psu Psu info help

[Dotmidi]

Could someone explain to me what this psu is capable of ? Could it handle any sort of GPU's? Thanks in advance

[79wjd]

It can handle 230w over the 12v rails (which is what really matters). So it could handle a low power GPU like a 1050, but it's far from ideal.

I wouldn't trust this thing ever. It's a 240w no name gray box.

Edit: I'm an idiot it's bronze so still pretty much nothing

It is capable of making your Fourth of July unforgettable.

A GPU without a 6/8 pin PEG cable.

"80+ bronze, and on fire while being at least 80% efficient" sounds about right here.

 

but essentially, this is what it comes down to:

+12V1 12A -> 144W 12 volt rail for the mobo plug, and whatever other plugs this horror show has

+12Vcpu 16A -> 192W 12 volt rail for the cpu plug seperately

these two rails combined cannot exceed a combined wattage of 230W

+5.08Vsb 2.5A -> 12,7W 5 volt rail (it's supposed to be 5 volts, not 5.08.. cmon china..) as standby, this one is pretty much standardised across the board, it's rare to find more, avoid like the plague if significantly less.

-12V 0.2A -> 2.4W -12v rail, this is something that "used to be necessary" but has gone the way of the dinosaurs.

these two rails combined cant total more than 15W (so that 0.1 watt you win with having 5.08 volts instead of 5 volts cannot be used... china.. is stronk..)

 

and offcourse, to cap it off, the total between these 4 rails cant go past 240W, not that i'd advise you to use this thing anywhere close to that..

the input current spec seems a tad high for being 80+ bronze as well... the corsair RM750x for example only lists 10A at 110V, and 5A at 230V, with even the terrible CX500 (green label) only claiming 5A at 230V.

Simple conclusion - a crap PSU, don't throw a GPU on it, change the PSU ASAP

What makes you think it is crap?

Extremely low 12V output

Heard of the brand before, it's a Chinese brand which makes lots of crap PSUs

[mr moose]

Don't know enough about it to know if its a crap PSU or not, we only know what @djdwosk97   has already pointed out. 

 

Do you know where it came from (what it's in) and what company made it?

*Taiwanese.

Superflower, CWT, Seasonic, Delta, HEC/Compucase, Liteon, FSP and Andyson are all Taiwanese companies, so Idk why  you think that is a bad thing. 

 

It is an OEM unit used in a small factor form prebuilt (and not just any old prebuilt, it was from a Lenovo Thinkcentre), it isn't designed to output lots of power. 

 

Also the OP cannot exactly replace it, it isn't a standard size and the connectors are not standard.

Well, it's it s 240w PSU, in which it has a 230w / ~19A rating on the 12V rail. Usually power supplies with that close of a rating on the 12V rail as the rated wattage are independent / DC-DC regulated power supplies. The 12V rating is appropriate for the unit of it size.

 

AcBel is a Taiwanese company that actually makes power supplies for various of industries including the server, telecom market, the power meter inside a lot of homes, etc. They are an OEM for a lot major brands such as Dell, HP, Lenovo, etc. These sort of company will build to the specification that their customers (Dell, Lenovo...) has set for them, and typically, it is build well enough to deliver it rated power within ATX specification.

 

Regardless, this is a proprietary power supply. This is evident by the 5.08VSB rating that Lenovo specs for many of their computers, as well as the lack of 3.3V / 5V rating. You simply can't replace it (unless of course, the OP finds an adapter for it or rewired the PSU). Then there's the issue of physical form factor.

Learnt something, thanks
