450watt

[XxMalch0xX]

Will a 450watt be enough for a i5 2500k gtx 1050ti 4gb and 8gb 1333mhz

I'm pretty sure it would be enough, yes. 

An I5-2500 CPU has a TDP of 95w

A GTX 1050ti uses 300w

so that would be 395, give or take a little bit.

As for ram, it never really uses much. It'll stay in the single digit watt range.

 

But don't forget the power of hard drives or SSDs.

 

If I were you I would consider a 500w power supply tbh

You're smoking something, MrReaver

 

GTX 1050 Ti peaks at around 75w - rule of thumb ... cards are allowed to consume up to 60w from slot + up to 75w from any pci-e 6pin  + up to 150w from any pci-e 8 pin

 

gtx 1050 / ti cards typically have only a 6pin or a 8pin pci-e connector, because they consume slightly more than the amount a card is legally allowed to take through the slot.. if they put a 8pin connector it's not because it's required but rather because it's probably the most convenient for the manufacturer.

 

even a gtx 1060 won't go over 125 watts.

 

the i5-2500 won't go over 100-120 watts in power consumption

 

mb + ram won't go over 20-40 watts .

 

So in theory a 450w is plenty, as long as it's a QUALITY 450w psu with enough current on 12v (from where the cpu and video card is powered).
