SFF pc in need of small dimension 400w or 350w TFX PSU upgrade

[jasperricco]

I have a Lenovo m91p SFF i5 2400 2gbx4 that I want to put in a EVGA GT 710 low profile single slot GPU in. my 240w TFX stock PSU wont run. I have a 300w PSU that dies out under heavy usage. I need help finding a 350w to 400w TFX PSU that's 6.9in long x 3.55 in tall x 2.8 in wide.
Exact specs on the stock PSU are.
input= voltage 100v-127v~/200v-240v__________current 8a /4a
output= +3.3v 8a~+5.08v 14a~+12v 17a________-12v 0,5a~+5.08Vsb 2.5a
max=86w max~204w________________________6w~12.7w
max=240w________________________________18.7w max
frequency= 60Hz/50Hz

I have a Silverstone tech 300w fixed cable TFX PSU 80 Plus Bronze Tx300 that doesn't quite do what needs to be done so I took everthing out.
I keep getting blue screen power failure's on just my stock intel HD 2000 without the EVGA GT 710 GPU in the unit. putting the Silverstone 300w back in solved that problem but "I NEED MORE POWER'' lol. to run the EVGA GT 710 GPU. anyone down to help a broke noob out. peace.

A 300W better quality PSU will be plenty.

If you want to go cheaper this FSP unit will do the job fine:

You can go with the higher quality Seasonic unit but it's more expensive:

With a gt 710 that system is 150w tops.
Your stock 240w psu should run it absolutely fine.

I already have a ton of things running off the PSU. two monitor's, xbox one controller, usb mouse, usb key board, usb WIFI, printer, vape pen charger. I need more then 300w. but thanks so much i'll still look into both of those.

 

[jasperricco]

with an EVGA GT 710. EVGA recommend 300w PSU minimum when I looked it up. the EVGA Tech said the same thing.

The gt 710 has a rated tdp of 20W + 95W from the i5 2400 so as madmatt said power consumption will be under 150W... you're way under the limit of the PSU with a great 300W unit.

 

[jasperricco]

with that 115w consumption still sticks me at 315w pull off of my PSU max. just at the threshold of what she can take. I still get blue screen or orange screen faults. looking in to it after restart. it a lack of power that caused it.

So maybe a 320w PSU would be perfect. I'm still looking around. thanks for the input.
