Will HD 5450 work with a 160watt PSU?

MrInferno · Jul 17, 2016

Hello fellow enthusiasts, I have an HP Slimline S3720F which I have been wanting to upgrade the graphics. This is by no means going to be used for anything other than just simple browsing, office, videos, etc. The integrated Geforce 7100 just simply can't keep up with Aero and playing a video (gets really jumpy). My only problem is that this only came with a fairly low powered 160watt power supply. I have a spare HD 5450 fanless version lying around which I would like to put in here, but I don't know if there's even any wattage left to spare for the 5450. Would I be safe using the graphics card in this or do I have to upgrade the psu?

Specs:
Windows 7 64bit
Core2Duo E6550 2.33Ghz CPU
2 x 2GB PC2-6400 Ram
500GB Hitachi 7.2kRPM HDD
DVD Drive
Integrated USB wlan card

This is the graphics card I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121476&cm_re=asus_hd_5450_512mb-_-14-121-476-_-Product

short anwser. no it won't. You need a much better PSU in the 400 watt range according to AMD.

the chart here says the card can use 160 Watts on it's own. so no.[/strike]
I could not find a 400W psu for that system chassis, I would suggest a new case and power supply.

*(update) I found some cheap 350W PSU at Wal-mart but I cannot suggest them.

I stand corrected

R_1 :

In that chart is total system power.

If I can't use the card with the current PSU then how would I upgrade the power supply? Aren't these SFF cases built with proprietary PSUs?

no they too are built around standards in this case Flex ATX. aka Mini ITX
I found some 400Watt power supplies. search for Flex ATX or Mini ITX power supplies

the way I see it now you have two options. replace the power supply or replace the case and power supply (standard ATX)

I'm going to have to replace only the power supply because I like the small size of this current case. It fits just perfectly on the desk I have it on in living room.
