GPU for a 150W system

[sbi85]

Hey guys,
I just got a new system with an Antec ISK310-150 case which has a 150W PSU.
It does have an iGPU of HD1000 in the Intel G860 to came with but if possible I would like to have a dedicated graphics card as well but not sure what it could support.

It needs to be low profile to fit in the case. I wouldn't need it for heavy gaming just some simple ones.

Just to make sure we know the wattage needs here is the rest of the configuration :
Case: Antec ISK310-150 (customized - two case fans installed plus anti vibration feet)
Motherboard: ASUS P8H77-I (mini-itx)
CPU: Intel Pentium Dual Core G860 3.0GHz
RAM: 4Gb (2x2Gb) Corsair 1333MHz DDR3
HDD: 320Gb 2.5"
Panasonic DVD drive
Akasa low profile CPU heatsink and fan

I thought of GT430 first but not sure if the PSU is enough, so maybe a GT610 would be better.

Any tips or suggestions?

I was wrong.

the gt 610 is pretty much the max, the gtx 750 would blow up the machine.

The pentium takes 65w and the 750 takes 60 watt drawing 125 just for those two components. I did some looking really quick, your system will draw close to 200 watts with the 750.

Radeon HD 6670 ...

wouldnt the HD 6670 be over the limit? its drawing 66W according to google.

From here ... with an OC'd i5 2500K


TechPowerUp has an average 42w --- with 58w max under Furmark stress testing. Moral of story: Don't 'play' Furmark 😀

Those Turks cores are highly efficient and the basis for the Trinity/Richland APU on-board graphics engines (and also the FirePro V4900 pro card).

I'm guessing they could also take a bit of an under-volt if you were so inclined. I wouldn't get to carried away with that, though, as it would likely artifact and/or crash if you went crazy with it.

edit: Low profile 6670s start at $75 at Amazon with some models zooming past $120 :lol:

They must be good !

^^and 50W for the peak 'gaming' load
that is till quite ambitious seeing as the psu only has 120W (10A) on the 12V rail, page 4

might just work thou 😀

I did a calculation using this site: http://extreme.outervision.com/PSUEngine

the weird thing is according to this calculator, without the graphics card the system needs 176W energy which I find hard to believe. Here is the setup: http://prntscr.com/3y96h8

This is probably the reason why I fear that the HD6670 with its 50-60W might be too much. I fear even a GT 610 with its 29W is not a good idea.

Anyone had any experience in this?

Still any advice is appreciated guys. thanks for the feedback so far.

What if you used a consumption meter (like Kill-a-Watt http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001 ) to measure the power draw of the system as it currently is under heavy cpu load like Wprime or prime95 for example. Factor in the psu inefficiency, maybe 85%, and you get the psu output power. That would then in turn give you some idea how many watts you have to spare for the GPU.

or you can invest in an okay-ish 400w PSU that will fit most standard low profile cases? They run around $40

toms own build using the Antec ISK300-150, with same cpu and low profile radeon 7750, system power draw from the wall under cpu+gpu load 113W
😀D

well thats really ressuring.
Not sure I would spend the 60-70pounds on the 7750 for this config but the GT430 has slighly lower wattage needs and its just a bit less than 30pounds.
Since I would not use this computer for heavy gaming I guess the GT430 would be actually enough. Brilliant.

if you're not using it for gaming get the 5450. I think it's like $30 or something like that.

I think the max would be Dota 2
