (lots of power cuts and/or brownouts), then you better use a quality UPS to power not only the VS450, but every electronic device you have. Voltage surges and brownouts are a leading cause of PSU failure.
In other words, it will, but far far better to invest a bit more, even if you have to save up, for THE base of your system. Maybe a holiday or some promo deal will get you a much more well rounded power source.
