Thanks. I thought as much

I'm doing some work for a friend. He has a PC that is the main workhorse. (Buissness no gaming) The PC has an I9 14900k with an EK Nucleus AIO CR360. I noticed that the tubes at the top of the block. Is it worth messing with? The Radiator is at the top.

RX 5800x i don't get it.

You will see massive improvements.

That's not the best power supply. I would replace that if you are going to spend money on upgrades. Try to get something at least teir C on this list: https://cultists.network/140/psu-tier-list/ For the CPU I would get the Ryzen 5 5600 (non x) for $120 For GPU I would look at the Rx 6700xt for around $300. If that's too much, let us know your budget.

What model PSU?

It could still be the power supply. Just because it can power low power devices, doesn't mean that's not the problem. Its probably the Motherboard or power supply.

Unplug everything but the power cord. Try starting it. If that doesn't work, see if it starts up without the GPU. Then one ram stick at a time.

Not worth it. Most laptops don't have interchangeable GPUs anymore. The ones that did took MXM graphics cards. Those cards were just not available at retail and were way to expensive on ebay. Best you can do is a laptop with a thunderbolt port and an external GPU. Otherwise just a cheap rtx 3050 laptop for $500 or less.

Try discharging the PC. Unplug the PC and hold down the power button for 15 seconds. If that doesn't work, try removing the cmos battery and then discharge the PC.

I got another really cheap DELL t5810. I upgraded with an $8 e5-1650 v3 as usual. In the past I have used GTX 1070s in these systems and it was a great pairing. This time I got too bold. The 1070s were over $100. Closer to $110. And I saw an RX 5700xt (reference) for $125. So I pulled the trigger. But I'm getting bottlenecks at 1080p Heaven and timespy ran great. But Hogwarts is getting slammed. I'm getting 50% - 60% GPU usage. COD is closer to full usage but drops into the 70% usage. I haven't tried other games yet. Any guesses as to which games will be bottleneck the worst? How much will higher resolutions help?

I don't know about the cooler, but I have put a GTX 1070 in a t5810 and in ran gear. I just put a blower 5700XT in one and that will get bottlenecked in some games. In Hogwarts Legacy I'm getting 50%-60% GPU usage.

Unless you're ready to drop at least $800, I would wait for the next generation of cards.

First things first, do you live near microcenter?

Average used price on ebay seems to be $330. No idea why. New ones are $360 for 2 free games. But it would be in a system. So there would be a little of an upsell
