Help choosing video card!
so i ecently got in my mind that i want to build a mini-it pc, i have all the components except the videp card, i can't decide if a gtx 645 or a hd 5850, ill be using a Silverstone SG05 with 300watt psu, now i've seem people use the hd 5850 with thtsame case without any problems, my question is will it run on that 300 watt psu? the rest of the specs below 1 core i5 2500k 8gb ddr3 (2x4gb stcks) Silverstone SG05 with 300wlim blu-ray dvdr-rw) 1 1tb 7200rpm HD or a 64gb ssd drive and foxconn h67s itx mobo am i cramping to much stuff that the psu can't hadddle it???? maybe a corsair h50 (if it fits and i have enough power to run it) so what do you guys think? possible with either video card i stated above????
I wouldn't try running an ATI 5850 on a 300w PSU. You could, depending on the PSU's specs, run an ATI 5670, 5570, and possibly a 5750.
As for the nVidia card, did you mean to type GTX 465? If so, that's a no go as well.
This is what the Silverstone website says:Quote:
Graphic card length reference:
* ATI Radeon HD 5670 - 6.7"
* ATI Radeon HD 5750 - 8.15"
* ATI Radeon HD 4850/4830/5770 - 9"
* ATI Radeon HD 5850 - 9.5"(ST45SF PSU recommended)
* NVIDIA GeForce 9800GT - 9"
* NVIDIA GeForce 9600GT/GSO - 9"
* NVIDIA GeForce 8800GS/GT/GTS - 9"
* NVIDIA GeForce GTS 250 - 9"
* NVIDIA GeForce GTX 460 - 8.25" (ST45SF PSU recommended)
Note for the GTX 460 (better & more efficient than GTX 465) and ATI 5850 they specifically recommend a different power supply.
They say the case comes with the SFX 300W power supply (which isn't listed on their site). The only SFX they list is the "SFX 45" which is a 450W power supply.
This page seems to suggest the SFX 300W was made specific for this case, and provides 16A on two +12v Rails. However the way it's worded doesn't make it entirely clear whether it's 16A on each rail, or total.
That 300W SFX power supply doesn't have at least two 6-pin PCI Express Supplementary Power Connectors that either of the two graphics cards, that you have specified, will require. This is a confirmation that it is insufficient to properly power the configuration you want to assemble. You shouldn't be running a power supply at close its maximum limit because it will accelerate its component aging (i.e. shorten its life due to excess heat).
The SST-ST45SF 450W SFX form factor power supply with 36 Amps from its combined +12V rail(s) is required.
