Best GPU for 1080p when using Corsair SF 450w SFX 80+ gold

cordes85 · Apr 9, 2016

Hey there, im asking this question as i cannot find enough about Corsairs 450w psu online, other than most people rate them better than silverstone, so i chose them instead,
I currently have;
Intel 6500
Asrock Itx H110
Corsair 2400mhz ddr4 2x8gb
SSD - 240gb crucial BX200
HDD - Seagate 2tb 7,200rpm sata III
Silverstone SG05 Black
1x Red corsair AF120mm fan
Scythe big Shuriken 2 rev.B
Samsung SN406ab Blu ray slim optical
windows 10
a slimline cable for the optical drive and some arctic thermal paste,
and the 450w Corsair SF 80+gold

For the GPU, what can i go for?
I only want to play games in 1080P at best settings i can, i dont want to spend more than £300-350. Should i go for the Gigabyte 970 itx version, or even the smaller Evga 970 Sc 2,0 acx?
Will this PSU handle this card fine, and leave enough spare, dont like the idea or maxing out the PSU. Any other suggestions about my build is welcome.

Best regards,
Cordes85

Normally, a 500W PSU is the minimum recommended for the GTX 970. But if this is your PSU: http://www.corsair.com/en-us/sf-series-sf450-450-watt-80-plus-gold-certified-high-performance-sfx-psu
...it has the +12V rail of most 500W PSUs. I would not be afraid of using it myself with that system. This reviewer gives the SF line a thumbs up. http://www.kitguru.net/components/power-supplies/zardon/corsair-sf-450-and-sf-600-psu-review/

But I would not OC with that PSU.

cordes85 :

a 450w could handle a 970, no overclocking of course

BUT only if it was an actually good unit, with strong internals

without some reviews I am reticent to say if that psu is actually any good

You really need at least a 500w with good reviews

The Gigabyte 970 itx http://www.gigabyte.com/products/product-page.aspx?pid=5252#ov recommends 400w psu, would this be better to use instead of full fat 970?

cordes85 :

it needs an 8-pin

make sure that power supply has a 6+2 or two 6-pins to adapt to a single 8-pin

The PSU comes with 2x 6+2pin connectors.

cordes85 :

I think you are alright with either one. The mini gets by with requiring a lesser wattage PSU because the clocks are not as high as some GTX 970s. My Evga GTX 970 FTW+ for example had a base clock about the same as the Mini's Boost clock in gaming mode; 1216 MHz.
