Would a 7950 run on my 450w Power supply?

[GAMER_1]

Can a 7950 run on my Silverstone SFX Gold rated 450w power supply? I have 37A and it supports continuous 450w power output. It has dual 6-pin and a single 8-pin PCI-E connection.

If it can't, can the 270x run on 450w?

Yes, it will run properly

Here is Guru3D's power supply recommendation:

Radeon HD 7950 - On your average system the card requires you to have a 500 Watt power supply unit.
Radeon HD 7950 Crossfire - On your average system the cards require you to have a 700 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

This is Guru3D's generic power supply recommendation for the R7 and R9 series:

AMD R7 260X - On your average system the card requires you to have a 450 Watt power supply unit.
AMD R7 260X Crossfire - On your average system the cards require you to have a 650 Watt power supply unit as minimum.

AMD R9 270X - On your average system the card requires you to have a 500 Watt power supply unit.
AMD R9 270X Crossfire - On your average system the cards require you to have a 700 Watt power supply unit as minimum.

AMD R9 280X - On your average system the card requires you to have a 550 Watt power supply unit.
AMD R9 280X Crossfire - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

It's a bit tight. Building new, I certainly wouldn't pick a 450, but if it was there I'd give it a go.... just take it easy and no OC ofc.

I don't think you'll have problems with it since it is 80+ gold unless you are thinking of overclocking as JackNaylorPE says
