I don't know if he needs 750.... I'd think that a good 550W PSU would be fine. I think the issue is that the current cheap PSU might not even give him the 400 watts it's promising.

The PSU is on the low side but the well known brands typically have decent parts

The risk changing the PSU is that it might have a proprietary connector

Oh s***! You may be right. Good catch!

Lenovo Ideacentre 700 Series - Power Supply Unit (PSU) Replacement Options
‎05-05-2016 01:08 PM

I recently purchased a Lenovo Ideacentre 700 series desktop computer from Best Buy. Though the performance seems to be okay, I've found one 'feature' that is extremely frustrating...the motherboard has a proprietary PSU connector. The 725W aftermarket PSU I purchased can't be installed because the Lenovo motherboard has a 10+4 pin connector for the PSU whereas the aftermarket PSU has a 'standard' 20+4 pin connector.

Since Lenovo advertises this as an "Easy to Upgrade Powerhouse", do they sell an adapter to use aftermarket PSUs?! If not, is anyone aware of an aftermarket solution that I can purchase? I would think that enough people have encountered this issue that someone would offer a plug-and-play adapter cable.

I've already reviewed the following post on this forum, but it primarily desribes a solution that involves cutting wires and using a paperclip as a jumper. It also mentions a 24-to-10 pin ATX adapter cable at a site called Moddiy, but a later post says that this adapter unfortunately doesn't work.

Is anyone aware of an adpater that will work?

That's not how 400W PSU's work. It'll deliver up to 400W power to the components in the PC but it might draw around 500W from the wall to do that.

As long as you're not planning to overclock, I think you'll be fine. Heck mine only draws 485W peak from the wall and that's with a large hungry overclocked GPU.

*possibly (most cheap PSUs don't even reach their max output. Didn't Linus do a video on this? And who was talking about how much it pulled from the wall??)

I was dispelling a common misconception around what the 400W means. Do your own homework before you disagree with another poster trying to help the TC please.

What? Where did anyone in this thread say anything about the PSU pulling 400 watts from the wall? Nowhere.

Is this a good one to get? I don't know what overclocking is, so I might not be doing that if it's a manual thing.

This was in the link Clunker posted
"The 725W aftermarket PSU I purchased can't be installed because the Lenovo motherboard has a 10+4 pin connector for the PSU whereas the aftermarket PSU has a 'standard' 20+4 pin connector."

So I plan to get the adapter also mentioned in that thread.

Sound like a good plan? Should I get a better one?

Edit: Side question. Does this come with a cooling...device? I don't know if pre builts do. Never heard it being discussed. Should I get one? I live in the hot side of Arizona.

Don't worry about it.

Um.... well....

Here's the thing. It's probably better than what's in there now. But it's not a PSU that many people here would buy. It's a Tier 6 on the LTT website....

https://linustechtips.com/main/topic/631048-psu-tier-list-updated/

There's also some other stuff to consider...

1. I can't tell how big that Lenovo case is in real life. Make sure a standard ATX power supply is going to fit in the case. You may need to measure the PSU that's in there now. I guess if those other guys did it in that other thread then it's probably fine. But it doesn't hurt to double check.

2. That EVGA 600W is what's called non-modular. That means every single cable is attached to the power supply whether you need it or not. It doesn't impact performance, but it can be a true pain in the ass cramming all those unneeded cables into the case. People tend to like modular PSUs because you only plug in the cables you need to the PSU, but modular PSUs can be slightly more expensive because of that.

As an example, you can buy this Tier 1 Seasonic 650W Fully Modular Gold PSU for $54.99 after a $20.00 rebate.

...and as I'm typing this, I'm really starting to dig that PSU. I kind of wish I was building a PC right now. That's honestly what I would buy if it will physically fit in that case.
