Should be plenty.

Do you have a link to that PSU? I have never heard of the brand... and usually if I haven't heard of it its not really a good brand.

that's a link for that psu i told.

Zebronics is one of the worst companies, the psu is only 16a meaning it's closer to a 250w psu. I wouldn't trust it.

DiaSin · Sep 26, 2013

Whats the base voltage on the wall outlets where you live? The amperage it outputs at the voltage level in an american socket is only 22amps.. But that goes up to 35 amps in a 230v socket, which would be enough, assuming it could live up to its ratings..

The biggest issue I have is that it does not mention an 80+ rating, which would certify that it was capable of putting out never less than 80% of its maximum power. I would not buy a PSU that was not at least 80+ Bronze rated.

Personally on a budget the lowest I would go would be the Seasonic S12II 520w PSU.

so can i run sapphire 7750 on it?

Deemo13 · Sep 26, 2013

Oh wow, 16a on a 12V rail. Didnt know it was that bad. I figured if it was at least halfway decent it would be able to run a 7750. This might be one of the worse power supplies I've seen.

Lowest power supply I would recommend for the price is a 450W Antec VP-450. It should run quite a range of cards and has good 12V power. Its also decently cheap at a good price.

If you are still asking if you can run it on the zebronics, the answer is no. It will not get enough power, and with that psu.. the whole system may fry within a matter of weeks.

This is incorrect info. 230v psu will not work in the US since they use 120v. The psu would probably kill itself. The max is 15 or 20a but this is ac and a psu converts it to a lower voltage dc. If you do the math, this is why you can find 1500w psu still on a single socket. But you can assume since he linked to an indian site that he is in india which does use 230v.

80+ rating is efficiency not its max power output. The wattage rating will be it's output but you will be taking more watts off the wall socket. So 100w output at 80% eff is 125w off the wall. Most good psus will actually output higher than the rated wattage of course it's not recommended as this would be overworking it and lead to a premature death. Also psu power ratings are not governed by anyone and can list peak or sustain, false 80+ certifications (one reason this cannot gauge quality) and can be misleading as is the case with this low quality psu that has more power on the lesser used 3.3v and 5v rails. This is why it's important to buy from a reputable company and also highlights the importance of third party psu reviews.

Did you read the link he posted, according to that chart it looks like the amperage is different based on the voltage of the socket it is plugged into.

As for the rest, thank you for correcting that misunderstanding.

k1114 · Sep 26, 2013

You misunderstand the label. The psu supports 115v/230v, 10/6a input but the output is always the same. This is the sole purpose of any psu, to convert the different input power to the output power needed.

k1114 · Sep 26, 2013

I'm not sure what price range psu you are looking for but this seasonic 400w is one of the cheaper good models. http://www.flipkart.com/seasonic-ss400bt-psu/p/itmdfbeqezgmgggf?pid=PSUDFBEPQB2ZCCMS&ref=ed380041-c06b-4e4a-9375-6d0d01a0963a

PLZ MAN GIVE ME WITHIN 2000

Deemo13 · Sep 27, 2013

It does not seem that there are any decent units within that pricerange on that website that I would recommend.

Within 2000rs i would say get this http://www.flipkart.com/cooler-master-cm-350-plus-watts-psu/p/itmd5xz5zseyzua6?pid=PSUD5XZ4ZYUBRN6T&otracker=from-search&srno=t_1&query=cooler+master+600+watts+psu&ref=cba62cae-6cd5-4703-b180-ca99a51ceab4
Its not a particularly good quality psu but i have the elite one and it runs my sig rig just fine.But however if you can stretch your budget definitely get a good quality psu.Friends don't let friends buy poor quality psu's.

Nayanmanna · Sep 27, 2013

If it is 2500 then what will u preffer for me.

k1114 · Sep 27, 2013

http://www.flipkart.com/antec-bp300p-300-watts-psu/p/itmdcxzujzxdjesg?pid=PSUDCXVMUGW6ZVYB Antec bp300p. It is actually more power than that cm350. The antec is dual 18a rails. The cm is 10 and 13a rails. It's also better quality and higher efficiency.
