What better Power Supplys are compatible with my Computer

[Joshx]

Hi,

I am looking to upgrade the Power supply unit in my computer (Product: OMEN by HP Desktop PC 880-p1xx) as I dont think it has the capacity to handle what I intend to do with my computer (development work, VR gaming etc), I used a power meter to measure the real time power consumption and on a high end game it was using around 400 watts, but I think it will use alot more than this when I get my second monitor set up as well as the VR headset - But I am struggling to find out what PSUs are actually compatible with my setup.

According to the HP specs page for my model, I have a Tampa2 Motherboard and an Internal 500w power supply.

What PSUs (around the 800w range) could I buy which are compatible with my computer? And how do I find out what PSUs are compatible with my setup so that I know for the future...

Thanks

Hi

Some popular and highly regarded power supply choices are as follows:

Seasonic,

Corsair,

EVGA,

Super Flower,

Antec.

All of the above power supplies will work in your system provided you verify current power supply dimensions against your relacement choice.

You may have to purchase a SATA power adapter if your PC has an Ultra Slim CD/DVD drive.

Gold rated PSs are great. Platinum PSs are even better.

Some of the above PSs come with a zero RPM fan mode which makes the units really quiet.

Hi,

You might consider the 750 watt platinum rated power supply HP offers in the 880 series.  It's a decent buy at $200 and will have all of the proper connectors.

HP Part Surfer has it in stock. PN 919937-800

Hi

Check out the HP PS. I have seen HP use Delta components on the Omen PCs. Delta makes very good PS's.

I am running a 650 watt PS which has the zero RPM mode with the following components installed.The PS fan only spins at boot. The PS runs very cool even when overclocking the 8700k to 4.8 GHz and stress testing the 1080.

i7 8700k

GTX 1080

Kraken x62

4TB HDD

Soundblaster XAE-5

1TB 960 EVO

500 GB 850EVO

32GB RAM (4 x 8GB)

Lots of RGB LEDs.

Thank you. I was looking at this PSU (Apparently it can be delivered on Tuesday which is good):

https://www.scan.co.uk/products/750w-seasonic-focus-plus-gold-full-modular-80plus-gold-sli-crossfire...

The dimensions fit my current chassis: The PSU in the link is 150 x 86 x 140 mm (WxHxD) and my current PSU 145 x 155 x 95 mm (LxWxH)

It seems to be compatible with my Tampa2 Motherboard (both 24 pin)

Do you think the 750w PSU in the link will be compatible with my current setup?

After some research last night I was seeing some people talk about how getting higher wattage PSUs arent necessarily better, so I think 750w is probably what I need.

This should hopefully be the last question I need to ask, thanks for your help so far!

Hi

You're very welcome.

The Seasonic power supply looks good.

750 watts is more than enough power. You could run an SLI setup with this wattage.

Your PC's product spec site looks like you have a standard optical drive so you may not need a SATA power adapter to provide power to the optical disc drive.
