Replacement 310watt Power Supply HP Prodesk G4 400 MiniTower

[gamedev123]

Hi,

I have a Prodesk G4 400 with a 180 watt power supply.  In order to upgrade to a MSI GTX 1050 TI video card, I need to upgrade the system power supply to the 310 watt model for this unit.

Can't seem to find a way to order the replacement (I can install it myself - upgraded 4 HP systems over the past 10 years).

For that matter, I'd like to order several parts (card reader, internal wifi card) that I can install at the same time - can't seem to find a way to order them on the HP website.

I've tried HP partsurfer but a picture I found of the PSU showing part number #901772-004 (AcBel Polytech mfg) does not work.

Heeeelp!

Hi,

Try HP Part Surfer and use this part number.  922458-001

Hi Big Dave,

Off of this power supply image I found on an 'unboxing' of another unit.  I went back to the HP website and found that the upgraded power supply was a $3 more expensive option...  Doh.  But there does not seem to be a way to order this PSU aftermarket.

Hi,

See my previous post.

It's available at HP Part Surfer for $60.

BTW---The GTX 1050 is not going to run full speed in your PC since the x16 slot doesn't run at x16.

~10 minutes from problem to resolution.  Big Dave, youdaman!

Hi Dave,

I thought one was a full x16 and one was an x4.

Are both x4...?

[Big_Dave]

Hi,

I looked at the manual and it indcated that the x16 slot downshifts to x4.

[gamedev123]

Would that mean its operates at x4 all the time?

Do you have a link to the online manual?  The one I can find on the HP site gives me a loading error.

...a bit of searching brought of this thread which helps to answer my last question.

Thanks for all your help!

EDIT:  Just wanted to update this post.  The replacement 310watt PSU arrived.  It is the same size as the 180watt version.  It does not have a 6-pin connector for a GPU.  (And I won't be using a SATA to 6-Pin cable to power a GTX 1060...)

I've used Killawatt to record the energy usage of my system (i5 7500 w SSD) under load (before installing the 310 watt PSU) - it was an average of 50watts.  This leads me to surmise that my system (with SSD instead of HD) might function with the GTX 1050 TI and only a 180 watt / 80+ PSU.  Not recommended thought.

I did wind up installing the GTX 1050 TI with the old 180 watt 80+ power supply installed.  It runs like a charm with a max of 120 watts power draw, even when dogfighting in Star Citizen at 1600x1200 reslution at max settings (average was 105 watts). 

I'll keep the 310 watt PSU as a backup and likely install it if I see power levels go above 130 watts in some use case.

Hi

Congratulations on your successful result.

I have same problem, just bought a reconditioned Pro-desk G4 400 MT running win 10 (64-Bit) and a new MSI Geforce GTX 1050 Ti  graphics card which I have been trying to fit.  Unsuccessfully so far !  Have been searching on line for solutions -- when I came across this thread.  

Few questions :-  How did you get it to work;  white or black slot; did you have to alter any BIOS setting in order for the card to be recognised ?
