Upgrading HP EliteDesk 800 G1 and G2 is one of the best budget solutions for a 1080p gaming PC. With such a setup you’ll have a steady 60+ FPS gaming experience with many esports titles including Fortnite, PUBG, DOTA 2, CS:GO and League of legends.

Similar to Dell OptiPlex xx20 series gaming upgrade, you can upgrade both the tower and the small form factor model. However, the SFF model will deliver less FPS because you have to use a low profile GPU. That’s why the most popular approach is to use a tower version with a full size graphics card.

Between the two models the G2 has to be the better solution, at least on paper. However, real world gaming benchmarks show that the difference is negligible. At the time of writing the price difference between 800 G1 and 800 G2 is almost non-existent, so getting the latter version makes much more sense.

Now…

Let’s see what’s possible in terms of upgrading the graphics card, the processor, the power supply, and the memory of HP EliteDesk 800 G1 and G2 in order to build a gaming desktop computer.

If you are curious, you can check the hardware differences between the EliteDesk 800 G1 and 800 G2.

OK, let’s dive in and see what you have to do in order to upgrade.

Upgrading the video card (GPU)

The GPU is the most important part of this upgrade. It will boost the graphic performance of your EliteDesk 800 G1 and G2 and make those esports titles playable.

Let’s begin with two GPU options that make the most sense – they have a good price to performance ratio and don’t require any changes to the hardware whatsoever.

The best dedicated GPUs for EliteDesk 800 G1 and G2:

  • GeForce GTX 1650 4GB GDDR6 – Use this with the tower version of HP EliteDesk 800 G1 and G2. This 75W GPU does not require an auxiliary PCIe power connection.
  • GeForce GTX 1650 low profile is a 75W GPU that will work perfectly fine with the small form factor version of EliteDesk 800 G1 and G2.

*Currently the price don’t make much sense, but who knows. :/ May be it’s the future and the things are normal again.

The following table is our selection of possible GPU upgrades by NVIDIA and AMD that will fit inside the HP EliteDesk 800 G1 and G2 tower version.

GPU  model GPU Power GPU Memory EliteDesk model
MSI GeForce GTX 1650 LP 75 W 4 GB DDR5 G1/G2 SFF
ZOTAC GeForce RTX 2070S Mini 215 W 8 GB DDR6 G2 Tower
EVGA GeForce GTX 1060 6GB SC 120 W 6 GB GDDR5 G1/G2 Tower
Sapphire Radeon RX 570 ITX 150 W 4 GB GDDR5 G1/G2 Tower
Gigabyte GTX 1660S ITX 125 W 6 GB GDDR6 G1/G2 Tower
Gigabyte GTX 1080 8GB ITX 180 W 8 GB GDDR5 G1/G2 Tower

Couple of things that are good to know when upgrading the GPU.

All GPUs intended for the 800 G1/G2 tower are short version models – around 6.6 inches (170mm) or less. If you get a full length version (especially with back plate), there’s a chance that the card will block the front USB connector and some SATA ports. Dropping to the front panel USB ports and using right angle data cable will give you the option for longer video cards.

On EliteDesk 800 G1 Full length version GPUs will block the front USB connector and some SATA ports.

GPUs that have power consumption up to 75W will operate without additional power from the PSU. In fact, cards between 75W and 120W will work with the stock PSU. All our suggestions are based on the 280W model. If you happen to have a 320W or 400W unit, you can use more powerful GPUs.

Cards that are between 75W and 120W will need a SATA to 8 or 6 pin power connector to draw power from the GPU; above 120W you have to change the PSU. With any of these options your pool of possible GPUs becomes larger.

If you install a GPU that is more powerful than the one recommended by HP, there is a chance of damaging your PC. We take no responsibility if something goes wrong. All upgrades are made at your own risk. If you want to stay safe, use the HP website to order your components.

Upgrading the Power Supply Unit (PSU) 

Out of the box the tower model has two power supply options – 280W and 400W. These power supplies use proprietary connectors but have the same size as a standard ATX. This parameter alone makes the G1 and G2 popular among DIY PC builders.

Of course you have the option to leave the stock unit (which has no GPU AUX), but to accommodate a more powerful video card (one that draws more than 120W) a PSU upgrade is needed.

To upgrade HP EliteDesk 800 G1 and G2 (tower) power supply you need a standard ATX PSU and a 24 to 6-pin adapter cable. This is because HP uses a 6-pin proprietary connector to power the motherboard.

The chassis uses 4 screw mounting, following the ATX specs, so you will have no problem using any standard ATX PSU. Lengthwise you have the option to mount an even larger power unit – just measure before you buy.

The best power supply upgrade for HP EliteDesk 800 G1 and G2:

  • Corsair CX 450M
  • be quiet! Straight Power 11 Platinum 550W
  • Super Flower Leadex III Gold 550W
  • EVGA 600 BR
  • EVGA 220-GA-0750-X1 SuperNova 750

But what about the SFF model?

The 800 G1 comes with 240W power supply and G2 comes with 200W. These PSUs use a proprietary form factor and are not easy to replace with an aftermarket unit. We suggest you use the stock model and opt for a GPU that will work with them (see our table for suggestions).

Upgrading the Processor (CPU) 

intel core i5-4690, core i7-4770, and core i7-4790K

Intel Core i5-4690, Core i7-4770, and Core i7-4790K are all possible upgrade paths.

EliteDesk 800 G1 and G2 support a wide range of CPUs. However, we are focusing on models that will provide a good gaming experience with high FPS count.

Processor (CPU) upgrade for HP EliteDesk 800 G1

HP EliteDesk 800 G1 comes with an Intel Q87 chipset supporting a wide variety of CPUs – from a dual core Celeron, and 4th gen Core i7 to Xeon processors. However, the best CPU to upgrade your G1 is the 4th Gen Core i5 4690. This model makes the most sense when building a gaming machine from this EliteDesk model.

Currently most G1 refurbished desktops come with either Core i3 4130 or Core i5 4570. The 4570 is fine, and we suggest you keep it to lower your cost down. The 4130 is a Core i3 dual core model and it’s not perfect for gaming.

However if you have the money or find a bargain for either i7 4770 or i7 4790, go for it. They will boost the performance slightly and enable better video cards.

Another viable option for upgrading is to use Xeon. Xeon E3-1230 v3 is a great alternative to the 4th gen i7 and an upgrade over the i5 due to the additional 4 threads. Very often this model will be cheaper than an i7.

HP Elite Desk 800  G1 CPU upgrade options:

Model Cores (Threads) Frequency Turbo
Core i5-4690 4 3.5 GHz 3.9 GHz
Core i7-4770 4 (8) 3.4 GHz 3.9 GHz
Core i7-4790 4 (8) 3.6 GHz 4.0 GHz
Xeon E3-1230 v2 4 (8) 3.3 GHz 3.7 GHz
Xeon E3-1270 v2 4 (8) 3.5 GHz 3.9 GHz

Processor (CPU) upgrade for HP EliteDesk 800 G2

HP EliteDesk 800 G2 comes with an Intel Q170 chipset and supports 6th gen Intel Core processors.

The best processor upgrade for EliteDesk 800 G2 is Intel Core i7 6700. This is a fast and reliable CPU that will be great even with most modern games. There will be no major bottlenecks even with recent games. If you have the money and the PSU you can pair i7 6700 with RTX 2070 SUPER, RTX 3050 or RX 6600XT. Yes, there will be some FPS inconsistencies in some titles, but using a 1440p or 4K display will alleviate the bottleneck since there will be more load on the GPU.

Model Cores (Threads) Base frequency Turbo
Core i5 6500 4(4) 3.2 GHz 3.6 GHz
Core i5 6600 4(4) 3.3 GHz 3.9 GHz
Core i7 6700 4(8) 3.4 GHz 4.0 GHz
