Used PC builds: What are they worth?

crimsonstag84 said:The new G1610 is roughly $77 😉

So realistically, $60.

What kind of power supply are we talking about?

Look, if that's actually the case, then it's a complete 180, $45

So, I picked up this rig just last summer, and it's still fully covered under warranty... but seriously, what was that whole thing about the store having a 25% discount? I have no clue where you guys are even pulling these numbers from, honestly.

Well, take a look at the prices on eBay or compare them to what things cost brand new today. Personally, I’d only consider a 25% discount if the machine were practically new—like, used for maybe two months. But if we're talking about a low-value item, why would anyone bother with a measly 50-$33 who has the patience for that kind of hassle??

This is how I’d finally build it...

CPU: $50(whatever cheap one is at Best Buy $77)
RAM: $60(cheapest sticks at Best Buy $93)
Motherboard: $67(basic model from Best Buy around 300-$117)
HDD: $17
Optical Drive: $17
PSU and Case (probably just junk): $33

The whole thing is maybe 2/3 the price of a new rig.

RAM: $60(cheapest stuff they have at Walmart $93)
Motherboard: $67(the cheapest $300-$117 option at Micro Center)
HDD: $17
Optical Drive: $17
PSU and Case (probably junk): $33

That whole setup would be about 2/3 what you'd pay for something brand new.

I mean, that sounds a little more reasonable now, though we're talking about two separate drives and a decent case, like an Xilence Silenus... the power supply is basically trash, just some Smartbox 500W, but honestly, I'm pretty happy with it so far...

Edit:

Alright, I just posted the listing, and I bumped the price up a bit just in case someone wants to try and haggle.

It’s still sitting at 750-$267, not $333...
I guess.

Greetings.

What kind of value could I expect for this laptop?

Dell Inspiron

Intel Core i7 1.6

ATI mobility radeon hd 4650

15.6''

4GB RAM

500GB HDD

DVD Super Multi DL Drive

pretty decent little laptop... I don't really keep tabs on what everything costs these days so I might be totally off base here: $500

So, here's the build: Intel Core i3
GPU: AMD Radeon HD5450
Motherboard: ASUS M4N68T
RAM: 1x4GB DDR3 1333
PSU: Stronger SPSN-060P

What's this worth?

Hard drive and enclosure?

If they aren't total junk, I guess it might work $400.

What kind of power supply are we talking about here? Every time I try to Google it, all I get are these insane units rated at 60A on 12V... 🤷

My desktop and laptop are both running at the same time, and my internet is absolutely crawling. I called Comcast and they’re insisting everything is fine on their end, but things are still lagging like crazy. When I kill the Wi-Fi on the laptop, the desktop runs just fine. Any idea what I should do?

You can't really look at it that way. Most units use dual rails, and manufacturers tend to be a bit inconsistent—some list the total maximum current, others focus on peak wattage, or they provide both depending on how they want to market it...
as if for example

David Sanders4 said:You can't look at it that way. There are two different rails, and some manufacturers list the total maximum current, the maximum power output, or both...
like for example

I know, there are two rails—one at 25A and one at 35A.

Adam Moore3 said:I'm aware—there are two different ratings here, 25A and 35A.

Yeah, but it can't actually pull 60A. It tops out at 41.5A. To put it visually: it’s like being able to lift 55 lbs in your left hand and 75 lbs in your right, but if you try to pick up both at once, you're stuck at about 90.

David Sanders4 said:Yeah, but it can't actually deliver 60A, only 41.5A... it's like saying you can lift 50lbs with your left hand and 70lbs with your right, but together you can only manage 41...

Wait, wait, what kind of logic is that?

Adam Moore3 said:Hold on, what kind of logic are we using here?

Because that's simply the maximum stable output the power supply can handle.

I get what you're saying, but how on earth are you getting 41.5 A? Is that just a rough estimate? 😬

Adam Moore3 said:I get what you're saying, but how exactly are you calculating that 41.5 A? Is that an actual measurement, or just a rough estimate on your part? 😬

You’ve got the power, you’ve got the voltage... now it’s just down to the math.

Greetings, everyone. 🙂
I would appreciate your professional assessment regarding the following hardware configuration:

Motherboard: ASUS ROG Strix
Processor: Intel Core 2 Duo, 3.1GHz
RAM: 4GB DDR3 G-Skill Ripjaws
GPU: ATI Radeon Sapphire 7750 1GB GDDR5
Hard Drive: Hitachi 500GB 7200 RPM
PSU: EVGA 450W
Case: Unspecified, likely a standard model. 😁

The Computer is roughly a year old but has seen very little use—only a few months at most. The previous owner took a job on a cruise ship shortly after purchasing it, so they are selling the PC in favor of using a laptop.

Thank you.
