PSU, GPU & CPU Upgrade?

[Matty34]

Hi there

I recently purchased an HP Pavilion 590-p0205a and was able to squeeze in an Asus Dual GTX 1070 8GB. I wanted to know if acquiring the 400W L04618-800 PSU will allow my GPU and AMD Ryzen 7 2700X cpu to connect and function together? Regards and thanks. Matt

@Matty34,

Welcome to our HP community forum!

Your HP Pavilion 590-p0205a as fitted with a Sunflower motherboard (SSID: 8433) is indeed compatible with the 400-watt power supply (p/n: L04618-800), but I don't think this power supply is sufficient to power your PC with an Asus Dual GTX 1070 8GB given its 150-watt TDP.

What you need is the 500-watt power supply with p/n: L05757-800.  You can purchase this power supply via eBay-Australia from this trusted Seller: New Power Supply Unit PSU 500W For HP ENVY Desktop - 795-0003UR L05757-800 AU | eBay.

@Matty34,

Well, if you can't return the 400-watt power supply, you can try it out and see what happens.

Look, your mileage may vary, and the 400-watt power supply may be sufficient to power your PC. Btw, the minimum power supply wattage recommended by Asus/Nvidia is listed at 500-watt: https://www.onecomputerguy.com/gtx-1070-wattage/.

My 1070 reached its maximum power of 360–390 watts with my i7-10700KF after I benchmarked it for an hour on my newer PC with a 600 watt power supply.

I believe I should be good with 400 watts because my i7 uses more watt power than my 2700X, but I'll try it and send it back if it doesn't work.

Thank you again.

@Matty34,

You're welcome, and if you wouldn't mind, please follow up how things went with the 400-watt power supply.

Hello, again

The PSU will arrive today or tomorrow, I added a extra fan to the side of the case to intake air to cool the pc and I was wondering If I could use a Fan splitter like this one?

Can I use this to power the exhaust fan and the new side panel one I installed?

Linked some photos of the progress

@Matty34,

This looks awesome!  You improved the internal airflow quite a bit -well done!

Yes, you can indeed utilize the "System Fan" 4-pin PWM to power your two cooling fans with the one-to-two PWM fan splitter cable you referenced with no issues whatsoever:

Thank you for sharing!
