Upgrading V530-15ARR Pushing 180w PSU too far?

2021-10-13, 14:39 PM

I've had a V530-15ARR for a few years now which has served me pretty well. I'm something of a tab hog and notice that with enough tabs open I get the odd stutter. I'm intending to upgrade from the stock 8GB of DDR4 to 16GB. I've managed to source the same stick used by Lenovo as I hate to mix and match. So I now have another 8gb on the way. It then dawned on me that the PSU is only 180w, so my my first question is, do you think it's OK adding another 8GB?

 

As it only has a 256GB SSD, I was considering adding a 2TB WD Blue 7200RPM HDD as a second drive for extra storage, but I suspect I'll really be pushing the limit with this 180w PSU. I'd appreciate people's opinion on this.

Welcome to the community forum.

 

do you think it's OK adding another 8GB?

The power supply is spec'ed to handle a full complement of components. This model accommodates up to 32GB of RAM as well as both a 3.5" HDD and an M.2 SSD. So the power supply should be more than capable.

I know some similar models had the alternative of a 256GB SSD or 1TB HDD, so as an extra stick of DDR4 should draw a lot less than a HDD I'm sure that should be OK, I just wasn't certain if adding a HDD too might be pushing it. I have my PC on 24/7 quite often which I know pushes things a little further too on the PSU front.

I'm guessing a 7200RPM HDD and another 8GB DDR4 will pull in the region of 20w-25w extra, though perhaps someone here has a better idea.

I appreciate your advice hausman. Thank you for that.

 

I'm no expert in this area, but on the face of it, it seemed like I might be pushing it. I'd be interested to know if anyone else has upgraded this system or one similar to it though, and whether or not they've experienced any issues.

I couldn't find specs from WD but Seagate 3.5 HDD DATA SHEET says their 1TB 7,200rpm HDD draws about 5W of power.

 

And Crucial says, "As a rule of thumb, however, you want to allocate around 3 watts of power for every 8GB of DDR3 or DDR4 memory."

OK thanks. Maybe nearer 10w-15w overall then. I think many of these desktops are pretty stretched out the box with a 180w PSU, I was just worried a few basic extras might tip it over the edge that's all.

My RAM arrived today. Stuck it in. Got a HDD, but have left that out for now.

 

Surprising how 8GB RAM isn't enough these days. Although I think the problem is with the Ryzen chipset. They dedicate over 1GB of RAM to the GPU. Most people can get by with 8GB in an Intel PC, but I think 8GB isn't quite enough with a Ryzen. Essentially, my PC with 8GB of RAM was around 6.8GB useable, but around 14.8GB now with the upgrade.

 

People say you can't notice the difference between 8GB and 16GB, but I'm definitely noticing less of the odd stutter with my browser tab fest. Even the pointer was getting stuttery on occasion. That's with around 60 tabs open in Opera.

Agreed, I've been recommending 12 and 16GB for some time, particularly for systems with 2 memory slots.  Intel graphics can use 1GB playing HD video and 2GB when gaming.  

Fwiw, HDD can draw 20w during spin-up for a fraction of a sec, the rest of the time 5w or less.   Since your OS will be on the SSD, disable power-mgmt for the HDD to prevent spin-down and then up during normal operation.

Thanks for the tip. 

 

I did look to see if there were any other brand PC's out there with more or less the same specs as mine and I did see a HP running pretty much the exact setup only with a newer Ryzen chip on a 180w PSU. That only had 8GB DDR4 RAM, though it was across two 4GB sticks, so I'm guessing it would draw something similar. Plus it had a 256GB SSD and 1TB HDD, so I guess a 180w PSU can do it. Probably marginal, but possible it would seem.
