Graphics card question

[Brandon Beckius]

How does not meeting amp requirements  for a graphics card affect it, i have a 240w pcu, can i run a sapphire hd 7850 with it?

Wattage "requirements" listed on the product page are suggestions more than anything. What's more important about a PSU is that it's decent enough to run a system you care about. An HD 7850 isn't a very power hungry card.

Extremely underrated power supplies can cause instability in components, and could possibly damage the power supply.

More than likely no permanent physical damage would be done to anything if you only run a too-small PSU for a short period of time, except that you may experience a head crash if you are using a hard disk.

However, your software and/or files could be damaged, including your OS installation. If the PSU is completely unable to keep up, you can experience RAM instability, which might lead to a corruption of OS files. This is very hard to diagnose, and can be devastating, leaving your computer essentially unusable until you install a new OS. Your processor might also be experiencing severe instability, and produce erroneous output, which could also corrupt OS files or other software/data.

Bear in mind, however, that these examples are quite extreme and would require a very underpowered or unstable power supply before they are likely to occur.

It would help us if we knew more about your machine than just the graphics card:

• What processor are you using?
• How much RAM are you using?
• Liquid or air cooled?
• RGB?
• How many SSDs/HDDs do you have connected?
• Are there any other expansion cards?
• Are any external components being powered by the computer?

I would recommend a 350 watt power supply.

oem pc like dell hp acer

oem pc like dell hp acer

its a dell optiplex 7010 sff

its a proprietary psu

meaning you cant just plug in a cmx 350W even if the size was right, because the cables are different.

 

you'd have to find a dell psu that is higher wattage made for the optiplex 7010 sff

 

you are not shit outta luck though, because you can hook up an aftermarket psu to the dell, it just takes some soldering skills. you maybe able to find a conversion kit, but they are rare to find, if any.

 

you could also maybe just hook up the gpu to a separate psu.

I once found dell optiplex 7010 power supplies that had more than the original amperage, but ive since lost the website, ive been looking for it.

yeah i mean the dell still uses all the regular voltages and such, its just the connectors are different.

 

like i said i've run into custom adapters online, I have a oem hp and wanted to use gtx 650 gpu.

i will see what i can find.

 

something like this

gotta realize though your new aftermarket psu will most likely not fit inside your oem case.

 

use search term ATX POWER ADAPTER and have a look

 

again something similar
