Running Ati 5750 on a 300 watt PSU

[dude101]

I asked the same question a few weeks ago when I was upgrading from an Ati 2400 pro to HIS 5670. I have a 300 PSU and I asked whether it could handle the ATI 5670. I got mixed answers, some said yes and others advised for a PSU upgrade. The HIS 5670 consumes 64 Watt max under load and so I kind of knew my 300 watt will be fine. Indeed, everything turned out fine!!!


Now the new problem:


I want to now upgrade to the ATI 5750 (by MSI). Actually, I have already ordered this GPU from newegg.ca. The 5750 consumes 86 watt max. So, it only consumes about 22 more watts than my ATI 5670.

So, will my 300 watt PSU be able to run the ATI 5750 (86 watt max) fine? (considering it ran the ATI 5670 more than fine (64 watt max))


FYI: I will buy the PCI Express power adapter that converts two 4-pin Molex power supply connectors into a single 6-pin PCI Express connector to power the ATI 5750.


These are my specs:

Dell Inspiron 530
Intel Core 2 duo e4600 @ 2.4GHz
3 GB ram @ 800Mhz
300 watt PSU


If you do suggest me a new PSU, please suggest me one considering the size of my case. It is a Dell Inspiron 530 and it doesn't look that big. I dont know what kind of PSU to look for, for compatibility reasons.

You should be alright with it if you have a quality PSU with an 80 Plus rating.
If you wanna actually find out for yourself about the requirements of your pc regarding your PSU, read through this article that Tom's posted a while back. it explains everything you'd ever need to know about a PSU and you're PC's consumption

Hey slick3,

glad to help you. I have been running the XFX 5770 on the same psu for almost 4 months and it hasn't let me down.

The fans in the Dell inspiron 530 tower get the heat out but they are very much audible during heavy gaming, such as bad company 2, MW2, stalker,etc.

If your 300 psu is from dell, then you are FINE!

Go buy the 5770 now, its worth the extra over the 5750.

I believe my PSU is a lite on HP that delivers 19A ... do u think i can get away with the HD 5750 ? ( maybe i'm gonna push it too far with the HD 5770 )

I am not sure about HP and their power supplies.

My dell has a 300 watt psu which also delivers 19A. I am running it fine so far. Again, I can't say anything about HP's power supply even if it delivers the same wattage and amps as mine.

My best suggestion would be to go buy it and try it out. If it doesn't work then simply upgrade the power supply (?).

One more thing, consider buying a Nvidia gtx 460 768mb for around $200 (or the 1 gig version for like $240) and upgrade your power supply to support the gtx 460, you would have graphics power exceeding Ati 5850!

why would you upgrade to a 5750? when you just bought a 5670 :/ isnt that sorta a waste of money?

I need help guys, I have an Intel Core 2 Quad Q8300 2.5Ghz, 2GB DDR2 of RAM, and a case Foxconn TLM-776 with a PSU of 400Watts, so, the question is: My PC will handle the 5770 or the 5750 without problems? Please answer
