Upgrade of PSU from 180W to 400W or 500W for graphics card update

[graphuser22]

I recently purchased a Radeon W6400 engineering graphics card for my HP 295 G6 microtower only to find out that the PSU that came  with it is only 180W (L70042-002) . The card requires a minimum of 350W of PSU capacity. Having gone through similar questions in this community, I found out that there are possibly two options for an upgrade,

L69242-800 Power Supply - 400W

L05757-800 Power Supply - 500W

I wanted to confirm if either of the above two power supply are compatible with PC i have got? I don't want to be bitten twice.

Thank you in advance.

hi

I have a big doubt, if we look at this

HP 295 G6 Microtower PC 

Power Supply
180 W
EStar Libra2 EPA90 (Gold) Full range 115V/230V
310 W
310W MT Sirius2 ENTL EPA90 (Gold) Full range 115V/230V

Specs for your system show two compatible power supplies

There is a discussion about 400 watt power supplies by @NonSequitur777  here

@Prométhée beat me to it

I would like to add the the W6400 only needs a 250 watt power supply according to tech power up

I do not know if the W6400 would be recognized.  I assume your 295 G6 has a UEFI bios which should work.

hi @BeemerBiker 

I saw this subject, but obviously having no confirmation, I abstained, I was looking in the hp part, but after x page, I only found the 180w reference, so gave up!

Thank you for pointing me to techpowerup website. This is now a bit confusing. The AMD Radeon Pro  quick user guide mentions the min power requirement to be 350W in stead of 250W as on techpowerup.

I will have to first confirm that now.

hi

you must check with the manufacturer of the chosen graphics card
a graphics card can have different requirements depending on the manufacturer, ( if like many models, we can find different ones, several manufacturers ) and this varies, also depending on the configuration of the computer
