[SOLVED] How can I add another (SSD) drive in this PC safely?

Jun 13, 2019
Hi, I'm planning on adding a second drive (a 120G SSD) and move Windows there because the HDD is pretty slow.

Some info about the PC:

Operating System
Windows 10 Pro 64-bit
AMD A8-7600
Kaveri 28nm Technology
4.00GB Single-Channel DDR3 @ 920MHz (10-11-10-30)
MSI A68HM-E33 V2 (MS-7721) (P0)
SMS19A100 (1366x768@60Hz)
512MB ATI AMD Radeon R7 Graphics (MSI)
931GB Seagate ST1000DM003-1SB10C (SATA)
8GB Microsoft Virtual Disk (File-backed Virtual)
Optical Drives
Realtek High Definition Audio

The PSU:

There's currently a Seagate HDD already installed. And if I'm not mistaken these are the power and data cables connected to the motherboard. Is that correct? (highlighted red)

(this one seems to be connected to a 4-pin molex)

Here's what I'm planning to do:

• I buy a Kingston A400 120GB SSD 2.5" SATA3
• I buy a molex to SATA connector and a new data cable
• I connect the power cable to this, which I presume is an unused molex connector:

• Then place the SSD here:

Is this a safe and correct way to do it? Because I don't want to risk burning or melting anything.

Thanks for any help!

edit: To anyone wondering what kind of Molex to SATA cable to buy, definitely check this video first:

I'll update this thread if I can. Thanks again everyone.

Yes you can, SSD's use next to no power, which is good as your PSU puts out next to no power. A good PSU will put out 80+% of it's rating on the 12V rails, yours is doing about 50%, personally i'd rate that PSU as being about 350W not 600W.

So don't add anything else, but an SSD won't hurt.

SSDs draw very little power. It will run fine on your PSU as external ssds can even be powered by USB in some cases.
You just need to find a sata data cable (the one you highlighted in red is correct) and plug one end in the motherboard and one end in the ssd.
Does your PSU have any SATA power connectors? The current HDD seems to be using a Molex to sata power adapter.

Yes, but schedule a replacement for that PSU in the very new future.

As stated, it's name plate rating is likely a "Peak Rating" that is over (perhaps significantly) what is is capable of delivering continuously. Good quality PSUs usually state both continuous output power ratings AND a peak output rating for a specified time period. Since yours lacks this, it's likely that the output rating is actually the peak output of the PSU, instead of its continuous output rating. A very deceptive practice on the part of the manufacturer, if you ask me.

Hi, just making sure I'm doing this all correctly, as I haven't seen any answers on the internet regarding this. Here's my previous post.

So I recently bought a Kingston A400 SSD, a SATA data and a molex to SATA connector for power.

Here's the pic of the inside

Here's a pic for the power, is this the right orientation?

It seems it's also connected to the molex on the right. Is that a cause for concern?

And for the SSD part, are these the correct?

Thanks for any help. Just making sure I don't mess or fry anything up
