Is my PSU capable of running high end graphics cards please help

I have an assembled pc having the following spec:

Processor: iCore3 2100 3GHZ

Motherboard: Intel DH61WW

RAM: 8 GB DDR 3

PCIE x16 version 2.0 slot card : xfx 9400GT 1GB

Hard Disk : 1 TB Western Digital SATA

DVD Writer

MY 500 Watt PSU has got two 12V rails as printed on the side of the PSU's cover

+12V1 => 22 A

+12V2 => 22 A

(If you need other voltage or ampere values printed on the side of the PSU, please let me know)

And 1 PCIE 6 Pin connector ( 6 pin + optional 2 pin ) - wattage of this connector is unknow to me.


Can I run any of the following cards without upgrading my PSU and damaging any of the existing components ?

HD 7750, HD 7770, HD 6790 , HD 6850, GTX 550 ti, GTX 560, GTX 560 SE, GTX 560 ti

Depends on make and model of power supply. Not all power supplies use the same grade of components.

So there is no surety of running any of those cards ? Not even HD 7750 or GTX 550 ti ?

According to the Specs of your power supply you should be able to run any graphics card that requires no more than 1 PCIe power connector. However, as others have stated, we have no way of knowing whether your PSU actually supplies the current and wattage that it is rated for. Tell us the brand and model number of the PSU and then we can look it up and make a better assessment of it's quality.

All these cards have a requirement of 500W PSU...As far as I have had experience with this: if you have good PSU AND you will not OC, your current setup will allow these cards. However, if you have bought one of those 5 cents per watt PSUs... Results may wary :)

It is a local brand -

E-Spectrum - model: ES - PSU - 500 W

This is their website: http://www.e-spectrum.in/

My model is not listed in the website. Instead there is another 500 Watt model on display -

http://www.e-spectrum.in/products/power-supply/es-psu-p...

Hope this helps.

EDIT: The model on display in the website is the same as my model. Only difference is that my 12V rails have 22 A instead of 20 A

ALSO NOTE : I am currently running xfx 9400 GT 1 GB which requires a 20 Amperes rating on the 12V rail ( as printed on the side of the card's box ). So I guess we can be sure that the 12V rail at least has the capacity to deliver 20 Amperes.

Please correct me if I am wrong.

Will brands like - Cooler Master or iBall work as an alternative ? If so which models ?

Secondly - I see that crossair CX600 has a extra fan on it top (in the picture).

Will it fit into my existing cabinet or do I have to buy a new cabinet too ?

If I can use HD 5770/6770/7770 with my existing PSU. Then why not HD 7750 ?

Secondly , do the rear end of the top cover of the cabinet needs to be open to allow air flow from the cross air PSU CX 600 which has a fan on the top as shown in the picture - http://****/api/click?format=go&key=984ed3ed6aa9a69986f88d56d10e7616&loc=http%3A%2F%2Fwww.tomshardware.com%2Fforum%2F367683-33-capable-runnin...

I think none of these cards burn more than 300W so you should be fine with any of them honestly. Don't go SLI/Crossfire though.

If I go for iBall, it will cost me a little less than CrossAir CX 600 or Cooler Master.

Is Cross Air CX 600 a stable choice for running any of the high end cards ? Please confirm.

Not really.. If you game 10 hours a day EVERY DAY, it will use 50 kWh a month. Not sure how much you pay for one kWh, but I pay $0.15. So the card would cost me just under $8 every month if I played 10 hours a day every day.

Though that's far from realistic estimation, because I personally don't game that much :) .

Well, since you have 400W total, 24A goes to 5V and 18A goes to 3.3V, the rest goes to 12V. So 12V power = 400 - 24*5 - 18*3.3 = 220.6. Divide that by 12 and you'll know total amperage for 12V rail.

220.6/12 = 18.3A.

So yea, that's what you get from chinese manufacturer. I'd not use that power supply with a discrete card, the sticker is lying.

Oh ! So HD 7750 will unable to run on ~ 18 A 12V rail current ?


Tell me something more. Will a crossair CX 600 or cooler master 600 W fit into normal normal tower cabinet or do I have to get special type of cabinet for them ?

I am asking this because unlike normal PSU the cooling fan for cross air or cooler master is on the top instead of on the rear side.

Don't get cooler master. They aren't good either. Get a Corsair one.

And the fan is on the bottom, not on the top. It will fit inside normal case easily.

And HD 7750 should be able to run on it, but I wouldn't push it. These kind of power supplies can only cause trouble - around a year ago chinese power supply almost ignited my curtain - I was lucky to see the flames in time and more the PC away from the curtains.

My God. Now I am in real trouble. The local store said that they will only be able to provide iBall and Cooler Master but no Cross Air !

Moreover I have only managed to gather money good enough to buy HD 7750 and GTX 550 Ti. Out of this two, it appears that only HD 7750 is fit enough to that PSU capability. Those PSU will take up nearly the price of HD 7750 ! I am really stuck.
Whether to go with HD 7750 without an upgrade or borrow money for the PSU. HD 7750 does not give a requirement for the ampere in +12V rail. It only says it needs a 400 Watt
PSU. See here - http://www.amd.com/us/products/desktop/graphics/7000/77...

And mine says regular 400 Watt and peak 500 Watt. Question is can the PSU perform when the HD 7750 is drawing ampere under peak load of around ~ 50 Watt. I hope HD 7750 won't go over 50 Watt under peak load.


P.S If the fan is at the bottom then it is a real problem. How come they put the fan at the bottom ! The whole hot air will circulate inside the chassis / cabinet and most importantly the hot air will blow pass the processor ! What a design ! It will heat up all the components inside the cabinet more !
