Help Needed

Hi, 

Thanks for writing to us. 

The Vostro 270 slim tower supports 220w PSU (tested). A 300w PSU is for 270M (minitower). 

Though we have seen few of our customers upgrading the PSU which are not compatible by the machines (different models) and they worked, but for few it risked the motherboard.

Hi, 

Awaiting your response. 

Regards

he graphic card is nvidia gt 730 but it needs 300w power supply can i upgrade my psu and will my pc support it???

The recommended power supply wattage is 300, but that doesn't mean you need 300.

The only test I could find pegged total system wattage at high load at under 100 watts, and that was with a quad-core CPU. I think you can get away with your current power supply.

So can i install that graphic card in my pc without replacing my graphic card??

no.  Slim Models cannot upgrade power supply.

But can i install new graphic card(nvidia gt 730) without upgrading psu?

no

So can i install that graphic card in my pc without replacing my graphic card??

i ordered it but it wont fit in my cpu what should i do now?

Physical Parameters are just as important as power.  This is why I said NO it wont fit.  Even Mini towers have issues with cards that are more than 1 slot wide.

Some get around this by hacking the case.

 You have to literally hack the case and drive carrier to get other cards to fit.  VERY FEW cards fit in smaller cases due to this constraint.  There is a 25w limit for the smaller cases.This limit is absolutely on the SFF model because the Power supply is 220w.    All models can only use 1 slot wide cards. The tower can use cards with thicker heatsink but they cannot exceed 8 inches long when they have tall fans.

DESKTOP AND SFF WILL HIT THE HARD DRIVE BRACKET AND NOT GO IN WHEN A THICK HEATSINK IS ON THE CARD.

The SKI epic solution was to DREMEL OFF THE HARD DRIVE CASE and use tape to hold the drive in.
