[SOLVED] Will a 110w gpu work with a 250w psu?

[Lolz4k]

I have a r7 370 2gb which needs 110w of external power but i dont think my 250w psu can handle it

Indeed it can not in the end it would be powering a CPU mobo ram gpu and all the vrm's and storage...

So if im buying a new psu how many watts should i buy

400w gold rated min

Given the little difference in price, I'd say go with 450W or 500W PSU, they will run cooler than a 400W PSU. And you are ready for future system upgrade as PSU can last up to 10 years.

250w can be enough if it's a good psu. Problem is the lack of a 6 pin PCI-e connector with 250w psu's.

What's the make and model of the cpu?

 

[David329302]

I mean your 250 could work if the TDP is very low on your cpu

Get a quality 550w, just to give yourself some headroom. Getting a bit more than you need means less heat and noise, PSU wise, and less stress on it.

A Corsair CX550m being the minimum quality unit, I would recommend.

 

[David329302]

I agree but if you dont have a PSU shroud get a modular PSU

250w psus are typically found in oem computers. What prebuild is this in? Model number.

And no, 250w is not enough. It's not going to have the appropriate connectors either.

I am sure your PSU hates you for it too.

 

[David329302]

I know right

Depends on how well-designed the PSU is, which in turn depends almost entirely on how long the manufacturer wants it to last. You can build a 300W or 700W PSU using almost exactly the same parts, except one will last 10-20 years in an industrial environment while the other might die a day after its 3-years warranty expires.

 

[logainofhades]

The CPU and GPU are using up 238w ish by themselves, which is nearly 3/4 capacity. Given how PSU's of such wattage are OEM, and questionable quality, it is surprising it still works.

Your going to fry this system in the long run this is not a recommendation at all

400w gold rated min

rating has nothing to do with quality, you have gold rated PSUs that are crap and bronze models with better caps and fans

a decent 450 will do, even 350 if it's a slim PC that won't be upgraded beyond this point, depending on the CPU and other parts

Rating has everything to do with how long the warrenty will normally last though... Thays why i always recommend gold at the least you will get a longer warrenty for probablems that arrive. No rating has nothing to due with the actual preformace just there quality standards. Thanks...

80+ ratings are on the honor system, there is no certification authority. Zebronics or some other third-world PSU vendor could put a 80+ Titanium sticker on their crap if they wanted to. While that would technically make the vendor liable for fitness-for-intended-use or false representation type lawsuits, good luck getting any money from off-shore companies unless you live in a country where the importer inherits the liability when the manufacturer has no assets within the jurisdiction to leverage sanctions against assuming you aren't the importer yourself by ordering from abroad.
