PSU good enough to upgrade GPU?

[YelnifCh]

Hi, my setup is:

Processor: Quad Core Athlon II
RAM: 8GB
GPU: Radeon HD 7770 1 GB
600W PSU

I've had this PC for a while now and I'm thinking about upgrading the GPU to an HD 7850, but I was concerned that my 600W PSU would not be able to power the more power hungry card successfully. Does anyone think that the 600W PSU would still be enough? If so, could you suggest a more suitable PSU?

600W is plenty, but you also need to make sure the PSU is putting out enough amps on the +12v rail. For a 7850 it's recommended that the psu has 21A. Most 600W psu's should be putting out at least that much.

You can find this information on the sticker attached to the PSU usually. If you are unsure how to read the info, feel free to post a pic of the sticker, or give the make/model of your PSU and I (or someone else) can help look it up.

600w should be way more than you need. the cpu takes what 95w, motherboard 20w, 10w per fan 20w per hdd thats only about 160w for the basics.
add in a gpu and your looking at 400w max, so yeah 600w should be more than enough.

What brand is the 600w psu?
If it is a really cheap brand then you might have issues, otherwise if it is decent at all then you are completley fine.

Make and model of supply please.

If the power supply labelled as 600W came with the Athlon II x4 or phenom computer then it is probably low quality, it is probably best to get a new power supply.

Well, this is the sticker on the side of the PSU. Hope this answers your question.

I wonder, what makes you think a PSU that came with an Athlon II X4 be bad quality?

Can't say for sure how many amps that PSU has on the +12v rail(s) as it doesn't tell us how many watts it provides on just the 12v rails alone. It just says 600W for everything without breaking it down by rails like most new PSUs do. I hate when PSU manufacturers do that on their stickers. Kind of shady.

But if I had to guess, It likely is putting out more than enough. Only needs 21 amps and that one is claiming dual 16amps.

No, I googled it and it came across as £24 , that's pretty cheap for a 600W PSU. Well, that does seem a bit dodgy, so I'd advise getting a new PSU, the XFX 550W should be enough.
